Solar photovoltaic power generation system is of a new type of power generation systems which uses photovoltaic effects of the sun battery semiconductor materials, to convert the solar radiation directly into electricity. It has two ways of operation -independent operation and grid operation. The independent photovoltaic power generation system needs to have accumulator as a storage device, mainly used in remote areas and scattered areas without power grid, and the whole system costs a lot. In the area with public power grid, photovoltaic power generation system connects with the power grid and operates simultaneously. It needs no battery, not only can reduce the cost, but also has higher efficiency and better environmental performance.

Solar power is divided into photo-thermal power generation and photovoltaic power generation. Solar power is often referred to photovoltaic power generation, abbreviated as ‘Photo-electricity’. Photovoltaic power generation is a technology that uses the photoelectric voltage effect of the semiconductor interface to convert light energy directly into electricity. The key component of this technology is solar cells. The solar cell can form a large area of solar cell units after they are connected, and then the photovoltaic power plant can be formed with the power controller and other parts.
