Advantages and functions of solar energy
Second: the earth, no matter where there is solar energy can be in situ development and utilization, there is no transport problem, especially for trafficunderdeveloped rural areas, islands and remote areas had more use value. Third: solar energy is a kind of clean energy. In the development and use, does not produce waste residue, waste water and gas, also there is no noise, but will not affect the ecological balance. Absolutely not cause pollution and pollution.
The advantages of solar energy: solar energy as a new energy, compared with conventional energy it has three major characteristics: first, it is the most abundant energy source. It is estimated that in the past 1 billion 100 million years, the sun itself consumes energy in the future 2%. is sufficient to supply earth, using billions of years it is inexhaustible, inexhaustible.
The technical field of solar energy utilization: only use solar energy there are three major technology areas, namely solar thermal conversion, conversion and optical shop in addition, photochemical conversion, and energy storage technology. The solar photoelectric conversion, mainly various types of solar panels and solar cell power supply system is to convert sunlight directly into electricity a device can the photoelectric efficiency of the solar cell is about 10-14% and its products are the main types of monocrystalline silicon, polycrystalline silicon and amorphous silicon. The domestic product (of a photoelectric device full cost) the price is about 60-80% yuan / Watt Peak. The scope of application of solar cell is very wide. Such as satellites, unmanned weather station, communication station, television relay station the sun, clock, electric poles, black lights, navigation lights, railway signal lights. Solar thermal conversion technology. Most of the products such as water heaters, boiling water heaters, dryers, refrigeration and heating, greenhouse and solar house, Solar range and high temperature furnace, seawater desalination device, water pump, thermal power generation device and solar energy medical appliance
