Man is always searching for new sources of energy. The sun gives out vast amounts of energy, of which only a tiny fraction reaches the Earth. If only this small part of energy is used, it would meet the world’s need of power.
Solar panels are used to harness the sun’s power. These panels are attached to the roof tops of houses to absorb the sun’s energy, used for heating domestic water supplies. In 1969, at Odeillo in France, the first solar power station was built. These power stations use solar power to generate energy and the solar panels are used to collect as much energy from the sun as possible.
Below Solar Panel info from Wikipedia (Read More):-
A photovoltaic module or photovoltaic panel is a packaged interconnected assembly of photovoltaic cells, also known as solar cells. The photovoltaic module, known more commonly as the solar panel, is then used as a component in a larger photovoltaic system to offer electricity for commercial and residential applications.
