How stable is the photovoltaic power generation system? Will it fail in a few years?

① Solar energy resources are inexhaustible. The solar energy that reaches the earth is times greater than the energy currently consumed by humans. Moreover, solar energy is widely distributed on the earth. As long as there is light, photovoltaic power generation systems can be used, without restrictions on factors such as region and altitude.

② Solar energy resources are available everywhere, and power can be supplied nearby without long-distance transmission, avoiding the loss of electricity caused by long-distance transmission lines.

③ The energy conversion process of photovoltaic power generation is simple, which is a direct conversion from light energy to electrical energy. There is no intermediate process (such as heat energy converted to mechanical energy, mechanical energy converted to electromagnetic energy, etc.) and mechanical movement, and there is no mechanical wear. According to thermodynamic analysis, photovoltaic power generation has a very high theoretical power generation efficiency, which can reach more than 80%, and has great potential for technical development.

④ Photovoltaic power generation itself does not use fuel, does not emit any substances including greenhouse gases and other waste gases, does not pollute the air, does not generate noise, is environmentally friendly, and will not suffer from the impact of energy crisis or fuel market instability. It is a truly green and environmentally friendly new renewable energy.

⑤ The photovoltaic power generation process does not require cooling water and can be installed in desert Gobi without water. Photovoltaic power generation can also be easily combined with buildings to form a photovoltaic building integrated power generation system, which does not require separate land and can save precious land resources.

⑥ Photovoltaic power generation has no mechanical transmission parts, simple operation and maintenance, and stable and reliable operation. A photovoltaic power generation system can generate electricity as long as there are solar cell modules. In addition, with the widespread adoption of automatic control technology, it can basically achieve unmanned operation and low maintenance costs.

⑦ The working performance of the photovoltaic power generation system is stable and reliable, and the service life is long (more than 30 years).
