Solar Energy

SOLAR ENERGY solar faculty is the most pronto open and free source of capacity since prehistoric times. It is estimated that solar brawniness equivalent to over 15,000 times the worlds annual commercial elan vital consumption reaches the earth every year. The surface of the earth receives to the highest period 1014 kW from sun in the form of solar capacity which is approximately five assigns of magnitude greater than that currently be consumed from all resources. It is evident that sun will last for 1011 years. India receives solar competency in the region of 5 to 7 kWh/m2 for three hundred to 330 days in a year. This energy is sufficient to generate up 20 MW solar power plant per finalise kilometre land heavens. Solar energy digest be utilized through devil different r unwrapes, as solar thermic route and solar electric (solar photovoltaic) routes. Solar thermal route practises the suns heat to produce hot weewee supply or a ir, cook food, drying materials etc. Solar photovoltaic uses suns heat to produce electricity for discharge home and building, trial motors, pumps, electric appliances, and lighting. There are deuce obvious obstacles to harnessing solar energy. Firstly it is not constantly forthcoming on earth. then some form of storage is compulsory to sustain solar energy through the night and during wet season. Secondly the solar energy is diffused.

Although the total amount of energy is enormous, the collection and preservation of solar energy into useful forms must(prenominal) be carried out over a large area which entails large neat investment s. . SOLAR WATER HEATING ! By using solar radiation, water system or any unruffled can be alter by using a solar aggregator. Such systems can provide hot water for different applications in industries outright or as boiler feed and also in hostels, hotels and canteens. There are two types of solar storage batterys in use: 1. Flat coat collector 2. parabolic or concentrating collector Flat plate collector: The absorber plate is metallic.
