[0002] Solar photovoltaic power generation is based on the principle of photovoltaic effect, using solar cells to directly convert sunlight energy into electrical energy. There are many factors that affect the power generation of solar photovoltaic panels. Solar radiation is one of the most important factors affecting the power generation of solar photovoltaic panels. Generally speaking, the greater the solar radiation, the higher the power generation of solar photovoltaic panels. Therefore, in areas with abundant solar energy resources, the power generation of photovoltaic panels is usually higher. At the same time, the ambient temperature also has a certain impact on the power generation of solar photovoltaic panels. Generally speaking, the higher the ambient temperature, the lower the power generation of photovoltaic panels. This is because as the temperature increases, the resistance inside the photovoltaic panel will increase, resulting in a decrease in current, which affects the power generation. Therefore, in hot areas, certain measures need to be taken to reduce the ambient temperature in order to increase the power generation of photovoltaic panels.
