First, solar energy is inexhaustible. It is estimated that the solar energy projected into the Earth during the year is equivalent to 137 trillion tons of standard coal, which is about 20,000 times the amount of energy produced by various energy sources in the world in a year.
Second, solar energy will not cause environmental pollution in the conversion process.
Third, solar energy resources are available all over the world and can be mined in a decentralized and regional manner. About two-thirds of China's regions can make good use of solar energy resources.
4. Photovoltaic power generation is intermittent, and electricity is generated when there is sunlight, and the amount of electricity generated is directly proportional to the intensity of sunlight.
5. Photovoltaic power generation is a static operation, with no moving parts, long life, and little or no maintenance.
6. The photovoltaic system is modular and can be installed near the power consumption. In areas far away from the power grid, transmission and distribution costs can be reduced, and the reliability of power supply facilities can be increased.
