Are: the use of light and heat: It is the solar radiation collected by the interaction with the material to be converted into thermal energy use. The most current solar collection devices, there are flat-plate collectors, vacuum tube collectors and focusing collectors, etc. 3. Solar power: the future of large-scale use of solar energy is used to generate electricity. Use of solar power generation are mainly two ways: ① light - heat - electricity conversion. Namely the use of solar radiation generated by thermal power. Generally is absorbed by solar collectors to heat the working fluid into steam,Solar Lights and then driven by the steam-driven turbine generators. The previous process for the light - heat conversion, after a process of heat - electricity conversion. ② light - electrical conversion. The basic principle is to use photovoltaic effect to convert solar radiation directly into electrical energy, and its basic unit is the solar cell. Photochemical utilization: This is a direct decomposition of water using solar radiation of light hydrogen - chemical conversion. Bioavailability of light: to achieve through photosynthesis to convert solar energy into biomass process. Currently there are fast-growing plants (such as firewood), oil crops, and giant kelp.
Solar water heaters to solar energy into heat energy, heating the water from low temperature to high temperature, to meet people in life, the production of hot water use. Structure divided by the solar water heater vacuum tube solar water heater Peace plate solar water heater, vacuum tube solar water heater is currently dominated, accounting for 95% of domestic market share. Domestic solar water heater vacuum tube solar collector tube by,china Hex Bolt storage tanks and associated annexes, to convert solar energy into heat energy mainly depend on tube. Floating collector tube using hot water cold water sink principle, so that water will reach the required micro-circulation of hot water.
Solar energy, generally refers to the sun's radiant energy, solar energy is a renewable energy, solar energy is a broad number of energy sources on Earth, wind, biomass, tidal energy, water potential, and so on. Basic form of solar energy can be divided into light - thermal, optical - electrical use, light - chemical use, light - bioavailability four categories. Four types of solar energy utilization in the way of light - thermal conversion of the most mature technology, products are up to, relatively low cost. Such as: solar water heaters, water boilers, dryers, solar cookers, solar greenhouse, solar house, solar desalination and solar heating and cooling equipment, etc.. Solar thermal power than photovoltaic solar conversion efficiency is higher but the application is not common. In the solar thermal conversion, the current most widely used,Solar Water Heater the most mature technology, economy is the best application of solar water heaters.
