Solar Energy - A clean and green energy source for today’s world.
Photovoltaic cells are increasing in efficiency, but decreasing in cost although they are still the same old black squares placed on solar panels in an array format, but now they are able to concentrate energy to a particular point in a much better manner. The size of the cells is decreasing as their efficiency rises, meaning that each cell becomes cheaper to produce and at once more productive. Today, it takes us just about to produce one watt of energy from the sun in an hour. ...
