Solar power plants solar power plants are devices that use solar modules to convert light energy into electricity, which is a clean and renewable source of energy for the earth.
The French Audejo solar power station was the world's first solar power station to achieve solar power. Although the power generation was only 64 kilowatts at the time, it laid the foundation for later research and design of solar power plants. 1982 the United States completed a 10-megawatt tower solar thermal intermediate test power station. The United States plans to have a total installed capacity of 40 million kilowatts of solar power plants by 2008.
The percentage of total energy produced in 2008 and 2020 will be 7% and 25%. Because the solar thermal converter (concentrator) needs to occupy a large space to harvest light and heat, the equipment is on the large side, to the United States in California plans to build a 10,000 kilowatts of power generation equipment, for example, the light collection device up to 400,000 square meters, 2 million kilowatts, it is necessary to cover an area of 50 square kilometers.
Large solar power plant efficiency is only about 30%. In addition, solar power stations also need to have to cope with the night and cloudy days with electricity needs of the accumulator, and the required concentrator cost is also more expensive, poor economic power generation, therefore, affect the widespread promotion and application.
