Definitions
- the present invention relates to a vertical photovoltaic system and a method for installing such a system. It applies, in particular, to the field of the production of energy from renewable sources.
- agrivoltaism also known by the acronym of “Agri-PV”, or “APV”.
- the installation of photovoltaic systems as envisaged in the prior art requires a large quantity of material, such as steel or aluminum.
- material such as steel or aluminum.
- the use of one or more horizontal structuring elements of significant length arranged above the module and fixed between two posts is essential for the stability of the system.
- these upper horizontal elements cause shading on the module during use of the system, causing a decrease in solar radiation irradiating the modules and thus limiting the efficiency of the system.
- the presence of one or more upper horizontal elements also decreases the spatial and geometric adaptability of photovoltaic systems.
- German utility model DE 20 2020 104397 which discloses a vertical photovoltaic system comprising at least one module fixed on its longer side to a pole.
- the photovoltaic panels are adjacent and juxtaposed against each other.
- Such a juxtaposition requires a very specific support "framework" comprising in particular at least two horizontal crosspieces connecting the load-bearing posts.
- Japanese patent application JP 2002 076416 discloses a photovoltaic system in which the modules are fixed to the posts by their shortest side and are therefore arranged vertically in the manner of a “landscape” format. This photovoltaic system has a structural horizontal upper bar.
- the present invention aims to remedy all or part of these drawbacks.
- the invention relates to a vertical photovoltaic system, which comprises:
- each module comprising:
- long sides two other sides, called “long sides”, having a length greater than or equal to a length of at least one short side
- each said post comprising:
- each photovoltaic module being directly connected, by its two long sides, to means for fixing two consecutive support posts.
- directly connected means that there is no other photovoltaic module between a long side of a photovoltaic module and a pole. It does not prohibit the presence of connecting pieces between the long side of a photovoltaic module and the post to which it is connected and which supports it.
- the inventors have determined that the invention allows a lightening, reduction, or even elimination, of the structure connecting two poles bearing the same photovoltaic module.
- the invention also allows a simplification of the design, the profile and the manufacture of these load-bearing posts, as well as a relief of these posts.
- the photovoltaic modules are supported by their two long sides, the bending forces exerted on these modules are reduced compared to a support on the two short sides, as well as their bending, so that their structural elements of stiffening can also be reduced, lightened or absent.
- additional supports are provided to the module by fixing a long side of the module to a post, allowing it to be arranged in a so-called “portrait” configuration.
- the resistance of the system to mechanical stresses is therefore improved.
- a fixed, stable and vertical bifacial photovoltaic system is installed on the ground.
- the system also makes it possible to reduce the footprint on the ground and in particular to increase compatibility with agricultural activity on the installation ground. This system is thus compatible with agrivoltaism.
- the system thus installed also has a low hydrological impact on the plantations when it is placed on agricultural land.
- the system is modular and thus allows a simplified, fast and flexible installation.
- the system can be easily adapted according to the constraints inherent to the installation site and the constraints of use. For example, such a system is easily installed on sloping ground.
- the replacement of a part or a module, for example damaged is facilitated since the system can be disassembled and reassembled easily and quickly.
- the specific replacement of this zone can be carried out without the dismantling of the rest of the installation being necessary.
- These provisions also make it possible to use photovoltaic modules of a significant diversity, presenting, for example, different sizes or a specific organization of the chains of cells.
- the system does not include a horizontal structural element, connecting two poles, arranged above the short side of a photovoltaic module furthest from the ground. Thanks to these arrangements, the amount of installation material is reduced. Thus, the cost of the installation is reduced, limiting its environmental impact.
- the system allows improved management of the light irradiating the photovoltaic modules by limiting the shading caused by the use of a more complex structure comprising in particular the upper horizontal element. Indeed, the system allows maximum irradiation at the front and rear of the modules. Thus, the amount of electricity produced is increased.
- the fixing means has a plurality of fixing positions configured to move a module away from or closer to the ground according to the height of the fixing position.
- the height of the post can be adapted to the different wind zones in order to allow a greater or lesser spacing of the fixings of the photovoltaic module.
- the fasteners are present on parts near the middle of the long sides of the photovoltaic module.
- the fixings are present on parts farther from the middle of the long sides of the photovoltaic module.
- the posts it is not necessary for the posts to have lengths greater than the height of the highest attachment point of the module.
- posts of variable length are used.
- at least one fastening means comprises:
- these provisions make it possible to adapt the fixing according to the mechanical constraints applied to the photovoltaic system.
- the post has one or more oblong-shaped holes
- the bolt and nut assembly allows for precise dimensional tolerance.
- the clip system allows attachment from the rear of the module mounting frame, thus preventing the module from detaching from the post.
- At least one post has a transverse profile in the form of:
- the system has limited vertical shading on the back side of the module.
- the transverse profiles when the post is made of at least partially reflective material, allow optimal reflection of sunlight on the photovoltaic module. Thus, the gain in electrical production is increased.
- the transverse profiles facilitate the use of the fixing means by increasing the compatibility between the post, the fixing means and the module.
- the system includes: - at least one crosspiece arranged under the short side of a photovoltaic module closest to the installation floor and having ends and
- each said connecting means being configured to fix a separate end of at least one said crosspiece to a post, said crosspiece being arranged and fixed between at least two posts.
- the crosspiece improves the stability and mechanical resistance of the system. Furthermore, the crosspiece makes it possible in particular, when it is placed below and in contact with a module, to reinforce the vertical and height support of the module subjected to gravity.
- At least one crosspiece has an inverted G or U-shaped transverse profile.
- At least one crosspiece is configured to at least partially enclose at least one post.
- the system has a more compact overall structure, thus making it possible to reinforce the stability of the structure.
- At least one crosspiece comprises an upper rim in contact with the module and a lower rim configured to retain electrical cables connected to the photovoltaic module.
- the electrical cables are protected and oriented according to the predetermined constraints of use of the photovoltaic system.
