In the future of light energy, every new industry will experience scandals. Europe's rooftop photovoltaic coverage is much higher than that of China, which is still in its infancy. The 70 square meter, 10 kilowatt power plant produces 11,000 kilowatt hours of electricity per year, offsetting residential electricity consumption (scaled energy consumption of 0.62, 0.65 and 0.91 yuan/kWh, output total electricity is 0.37 yuan/kWh). with a national blocking grant for 20 years. Surplus electricity for self-consumption is sold to the power grid, and the purchase price of the power grid is the same as that of coal-fired electricity, which is currently 0.42 yuan/kWh. On average, this amounts to 1 yuan/degree. Cost recovery takes 8 years and benefits take 25 to 30 years.
The reason there is a scam is that small businesses take advantage of the greed of masses for the cheap, build cheaply, use defective photovoltaic panels, have low energy production and have not promised after-sales service. service. There are even problematic situations where faulty accessories are used to create websites to defraud customers into taking loans to create websites. Therefore, don't be greedy for cheap when building a website. There is absolutely a difference between an apple worth 500 yuan and an apple worth 5,000 yuan. Choose large companies, especially companies with public assets and government records. After all, the photovoltaic after-sales warranty can reach 20 years.
At present, photovoltaic power plants distributed on household roofs have a high photovoltaic level. coverage in Jiangsu and Guangdong, and companiesSummers of power plants have mature technology. The first roofs have been in service for more than 5 years
