Several main technologies of utilizing solar energy is introduced

Solar energy is one of the most abundant of human can make use of energy, is also a kind of clean energy, in the development and utilization, won't produce waste residues, waste water, waste gas, no noise, more will not affect the ecological balance, absolutely will not cause pollution and pollution. No matter where on earth have a solar energy, can be on the development and utilization, there is no transport problem, especially for traffic underdeveloped rural areas, islands and remote areas had more use value.

the human use of solar energy has several big technology, namely the solar-thermal conversion, optical shop and light conversion, in addition, there are energy storage technology.

the sun most solar-thermal conversion technology products. Such as solar street lights, solar water heater, water boiler, dryer, heating and refrigeration, greenhouse and the sun room, solar oven and high temperature furnace, seawater desalination device, water pump, and solar thermal power generation device medical apparatus.

the sun photoelectric conversion, mainly all kinds of types of solar panels and the power supply system.

solar cell is a device converts sunlight directly into electricity.

the photoelectric efficiency of solar cell is about 10 - 14%, its products mainly include monocrystalline silicon, polycrystalline silicon and amorphous silicon. Domestic product ( The full cost refers to the photoelectric device) About 60 - price 80% yuan/peak.

the sun battery application range is very wide. Such as satellites, unmanned stations, stations, television relay station, sun clock, electric poles, black light lamp, beacon light, railway signals.

the sun chemical transformations include photosynthesis, photoelectrochemical effect, photosensitive chemical action, and light decomposition reaction, this technology is still in the phase of experiment research.
