Solar energy is an inexhaustible renewable energy for human beings. It has the advantages of sufficient cleanliness, absolute safety, relative universality, long life and no maintenance, sufficient resources and potential economy, etc., and it plays an important role in long-term energy strategy.Photovoltaic power generation has the characteristics of safety and reliability and is free from regional restrictions.No pollution discharge or risk of exhaustion.At present, most of China's large photovoltaic power plants are built in northwest and north China.Vast solar panels are built in the desert and other inhospitable areas to form large power plants.The high voltage fuse of xiangyuan power source is mainly supplied to the switch of pad mounted transformer in large photovoltaic factory.
