Power from the sun – clean and unlimited

Solar Energy: The ultimate energy source

It provides the earth with light, heat and radiation. Every hour the sun radiates onto the Earth more than enough energy to satisfy global energy needs for an entire year.

When sun’s energy is harnessed and made useable it is called solar energy. While many technologies derive fuel from one or the other from form of solar energy, there are also technologies that directly transform the sun’s energy into electricity.

Solar energy is our earth’s core source of renewable energy since generating electricity directly from sunlight does not deplete any of the earth’s natural resources and supplies the earth with energy continuously.

Solar energy generating electricity

Photovoltaic devices produce electricity when sunlight strikes them. Electricity generation relies upon chemical. When sunlight strikes a PV cell, chemical reactions release electrons, thus generating electric current. Using PV is a cheaper option than new electric lines for providing power to remote locations.

Solar Power Plants – generates electricity when the heat from solar thermal collectors is used to heat a fluid to produces steam that is used for power generation. Use the sun’s heat to generate steam to drive an electric generator.
