Photovoltaic power generation has significant energy, environmental protection and economic benefits, and is one of the best green energy sources. Installing a 1-kilowatt photovoltaic power generation system under the average sunshine conditions in my country can generate 1,200 kWh of electricity in one year, which can reduce the use of coal (standard coal). According to the research results of the World Wildlife Fund (WWF): in terms of carbon dioxide reduction effect, installing 1 square meter of photovoltaic power generation system is equivalent to planting 100 square meters of trees. At present, the development of renewable energy such as photovoltaic power generation Energy is one of the effective means to fundamentally solve environmental problems such as smog and acid rain.
