The solar photovoltaic power generation process has no mechanical rotating parts, does not consume fuel, and does not emit any substances including greenhouse gases. Compared with other new power generation technologies, solar photovoltaic power generation is a renewable energy power generation technology with the characteristics of sustainable development. Its main advantages are as follows:

1. Solar energy resources are inexhaustible. The energy radiated by the sun to the earth is 6000 times the energy consumed by this stratum. In addition, solar energy is widely distributed on the earth. As long as there is light, the photovoltaic power generation system can be used, regardless of geographical, altitude and other factors.

2. The energy conversion process of solar photovoltaic power generation is simple, directly from photon to electron. There is no intermediate process and mechanical movement, and there is no mechanical wear.

3. The solar photovoltaic power generation itself does not use fuel, does not emit any substances, including room temperature gas and other exhaust gases, does not pollute the air, does not produce noise, is environmentally friendly, will not be affected by the energy crisis or the instability of the fuel market, is a new type of green renewable energy.

4. The solar photovoltaic power generation process does not need cooling water and can be installed on the desert Gobi without water. Photovoltaic power plants can also easily combine with buildings to form a photovoltaic building integrated power generation system that does not require separate land occupation, saving valuable land resources.

5. Solar photovoltaic power generation has no mechanical transmission parts, simple operation and maintenance, stable and reliable operation. A photovoltaic power generation system can generate electricity as long as it has solar cell modules. In addition, with the wide application of automatic control technology, it can basically achieve unattended and low maintenance costs.

6. The performance of solar photovoltaic power generation is stable and reliable, and the service life is more than 30 years. The service life of crystalline silicon solar cells can reach 20-35 years.
