Solar Flat Plate Collectors
Solar energy is the most viable source of power, which is gaining popularity by the day. Heating the water using the solar energy is one the most efficient utilization of solar power. Basically, in solar heating systems there are solar flat plate collectors and storage tanks to store the thermal water. Solar flat plate collectors are one of the types of solar collectors that are used to absorb and intercept the sunís radiations for water heating. Thermal water obtained using the solar flat plate collectors is generally used in the hotels, businesses, homes, swimming pools, under floor heating, etc.
Solar flat plate collectors are the solar thermal collectors that consist of an insulated and weatherproof box, which has a black metal absorber sheet and built in pipes where the water is present. The water inside the pipes gets heated up by the solar energy and by natural convection the water circulates through the system. There are chiefly two types of solar heating - active and passive. In passive solar water heating, the hot water from the solar collectors gets transferred to the storage tanks through means of gravity. The motion of water is slow compared to the demand of the water supply. But when there are some electrical pumps attached in the system to push the thermal water from the collector pipes to the storage tanks then it becomes an active solar heating system.
Solar flat plate collectors are varied in design but mainly all of them contain a flat-plate collector, a transparent cover and a heat transport fluid (generally water or an antifreeze fluid). Flat-plate collector absorbs the sunrays and the transparent cover lets the solar energy to pass through reducing the heat loss from the absorber. The heat transport fluid that circulates in the pipes affixed to the collector removes the heat from the absorber and heats the water, which is then transferred to the storage tanks. Solar flat plate collectors, best suit the demand of places where the required water temperature ranges 30 degree to 70 degrees. Solar flat plate collectors are the best alternative to the conventional geysers used in the winters to heat the water. The electricity consumption that reaches its peak using the power-grid geysers can be cut back to 20% consumption with the installation of solar flat plate collectors in any household. The Solar flat plate collectors are now designed very diligently for areas where freezing is a possibility. They are plumbed in such a way that the water gets drained down completely using gravity, so that their cracking doesnít happen due to freezing.
Solar flat plate collectors are being installed everywhere nowadays because of their utilitarian aspect as well as their economical aspect. They donít use grid-tied power, and hence, donít cause any wastage of the natural resources. Solar flat plate collectors work on free solar power and are thus aiding the prevention of global warming. Solar flat plate collectors utilize the solar power optimally to heat the water and hence meet all the needs of humans all year round. Solar Panels in India and solar flat plate collectors are available in various cities and can easily be exported to different countries.
