Solar photovoltaic power generation system is the use of solar modules directly to solar energy into electrical energy generation system, which is characterized by high reliability, long service life, do not pollute the environment, both independent power generation and grid-connected operation by the national government, enterprises, Social organizations of all ages, with broad market prospects.
Solar photovoltaic power generation system is widely used, according to the basic form of application can be divided into two categories: independent photovoltaic power generation systems and grid-connected photovoltaic systems. With the development of technology and the need of sustainable economic development, the state has begun to plan the promotion of distributed grid-connected photovoltaic power generation in cities. The main purpose is to make use of urban buildings idle sun roofs, sunny vacant places, etc. Meanwhile, City lighting to promote the application of solar photovoltaic systems.
