[0001] Cross-referencing of related patent applications This application claims the benefit and priority of U.S. Provisional Application No. 63 / 597,588, filed November 9, 2023, and U.S. Provisional Application No. 63 / 622,005, filed January 17, 2024, the entire disclosure of which is incorporated herein by reference. Background Technology

[0002] This disclosure generally relates to modular buildings, such as mobile buildings and other mobile structures. Some of these modular buildings are formed from storage or shipping containers, and / or otherwise constructed to standardized shipping container dimensions. Such modular buildings are typically deployed in environments where grid power is not readily available (e.g., construction sites, mining sites, oil drilling platforms). There is a pressing need to provide an easily deployable alternative or supplemental power source for such modular buildings. Summary of the Invention

[0003] Embodiments of this disclosure include a solar energy device for mobile buildings. The solar energy device includes a housing and a photovoltaic panel array. A convexity of the array along the longitudinal direction of the solar energy device defines an open space below the array, and the housing is disposed within the open space.

[0004] In some embodiments, the solar energy device further includes a base frame member extending longitudinally along the solar energy device. The base frame member is substantially straight, and the open space is located between the base frame member and the photovoltaic panel array. The convexity of the panels allows the longitudinal ends of the panels to be closer to the base frame member than the longitudinal center of the array. The housing may be disposed at the longitudinal center of the panels. The housing may be configured to slide from a retracted position in the open space below the array to an access position extending laterally from the array. The base member may include a first beam and a second beam, each beam defining a passage and spaced apart to accommodate the forks of a standardized forklift. The housing may include one or more input sockets for powering the solar energy device, and one or more output sockets for access to electrical energy generated and / or stored by the solar energy device. The solar energy device may also include a transverse base frame member extending laterally along the solar energy device, a first junction box extending along the transverse base frame member, a second junction box extending along the transverse base frame member, and a second housing disposed in the open space. The array may be connected to a flexible fabric. The solar energy device may also include a cable management frame. The cable management frame may include a vertical section, a longitudinal section extending along the longitudinal direction of the solar device (the longitudinal section being located at the middle of the vertical section), a plurality of hooks extending from the longitudinal section, and a plurality of buffers extending from the longitudinal section.

[0005] In some embodiments, the solar energy device includes a battery energy storage component disposed within the housing, as well as control components and electronics.

[0007] In some embodiments, the solar energy device further includes an additional array movable relative to the array. The additional array has a curvature substantially matching the convexity of the array. The solar energy device may also include a cable management system configured to maintain a constant distance along the travel path of cables extending between the additional array and the housing throughout the entire range of movement of the additional array. The cable management system may include a first arm and a second arm connected in series, wherein a first end of the first arm is located at a fixed point on the frame of the array, and a second end of the second arm is located at a fixed point on the additional array. The cable management system may also include a track and a trolley slidable along the track, wherein a joint between the first arm and the second arm is disposed at the trolley.

[0008] In some embodiments, the solar panel further includes corner posts. In some embodiments, the solar panel includes clamps and connectors, the clamps being configured to laterally span the roof of the mobile building, and the connectors connecting the corner posts to the clamps. The solar panel may also include support legs connected to the clamps and extending along the height direction of the mobile building. In some embodiments, the height of the corner posts is greater than the height of the array, for example, enabling the corner posts to be used to stack the solar panels on or under additional solar panels.

[0009] In some embodiments, a solar panel includes a solar module. The solar module includes a first solar device, a second solar device, and a bracket. The first solar device includes a first housing, a first photovoltaic panel array, and a first base frame member. A convexity along the longitudinal direction of the first solar device defines an open space below the first array, wherein the first housing is disposed within the open space. The first base frame member extends longitudinally along the first solar device. The second solar device includes a second housing, a second photovoltaic panel array, and a second base frame member. The bracket extends longitudinally along the first solar device. The bracket is configured to support the first base frame member and the second base frame member and is connected to the mobile building.

[0010] In some embodiments, a solar panel includes a first solar device for a first mobile building and a second solar device for a second mobile building. The first solar device includes a housing and a photovoltaic panel array. A convexity along the longitudinal direction of the array defines an open space below the array, wherein the housing is disposed within the open space. The first solar device is configured to be electrically connected to the second solar device. Attached Figure Description

[0081] Referring generally to the accompanying drawings, solar energy devices for modular buildings or other mobile structures (e.g., storage containers, shipping containers) according to various embodiments are illustrated. The teachings of this document provide a solar energy device that can be easily mounted on a mobile structure and includes photovoltaic (PV) panels (sometimes referred to as “solar panels”) configured to convert solar radiation into electrical energy, and onboard electronics (e.g., power electronics, inverters, batteries, or other energy storage devices) for processing the electrical energy generated by the PV panels. According to the teachings of this document, the PV panels and onboard electronics can be provided together in a modular solar energy device, which can then be easily deployed in the field without wiring or further configuration and installation of such electronics in the field. The various structural features of the solar energy device described herein further facilitate easy deployment, which will be described in more detail below.

[0082] Now for reference Figures 1 to 5C The image shows a view of a solar energy device 100 according to some embodiments. Figures 1 to 4 A solar panel 100 deployed on a mobile structure 102 is shown. Figures 5A to 5C A solar energy device 100 without a moving structure 102 is shown.

[0083] As shown in the figure, the mobile structure 102 is a transport container. In some embodiments, the mobile structure 102 is a mobile and / or modular building, such as having a size substantially similar to a standard transport container and being configured as an office or various space structures for personnel, equipment, etc. The dimensions of the mobile structure 102 can be set to be suitable for transport using standard transport network equipment and infrastructure (e.g., trucks, highways, trains, railways, etc.).

[0084] The illustrated solar panel 100 is mounted on top (roof) of a movable structure 102. The solar panel 100 includes a first end 104, a second end 106 opposite to the first end 104, and a curved frame 108 extending from the first end 104 to the second end 106. The first end 104 and the second end 106 are substantially the same width as the longitudinal ends of the movable structure 102, and the curved frame 108 is substantially the same length as the movable structure 102, such that the length and width of the solar panel 100 substantially match the length and width of the movable structure 102. For example, the first end 104, the second end 106, and the curved frame 108 may have dimensions consistent with the length and width of a standard shipping container (e.g., as defined by the International Organization for Standardization). The solar panel 100 also includes columns 110 disposed at its corners (i.e., at the lateral ends of the first end 104 and the second end 106), which are aligned with the corners of the movable structure 102. The illustrated solar device 100 also includes at least one base frame member 112, which extends between a first end 104 and a second end 106 and is configured to provide structural support for the solar device 100.

[0085] The illustrated solar energy device 100 also includes a first PV cell array 114 disposed along a curved frame 108 and fixed in position relative to the curved frame 108, a second PV cell array 116 movable relative to the curved frame 108, and a third PV cell array 118 movable relative to the curved frame 108. Figure 1 , Figure 3 , Figure 4 and Figure 5A The diagram shows the retracted (folded, unused) position of the second array 116 and the third array 118 below the first array 114. Figure 2 The diagram shows the second array 116 and the third array 118 in their deployed (extended, in use) positions, with the second array 116 located on the first side of the first array 114 and the third array 118 located on the other side of the first array 114. When the second array 116 and the third array 118 are in their retracted positions (e.g., ...), the diagram also shows their extended (used) positions. Figure 1 When the first array 114 (as shown) is in the deployed position, little or no solar energy is incident on its PV cells. When the second array 116 and the third array 118 are in the deployed position, solar energy will be incident on the first array 114, the second array 116, and the third array 118. Therefore, in the deployed position, the PV cells of the first array 114, the second array 116, and the third array 118 are suitable for collecting solar energy and generating electricity.

[0086] In the illustrated embodiment, the second array 116 and the third array 118 are mounted on rails, drawer mechanisms, etc., so that they can slide between a retracted position and an extended position. The second array 116 can be repositioned independently of the third array 118, and vice versa. As shown, the second array 116 and the third array 118 are substantially parallel to each other and substantially parallel to the first array 114 and the curved frame 108. In other embodiments, the first array 114, the second array 116, and / or the third array 118 are configured to tilt to the extended position in use, for example, rotating towards the sun to maximize direct solar radiation. In the illustrated embodiment, the curvature of the first array 114, the second array 116, and the third array 118 can facilitate efficient collection of solar energy at various solar incidence angles (e.g., as the sun moves throughout the day), without the need for complex electrically operated tilting mechanisms, etc.

[0087] from Figure 4 As can be seen from the side view, the curvature of the first array 114, the second array 116, and the third array 118 provides a space (open volume, recess, recess, etc.) 120 below the first array 114, the second array 116, and the third array 118, for example, between the base frame member 112 and the third array 118. The solar energy device 100 includes at least one housing 122 disposed in the space 120, located between the base frame member 112 and the first array 114, the second array 116, and the third array 118. See below for reference. Figures 7 to 12 In further detail, the at least one housing 122 can accommodate power electronic devices, inverters, batteries, control circuits, etc., for solar power generation from the PV cells of the first array 114, the second array 116, and the third array 118. Advantageously, by being situated within the space 120 provided by the curvature of the first array 114, the second array 116, and the third array 118, the at least one housing 122 and its contained electronic devices or other components can be transported and installed together with the rest of the solar energy device 100, eliminating the need for separate transport and ordering of individual electronic components, as well as on-site installation of individual electronic components. Thus, the solar energy device 100 provides a complete, modular solar power generation system.

[0088] Now for reference Figures 6 to 7The diagram illustrates a cable management system 600 included in a solar energy device 100 according to some embodiments. The PV cells of a first array 114, a second array 116, and a third array 118 are configured to output current to electronics in at least one housing 122 via conductive paths (wires, cables). Since the second array 116 and the third array 118 are movable relative to the housing 122, the cable management system 600 is provided to prevent such wires or cables from restricting the movement of the second array 116 and the third array 118, while allowing repeated movement of the second array 116 and the third array 118 without requiring the user to disconnect and reconnect the wires or cables.

[0089] like Figures 6 to 7 As shown, the cable management system 600 includes a first arm 602 extending from a fixed point 604 on a first end 104 (i.e., a point fixed relative to the first end 104 of the solar device 100) to a trolley 606 mounted on a track (rod) 608 connected to the underside of a third array 118. The track 608 is fixed relative to the third array 118, the trolley 606 is configured to translate (e.g., slide) along the track 608, and the first arm 602 is pivotally connected to the trolley 606 and the fixed point 604. Movement of the third array 118 correspondingly causes the trolley 606 to translate along the track 608, while the first arm 602 rotates to maintain a rigid connection between the track 608 and the fixed point 604 on the first end 104.

[0090] The cable management system 600 also includes a second arm 610, which is pivotally connected to a trolley 606 and a fixed point 612 on the third array 118 (i.e., a fixed point relative to the third array 118). Movement of the third array 118 causes the trolley 606 to translate along the track 608, while the second arm 610 rotates to maintain a rigid connection between the track 608 and the fixed point 612 on the third array 118.

[0091] Therefore, the cable management system 600 is configured to continuously define a constant-length path between a fixed point 604 on the first end 104 and a fixed point 612 on the third array 118 via a first arm 602 and a second arm 610. Thus, one or more cables (wires, wire bundles, etc.) 614 can extend along this constant-length path, specifically from the PV cell of the third array 118 to the fixed point 612 on the third array 118, along the second arm 610 to the trolley 606, and then along the first arm 602 to the fixed point 604 on the first end 104 (e.g., the one or more cables are connected to the first arm 602 and the second arm 610). Since the path maintains the same length during the movement of the third array 118 relative to the first end 104, the one or more cables 614 remain connected throughout the entire range of movement of the third array 118 without breaking, without unintentionally hindering the movement of the third array 118, without bunching, tangling, or otherwise hindering the smooth and repeated unfolding and retraction of the third array 118.

[0092] Now for reference Figure 7 The illustration shows a panel view of the operation of the housing of a display solar device 700 according to some embodiments. Figure 7 The configuration of the solar energy device 700 shown is basically the same as that of the solar energy device 100 described above, except that the second array 116 and the third array 118 are omitted. Therefore, Figure 7 A single-array solar energy device 700 is shown. In various embodiments (including solar energy device 100), at least one housing 122 of the solar energy device 100 may be configured as described or shown in the housing of the solar energy device 700.

[0093] Figure 7 The schematic diagram illustrates the operation of the housing of the solar device 700 through frames 702, 704, and 706, showing the component arrangement of the solar device 700 at different times. In frame 702, the first housing 708 is shown in a retracted position within the space created by the curvature of the PV cell array 710 of the solar device 700. The first housing 708 is positioned at the longitudinal midpoint between the array 710 and the solar device 700, so as to be located at the position where the curvature of the array 710 creates the maximum vertical space below the array 710. As shown in frame 702, the first housing 708 is in the retracted position, so that the housing is within the overall space occupied by the solar device 700 itself, thus eliminating the need for separate installation of the first housing 708 and the need to reserve additional dedicated space outside the solar device 700.

[0094] To switch from the arrangement of the first frame 702 to the arrangement of the second frame 704, the first housing 708 moves (e.g., slides) from the retracted position shown in the first frame 702 to the maintenance position shown in the second frame 704. In this maintenance position, the first housing 708 extends laterally from the array 710, i.e., is pulled out from below the array 710. The first housing 708 may be configured with a drawer mechanism or the like to facilitate selective repositioning of the first housing 708 between the retracted position of the first frame 702 and the maintenance position of the second frame 704.

[0095] The second frame 704 also shows a second housing 712 of the solar device 700 extending from the lateral side of the array 710 opposite the first housing 708. The second housing 712 may be configured substantially the same as the first housing 708, such that the solar device 700 includes a housing accessible from either lateral side of the solar device 700. The first housing 708 and the second housing 712 can be manually and repeatedly repositioned by the user to switch between the arrangement of the first frame 702 and the arrangement of the second frame 704 (in either direction). In some embodiments, similar to... Figure 6 The cable management system shown is used to facilitate the movement of the first housing 708 and the second housing 712.

[0096] To switch from the arrangement of the second frame 704 to the arrangement of the third frame 706, the first housing 708 is opened. As shown, the cover 714 of the first housing 708 is lifted (e.g., removed, rotated) to allow access to the interior of the first housing 708 and the components located therein. The cover 714 may be hinged to the lower portion 716 of the first housing 708, or it may be a separate component that can be lifted from the lower portion 716. With the cover 714 open, a person can access the contents of the first housing 708, such as power storage devices (e.g., batteries), power electronic devices (e.g., one or more inverters), and control devices (e.g., as described below). Figure 14 (The handheld controller shown), or other tools or devices that may be stored in the first housing 708 and / or the second housing 712.

[0097] By closing the cover 714 of the first housing 708 (and similarly closing the second housing 712) and translating the first housing 708 and the second housing 712 toward the centerline of the array 710, the solar device 100 can be switched from the arrangement shown in the third frame 706 back to the arrangement shown in the first frame 702, placing the first housing 708 and the second housing 712 in the stowed position shown in the first frame 702. Thus, the contents of the housings 708 and 712 can be repeatedly accessed and stowed.

[0098] Now for reference Figures 8 to 9A detailed cross-sectional view of a housing assembly 800 according to some embodiments is shown. The housing assembly 800 includes a first housing 708 and a second housing 712 (the cover 714 of the first housing 708 and the cover of the second housing 712 are hidden in the figure). The housing assembly 800 is also shown as including a first beam 802 and a second beam 804 extending between longitudinal base frame members 806 of the solar device 700 (e.g., base frame member 112 of the solar device 100). The first beam 802 and the second beam 804 are connected to the longitudinal base frame members 806 (e.g., by welding, bolting, etc.) to connect the housing assembly 800 to the remainder of the solar device.

[0099] The first housing 708 and the second housing 712 are disposed between the first beam 802 and the second beam 804, and are connected to the first beam 802 and the second beam 804 via a drawer mechanism 808, for example, connected to the inner (inner) portion of the first beam 802 and the second beam 804. The drawer mechanism 808 may be configured with rails, rollers, telescopic members, slide rails, etc., and is configured to allow the first housing 708 and the second housing 712 to slide between a retracted position and an access position, such as... Figure 7 As shown and as described above.

[0100] The first beam 802 and the second beam 804 are configured to accommodate the forks of a standardized forklift. Specifically, the first beam 802 and the second beam 804 are hollow to define a passage (access, opening, receiving cavity, etc.) through each of the first beam 802 and the second beam 804, and are spaced apart to facilitate alignment with the forks of a forklift (or telescopic forklift, etc.). The first beam 802 and the second beam 804 are connected to the base frame member 806 so that the entire solar energy device can be moved by extending the forklift forks into the first beam 802 and the second beam 804. Therefore, the first beam 802 and the second beam 804 facilitate the installation, removal, repositioning, transportation, etc., of the solar energy device described herein, such as moving the solar energy device onto a mobile structure. Figures 1 to 4 , Figure 7 , Figure 20 The arrangement is as shown.

In various embodiments, the second housing 712 (or any other or additional housings in the various embodiments) may include similar input and / or output structures. Although Figures 38 to 40 Standardized socket structures used in certain regions (e.g., the United States) are shown, but this disclosure considers any and all modifications to such structures (and associated voltages, currents, etc.) to make the teachings herein applicable to different electrical socket standards in other regions.

[0124] Figure 38 An input interface 3800 is shown located at the lower part 716 of the first housing 708. The input interface 3800 is a 120-volt alternating current (VAC) input interface. The input interface 3800 is configured to interface with a power line / cable (e.g., a standard extension cord) to receive power (e.g., 120VAC) from an external source, such as an external generator (e.g., an internal combustion generator, other solar arrays, wind turbines, other renewable energy generators, etc.), energy storage device (e.g., a battery system), or the power grid. The power electronics of the first housing 708 may be adapted to receive and utilize power from the input interface 3800, for example, for the electrical operation of solar energy equipment when solar energy is insufficient and / or for charging the batteries of the solar energy equipment with the received electrical energy. Figure 38 As shown, the input interface 3800 may be recessed into the lower portion 716 of the first housing 708 and may include a cover (e.g., a hinged cover) configured to protect the input interface 3800 when not in use (e.g., to prevent the intrusion of debris, moisture, etc.).

The output interface 3900 can also be configured to transmit power to an external source, such as for storage in an external energy storage device (e.g., a battery system) or to the power grid. The output interface 3900 is electrically connected to power electronics in the lower portion 716 to obtain power at a standard voltage (e.g., 120VAC) (e.g., from the battery cell 810, from the solar cell that outputs power, etc.) and output it to such external devices. Therefore, the output interface 3900 provides a user-friendly, fast, and easy way to draw power from solar-powered devices and / or stored electrical energy for use by any electrical equipment (e.g., computers, air conditioners, heaters, fans, external battery packs, lighting, power tools, other appliances, etc.). Figure 39 As shown, the output interface 3900 may include a cover (e.g., a flexible cover) configured to protect the output interface 3900 when not in use (e.g., to prevent the intrusion of debris, moisture, etc.).

As shown, the output interface 4006 is a 50-amp output interface (e.g., a 120 / 240VAC output interface). Compared to output interface 3900, output interface 4006 can provide higher voltage, higher current, etc., and is suitable for, for example, providing power input to the electrical system of a mobile building, for charging electric vehicles, and / or for any other system or appliance operating on such a power source. Output interface 4006 is electrically connected to the power electronics of a solar energy device that provides power at a desired current, voltage, etc. (e.g., in normalized values) derived from the solar energy device's batteries and / or solar cells. As shown in the first frame 4000 and the second frame 4002, the housing 4004 can be manually operated to provide the user with selective use (e.g., for insertion and removal) and protection (e.g., to prevent the intrusion of debris, moisture, etc.) of the output interface 4006.

[0127] Advantageously, input interface 3800, output interface 3900, and output interface 4006 provide various options for supplying power to and receiving power from the solar energy device taught herein. Therefore, the solar energy device of this invention can be easily connected to a wide variety of external devices, electrical systems, etc., without the need for direct on-site electrical wiring (e.g., without the need for an electrician or other technical personnel). This structure facilitates the easy mobile deployment of the solar energy device of this invention for use in temporary buildings, storage containers, mobile buildings, mobile offices, etc., spanning a wide range of use cases, including directly supplying power to external appliances without intermediate electrical infrastructure.

Figure 41 As shown, housing 4100 includes access door 4102, which can be opened to access the interior of housing 4100, for example, without requiring the user to refer to the above description. Figure 7 The housing 4100 is removed from its retracted position as discussed. The access door 4102 is configured to be locked to prevent unauthorized access to the controllers inside the housing 4100 (e.g., to prevent operation of start / stop controllers, etc., installed inside the housing 4100). Figure 43 Various switches, circuit breakers, reset buttons and / or other components (illustrated as operable electronics 4300) that a user may wish to operate can be located inside housing 4100 and near access door 4102, so that operable electronics 4300 can be easily accessed through access door 4102.

The first end 5002 includes a first junction box (illustrated as a DC junction box 5006) and a second junction box (illustrated as an AC junction box 5008). The first end 5002 of the solar energy device 5000 (including the DC junction box 5006 and the AC junction box 5008) also... Figure 45 As shown in the diagram, the first end 5002 of the solar device 5000 also includes a QR code 5010. A user scans the QR code 5010, which directs them to an application or website. This application or website includes information related to the solar device 5000 (e.g., customer group, unit type, number of racks, charging status, system temperature, output power, generator information, state of charge (SOC), etc.). In some embodiments, the application or website includes a location map of all solar devices. In some embodiments, the application or website includes information about a specific solar device (e.g., serial number, battery capacity, solar power, load power, diesel CO2 emission reduction, location, customer, unit type, etc.).

In some implementations, when the AC junction box 5008 is in an active state, the LED 5012 emits a first light mode, and when the AC junction box 5008 is in an inactive state, it emits a second light mode (e.g., when the AC junction box 5008 is in an active state, the LED 5012 flashes once every 1 second, and when the AC junction box 5008 is in an inactive state, it flashes once every 5 seconds, etc.). Connecting the DC junction box 5006 and the AC junction box 5008 to the first terminal 5002 of the solar energy device 5000 allows users (e.g., technicians, etc.) to easily make various electrical connections without requiring an electrician to perform direct field wiring during installation.

In the illustrated embodiment, the cable management frame 5044 includes two pairs of hooks 5051. In other embodiments, more than two pairs of hooks are present depending on cable management requirements (e.g., a third pair of hooks is added between the buffers 5052, etc.).

[0151] Layout of implementation methods When the terms “about,” “approximately,” “substantially,” and similar terms are used herein to describe structural features (e.g., describing their shape, size, orientation, direction, etc.), these terms are intended to cover minor structural variations that may result from, for example, manufacturing or assembly processes, and are intended to have a meaning consistent with the broad meaning commonly used and accepted by one of ordinary skill in the art to which the subject matter of this disclosure pertains. Therefore, these terms should be interpreted as indicating that non-substantial or insignificant modifications or alterations to the described and claimed subject matter are considered to be within the scope of this disclosure as set forth in the appended claims.

[0152] As used herein, the term "connection" and its variations mean linking two components directly or indirectly to each other. Such a connection can be static (e.g., permanent or fixed) or movable (e.g., removable or releasable). This connection can be achieved by directly linking the two components, by linking the two components using a separate intermediary component and any additional intermediate component, or by linking the two components using an intermediary component integrally formed with one of the two components. If "connection" or its variations are modified by an additional term (e.g., direct connection), the general definition of "connection" provided above is modified by the colloquial meaning of the additional term (e.g., "direct connection" means linking two components without a separate intermediary component), resulting in a narrower definition than the general definition of "connection" provided above. Such a connection can be mechanical, electrical, or fluid.

[0153] References to element locations (e.g., "top", "bottom", "above", "below") herein are used only to describe the orientation of the various elements in the accompanying drawings.
