And the price difference between the price of the double-sided photovoltaic module and the conventional single-sided photovoltaic module is not large, so that the double-sided photovoltaic module has advantages in improving the unit area generating capacity and reducing the system generating cost compared with the conventional photovoltaic module.

However, the power generation gain of the existing double-sided photovoltaic module is mainly to increase the power generation amount by reflecting the solar radiation and scattering to the back of the module after reaching the ground, the function of increasing the power generation amount by totally depending on the reflected light and the scattered light of the surrounding environment is very limited, the potential of the double-sided photovoltaic module is not fully exerted in practice, but the initial investment cost is increased, so that people think that the direct light irradiated on the surface of the double-sided photovoltaic module is reflected by a reflector to change the propagation direction so as to finally irradiate the back of the double-sided photovoltaic module, thereby improving the power generation amount of the double-sided photovoltaic module. Its structure is at two-sided photovoltaic module's below installation reflector panel, like the two-sided photovoltaic module of china utility model patent "support for two-sided photovoltaic module of two glasses", patent number: 201621234370.2, in the structure of the patent, the reflector panel can not or rarely receive the direct sunlight due to the shielding of the upper photovoltaic module, and mainly refracts the ambient scattered light to the back of the photovoltaic power generation module, so the increase of the power generation efficiency and the power generation amount is still very limited.
