[0007] According to one aspect of the invention, the two roof parts each extend along a plane inclined relative to the pillar.
[0008] In other words, the roof is not perpendicular to the pillar.
[0009] According to one aspect of the invention, the two roof parts extend along a common plane inclined relative to the pillar.
[0010] According to one aspect of the invention, the common plane is inclined relative to the pillar at an angle of between 70° and 90°, in particular at an angle of approximately 85°.

[0022] According to one aspect of the invention, these supports are formed by a peripheral edge of the box.
[0023] According to one aspect of the invention, the supports can also be formed by transverse bars arranged at different locations in the box.
[0024] According to one aspect of the invention, the transverse support bars are rectilinear and arranged in a parallel and equidistant manner from each other.
[0025] According to one aspect of the invention, the opening between the two roof parts is formed between two parallel rectilinear edges facing these roof parts, and the transverse bars are parallel to these edges.
[0026] According to one aspect of the invention, the solar panel(s) thus rest on the peripheral edge and on the transverse bars which are then located under the solar panels.
[0027] According to one aspect of the invention, each box comprises at least one air inlet slot configured to allow air to flow into the box and to allow the air to be heated by the solar panel(s) that close the box. A sufficiently fine mesh screen is arranged on the inlet slots to filter out any external objects or bodies. External crossbars supporting the boxes are configured to protect the air inlet slots from rainwater infiltration.
[0028] According to one aspect of the invention, the air inlet slot extends along an edge of the box.
[0029] According to one aspect of the invention, each box has at least two air inlet slots arranged along two opposite sides of the box. For the end panels, an additional slot could be added. The slots can be of the same dimensions or different from each other.
[0030] According to one aspect of the invention, the box comprises an air collection slot configured to allow the evacuation of air coming from the inlet slot or slots and having circulated in the box in summer heated by the solar panel or panels.

[0034] According to one aspect of the invention, the air inlet slots and the collection slot(s) are parallel to each other.
[0035] According to one aspect of the invention, the air inlet slots and the collection slot(s) are perpendicular to the transverse support bars for the solar panels.
[0036] According to one aspect of the invention, the collection slot(s) are located equidistant from the air inlet slots.
[0037] According to one aspect of the invention, the installation further comprises a longitudinal beam connecting to the central pillar and the longitudinal beam extends in the space between the two parts of the roof, in particular parallel to the two facing edges of the two roof parts.
[0038] According to one aspect of the invention, the installation also comprises a transverse beam connecting to the central pillar and supporting the two roof parts.
[0039] According to one aspect of the invention, the installation thus comprises the central pillar which supports the longitudinal beam and the transverse beam.
[0040] It is thus possible to form the installation with a total number of pillars / beams equal to three. This number can be four in the case of separate transverse beams, dedicated to each part of the roof.
[0041] According to one aspect of the invention, the longitudinal beam and the transverse beam intersect at right angles.
[0042] According to one aspect of the invention, the air discharge slot in the roof box is open to the transverse beam which is hollow.
[0043] According to one aspect of the invention, the beams are hollow as is the central pillar, so that the air having circulated in the box and which is heated by the solar panel(s) circulates through the air evacuation slot towards the transverse beam.
[0044] According to one aspect of the invention, this transverse beam is hollow and thus forms, in whole or in part, a channel for discharging the heated air. Each transverse beam can be equipped with a fan for discharging the air towards a main duct, in particular in the longitudinal beam.
[0045] According to one aspect of the invention, this discharge channel in the transverse beam extends into the longitudinal beam.
[0046] According to one aspect of the invention, the longitudinal beam is configured to discharge air circulating therein to an air heat recovery system.
[0047] According to one aspect of the invention, this system comprises, for example, a heat pump placed, for example, in a building to heat it.
[0048] According to one aspect of the invention, the installation comprises a fan, in particular an electric fan, configured to suck air towards the air circulation channel in the longitudinal beam.
[0049] According to one aspect of the invention, this air suction makes it possible to create the air flow from the air inlet slot(s) on the roof box towards the channel of the longitudinal beam.
[0050] According to one aspect of the invention, the fan is a rotating blade fan.
[0051] According to one aspect of the invention, the fan is placed within the longitudinal beam. Other fans may also be placed on each transverse beam.
[0052] According to one aspect of the invention, the pillar and / or the longitudinal beam and / or the transverse beam are each made with an assembly of plates, in particular based on bio-sourced materials, wood or others such as high-pressure laminates of paper and resins intended for exterior cladding.
[0053] According to one aspect of the invention, this assembly of plates forms an external envelope of the pillar and / or the longitudinal beam and / or the transverse beam.
[0054] According to one aspect of the invention, the assembly further comprises beam elements, in particular made of wood, arranged in parallel on a contour, for example rectangular, and between which the plates are arranged. The beam elements can also be made of steel, in particular for the central pillar where heat exchange is not critical.
[0055] For the central pillar, these beam elements measure, for example, 3 to 6 meters or more.
[0056] According to one aspect of the invention, honeycomb structures, for example made of plastic, are arranged in the interior space of this envelope. This makes it possible to reinforce the pillar and / or beams and, at the same time, to allow air circulation.
[0057] According to one aspect of the invention, the honeycomb structure has a rectangular or square outline.
[0058] According to one aspect of the invention, the honeycomb structure has a grid or honeycomb shape.
[0059] According to one aspect of the invention, the honeycomb structure occupies an entire interior section of the pillar or beam.
[0060] According to one aspect of the invention, several honeycomb structures are provided in the hollow pillar and / or the hollow beam, in particular at a distance from each other.
[0061] According to one aspect of the invention, the honeycomb structures may be made of reinforced plastic, in particular with glass fibers.
[0062] According to one aspect of the invention, the assembly of wooden plates is reinforced by reinforcements, in particular metal reinforcements.
[0063] According to one aspect of the invention, the metal reinforcements are on an external face of the plate assembly. Alternatively, the metal reinforcements may be on the internal face, in particular for aesthetic or functional reasons when thermal conduction is not affected.
[0064] According to one aspect of the invention, the metal reinforcements may represent a V or cross shape.
[0065] According to one aspect of the invention, the metal reinforcements are configured to mechanically reinforce the pillar and / or the longitudinal beam and / or the transverse beam.
[0066] According to one aspect of the invention, the metal reinforcements may also serve to interconnect the longitudinal beam and the transverse beam to the central pillar.
[0067] The invention is particularly advantageous because it allows for dual energy production, namely energy in electrical form thanks to the solar panels and energy in the form of heat recovered by the circulation of air which recovers the heat released by the solar panels.
[0068] According to one aspect of the invention, the energy produced can be used for industrial, commercial or residential applications. The installation according to the invention can be placed, for example, in a parking lot, for example, of a shopping center, a train station, an airport or an industrial complex.
[0069] According to one aspect of the invention, the installation comprises an electric charging station or several electric charging stations configured for charging one or more electric vehicles parked in the spaces covered by the installation.
[0070] According to one aspect of the invention, the charging station comprises a charging socket to be connected to an electric vehicle.

[0072] According to one aspect of the invention, the inverter is arranged on the installation.
[0073] For example, the inverter is attached to the central pillar of this installation.
[0074] According to one aspect of the invention, the inverter may be placed at a height sufficient to be taller than the average height of a person.
[0075] According to one aspect of the invention, the inverter is placed, for example, 2 m or more from the ground.
[0076] According to one aspect of the invention, the charging terminal is placed on a base of the installation.
[0077] According to one aspect of the invention, the charging station is placed against the pillar. Very fast charging stations, which are more bulky, could be placed longitudinally away from the pillar, at a distance equal to or less than the width of a parking space. Compact charging stations, especially when they are powered directly by the batteries with direct current without passing through the inverter, can be integrated into the central pillar.
[0078] According to one aspect of the invention, the roof is configured to cover 1 or 4 parking spaces for motor vehicles.
[0079] According to one aspect of the invention, each roof portion is configured to receive a plurality of solar panels, for example 4 or 5 solar panels.
[0080] According to one aspect of the invention, the roof has a total length of at least 2 meters, measured parallel to the longitudinal beam.
[0081] According to one aspect of the invention, the roof has a dimension measured along the transverse beam of at least 4 meters, or 5 meters.
[0082] According to one aspect of the invention, each solar panel is configured to have a power density of at least 400 Wp (Watt-peak) per panel.
[0083] According to one aspect of the invention, this power density can be chosen at 700 Wp nominal.
[0084] According to one aspect of the invention, the roof is inclined and has a lower edge which is closest to the ground when the installation is mounted. This lower edge is at a height of approximately 4.2 meters from the ground. This makes it possible to meet safety standards.
[0085] According to one aspect of the invention, the central pillar is hollow and defines a housing for receiving one or more battery modules.
[0086] According to one aspect of the invention, each battery module is connected to the inverter, itself connected to the solar panels which are then used for electrically recharging the battery module(s).
[0087] According to one aspect of the invention, the battery module may be sodium technology. Alternatively, lithium battery technology is used.
[0088] According to one aspect of the invention, the honeycomb structures are configured to define the different housings receiving the battery modules.
[0089] According to one aspect of the invention, the central pillar comprises housings on several levels for receiving the battery modules.
[0090] According to one aspect of the invention, the central pillar is fixed on a base at least partially buried.
[0091] According to one aspect of the invention, the base is configured to be buried in the ground and is of relatively low height, this height being in particular less than 600 mm.
[0092] According to one aspect of the invention, the installation comprises a buried anchoring system configured to keep the base of the central pillar anchored in the ground.
[0093] According to one aspect of the invention, the anchoring device comprises buried cables, each with one end secured to the base of the installation and another end attached to a dowel configured to be fixed deep in the ground.
[0094] According to one aspect of the invention, there are four cables. In particular, the anchor cables also serve as an electrical ground conduit for the installation. The anchor cables of one of the installations could be several meters longer than the others to serve as a lightning rod. These particular anchors are connected by wiring to a mast on the roof to channel lightning.
[0095] According to one aspect of the invention, the base of the installation projects a certain height from the ground when the base is fixed to the ground.
[0096] According to one aspect of the invention, the base has, at this emerged height, a shape chosen to serve as a stop for a wheel of a vehicle.
[0097] So when a vehicle approaches the central pillar to park under the roof, the wheel of the car closest to the central pillar comes up against the base so as to signal to the driver that he cannot approach the central pillar any further.
[0098] This provides reliable security to prevent a vehicle from hitting the central pillar of the facility. Additional safety posts can be added if necessary.
[0099] According to one aspect of the invention, the base has a cross-shaped edge configured to serve as a stop for a vehicle wheel.
[0100] According to one aspect of the invention, the installation uses durable materials such as wood and metal.
[0101] According to one aspect of the invention, the parts of the installation can further be reused, repaired or recycled.
[0102] According to one aspect of the invention, the wood is used in the beams and pillars and may be wood treated using copper oil under high pressure in an autoclave.
[0103] According to one aspect of the invention, the wooden panels under the solar panels and which form the box are protected by a metal shield to avoid thermal stress on these wooden panels.
[0104] According to one aspect of the invention, the installation comprises a system for cleaning the solar panels.
[0105] According to one aspect of the invention, the cleaning system is of the hydraulic type.
[0106] According to one aspect of the invention, the cleaning system comprises a member for projecting liquid onto the solar panel(s).
[0107] According to one aspect of the invention, this liquid projection member comprises a tube placed along an upper edge of the roof, or of each roof portion.
[0108] According to one aspect of the invention, the tube is provided with a slot, in particular a longitudinal slot, along this upper edge of the roof.
[0109] According to one aspect of the invention, a liquid is projected through this slot, in particular under moderate pressure, in order to clean the surface of the solar panels, in particular without damaging them.
[0110] According to one aspect of the invention, the tube is connected to a water reserve, for example a rainwater recovery reserve.
[0111] According to one aspect of the invention, the connection between the reserve and the projection tube(s) is made by a conduit housed in the central pillar.
[0112] According to one aspect of the invention, the conduit, preferably rigid, is made of reinforced plastic, for example reinforced with glass fibers. The conduit can also serve as reinforcement for the central pillar by connecting to the wooden beams through honeycomb composite plates.
[0113] According to one aspect of the invention, the conduit extends from the bottom to the top of the central pillar.
[0114] For example, the conduit has a height of at least 80% or 90% of the total height of the central pillar. Advantageously, the volume of water in the conduit does not exceed 90% in order to contain the volume of frozen water. The choice of composite materials for the conduit or reservoir must allow it to withstand freezing stresses while contributing to the rigidity of the structure of the main pillar.
[0115] According to one aspect of the invention, one or more pipes may be provided to connect the water projection tube to this vertical conduit.
[0116] According to one aspect of the invention, the pipe(s) are arranged in the box which supports the solar panel(s).
[0117] According to one aspect of the invention, the cleaning system may comprise two water spray tubes, one for one part of the roof and the other for the other part of the roof.
[0118] According to one aspect of the invention, the installation comprises a water pump configured to pump water from the reserve and direct it to the cleaning system.
[0119] According to one aspect of the invention, the installation comprises a gutter configured to collect rainwater flowing over the roof, and to direct the collected rainwater into the central foot reserve.
[0120] According to one aspect of the invention, the pump for pumping water is of the electric type. It can be activated by a dust sensor and / or at predefined time intervals.
[0121] According to one aspect of the invention, the recovered water can be filtered before reaching the reservoir. Advantageously, the water level in the reservoir is controlled by a distance sensor located on a main control box installed at the top of the central pillar.
[0122] According to one aspect of the invention, the installation comprises one or more thermal control cameras, in particular fixed to the top of the central pillar, and configured to measure the temperature on the surface of the solar panels.
[0123] According to one aspect of the invention, this thermal camera is fixedly mounted on the central pillar or mounted in a mobile manner, for example to allow it to rotate and be oriented towards the solar panels. In particular, the thermal cameras are fixedly mounted on the central pillar or the camera is mounted in a mobile manner, in particular when it is a single camera.
[0124] According to one aspect of the invention, the thermal camera makes it possible to continuously monitor the potential appearance of hot spots on the surface of the solar panels.
[0125] Hot spots can pose a danger to the installation. The thermal camera can potentially detect the presence of animals (birds, rodents, insects) that can damage the installation through the deposit of waste, nests, or by gnawing on cables. The detection will be transmitted to an electronic module that triggers, for example, an animal-repellent sound. It can also help alert users to malicious human activity (theft, breakage). Temperature sensors may be used to monitor the temperature in areas where it is needed.
[0126] According to one aspect of the invention, the installation comprises a control unit configured to receive information from the thermal camera and trigger an alert when a hot spot has been detected on one of the solar panels.
[0127] According to one aspect of the invention, the roof comprises a fire alert system configured to generate an alert in the event of a fire or abnormal temperature on the roof.
[0128] According to one aspect of the invention, the fire alert system includes wires that snake under the solar panels.
[0129] According to one aspect of the invention, these wires are configured to melt in the event of high temperature.
[0130] Melting the wire creates a short circuit, which triggers an alert. The wires can also be connected to the control box to provide pre-alerts (for example, by email, telephone, etc.).
[0131] According to one aspect of the invention, the wires of the fire alarm system are placed in the path of the air flow under the solar panels so that its wires generate turbulence in this air flow promoting a better heat exchange between the air and the solar panels. The wires are in particular retained by devices on the lower part of the boxes in order to remain at a controlled and sufficient distance from the solar panels.
[0132] It is possible to provide disturbance elements other than these wires or in addition to these wires.
[0133] The invention also relates to a set of installations comprising a plurality of installations as described above, these installations being in particular arranged side by side.
[0134] For example, longitudinal beams are placed in line with each other.
[0135] It is therefore possible to recover heated air at the end of this succession of longitudinal beams.
[0136] It is thus possible to create a large area of solar panels housing several parking spaces.
[0137] The recovery of calories thanks to the invention can, for example, be used to heat buildings using the air circulating under the solar panels.
[0138] The air used to transport calories from solar panels could be replaced by any other suitable fluid, for example a liquid.
[0139] The invention allows a modular solution in terms of installation of the installations, each installation being able to be autonomous.
[0140] The invention makes it possible, in particular, to place identical installations side by side, with a number chosen to cover predetermined needs. This makes it possible, in particular, to avoid having to resort to a centralized system sensitive to each partial fault in the installation.
[0141] According to one aspect of the invention, each installation is energy-autonomous for its operation.
[0142] According to one aspect of the invention, each installation is autonomous in terms of electronic control.
[0143] According to one aspect of the invention, each installation is mechanically autonomous.
[0144] The collected rainwater can be used to wash cars, cool charging stations, batteries, the inverter or supply toilets in surrounding buildings.
[0145] The installation may include information or warning light devices which are electrically powered by the battery modules.
[0146] The installation may include a control unit such as a computer, capable of collecting information from the various sensors and equipment in the installation.
[0147] Information transmissions can be carried out wirelessly using an encryption protocol to a central antenna.
[0148] The installation may include a screen configured to display information, for example, on air quality or the weather.
[0149] The installation is particularly ergonomic.
[0150] The invention allows several vehicles to be recharged at the same time, whether these vehicles are parked facing forward or backward.
[0151] The installation may be equipped with one or more display screens, for example for information or advertising, particularly in the case of shopping center parking lots.
[0152] The installation can be equipped with ultrasonic vehicle presence detectors to identify free parking spaces.
[0153] Parking spaces can be reserved through apps in vehicles or mobile phones.
[0154] According to one aspect of the invention, the installation is equipped with a device for regulating the temperature of the tank, configured in particular to heat liquid in the tank. The device for regulating the temperature of the tank comprises, for example, heating provided by a self-regulating cable or an electrical resistor surrounding the tank. Thus, the installation is equipped with a temperature regulating device to prevent the water in the tank from freezing in winter and to allow optimal operation of the batteries required, in particular for lithium iron phosphate technology. The heating is provided by a self-regulating cable or a simple electrical resistor surrounding the tank. Alternatively, the electrical resistor may be of the immersion type, namely a resistor configured to be immersed in the liquid in the tank.The cooling of the water in the tank and therefore the batteries surrounding it is achieved by circulating the water over the solar panels during the night. Thanks to the invention, it is possible to heat or cool the batteries, and / or the inverter and / or the chargers, as needed. The invention notably makes it possible to obtain a fast charger with liquid cooling, without noise, for electric vehicles.
[0155] The invention allows in particular to have an "all in one" installation which is relatively easy to install, at a reasonable cost. The "all in one" aspect concerns in particular the integration of several, or even all, of these elements in the installation: solar panels, heat recovery from the air, battery cells, an inverter and / or a rectifier, a control box integrating management logic, the charger(s), rainwater recovery.
[0156] Using batteries to store electrical energy, produced by solar panels and / or recharged by the electricity network, makes it possible to install chargers (or charging stations), for example to recharge electric vehicles, free from constraints, for example regulatory constraints on usable electrical power.
[0157] If desired, the installation's batteries can be recharged, for example, at night by drawing electricity from the electricity grid, particularly from the urban electricity grid during off-peak hours when energy is less expensive and / or more abundant, or when the sky (during the day) is overcast during off-peak hours.
[0158] According to one aspect of the invention, the installation comprises a fluid circuit (in particular liquid), in particular recovered rainwater, for cooling and / or heating one or more charging stations, and / or one or more batteries, and / or one or more inverters of the installation. The fluid circuit is connected to the tank.
[0159] The invention is particularly advantageous due to the cooling function using liquid cooling (e.g. water), which generates much less noise than air cooling using noisy fans.
[0160] The invention thus makes it possible to have a particularly quiet installation, the cooling of the various components on the installation being essentially carried out by cooling liquid (for example water).
[0161] According to one aspect of the invention, a charging station for the vehicle is integrated within the pillar.
[0162] According to one aspect of the invention, the inverter is arranged on the top of the pillar.
[0163] According to one aspect of the invention, electrical charging power modules (linked to the inverter) are arranged on one face of the pillar, in particular one above the other on this face so as to form a row over the height of the pillar.
[0164] According to one aspect of the invention, an inverter is arranged above this row of electrical load power modules. These modules are, for example, four in number.
[0165] According to one aspect of the invention, the charging terminal is placed below this row of electric charging power modules, on the same face of the pillar.
[0166] According to one aspect of the invention, the charging station comprises a connection socket at the end of a cable allowing connection to an electric vehicle for charging.
[0167] According to one aspect of the invention, the charging station comprises an electronic controller configured to manage, for example, payment and / or display charging information.
[0168] According to one aspect of the invention, the pillar has, in cross-section, a rectangular outer circumference, with two long sides and two short sides. This circumference is notably different from a square.
[0169] According to one aspect of the invention, the electrical charging power modules are arranged on one face of the pillar, which corresponds to a short side of the rectangular circumference.
[0170] According to one aspect of the invention, battery cells are arranged on the two long sides of the rectangular periphery of the pillar.
[0171] According to one aspect of the invention, the short sides of the rectangular perimeter are devoid of battery cells.
[0172] According to one aspect of the invention, each pillar houses 2x160 cells, or 320 battery cells, for example a capacity of 320 kWh.
[0173] According to one aspect of the invention, the battery cells are arranged in several tiers, for example 20 tiers, along the height of the pillar.
[0174] For example, each floor has two rows of 8 cells lying down, or 16 cells per floor.
[0175] According to one aspect of the invention, the rectangular perimeter of the pillar has one side between 200 mm and 800 mm and another side between 200 mm and 1200 mm, having in particular dimensions of substantially 600 mm x 900 mm.
[0176] The invention allows an advantageous order of positioning of the different electrical elements.
[0177] Preferably, one or more electrical chargers are positioned at the bottom, on the pillar. Above the charger(s) are positioned batteries (or battery cells) and above the batteries is positioned an inverter. Thus the batteries are interposed (in the direction of height) between the charger(s) and the inverter.
[0178] Advantageously, these different electrical elements are arranged on a side face of the pillar.
[0179] According to one aspect of the invention, the batteries, or battery cells, are mounted in at least one rack, in particular a plurality of racks, in order in particular to allow mounting with electrical connections of the batteries on an external side of the pillar.
[0180] The rack(s) are, for example, arranged vertically.
[0181] For example, batteries are placed in a rack next to each other, and above this row is another row of batteries. This makes it possible to form several battery lines, or battery cells. The connectivity between battery cells is done at the bottom of the lines, on the outside of the pillar. Thus, the connection faces the outside of the pillar, away from the tank.
[0182] This allows you to connect the batteries, or battery cells, in series or parallel. The connection can be made at the end, once the cells are placed against the tank.
[0183] According to one aspect of the invention, the two parts of the roof, in particular arranged in a Y shape, are joined to the longitudinal beam in a watertight manner.
[0184] Thus there is no flow space between the roof parts and the longitudinal beam. We can say that the roof is closed.
[0185] The fact that the roof sections are tightly joined to the longitudinal beam prevents water from running down the pillar and bringing unwanted moisture to the electronic parts housed in the pillar.
[0186] Advantageously, the parts of the roof joined in a watertight manner with the longitudinal beam are configured to collect water, in particular rainwater, which can be collected towards a central tank, in particular housed in a pillar of the installation.
[0187] According to one aspect of the invention, the longitudinal beam is at least partly metallic.
[0188] According to one aspect of the invention, the longitudinal beam is made of steel for example.
[0189] According to one aspect of the invention, the pillar houses a central reservoir, in particular for the recovery of rainwater.
[0190] According to one aspect of the invention, the tank may have a volume greater than 150 liters, in particular between 300 and 600 liters, for example approximately 500 liters.
[0191] This tank may have a rectangular cross-section.
[0192] According to one aspect of the invention, the reservoir is adjacent to at least one row of battery cells, in particular a plurality of rows of battery cells arranged on faces of the pillar.
[0193] According to one aspect of the invention, the reservoir is interposed between two rows of battery cells arranged on opposite faces of the pillar.
[0194] According to one aspect of the invention, the reservoir can have a relatively large volume, thanks to the cross-section of the pillar.
[0195] According to one aspect of the invention, a longitudinal beam of the roof has windows to allow air from the roof to be collected into the main duct of the longitudinal beam.
[0196] According to one aspect of the invention, the discharge channel of the transverse beam is thus easily connected to the main duct of the longitudinal beam.
[0197] According to one aspect of the invention, the fan for circulating air (forced circulation) in the main duct of the longitudinal beam to evacuate hot air heated by the solar panels can be relatively silent. This fan only operates when it is necessary to cool the solar panels (therefore mainly during the day, and not at night).
[0198] According to one aspect of the invention, a tubing is configured to conduct the water collected in the gutter to the reservoir within the pillar.
[0199] According to one aspect of the invention, the tubing may be on the passage of the air recovered in the main duct of the longitudinal beam.
[0200] The tubing is, for example, placed between the transverse beam at its outlet and a window in the longitudinal beam.
[0201] According to one aspect of the invention, a water pump is configured to circulate the water taken from the reservoir to take it to the solar panel(s) and to cause the water to flow over the solar panels (in particular by generating a water curtain or sheet of water, preferably without spraying or water jet), in particular at night to cool the water in contact with the solar panels.
[0202] According to one aspect of the invention, the cooled water is returned to the tank so as to cool the battery cells which are likely to heat up when they are recharged, for example by an electrical network, for example during the night (when the solar panels are off).
[0203] According to one aspect of the invention, water is deposited on the solar panel through a slot to distribute the water in the form of a curtain or sheet of water, which then flows uniformly over the surface of the solar panel to be cooled, in particular during the night in cool temperatures.
[0204] The invention also relates to a method for cooling battery cells using a water circuit configured to allow the circulation of water, in a aforementioned installation, comprising the following steps: flowing water over one or more solar panels, in particular during the night, allowing the water to be cooled, recovering this cooled water to cool battery cells of the installation.
[0205] The invention is advantageous in the sense that it allows the solar panels to be used when they are sufficiently cold, as a cooler for the liquid circulating towards the batteries, chargers, etc.
[0206] According to one aspect of the invention, the pillar comprises cladding configured to close the junction between the longitudinal beam and the transverse beam.
[0207] The invention also relates to a set of two installations arranged side by side.
[0208] According to one aspect of the invention, the battery cells are arranged lying down. Advantageously, the terminals of the cells are on the same face of the pillar. This can allow easy interconnection and increased accessibility for assembly and maintenance. This also allows contact of the battery housing against the walls of the liquid reservoir which is used for heating.
[0209] This makes it easier to connect the battery cells and takes up less space.
[0210] Preferably, the roof is fixed. There is no system to move the solar panels, for example, to follow the path of the sun.
[0211] The invention also relates to a pillar configured to be assembled in a aforementioned installation, in particular allowing heating of batteries, in particular for lithium batteries.
[0212] The invention also relates to a roof or a roof portion configured to be assembled in a aforementioned installation.
[0213] According to one aspect of the invention, the batteries are cooled or heated directly or indirectly by the liquid in the reservoir.
[0214] According to one aspect of the invention, the charging station is powered by the batteries, or the electrical network or both at the same time.
[0215] According to one aspect of the invention, the charging station corresponds to a fast charger associated with an AC / DC module (powered by the network or an inverter) or a DC / DC module (powered by the batteries) or AC / DC and DC / DC (Network / Inverter and Batteries).
[0216] According to one aspect of the invention, the charger is cooled directly or indirectly with water from a reservoir of the installation.
[0217] According to one aspect of the invention, the coolant of the charger(s) is the same as or different from that of the reservoir. In the case where the liquids are different, a secondary cooling circuit using a second heat transfer fluid is provided between the liquid of the reservoir and the surface of the charger.
[0218] According to one aspect of the invention, heat recovery is carried out with an air flow in the direction of the width of the panels, perpendicular to the direction of the electric current passing through the photovoltaic cells of the same panel in order to avoid temperature gradients between photovoltaic cells of the panel.
[0219] The invention provides the possibility of using Lithium or Sodium batteries without changing other electrical components, in particular the inverter.
[0220] According to one aspect of the invention, the installation is provided with permanent thermal cameras.
[0221] The invention also relates to an energy production installation configured to be installed in particular on the ground, in particular on a parking lot, and comprising a central pillar configured to carry at least one roof provided with at least one solar panel, the roof comprising at least one air circulation channel extending at least partially under the solar panel to allow the air in the channel to be heated by the heat released by the solar panel, and the roof is configured so that the heat recovery is done with an air flow in the direction of the width of the panels, perpendicular to the direction of the electric current passing through photovoltaic cells of the same panel.
[0222] The invention also relates to an energy production installation configured to be installed in particular on the ground, in particular on a parking lot, and comprising a central pillar in particular configured to carry at least one roof provided with at least one solar panel, and the pillar houses a central reservoir, in particular for the recovery of rainwater, the reservoir being able in particular to have a volume greater than 150 liters, in particular between 300 and 600 liters, for example approximately 500 liters, and the reservoir is adjacent to at least one row of battery cells, in particular a plurality of rows of battery cells arranged on faces of the pillar, and the reservoir is in particular interposed between two rows of battery cells arranged on opposite faces of the pillar.
[0223] The invention also relates to an energy production installation configured to be installed in particular on the ground, in particular on a parking lot, and comprising a central pillar configured to support at least one roof provided with at least one solar panel, and the roof comprises two parts of the roof, in particular arranged in a Y shape, which are joined with the longitudinal beam, in a sealed manner.
[0224] The invention also relates to an energy production installation configured to be installed in particular on the ground, in particular on a parking lot, and comprising a central pillar in particular configured to support at least one roof provided with at least one solar panel, and the pillar houses a central reservoir, in particular for the recovery of rainwater, and the installation comprises data center modules, and comprises a heat transfer fluid circuit configured to cool the data center module(s).
[0225] According to one aspect of the invention, the installation comprises chargers configured to recharge electric or hybrid vehicles.
[0226] According to one aspect of the invention, the charger comprises a housing provided with fluid connections making it possible to connect a heat transfer fluid circuit to the housing to pass the heat transfer fluid inside the housing, in particular to cool the charger.
[0227] According to another aspect of the invention, the installation comprises data center modules, also called Data Center in English.
[0228] In particular, data center modules include one or more computer servers.
[0229] According to one aspect of the invention, the computer server(s) are configured to be electrically connected to the battery module(s) of the installation.
[0230] In other words, it is possible to use the batteries of the installation, which are in particular recharged by the solar panel(s), for the electrical supply of the data center modules arranged on the installation according to the invention.
[0231] The installation may be without an electric charger for vehicle charging and the installation includes, instead of these chargers, data center modules.
[0232] Data center modules are configured to perform computations, preferably without data storage.
[0233] In other words, the calculations are performed without the need for data storage in computer servers on this facility.
[0234] According to one aspect of the invention, the data center modules are connected for high-speed data communications with remote data centers (particularly cloud computing).
[0235] The computer servers located on the installation are configured to perform intensive calculations of artificial intelligence models based in particular on graphics cards (GPU), without excluding the use of microprocessors (CPU) if required.
[0236] Computer servers, when operating, release a substantial amount of heat.
[0237] According to one aspect of the invention, the installation comprises a heat transfer fluid circuit configured to cool the data center module(s).
[0238] According to one aspect of the invention, the data center module comprises a housing and the heat transfer fluid circuit is connected to this housing so that heat transfer fluid can circulate in the housing to cool the computer server(s).
[0239] Thus, the heat transfer fluid (for example, glycol water) leaves the data center module housing at a higher temperature than when it enters.
[0240] Furthermore, since the electricity used to power computer servers comes from solar energy from solar panels, the invention helps reduce the CO2 footprint in the operation of computer servers.
[0241] The invention thus makes it possible to take advantage of available locations, for example on installations placed in vehicle parking lots, to host data center modules which can then operate using electricity produced by solar panels and be cooled, for example, by recovered rainwater.
[0242] The invention, thanks to the recovery of rainwater for cooling, eliminates the need to use water from the city network, for example. This can allow for better water management. High city water consumption has often been the reason for abandoning data center projects.
[0243] The present invention also helps reduce installation costs for data center modules by sharing the location with other features of the parking facility.
[0244] According to one aspect of the invention, the heat transfer fluid circuit is configured to transport heat from the data center modules to indirectly heat the batteries.
[0245] According to one aspect of the invention, the heat transfer fluid circuit is configured to heat the water in the tank which is in heat exchange with the batteries, particularly in winter.
[0246] So the heat produced by the data center modules is used to heat the fluid (water) in the fluid circuit which, in turn, will heat the water in a central tank, thus heating the batteries which are placed adjacent to the central tank.
[0247] According to one aspect of the invention, the installation comprises an additional liquid reservoir, in particular for receiving recovered rainwater.
[0248] According to one aspect of the invention, the additional tank is filled with water.
[0249] According to one aspect of the invention, the water in the tanks is renewed at night, by being circulated on the solar panels in particular by a pump.
[0250] According to one aspect of the invention, the additional reservoir is arranged on one side of the pillar, in particular on one face of the pillar, being in particular adjacent to the central reservoir.
[0251] According to one aspect of the invention, the tanks are configured to be supplied with water collected using one or more gutters from the roof.
[0252] According to one aspect of the invention, a conduit is advantageously provided to conduct the water flowing over the solar panels and collected by the gutter to the water tanks.
[0253] According to one aspect of the invention, the heat transfer fluid circuit is a closed circuit which comprises portions, for example in a coil, which are configured to be immersed in the water of the central tank and portions, for example in a coil, which are configured to be immersed in the additional tank.
[0254] The heat transfer fluid circuit is equipped with a pump to circulate the fluid in the circuit.
[0255] The heat transfer fluid circuit comprises at least one 3-way valve configured to manage the circulation of heat transfer fluid, selectively, either towards the central tank or towards the additional tank.
[0256] When the central tank does not need to be heated (e.g. in summer mode), the 3-way valve is configured to allow the circulation of heat transfer fluid in the portion of the heat transfer fluid circuit to the additional tank so that the heat transported by this heat transfer fluid circuit is recovered by the water in the additional tank, and not in the water in the central tank (heating of the batteries is not desirable in summer).
[0257] When the central tank needs to be heated (for example in winter mode), the 3-way valve is configured to allow the circulation of heat transfer fluid in the portion of the heat transfer fluid circuit towards the central tank so that the heat transported by this heat transfer fluid circuit is recovered by the water in the central tank, and not in the water in the additional tank.
[0258] The central tank with water heated by the heat transfer fluid circuit allows the walls to be heated, which in turn heat the batteries.
[0259] The heat generated by the computing modules, like the charging modules, could be recovered through a heat exchanger to be used for heating buildings.

[0282] The features, variants and different embodiments of the invention may be combined with each other in various combinations, provided that they are not incompatible or mutually exclusive. In particular, variants of the invention may be conceived comprising only a selection of features described below in isolation from the other features described, if this selection of features is sufficient to confer a technical advantage and / or to differentiate the invention from the prior art.
[0283] Figures 1 and 2 show an assembly 100 comprising a plurality of energy production installations 1 according to an exemplary embodiment of the invention, these installations 1 being arranged side by side.
[0284] Installations 1 are placed in a parking lot, for example, of a shopping center, a train station, an airport or an industrial complex.
[0285] Each energy production installation 1 is configured to be installed on a ground S, and comprises a central pillar 2 configured to support a roof 3 provided with solar panels 4.
[0286] The roof 3 has air circulation channels 7 extending under the solar panels 4 to allow the air in each channel 7 to be heated by the heat given off by the solar panels 4, as illustrated in 7.
[0287] Each roof 3 is made of two parts 8 and 9 arranged on either side of the central pillar 2.
[0288] The two parts 8 and 9 of roof 3 are parallel and are in the extension of each other.
[0289] The two roof parts 8 and 9 extend along a common PC plane inclined relative to pillar 2.
[0290] The common plane PC is inclined relative to pillar 2 at an angle AG of between 70° and 90°, in particular at an angle of approximately 85°.
[0291] The two parts 8 and 9 of the roof are spaced from each other by an opening 10.
[0292] The top of pillar 2 extends through this opening 10.
[0293] This opening 10 between the two roof parts also allows the wind to flow into this opening 10 so as to break the forces that a strong wind could exert on the installation.
[0294] The two parts 8 and 9 of roof 3 have an identical surface area and have a rectangular perimeter.
[0295] Each roof 3 comprises at least one box 12 configured to support the solar panels 4. The width of the box 12 as well as that of the solar panels 4 are adjustable (for example by being modular) to adapt to the standards of widths of parking spaces, which can vary from one region to another.
[0296] Each part 8, 9 of the roof has its own box 12 on which the solar panels 4 are mounted.
[0297] The box 12 comprises metal supports 14 on which the solar panels are placed. For example, the box 12 comprises supports, in particular metal supports 14, on which the solar panels are placed on the upper part and a panel 15 made of high-pressure laminate, or other bio-sourced material, on the lower part, as illustrated in the.
[0298] These supports 14 are formed in particular by a peripheral edge of the box 12.
[0299] The supports 14 can also be formed by transverse bars 16 arranged at different locations of the box 12.
[0300] The transverse support bars 16 are rectilinear and arranged in a parallel and equidistant manner from each other.
[0301] The opening 10 between the two roof parts 8, 9 is formed between two parallel rectilinear edges 18, 19 opposite these roof parts 9, 9, and the transverse bars 16 are parallel to these edges, as illustrated in the.
[0302] The solar panels 4 thus rest on the peripheral edge and on the transverse bars 16 which are then located under the solar panels.
[0303] Each box 12 has air inlet slots 20 configured to allow air to flow into the box 12 and to allow the air to be heated by the solar panels 4 that close the box 12. A sufficiently fine mesh grille may be arranged over the inlet slots 20 to filter out any external objects or bodies. External crossbars supporting the boxes 12 are configured to protect the air inlet slots from rainwater infiltration.
[0304] Each air inlet slot 20 extends along an edge 21 of the box 12.
[0305] Each box 12 has pairs of air inlet slots 20 arranged along two opposite sides 21 of the box 12. For the end panels, an additional slot could be added. The slots may be of the same dimensions or different from each other.
[0306] The box 12 comprises an air collection slot 22 configured to allow the evacuation of air coming from the inlet slots 20 and having circulated in the box 12 in summer heated by the solar panels 4, as illustrated in the.
[0307] The air inlet slot 20 has an elongated shape.
[0308] The air collection slot 22 has an elongated shape.
[0309] The air inlet slots 20 are aligned along each side 21 of the box 12. Other secondary inlet slots may be placed perpendicular to the collection slots.
[0310] The air inlet slots 20 and the collection slots 22 are parallel to each other, and are perpendicular to the transverse support bars 16 for the solar panels.
[0311] The collection slots 22 are located equidistant from the air inlet slots 20.
[0312] The installation 1 further comprises a longitudinal beam 25 connecting to the vertical central pillar 2 and the longitudinal beam 25 extends into the space / opening 10 between the two parts 8, 9 of the roof, parallel to the two edges 21 of the roof.
[0313] In the set 100 of several installations 1, the longitudinal beams 25 are placed one in the extension of the other.
[0314] It is thus possible to recover heated air at the end of this succession of longitudinal beams 25.
[0315] Installation 1 also includes a transverse beam 26 connecting to the central pillar 2 and supporting the two roof parts 8, 9.
[0316] Installation 1 thus comprises the central pillar 2 which carries the longitudinal beam 25 and the transverse beam 26.
[0317] It is thus possible to form installation 1 with a total number of pillars / beams equal to three.
[0318] The longitudinal beam 25 and the transverse beam 26 intersect at right angles.
[0319] The air exhaust / collection slot 22 in the roof box 12 is open to the transverse beam 26 which is hollow.
[0320] The beams 25 and 26 are hollow as is the central pillar 2, so that the air having circulated in the box 12 and which is heated by the solar panels 4 circulates through the air evacuation slot 22 towards the transverse beam 26.
[0321] Each transverse beam 26 is hollow and thus forms, in whole or in part, a channel for discharging the heated air. Each transverse beam 26 may be equipped with a fan 28 (see) for discharging the air towards a main duct, in the longitudinal beam 25.
[0322] This discharge channel in the transverse beam 26 extends into the longitudinal beam 25.
[0323] The longitudinal beam 25 is configured to evacuate the air circulating therein to an air heat recovery system. According to one aspect of the invention, this system comprises, for example, a heat pump placed, for example, in a building to heat it.
[0324] The fan 28 is electric, and configured to draw air towards the air circulation channel in the longitudinal beam 25.
[0325] This air suction creates the air flow from the air inlet slots 20 on the roof box 12 to the channel of the longitudinal beam 25.
[0326] The fan 28 is placed within the longitudinal beam 25. Other fans can also be placed on each transverse beam 26.
[0327] The pillar 2 and / or the longitudinal beam 25 and / or the transverse beam 26 are each made with an assembly of plates based on bio-sourced materials, wood or others such as high-pressure laminates of paper and resins intended for exterior cladding.
[0328] The assembly of plates 30 forms an external envelope of the pillar 2 and / or of the longitudinal beam 25 and / or of the transverse beam 26.
[0329] As can be seen in the, the assembly 30 further comprises wooden beam elements 31, arranged in parallel, at the four corners of the rectangular perimeter, and between which the plates are arranged. The beam elements 31 can also be made of steel, in particular for the central pillar 2 where the heat exchange is not critical.
[0330] For the central pillar 2, these beam elements 31 measure, for example, 3 to 6 meters or more.
[0331] In the interior space of this envelope, honeycomb structures 32, made of plastic material, are arranged.
[0332] Each honeycomb structure 32 has a rectangular or square outline, and has a grid or honeycomb shape.
[0333] The honeycomb structure 32 occupies an entire interior section of the pillar 2 or the beam 25, 26.
[0334] Several honeycomb structures 32 are provided in the hollow pillar 2 and / or the hollow beam 25, 26, at a distance from each other.
[0335] The honeycomb structures 32 may be made of reinforced plastic, in particular with glass fibers.
[0336] The assembly of wooden plates 30 is reinforced by reinforcements 33, in particular metal reinforcements 33.
[0337] The reinforcements 33 are on an external face of the plate assembly 30. Alternatively, the reinforcements 33 may be on the internal face, in particular for aesthetic or functional reasons when thermal conduction is not affected.
[0338] The metal reinforcements 33 may be V-shaped or cross-shaped, and are configured to mechanically reinforce the pillar 2 and / or the longitudinal beam 25 and / or the transverse beam 26.
[0339] The metal reinforcements 33 can also be used to interconnect the longitudinal beam 25 and the transverse beam 26 to the central pillar 2.
[0340] The installation 1 comprises an electric charging station 35 or several electric charging stations 35 configured for charging one or several electric vehicles V parked in the spaces Pk covered by the installation 1, as illustrated in a.
[0341] Charging station 35 has a charging socket to be connected to an electric vehicle V.
[0342] An electrical circuit connects the solar panels 4 to an inverter 37 capable of producing electricity compatible with charging for an electric vehicle.
[0343] The inverter 37 is arranged on the installation 1, being attached to the central pillar 2 of this installation (see).
[0344] The inverter 37 can be placed at a height sufficient to be taller than the average height of a person.
[0345] The inverter 37 is placed, for example, 2 meters or more from the ground.
[0346] Charging station 35 is placed on a base 39 of installation 1, against pillar 2.
[0347] Roof 3 is configured to cover one or four Pk parking spaces for motor vehicles.
[0348] Each roof portion 8, 9 is configured to receive a plurality of solar panels, for example 4 or 5 solar panels.
[0349] Roof 3 has a total length of at least 2 meters, measured parallel to longitudinal beam 25.
[0350] Each roof 3 has a dimension measured along the transverse beam 26 of at least 4 meters, or 5 meters.
[0351] Each solar panel 4 is configured to have a power density of at least 400 Wp (Watt-peak) per panel, chosen at 700 Wp nominal for example.
[0352] The roof 3 is inclined and has a lower edge 41 which is closest to the ground when the installation 1 is mounted. This lower edge 41 is at a height of approximately 4.2 meters from the ground.
[0353] The central pillar 2 is hollow and defines a housing 42 for receiving several battery modules 43.
[0354] Each battery module 43 is connected to the inverter 37, itself connected to the solar panels 4 which are then used for the electrical recharging of the battery module 43.
[0355] The 43 battery module can be sodium technology.
[0356] The honeycomb structures 32 are configured to define the different housings 42 receiving the battery modules 43.
[0357] The central pillar 2 includes housings 42 on several levels to receive the battery modules 43, as can be seen in the.
[0358] The central pillar 2 is fixed to the base 39.
[0359] Base 39 is configured to be buried in the ground and is of relatively low height, this height being notably less than 600 mm.
[0360] Installation 1 includes a buried anchoring system 45 configured to keep the base 39 of the central pillar 2 anchored in the ground, as illustrated in the.
[0361] The anchoring device 45 comprises buried cables 46, each with one end secured to the base 39 of the installation and another end attached to a dowel 47 configured to be fixed deep in the ground.
[0362] There are four cables 46. In particular, the anchor cables also serve as an electrical ground conduit for the installation. The anchor cables 46 of one of the installations could be several meters longer than the others to serve as a lightning rod. These particular anchors are connected by wiring to a mast on the roof 3 to channel lightning.
[0363] The base 39 of the installation projects a certain height from the ground when the base 39 is fixed to the ground.
[0364] Base 39 presents, on this emerged height, a shape chosen to serve as a stop for a vehicle wheel.
[0365] Thus when a vehicle approaches the central pillar 2 to park under the roof 3, the wheel of the car closest to the central pillar 2 comes up against the base 39 so as to signal to the driver that he cannot approach any closer to the central pillar 2.
[0366] This provides reliable security to prevent a vehicle from hitting the central pillar 2 of the installation.
[0367] The base 39 has a cross-shaped edge 48 configured to serve as a stop for a vehicle wheel.
[0368] Installation 1 uses sustainable materials such as wood and / or metal.
[0369] According to one aspect of the invention, the wooden panels under the solar panels and which form the box 12 are protected by a metal shield to avoid thermal stress on these wooden panels.
[0370] Installation 1 includes a hydraulic type solar panel cleaning system 50, as illustrated in the.
[0371] The cleaning system 50 comprises a member 51 for projecting liquid onto the solar panels 4.
[0372] This liquid projection member 51 comprises a tube 53 placed along an upper edge 54 of the roof 3.
[0373] The tube 53 is provided with a longitudinal slot 55, along this upper edge 54 of the roof 3.
[0374] A liquid is projected through this slot 55, under moderate pressure, in order to clean the surface of the solar panels 4, without damaging them.
[0375] The tube 53 is connected to a water reserve 60, here a rainwater recovery reserve.
[0376] The connection between the reserve 60 and the projection tubes 53 is made by a conduit 57 housed in the central pillar 2, visible in figures 4 and 9.
[0377] The rigid conduit 57 is made of reinforced plastic, for example reinforced with glass fibers. The conduit 57 can also serve as reinforcement for the central pillar 2 by connecting to the wooden beams through honeycomb composite plates.
[0378] Conduit 57 extends from the bottom to the top of the central pillar 2.
[0379] For example, the conduit 57 has a height of at least 80% or 90% of the total height of the central pillar 2. Advantageously, the volume of water in the conduit does not exceed 90% in order to contain the volume of frozen water. The choice of composite materials for the conduit or reservoir must enable it to withstand freezing stresses while contributing to the rigidity of the structure of the main pillar.
[0380] Several pipes may be provided to connect the water projection tube 53 to this vertical conduit 57.
[0381] These pipes are arranged in the boxes 12.
[0382] The cleaning system 50 may comprise two water projection tubes, one for one of the parts 8 of the roof 3 and the other for the other part 9 of the roof 3.
[0383] The installation 1 comprises a water pump 59 configured to pump water from the reserve 60 and direct it to the cleaning system 50.
[0384] Installation 1 comprises a gutter 68 configured to collect rainwater flowing over the roof 3, and to direct the collected rainwater into the central foot reserve.
[0385] The pump 59 for pumping water is of the electric type. It can be activated by a dust sensor and / or at predefined time intervals, or during the night in summer to cool the water in the tank heated by the heat released by the batteries.
[0386] The recovered water can be filtered before reaching the tank 60. Advantageously, the water level in the tank 60 is controlled by a distance sensor located on a main control box installed at the top of the central pillar.
[0387] The installation 1 comprises one or more thermal control cameras 61, in particular fixed to the top of the central pillar 2, and configured to measure the temperature on the surface of the solar panels 4.
[0388] This thermal camera 61 is fixedly mounted on the central pillar 2 or mounted in a mobile manner, for example to allow it to rotate and be oriented towards the solar panels. In particular, the thermal cameras are fixedly mounted on the central pillar 2 or the camera is mounted in a mobile manner, in particular when it is a single camera.
[0389] The 61 thermal camera allows continuous monitoring of the potential appearance of hot spots on the surface of solar panels.
[0390] Hot spots can pose a danger to the installation 1. The thermal camera 61 can possibly detect the presence of animals (birds, rodents, insects) that can damage the installation through the deposit of waste, nests or by gnawing cables. The detection will be transmitted to an electronic module that triggers, for example, an animal-repellent sound. It can also help to alert on a malicious human action (theft, breakage). Temperature sensors are possibly used to monitor the temperature in places where it is required.
[0391] The installation may include a control unit configured to receive information from the thermal camera 61 and trigger an alert when a hot spot has been detected on one of the solar panels.
[0392] The roof 3 includes a fire alert system 65 configured to generate an alert in the event of a fire or abnormal temperature on the roof 3.
[0393] The fire alarm system 65 includes wires 66 which snake under the solar panels 4.
[0394] These 66 wires are configured to melt in case of high temperature.
[0395] Melting the wire creates a short circuit, which triggers an alert. The wires can also be connected to the control box to provide pre-alerts (for example, by email, telephone, etc.).
[0396] The wires 66 of the fire alarm system are placed in the path of the air flow under the solar panels so that its wires generate turbulence in this air flow promoting a better heat exchange between the air and the solar panels. The wires 66 are notably retained by devices on the lower part of the boxes in order to remain at a controlled and sufficient distance from the solar panels.
[0397] It is possible to provide disturbance elements other than these wires 66 or in addition to these wires.
[0398] When the ambient temperature is low or negative (less than 5°C for example), the water in the tank 60 can be electrically heated by a cable 190 illustrated in the, or a heating strip or by other means to prevent the water from freezing while radiating heat to heat the batteries and thus increase their performance and extend their lifespan. In summer, the water in the tank 60 heated during the day by the batteries is cooled at night by running it over the solar panels while cleaning them in the process, knowing that the dust level is generally higher in summer. The cable 190 forms a spiral around the conduit 57 housed in the central pillar 2.
[0399] In another embodiment of the invention illustrated in , the two parts of the roof 200 and 201 extend in respective planes which are intersecting, forming, in profile, a Y with the central pillar 2. Generally speaking, the arrangement of the roof parts can be adapted according to environmental constraints and / or the need for water recovery.
[0400] Fast charging stations with power exceeding 100kW could be placed away from the mast or central fold 2.
[0401] In one example, the installation containing lithium or sodium batteries whose capacity could vary from 5kWh to more than 100 kWh allows the storage of electricity produced by solar panels or serves as a means of absorbing surplus electricity in the event of grid saturation during excess wind and photovoltaic production. This electricity could be reinjected into the grid when demand requires it.
[0402] In a variant illustrated in, the sections of the slots 22 can vary for better uniformity of the air in the box 12. In particular, the further one is from the pillar, the wider the collection slot 22 is to compensate for pressure losses.
[0403] Figures 15 and 16 show an assembly 250 comprising two energy production installations 251 according to an exemplary embodiment of the invention, these installations 1 being arranged side by side.
[0404] Each energy production installation 251 comprises two roof parts 200 and 201 extending in respective planes which are intersecting, forming, in profile, a Y with the central pillar 2.
[0405] For each energy production installation 251, a charging station 254 for the vehicle is integrated within pillar 2.
[0406] Inverter 37 is located on top of pillar 2.
[0407] Electrical charging power modules 255 (linked to the inverter) are arranged on a face 256 of the pillar 2, in particular one above the other on this face so as to form a row over the height of the pillar 2, as can be seen in the.
[0408] The inverter 37 is arranged above this row of electrical load power modules 255. These modules 255 are, for example, four in number.
[0409] The charging station 254 is placed below this row of electric charging power modules, on the same face 256 of the pillar 2.
[0410] The charging station 254 has a connection socket 258 at the end of a cable allowing connection to an electric vehicle for charging.
[0411] The charging station 254 comprises an electronic controller 259 configured to manage, for example, payment and / or display charging information.
[0412] Pillar 2 has, in cross-section, a rectangular outer perimeter, with two long sides and two short sides. This perimeter is notably different from a square.
[0413] The electrical charging power modules 255 are arranged on one face of the pillar, which corresponds to a short side of the rectangular periphery 260, as can be seen in the.
[0414] Battery cells 261 are arranged on the two long sides of the rectangular perimeter 260 of the pillar 2.
[0415] The short sides of the rectangular 260 surround are devoid of battery cells.
[0416] Each pillar houses 2x160 261 cells, or 320 battery cells, for example a capacity of 320 kWh.
[0417] The 261 battery cells are arranged in several tiers, for example 20 tiers, along the height of the pillar.
[0418] For example, each floor has two rows of 8 cells lying down, or 16 cells per floor.
[0419] For example, the rectangular perimeter 260 of the pillar is 600 mm x 900 mm.
[0420] According to one aspect of the invention, the two parts of the roof 200 and 201, in particular arranged in a Y shape, are joined to the longitudinal beam 264, in a sealed manner.
[0421] The fact that the roof parts 200 and 201 are joined in a watertight manner with the longitudinal beam 264 prevents water from flowing along the pillar 2 and bringing unwanted humidity onto the electronic parts housed in the pillar 2.
[0422] The longitudinal beam 264 is made of steel for example.
[0423] Pillar 2 houses a central tank 270, for the recovery of rainwater.
[0424] The tank 270 can have a volume between 300 and 600 liters, for example approximately 500 liters.
[0425] This tank 270 may have a rectangular cross-section.
[0426] The reservoir 270 is adjacent to rows of battery cells 261 arranged on faces of the pillar 2, as illustrated in the.
[0427] The tank 270 is interposed between two rows of battery cells 261 arranged on opposite faces of the pillar 2.
[0428] Tank 270 can have a relatively large volume, thanks to the cross-section of pillar 2.
[0429] The longitudinal beam 264 has windows 272 to allow air from the roof to be collected into the main duct 275 of the longitudinal beam 264, as illustrated in the.
[0430] The discharge channel 276 of the transverse beam 277 is thus easily connected to the main conduit 275 of the longitudinal beam 264.
[0431] A tubing 280 is configured to conduct the water collected in the gutter to the reservoir 270 within the pillar.
[0432] The tubing 280 is for example placed between the transverse beam 277 at the outlet thereof, and a window 272 of the longitudinal beam 264.
[0433] A water pump is configured to circulate the water taken from the reservoir 270 to take it to the solar panel(s) with photovoltaic cells, and to cause the water to flow over the solar panels (in particular by generating a water curtain or sheet of water, preferably without spraying or water jet), in particular at night to cool the water in contact with the solar panels.
[0434] The cooled water is returned to the tank 270 so as to cool the battery cells which are likely to heat up during their recharging, for example by an electrical network, for example during the night (when the solar panels are off). This forms a fluid circuit 279 (in particular liquid), here recovered rainwater, to cool and / or heat one or more charging stations, and / or one or more batteries, and / or one or more inverters of the installation. The pipes 280 belong to this fluid circuit 279.
[0435] Water is deposited on the solar panel through a slot to distribute the water in the form of a curtain or sheet of water, which then flows evenly over the surface of the solar panel to be cooled, especially during the night in cool temperatures.
[0436] Pillar 2 includes a cladding 288 configured to close the junction between the longitudinal beam and the transverse beam.
[0437] The batteries are cooled or heated directly or indirectly by the liquid in the reservoir 270.
[0438] The charging station is powered by batteries, the electricity grid, or both.
[0439] The charging station corresponds to a fast charger associated with an AC / DC module (powered by the network or an inverter) or a DC / DC module (powered by the batteries) or AC / DC and DC / DC (Network / Inverter and Batteries).
[0440] The charger is cooled directly or indirectly with water from the tank 270.
[0441] The coolant of the chargers is the same or different from that of the tank 270. In the case where the liquids are different, a secondary cooling circuit using a second heat transfer fluid is created between the liquid of the tank and the surface of the charger.
[0442] Heat recovery is achieved with air flow in the width direction of the panels, perpendicular to the direction of the electric current.
[0443] The invention provides the possibility of using Lithium or Sodium batteries without changing the inverter.
[0444] The facility is equipped with permanent thermal cameras.
[0445] In the exemplary embodiment of the invention described in figures 20 and 21, the installation 1 comprises data center modules 300, also called Data Center in English.
[0446] The 300 data center modules include one or more computer servers.
[0447] The computer servers are configured to be electrically connected to the 302 batteries in Facility 1.
[0448] In other words, it is possible to use the batteries 302 of the installation 1 which are in particular recharged by the solar panel(s), for the electrical power supply of the data center modules 300 arranged on the installation 1 according to the invention.
[0449] Installation 1 may be without an electric charger for vehicle charging and installation 1 includes, instead of these chargers, data center modules 300 (Data Center).
[0450] The 300 data center modules are configured to perform computing with or without data storage.
[0451] In other words, the calculations are carried out without necessarily needing to store the data in the computer servers on this installation.
[0452] According to one aspect of the invention, the data center modules 300 are connected for high-speed data communications with remote data centers (particularly cloud computing).
[0453] The computer servers located on installation 1 are configured in particular to perform artificial intelligence model calculations.
[0454] Computer servers, when operating, release a substantial amount of heat.
[0455] The installation 1 comprises a heat transfer fluid circuit 310 configured to cool the data center module(s) 300.
[0456] The data center module 300 comprises a housing 303 and the heat transfer fluid circuit 310 is connected to this housing 303 so that heat transfer fluid can circulate in the housing 303 to cool the computer server(s).
[0457] The housing 308 is provided with fluid connections 322 for connecting a heat transfer fluid circuit to the housing to pass the heat transfer fluid inside the housing.
[0458] The heat transfer fluid circuit 310 has branches for bringing the fluid into the various data center modules 300.
[0459] Thus, the heat transfer liquid (for example glycolated water) leaving the housing 303 of the data center module has a higher temperature than at its inlet.
[0460] The heat transfer fluid circuit 310 is configured to transport heat from the data center modules 300 to indirectly heat the batteries 302.
[0461] The heat transfer fluid circuit 310 is configured to heat the water in the tank which is in heat exchange with the batteries 302.
[0462] Thus the heat produced by the data center modules 300 is used to heat the fluid (water) in the fluid circuit which, in turn, will heat the water in a central tank 307, thus making it possible to heat the batteries 302 which are placed adjacent to the central tank 307.
[0463] Installation 1 includes an additional liquid tank 308 to receive recovered rainwater.
[0464] The additional reservoir 308 is arranged on one side of the pillar, in particular on one face of the pillar, being in particular adjacent to the central reservoir 307.
[0465] Tanks 307 and 308 are configured to be supplied with water collected using one or more gutters from the roof.
[0466] A conduit is advantageously provided to conduct the water flowing over the solar panels and collected by the gutter to the water tanks.
[0467] The heat transfer fluid circuit 310 is a closed circuit which comprises portions 317, for example in a coil, which are configured to be immersed in the water of the central tank 307 and portions 318, for example in a coil, which are configured to be immersed in the additional tank 308.
[0468] The heat transfer fluid circuit 310 is provided with a pump for circulating the fluid in the circuit.
[0469] The heat transfer fluid circuit 310 comprises at least one 3-way valve 316 configured to manage the circulation of heat transfer fluid, selectively, either towards the central tank 307, or towards the additional tank 308.
[0470] When the central tank 307 does not need to be heated (for example in summer mode), the 3-way valve is configured to allow the circulation of heat transfer fluid in the portion of the heat transfer fluid circuit 310 towards the additional tank 308 so that the heat transported by this heat transfer fluid circuit 310 is recovered by the water in the additional tank 308, and not in the water of the central tank 307 (heating of the batteries 302 not being desirable in summer).
[0471] When the central tank 307 needs to be heated (for example in winter mode), the 3-way valve is configured to allow the circulation of heat transfer fluid in the portion of the heat transfer fluid circuit 310 towards the central tank 307 so that the heat transported by this heat transfer fluid circuit 310 is recovered by the water in the central tank 307, and not in the water of the additional tank 308.
[0472] The central tank 307 with water heated by the heat transfer fluid circuit 310 makes it possible to heat the walls which, in turn, will heat the batteries 302.
