①Solar energy resources are inexhaustible and inexhaustible.
②Green and environmental protection. Photovoltaic power generation itself does not require fuel, does not emit carbon dioxide, and does not pollute the air. No noise is produced.
③ Wide range of applications. The solar power system can be used as long as it can get sunlight, and it is not restricted by factors such as region and altitude.
④No mechanical rotating parts, easy operation and maintenance, stable and reliable operation. As long as a photovoltaic system has the sun, the battery components will generate electricity, and now all use automatic control numbers, basically without manual operation.
⑤Abundant materials for solar cell production: silicon material is abundant, and the crustal abundance ranks second after oxygen, reaching as much as 26%.
⑥Long service life. Crystalline silicon solar cells have a life span of 25 to 35 years. In the photovoltaic power generation system, as long as the design is reasonable and the selection is appropriate, the battery life can be as long as 10 years.
⑦The solar cell module is simple in structure, small in size and light, easy to transport and install, and has a short construction period.
⑧ System combination is easy. Several solar cell components and battery cells are combined to form the solar cell array and battery pack of the system; the inverter and the controller can also be integrated. The system can be large or small, and can be easily expanded.
The energy recovery period is short, about 0.8-3.0 years; the energy value-added effect is obvious, about 8-30 times.
