Superiority analysis of rooftop photovoltaic power generation / 2017/5/25 14:14:09

Power generation is the direct conversion of solar energy into electrical energy. It does not consume fuel, does not pollute the environment, does not produce noise, and does not produce radiation harmful to human health. It is a green clean energy. Solar energy resources are widely distributed and are inexhaustible and inexhaustible resources. Compared with the traditional thermal power generation and wind power generation, new nuclear power, solar power is the most ideal sustainable renewable energy power generation technology, its advantages are as follows:
1, the solar resources are widely distributed, inexhaustible and inexhaustible
Solar energy is a nuclear fusion reaction process produces the solar interior continuous energy solar radiation to the earth's atmosphere, although the external energy is only the total radiant energy (about 3.75 x 10^14tw) of 2 billion 200 million, but the radiation flux has been as high as 1.73 * 10^5tw, namely the sun every second is projected onto the earth's energy is 5.9 x 10^6 tons of coal. Solar energy to the earth is 6000 times larger than the energy consumed by man today. And solar energy is widely distributed on the earth, as long as there is bright place, you can use solar power generation system, free from geographical, altitude and other factors.
2, rooftop photovoltaic power station to avoid the loss caused by long-distance transmission
Solar energy resources can be obtained everywhere and can be supplied nearby, without long distance transportation, so as to avoid the power loss caused by long distance transmission lines.
3, the roof photovoltaic power conversion process is simple
[rooftop photovoltaic] power generation is directly from light energy to power conversion, there is no intermediate process (such as thermal energy conversion to mechanical energy, mechanical energy conversion to electromagnetic energy, etc.) and mechanical movement, there is no mechanical wear and tear. According to thermodynamic analysis, solar power generation has a high theoretical efficiency of power generation, reaching more than 80%, and the potential for technological development is enormous.
4, rooftop photovoltaic power generation, clean and environmental protection
The roof of photovoltaic power generation itself does not use fuel, not any emissions of greenhouse gases and other substances including exhaust gas, no air pollution, no noise, no vibration pollution, no harmful radiation to human health. Will not suffer from energy crisis or fuel market instability caused by the impact of the real green is a new type of renewable energy sources.
