A photovoltaic system is a system that uses solar cell components and other auxiliary equipment to convert solar energy into electrical energy. Generally divided into independent systems, grid-connected systems and hybrid systems. Since the beginning of the 21st century, the world's solar photovoltaic power generation industry has developed rapidly, and the market application scale has continued to expand. It plays an increasingly important role in the development of subsequent energy sources. The development and utilization of solar photovoltaic technology is also one of the important measures for us to implement energy conservation, emission reduction, sustainable development, and improvement of the living environment in a resource-saving society.
