Solar photovoltaic power generation system consists of three parts: solar cell modules; Charge and discharge controller, frequency converter, test instrument and computer monitoring and other power electronic equipment and storage battery or other energy storage and auxiliary power generation equipment.
Solar photovoltaic power generation system has the following characteristics:
- no rotating parts, no noise;
- no air pollution, no waste water discharge;
- no combustion process, no fuel required;
- simple maintenance, low maintenance cost;
- operational reliability and stability;
- the long life of solar cells is a key component of solar cells. The life of crystalline silicon solar cells can reach more than 25 years.
