solar power system

الوصف

Solar power system is divided into on-grid power system and off-grid power system. And on-grid power system is connected to the electricity transmission grid system. Through the PV modules will receive years of solar radiation energy through the high-frequency DC-converted into a high-voltage direct current through the inverter after the inverter output power to the grid voltage of the same frequency, with phase sinusoidal AC current. off-grid power system in remote villages in the area, including power supply system, solar home power system, communication signals, power supply, cathodic protection, solar lights and other battery can run independently with off-grid power system. It is predicted that solar power system in the *1st century will occupy a prominent place on the world's energy consumption, not only to replace part of the conventional energy sources, but also will become the main body of the world's energy supplies.
