Advantages of solar photovoltaic power generation

① Solar energy resources are inexhaustible. The solar energy irradiated on the earth is 6000 times greater than the energy currently consumed by mankind. Moreover, solar energy is widely distributed on the earth. As long as there is light, photovoltaic power generation system can be used, which is not limited by geographical, altitude and other factors.

② Solar energy resources are available everywhere, which can supply power nearby without long-distance transmission, avoiding the power loss caused by long-distance transmission lines.

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

④ Photovoltaic power generation itself does not use fuel, does not emit any substances including greenhouse gases and other exhaust gases, does not pollute the air, does not produce noise, is friendly to the environment, and will not be impacted by the energy crisis or the instability of the fuel market. It is a truly green and environmentally friendly new renewable energy.

⑤ The photovoltaic power generation process does not need cooling water and can be installed on the desert Gobi without water. Photovoltaic power generation can also be easily combined with buildings to form an integrated photovoltaic building power generation system, which does not need to occupy separate land and can save valuable land resources.

⑥ Photovoltaic power generation has no mechanical transmission parts, simple operation and maintenance, stable and reliable operation. A set of photovoltaic power generation system can generate electricity as long as there are solar cell modules. Combined with the wide adoption of automatic control technology, it can basically realize unattended and low maintenance cost.

⑦ The photovoltaic power generation system has stable and reliable working performance and long service life (more than 30 years). The service life of crystalline silicon solar cells can be as long as 20 ~ 35 years. In the photovoltaic power generation system, as long as the design is reasonable and the selection is appropriate, the service life of the battery can also be as long as 10 ~ 15 years.

⑧ The solar cell module has the advantages of simple structure, small volume and light weight, which is convenient for transportation and installation. The construction period of photovoltaic power generation system is short, and the capacity can be large or small according to the power load. It is convenient and flexible, and it is very easy to combine and expand.
