Compared with other energy utilization technologies, solar power generation has its incomparable advantages, mainly in the following aspects:
solar energy resources are not in danger of exhaustion, and the resources are widely distributed and subject to small geographical restrictions
silicon, the main material of solar cells, is rich in raw materials; No mechanical rotating parts, no noise, good stability
simple maintenance and low maintenance cost
the system is a component, which can be quickly installed anywhere, without pollution, and completely clean (except the battery)< At the same time, solar power generation also has its shortcomings:
the energy distribution density of solar irradiation is small, about 100 W / m2
the annual power generation hours are relatively low, with an average of 1300 hours
it can't generate electricity continuously, which is greatly affected by weather conditions such as season, day and night, cloudy and sunny
it is difficult to accurately predict the power generation of the system
the cost of photovoltaic system is still relatively high, the system cost is 40000-60000 yuan / kW
the reason for the scam is that small companies take advantage of the characteristics of the masses' greed for cheap, build at a low price, use inferior photovoltaic panels, generate low power, and promise no after-sales service. There are even bad cases of using inferior accessories to build a station to defraud customers of loans. So don't be greedy for cheap, 500 yuan apple and 5000 yuan apple is absolutely different. Choose large companies, especially those with state-owned assets and government background, after all, the photovoltaic after-sales guarantee has been up to 20 years
at present, the photovoltaic coverage rate of Jiangsu and Guangdong is high, and the technology of power station enterprises is mature. The first batch of roofs have been in operation for more than five years
