Description

A multifunctional double-sided photovoltaic module support

technical field

The utility model belongs to the technical field of photovoltaic cells, in particular to a multifunctional double-sided photovoltaic module support.

Background technique

Photovoltaic brackets are brackets used to support photovoltaic modules. As the seasons change, the altitude angle of the sun also changes, so many existing photovoltaic supports are designed to adjust the angle. For example, the patent document with the notification number CN 103165703 B discloses a photovoltaic support with adjustable installation inclination angle. The rear support is mainly fixed on the balcony, and the front support slides back and forth to change its inclination angle. displacement. The patent document with the publication number CN106100553A discloses an adjustable inclination angle photovoltaic support, which is mainly composed of an inclination adjustment rod, a telescopic rod, and a support rod in a triangular shape, and each rod is connected by a triangle connector and a bolt. Its adjustable angle is 15°～80°.

Although the above-mentioned existing various photovoltaic brackets provide convenience for the installation of photovoltaic modules and the adjustment of angles, there are still the following deficiencies:

(1) The adjustable tilt angle range is small;

(2) Nowadays, bifacial photovoltaic modules are widely used due to their high power generation. For double-sided photovoltaic modules, the power generation gain has a lot to do with the ground reflectivity of the installation site, installation height, installation inclination and other factors. The bracket designed for single-sided modules does not consider the influence of the reflectivity of the ground surface on the back side. The surface reflectance is a very important factor in the double-sided photovoltaic module power generation system. Many surface materials will age and change over time, resulting in a gradual decrease in their reflectivity. Therefore, in the double-sided photovoltaic module power generation system, it is necessary The function of replacing the ground surface to reduce the loss of power generation due to the reduction of the surface albedo;

(3) Only the angle can be changed, and the function is single.
