Solar Energy

Sun is the ultimate and the natural source of energy for all the available fuels. From thousands year suns ray has been used for providing warmth and serving the purpose of drying. The solar system don not produces air pollutants and they also have the minimum impact on environment. There is quite variation in the amount of sunlight that reaches the earth surface depending on the location, time of day, season of the year and weather conditions. Various solar technologies are there that directly tap the infinite power of sun and which is further used to produce heat, light and power.  There are various Solar techniques such as Passive Solar Lighting and Heating, Solar Water Heating, solar Electricity and Solar Thermal Electricity. Solar Thermal electricity not only provides the heat but also generates the electricity. Solar energy can be converted to electricity in two ways i.e, Photovoltaic and Solar Power Plants. Photovoltaic (PV devices) or “solar cells” that change sunlight directly into electricity. PV systems are often used in remote locations that are not connected to the electric grid.  They are also used to power watches, calculators, and lighted road signs. Solar Power Plants indirectly generate electricity when the heat from solar thermal collectors is used to heat a fluid which produces steam that is used to power generator
