Description

Title of the invention: MOBILE INDIVIDUAL SOLAR POWER GENERATION STATION

[0001] The invention relates to the creation of a mobile solar station with a solar tracker (2-axis tracking) incorporating photovoltaic solar panels and all the components necessary for electricity production. A single electrical cable from the solar station makes it possible to partially or fully power all the 220V electrical appliances in a house.

[0002] The mobile solar station can be delivered to the customer turnkey. Its installation is quick and requires no knowledge in the field of electricity, making it accessible to everyone.

[0003] This embedded system does not require any remote technical room (garage, shed etc.) because the components such as batteries, charge regulator, converter or 12v / 220v inverter are integrated into the vehicle in a sealed box under the solar panels.

[0004] This solar vehicle supports photovoltaic panels that move with the vehicle, following the sun's path to optimize electricity production. A solar cell controls the vehicle's movement motors from east to west and manages the north-south tilt of the panels using actuators mounted on the articulated panels. The solar station can also move automatically according to a program thanks to its motorized directional wheels, following a predetermined path. This allows the panels to avoid areas shaded by trees and buildings, thus optimizing electricity production throughout the day.

[0005] The invention relates to a motorized device for permanently exposing and moving solar panels perpendicularly to the sun at any time of day along a predetermined sunny path avoiding areas of shadow cast on the panels.

[0006] In this respect, the device is characterized by a control system, using a solar cell, for the 4 motorized wheels of the station in such a way that these allow the solar panels to follow the course of the sun from east to west.

[0007] In this respect, the device also allows, by means of a program, the motorized wheels to be controlled in order to automatically move the station towards sunny areas (see pl,p2,p3)

[0008] State of the art:

[0009] Currently, almost all photovoltaic panels are ground-mounted, which requires a metal structure to support the panels, as well as metal trays filled with stones or sand, or posts fixed in concrete to stabilize the installation. Furthermore, in this configuration, the panels are fixed and generally oriented to the south. They capture very little solar energy from either the east or the west. Electricity production is therefore not optimal without a solar tracker.

[0010] In the innovation which is the subject of a provisional patent application, the solar panels are fixed to the chassis of a solar vehicle, which eliminates any fixing of the panels to the ground on fixed metal supports, which represents a significant saving and a better performance of the solar panels thanks to the tracking of the sun's path integrated into the vehicle.

[0011] This innovation has the advantage of allowing the solar station to be moved in 2 ways:

[0012] *either in the form of a solar tracker by controlling the motorized wheels using a solar cell (east-west rotation management)

[0013] * either by controlling the station's motorized wheels via a program to make it follow a programmable route.

[0014] The other advantage of this mobile on-board solar station is that it can be dismantled, moved and installed in any location where electricity needs to be produced (off-grid areas, unconnected bungalows, festive events, etc.).

[0015] DESCRIPTION OF THE ONBOARD SOLAR STATION:

[0016] The solar station consists of a chassis on which 4 motorized directional wheels are fixed. The movement of the station is controlled either by a remote control in manual mode or by a solar cell which controls the rotation of the motorized wheels (azimuth) or by a program allowing the station to follow a path.

[0017] The station can rotate on its own axis in a circle (solar tracker mode) thanks to its four motors and four actuators, which allows it to follow the sun's east-west path. (see diagram P2)

[0018] The solar panels are installed on a structure which is itself connected to the chassis by an articulation system allowing the solar panels to be tilted (north-south). Electric actuators connect the solar panels to the chassis, which allows the tilt of the panels relative to the sun to be controlled.

[0019] On the chassis there is a box to house all the electrical components such as electrical boxes, batteries, mppt charge regulator, inverter, 12v / 220v converter, solar tracker control box.

[0020] FOLLOWED BY A SUNNY ROUTE (sketch page 1)

[0021] The solar station is equipped with a guidance system (GPS, wired, or a learning path) that allows it to move and continuously follow sunny areas. This mobility of the station allows the panels to avoid shadows cast by trees in gardens and buildings, which would otherwise result in a complete lack of electricity production. This system optimizes 100% of the solar energy that can be produced in any location. The combined efficiency of the solar tracking system and the "sun-seeking path" allows for energy capture optimization exceeding 60% compared to fixed installations.

[0022] NOVELTY OF INNOVATION

[0023] Currently, ground-mounted solar installations are delivered as kits by specialized companies. These kits consist of photovoltaic panels, converters, inverters, batteries, etc., for self-assembly. These kits are intended for people capable of carrying out their own installation, which excludes many people who would like to produce solar electricity at home but lack the necessary skills.

[0024] The aim of the invention is to democratize solar electricity production by bringing to market a turnkey, mobile, on-board solar station accessible to all. This means that instead of delivering solar kits with separate components to be connected, it will be possible in the future, thanks to this innovation, to deliver a turnkey, integrated, and immediately operational installation with a very simple assembly process.

[0025] This innovation has a novel character because there is no similar product on the market.

[0026] Several types of photovoltaic installations can be found on the market. • On the roof. The disadvantage is that it visually degrades the environment, captures only part of the solar energy (poor exposure, unsuitable roof slope) and requires the use of an approved installer, hence a high cost. • Ground-mounted. Most ground-mounted installations using kits are fixed. The panels face south with a fixed or even adjustable tilt. The panels are supported by metal structures resting on weighted trays. The electrical components for electricity production are located in a shelter, garage, etc., which necessitates digging a trench to connect the solar panels to the technical room. The efficiency of fixed panels is lower because they do not follow the movement of the neither sun nor do they move to escape the shadows cast by nearby trees and buildings. • There are also systems for mounting solar panels on metal masts sealed in concrete and equipped with geared motors, allowing for the creation of a solar tracker. These installations are very expensive and only suitable for very large solar panel areas (e.g., in agricultural settings) but are not appropriate for private individuals.

[0027] NOTE: • All these ground-mounted, kit-based installations currently lack an integrated system, meaning no housing for the electrical components under the panels, no solar trackers, and no possibility of installation mobility. Furthermore, the kits available on the market require self-assembly and are therefore reserved for specialists, which hinders national production of this renewable energy.

[0028] The proposed innovation is novel because it provides a solution to all the problems posed by current installations. 1. The installation is integrated; no technical room is needed. 2. Electricity production is optimized through motorization, which allows the solar vehicle to move according to the sun's path and the shadows cast by trees and buildings near the panels. 3. The installation is mobile, allowing electricity to be produced wherever desired. This mobility means the solar vehicle can be loaned, rented, or resold (for moving, relocating to a second home, etc.), which is a considerable advantage compared to a fixed installation. 4. The installation is delivered turnkey, ready to operate; no kit assembly is required. Anyone can install a solar power system at home without any prior knowledge in the field.

[0029] INVENTIVENESS CREATIVITY

[0030] The invention of an on-board, mobile solar station with solar tracker, intended for the production of electricity in an autonomous site is the synthesis of several systems which have been grouped into one.

[0031] This invention is innovative because it brings together, for the first time in one place on a mobile vehicle, solar panels and all the components necessary for electricity production. The motorization of the vehicle carrying all the components, powered by a solar cell, allows the vehicle to be driven, moved, and the panels to be constantly oriented towards the sun, thus optimizing electricity production. The innovation also lies in the nature The installation is mobile thanks to its motorization, which allows it to move to any point on the ground according to a program to be located on a permanently sunny route, thus optimizing electricity production to 100%.

[0032] INDUSTRIAL APPLICATIONS

[0033] This innovation is likely to have industrial application.

[0034] The various components of the solar station can be manufactured industrially in large series and delivered in the form of pre-assembled kits to customers who will assemble them without having any knowledge of electricity.

[0035] It is planned to industrially construct 3kwp and 6kwp solar stations capable of equipping each household with a surface area to accommodate the station (gardens, courtyards, parking lots, etc.).

[0036] The production of these stations in very large series will make their price even more accessible to individuals than current kits and thus democratize, decentralize the production of photovoltaic energy and contribute decisively to the energy transition.

[0037] Estimation of the company size required to produce 1 gigawatt of peak power / year: 300 people are needed to ensure the assembly of 170,000 stations per year, or about 700 stations / day.

[0038] The use of photovoltaic panels for electricity generation is experiencing very strong growth because it corresponds to an increasing demand from individuals to equip themselves to produce their own electricity in order to reduce their bills and be less dependent on the grid. Innovation addresses this need. It also responds to the desire of a growing number of individuals who are not solar technicians and therefore would not buy a kit to benefit from a turnkey solar electricity production system at home, eliminating the need for any assembly and delivering all the guarantees of safety and reliability, given the quality control of an industrialized product.

[0039] More broadly, the climate emergency argues for the rapid replacement of fossil fuels with clean electricity. The increasing adoption of electric vehicles by individuals supports the mass production and low cost of this type of autonomous solar station, which will cover household energy needs on-site, independently of nuclear power plants.
