What is a solar thermal power Solar thermal power generation is a new type of solar power generation, solar power we have said before, generally refers to photovoltaic power generation, are two different ways. In other words, solar power is now in two ways, namely thermal power and photovoltaic power generation, its operating principle and scope of use has a greater difference. Focus on solar thermal power generation is also called solar thermal power, and photovoltaic power generation is not the same, it is put through a variety of physically gathered solar direct light and produce high temperature and pressure steam, steam-driven turbines to generate electricity. Based collectors in different ways, can be divided into solar trough thermal power, solar thermal power and solar tower thermal power disc three. Solar thermal power and photovoltaic power generation principle difference between the first and the device is not the same. Thermal power is driven by the steam turbine power generation and solar heat collector, and a heat transfer means of electricity, the most important component is the collector or devices; which is the use of semiconductor photovoltaic photovoltaic effect to convert sunlight directly into electricity , the basic components used in solar panels, the way the optical power transfer. Followed by the use of different. Solar thermal power emitted with conventional thermoelectric power, hydropower has a better fit, suitable for large-scale development. In addition, the thermal power generation due to the more demanding lighting conditions, so good lighting conditions more suitable areas. The photovoltaic power generation device is relatively simple, the illumination requirements are relatively low, is more suitable for miniaturization, and therefore more suitable for distributed use. Again, in the specific application, the PV industry has been formed, the use of technology is more mature, suitable for large-scale promotion use. The thermal power generation is still mainly in the research and demonstration phase, the cost is very high level, large-scale use will take time. Recently, China's first solar thermal power plant successfully generate electricity, which is a national investment and construction. Therefore, at present, the average family in the choice of solar power system does not have to consider solar thermal power generation.
