Solar power generation principle of what is a solar energy street light company

Now the country's increasingly advocated the concept of energy conservation and environmental protection, solar energy here is very good use of it, so what is solar power? What type is it? Through water or other medium and device to convert solar radiation into electricity generating way,


now the country increasingly advocated the concept of energy saving and environmental protection, got very good use of solar energy, solar power is what? What type is it? Solar thermal power generation is a kind of work by water or other medium and device convert solar energy into electrical energy power generation method. First of all, the solar energy is converted into heat energy, the heat energy into electrical energy. There are two kinds of transformation patterns: one is the solar thermal energy directly into electricity, such as semiconductor or metal materials thermoelectric power generation, vacuum device and thermoelectric power generation, alkali metal thermoelectric conversion and MHD power generation. Another way is through the engine ( Such as steam turbine) Drive the generator using solar power, it similar to the traditional thermal, just heat energy comes not from the fuel, but from solar energy. There are different types of solar thermal power generation, basically has the following five kinds: tower system, groove system, disk systems, solar pool and solar tower thermal power generation. The first three is concentrated solar thermal power generation system, the latter two are focusing system. Some developed countries will solar thermal power generation technology as a key national research and development, has built dozens of various types of solar thermal power generation demonstration plants, reached the practical application of grid power level. At present, the world's most promising solar thermal power generation system can be roughly divided into the groove parabolic concentrator system, the central receiver or solar tower condenser and disc parabolic concentrator system. Three is technically and economically viable form: 30 ~ 80 mw condensing parabolic trough type solar thermal power generation technology ( Parabolic trough) ； 30 ~ 200 mw point focusing centralized receiving solar thermal power generation technology ( Hereinafter referred to as the centralized receiving) ； 7. 5 ~ 25 kw point focusing parabolic dish solar thermal power generation technology ( Parabolic dishes) 。 Concentrated solar thermal power generation system of the main heat transfer working medium is water, steam, molten salt, etc. The heat transfer working medium can be heated to 450 degrees Celsius in the receiver, and then used to generate electricity. In addition, the power mode of regenerative energy can temporarily store for a couple of hours to meet peak demand. Parabolic trough focusing system using parabolic cylindrical tank firing mirrors to collect sunlight on a tubular receiver, and heating tube of the heat transfer working medium to generate steam in the heat exchanger, so as to promote the traditional steam turbines. Solar thermal power generation system using a set of independent tower heliostat tracking the sun, the sun gathered on the fixed tower building at the top of the receiver, to produce high temperature. In addition to the above several traditional methods of solar thermal, solar chimney power generation and solar pool power generation such as new areas of research have made progress.
