Solar is the fastest growing energy
source in the world, and for good reason. It offers a limitless supply of
clean, safe, renewable energy for heat and power. Considering the
fact that the Earth receives more energy from the sun in just one hour than the world
uses in a whole year it is easy to understand why solar energy sources are a

technologies has decreased, solar is moving into the mainstream and growing
worldwide at 40-50% annually.
There are currently three primary
solar technologies:
