Harnessing the sun light and heat

Harnessing the sun light and heat

The radiant light and heat obtained from the sun is called solar energy. Solar energy uses captured sunlight to create photovoltaic power or concentrated solar power for solar heating. In 1839 a French physicist, A.E.Becquerel discovered photovoltaic effect, which is a physical and chemical phenomenon through which voltage and electric current is generated in a material upon exposure of light. Solar-powered photovoltaic panels convert the sun’s rays into electricity by electrons in silicon cells using the photons of light from the sun. The noticeable advantages are that solar power is a renewable free and pollution free source of energy. OYLA gives a vivid idea on the uses of the renewable, inexhaustible and affordable form of solar energy.
