The Sun should be considered as the use of solar heat as well as light.
● Solar thermal Water heaters renewable Energy (natural energy) is a representative of solar power that utilizes solar light. The system which buys the whole amount of power obtained from there becomes a tail wind, and the solar power generation rapidly spread and expanded in recent years. Solar power will continue to run as a top runner in renewable energy. The energy use using the heat of the sun is attracting attention to the method of electric conversion of this solar light again. The solar heat is collected by the collector, etc., and it tries to use it as a heat source of hot water and heating.
● For example, when used in hot water, energy conversion efficiency (heat collection efficiency) is 40% or more, and has a much higher power than the conversion efficiency of 10% solar light. If the use facility is hot water in the possibility of increasing the solar water heater, it is the one that the hot water of 60 ℃ or more can be obtained in summer. A standard solar water heater (6 ㎡ of heat collector area and 300L) can reduce the energy consumed by the general household in hot water for one year by about 95% (approximately 455L in terms of kerosene). The office which uses electricity and kerosene, etc. To change water to hot water if it thinks is not a little. The golf course, the sports facilities, the geriatric care facilities, etc. are used for the hot water in the bath, the shower, and the hot water etc., and are overwhelmingly more than energy consumption such as other lights and air conditioners. In other words, the solar water heater is energy-saving, and energy costs are reduced.
