The invention relates to a structure for integrally mounting a double-sided photovoltaic module and a reflecting surface, the structure comprising a module array, a reflecting surface, a bracket, anda connector for connecting the module array and the reflective surface. The bracket is arranged at the lower part of the reflecting surface, and the reflecting surface is used; The module array includes a plurality of rows of photovoltaic modules, with horizontal and/or vertical gaps disposed between each row of photovoltaic modules; Stationary support. As the vertical and lateral distance of thefront and rear rows of the component in the array are adjusted, the light rays enter the reflecting surface behind the component through the gap of the front and rear rows, thereby ensuring the frontal power generation and increasing the intensity and uniformity of the incident light; A reflective surface disposed below the assembly, By reflecting the transmitted light to the back of the module, the light receiving intensity and uniformity of the back of the module are improved, and the gaps between the modules not only improve the uniformity of the transmitted light, but also enable the modules in the array to be connected in series arbitrarily, thus avoiding a certain module to be a power generating short board, limiting the power generation of the whole array and improving the freedom of design.
