Advantages of solar photovoltaic power generationsolar street light-litelsolar manufacturers

Solar photovoltaic power generation has many advantages. It directly converts solar energy into electricity, does not consume fuel, does not pollute the environment, does not generate noise, and does not produce radiation that endangers human safety. It is a green and clean energy source. Solar energy resources are widely distributed and are inexhaustible and inexhaustible resources. Compared with traditional thermal power generation and new wind power generation and nuclear power generation, solar power generation is the most ideal sustainable renewable energy power generation technology. 1. The sun's resources are widely distributed: inexhaustible and inexhaustible solar energy is the energy generated by the continuous nuclear fusion reaction process inside the sun, although the energy radiated by the sun to the outside of the earth's atmosphere is only its total radiant energy (about 3.75 ×10^14tw), but its radiation flux is as high as 1.73 × 10^5tw, that is, the energy projected by the sun to the earth per second is equivalent to 5.9 × 10^6 tons of coal. The amount of solar energy hitting the Earth is 6,000 times greater than what humans currently consume. Moreover, solar energy is widely distributed on the earth. As long as there is light, the solar power generation system can be used, and it is not limited by factors such as region and altitude. 2. The rooftop photovoltaic power station avoids the loss caused by long-distance power transmission. Solar energy resources are available everywhere, and can supply power nearby without long-distance transmission, avoiding the power loss caused by long-distance transmission lines. 3. Roof photovoltaic power generation conversion process is simple Roof photovoltaic power generation is a direct conversion from light energy to electrical energy, there is no intermediate process (such as thermal energy conversion into mechanical energy, mechanical energy into electromagnetic energy, etc.) and mechanical movement, there is no mechanical wear. According to thermodynamic analysis, solar power generation has a high theoretical power generation efficiency, which can reach more than 80%, and has great potential for technological development. 4. Roof photovoltaic power generation is clean and environmentally friendly Roof 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 produce noise, does not produce vibration pollution, and does not produce radiation that is harmful to human health. It will not suffer the impact of energy crisis or unstable fuel market, and it is a new type of renewable energy that is truly green and environmentally friendly. 5. Roof photovoltaic power generation system is stable and reliable, and the life of crystalline silicon solar cells can be as long as 20 to 35 years. In the solar power generation system, as long as the design is reasonable and the selection is appropriate, the service life is long (more than 30 years). 6. The rooftop photovoltaic power station does not need special personnel to be on duty. The rooftop photovoltaic power station has no mechanical transmission parts for power generation, and is easy to operate and maintain, and the operation is stable and reliable. A set of solar power generation system can generate electricity as long as there are solar cell components, and the extensive use of automatic control technology realizes unattended operation and low maintenance cost. 7. Roof photovoltaic power station is easy to transport and install. The solar cell module has a simple structure, small size and light weight, which is easy to transport and install. The solar power generation system has a short construction period, and can be large or small according to the power load capacity, which is convenient and flexible, and can be easily combined and expanded. 8. National policy support In terms of subsidies, household photovoltaic power stations can receive a national subsidy of 0.42 yuan per kilowatt-hour of electricity for 20 years. In addition, various localities also have corresponding subsidy policies, such as Foshan subsidy of 0.15 yuan/kWh, subsidy for 3 years; Dongguan subsidy of 0.3 yuan/kWh, subsidy for 5 years. Because the rooftop photovoltaic power station does not occupy the existing land and makes full use of the idle resources of the building, it has received strong support from the national policy. 9. Investment and wealth management income The installation of photovoltaic power plants on the roof not only has the effect of heat insulation and cooling, but also can create green income, preserve the value of your own roof, and at the same time play a green and environmental protection role. With the strong support of the country With the rapid development of the photovoltaic industry, photovoltaic power plants will also become standard and become a well-known financial product. As a typical example of low risk and high return, solar photovoltaic power station has an annual income of about 15% due to the support of national policies and local government subsidies, which is indeed a very suitable investment method for residents with roofs!
