Solar energy is the transformation of heat, the energy that comes from the sun.It has been used for thousands of years in many different ways by people all over the world. Solar energy is the technology used to harness the sun's energy and make it useable. Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV), indirectly using concentrated solar power, or a combination.Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight into a small beam. As the electrons flow through the cell, they generate electricity. Another technique uses moveable mirrors to focus the sun's rays on a collector tower, where a receiver sits. This heat is then transferred to the water running through your home’s piping so you don’t have to rely on traditional water heating methods, such as water heaters powered with oil or gas. Space engineers include solar panels on satellites to produce the energy needed to run their electric circuits. For example, big windows placed on the sunny side of a building allow sunlight to heat-absorbent materials on the floor and walls. See more. Solar is a clean, renewable energy resource, and figures to play an important part in the global energy future.
