ELECTRICITY VIA NATURAL SOURCES – SOLAR AND WIND ENERGY
SOLAR ENERGY:
INTRODUCTION –HISTORY AND DEVELOPMENT
As we all know that, history of solar energy is as old as the humans. Since last two centuries human beings started to use it in order to generate electricity. We get electricity form the sun, directly by some simplest processes or else we can get it without any processes too. ‘Many materials produce small amount of electricity when they are exposed to the light’ – this was discovered by Alexandre Edmond Becquerel in 1839. Photovoltaic (PV) converts sunlight into electricity. Sunlight based power is apparently the cleanest, most dependable type of renewable energy accessible, and it can be utilized as a part of a few structures to control your home. Sun powered controlled photovoltaic (PV) boards change over the sun 's beams into power by energizing electrons in silicon cells utilizing the photons of light from the sun. This power can then be utilized to supply renewable energy to our homes. Solar panels are the devices that convert light to electric energy, which are called "solar" panels. The powerful source of light is available from the Sunlight, which are called Sol in technical world.
Solar electricity is a reusable form of energy. Solar panels are called as modules which contain photovoltaic cells, which are made up of silicon that emits incoming sunlight into electricity instead of heat. According to the recent studies from the World Energy Council,
