Solar energy is a form of light that emit from the sun. That has been used by people since ancient times by using a range of power-packed technologies. Solar energy and it uses are numerous to humans. So People started to use the solar energy system every day in various ways. There are a many different products are available in the market that uses solar thermal energy for working. Let us see how the solar energy has been used in our day-to-day life. When we hang clothes outside to dry in the sun, we are using the solar heat to dry our clothes. Plants has been well used the solar light to make food.

Animals eat plants for food. Solar energy from the sun can be separated in two ways: (1) in the form of heat (or thermal energy), and (2) in the form of light energy. Usually solar thermal technologies uses the solar heat energy to heat substances like water or air for space heating, pool heating, water heating, air heating, cooking & drying, steam generation, distillation, etc to homes commercial, industrial and businesses applications. In addition, the solar heat can be further used to produce electricity by converting solar energy into mechanical energy.

So the sun is most responsible for all forms of energy. It is reported that the sunrays emitted from the sun takes about 9 minutes to reach the Earth. The Solar Home Lighting system is well designed for domestic purposes. Those are powered by solar energy by using solar cells and convert solar energy i.e., sunlight directly to form electricity. The electricity is stored in batteries that can be used for the purpose of lighting whenever need.
