Energy from the sun can be categorized in two ways:
(1) in the form of heat (or thermal energy)
(2) in the form of light energy
Solar thermal technologies use the sun’s heat energy to heat substances (such as water or air) for applications such as space heating, pool heating and water heating for homes and businesses.
There are a variety of products on the market that utilize thermal energy.
The sun’s light can also be used to produce electricity on a large utility-scale by converting the sun’s light into electricity. Which can be used to run Lights, Fans, Water Pumps and Home Appliances etc.
