[0003] How to improve the effective utilization of solar energy has become a major factor restricting the development of the photovoltaic power generation industry. Many people choose gallium arsenide modules as photoelectric conversion devices, but the utilization rate of solar energy for existing gallium arsenide modules is still not high enough
In addition, since there are multiple blocks on each solar photovoltaic panel, and each block contains more than one GaAs module, it is difficult to detect when a certain GaAs module is damaged, even if it is judged that a module is damaged. It is difficult to find out its specific location, which not only seriously affects the conversion efficiency of solar energy but also increases the work intensity of maintenance personnel
