Solar Energy is, simply, energy provided by the sun. This energy is in the form of solar radiation, which makes the production of elecricity possibleSo how is electricity produced using Solar Energy? Basically, it can be produced directly from photovoltaic, PV, cells.( Photovoltaic literally means "light" and "electric".) These cells are made from materials which exhibit the "Photovoltaic effect" i.e., when sunshine hits the PV cell, the photons of light excite the electrons in a cell and cause them to flow, generating electricity. Interesting isn't it?
