I. Introduction
Due to the development of industrial technology, energy consumption is increasing day by day, which makes the problem of energy shortage more and more prominent. At the same time, global electricity consumption is also increasing dramatically, and the finite fossil fuels and the unlimited growth of electricity demand have made it a great concern for countries to replace traditional energy generation with existing renewable energy sources. Among them, photovoltaic power generation has developed rapidly in recent years, and the energy of photovoltaic power generation is solar energy, which has the advantages of clean, safe and inexhaustible, and occupies an important position in new energy power generation.
