My home is sometimes not as high as the temperature as long as the sun is enough hot water heater, and sometimes it is very hot, but if the cloudy and the like will not be how hot, solar energy is used for light?
5, the domestic solar energy utilization is mainly thermal (mainly solar water heater as the representative), followed by photovoltaic (solar street lights, etc.), but in Japan, the use of solar energy is mainly through photovoltaic power generation
4, thermal power generation, photovoltaic power generation can, but the cost is very high, and the conversion efficiency is very low (about four dollars per kilowatt), there is a thermal power generation technology is not very mature, is the first light energy is converted to heat, then into electricity, for now still less.
3, the use of photovoltaic is a photovoltaic power generation, mainly by the photoelectric board (monocrystalline silicon or silicon silicon) will be converted into electricity energy stored in the battery, or directly by the use of electrical appliances
1, as long as the use of solar energy as long as the use of solar thermal and photovoltaic;2, is the so-called photothermal convert solar energy into heat, then heat transfer to the working fluid (water, air, or other material, working fluid of the solar water heater is in use, water) is mainly composed of a solar collector in the sunlight, the light energy is converted into heat energy.
