Solar thermal energy is a technology used for harnessing solar power for practical applications, from solar heating to electrical power generation. Solar thermal energy is the heat that can be gathered from solar power without the use of photoelectric cells. Solar power plants generate electricity by converting solar energy to heat. It is a form of energy that can be transferred into water and stored in insulated containers and kept heated constantly by the sun, while retaining energy overnight. Imagine getting an inexhaustible supply of hot water and household heating for free without damaging the environment. This is one of the most costeffective renewable energy systems and can significantly reduce your utility bill.
