Embodiment Construction

[0050] A solar panel according to the invention is a hybrid solar module capable of generating electrical and thermal energy from solar energy. It is intended to be used alone or in combination with other similar modules within the installation, so that the energy generated by said panels should be usable, for example and in a non-limiting way, for dwellings. Conventionally, a hybrid solar module can be defined as an assembly of a photovoltaic solar module and a heat exchanger ( 5 ).

[0051] refer to Figure 1a , hybrid solar modules rely on photovoltaic modules to convert a portion of the received solar energy into electrical energy. Said photovoltaic module consists of a plurality of photovoltaic elements (3) usually crystalline silicon semiconductors, thin layers of semiconductors or any other technology capable of realizing the photovoltaic effect. These photovoltaic elements (3) are connected electrically in series or in parallel and are assembled, for example and in a ...

Abstract

At best, photovoltaic solar modules only convert 20 % of solar energy into electrical energy, the rest of this energy being dissipated. This heat stored in the photovoltaic module reduces efficiency, which decreases in an inversely proportional manner to the temperature of the photovoltaic module. To dissipate and recover this heat, it is common to associate the photovoltaic module with a heat exchanger which, in addition to cooling the photovoltaic module, will supply heat, for example to heat the sanitary water of a building. This assembly forms a hybrid solar module, whose main limitation is its weight and relatively short service life. The invention described in the present document solves these two problems by replacing the first layer of the hybrid solar module, which is conventionally a glass sheet, with a material which is lighter, less rigid, more transparent, and more compatible with the material from which is constructed the heat exchanger, which now provides the system with its rigidity. A method for manufacturing these hybrid solar modules is also described.

Description

technical field [0001] The present invention relates to the field of hybrid solar systems. The invention relates more particularly to methods enabling improved lifetime and output of the system. The invention also relates to a method of assembling a photovoltaic module to form a heat exchanger in which a cooling liquid circulates. Background technique [0002] In a manner known per se, a hybrid solar system consists of a photovoltaic solar module associated with a thermal part, also called an exchanger or absorber, responsible for cooling the photovoltaic solar module. Indeed, such a module consisting of a plurality of electrically connected photovoltaic solar elements is powered by converting solar energy within said photovoltaic cells. However, the conversion rate is difficult to exceed 20%, and the rest of the solar energy received by the system is lost. For crystalline silicon semiconductor technology, the efficiency of photovoltaic cells decreases with temperature by...
