Solar power generation There are two methods of solar power generation, solar panel one is the light-thermal-electric conversion method, and the other is the light-electric direct conversion method. The photo-thermal-electric conversion method uses the thermal energy generated by solar radiation to generate electricity. Generally, solar panel the solar collector converts the absorbed thermal energy into the vapor of the working fluid, solar panel and then drives the steam turbine to generate electricity. The former process is a light-heat conversion process;solar panel the latter process is a heat-electric conversion process, solar panel which is the same as ordinary thermal power generation.
The disadvantage of solar thermal power generation is its low efficiency and high cost. It is estimated that its investment is at least 5-10 times more expensive than ordinary thermal power stations. A 1000MW solar thermal power station requires an investment of US$2~2.5 billion, solar panel and the average investment of 1kW is US$2000~2500. Therefore, solar panel it is suitable for small-scale special occasions, solar panel and large-scale utilization is economically uneconomical, solar panel and it cannot compete with ordinary thermal or nuclear power plants.
