Solar Panel Technology Explained

Solar cells are made primarily from silicon a chemical element with conductive properties.

Solar panel technology explained.

Photo voltaic cells use sunlight as a source of energy and generate direct current electricity. A pv module is an assembly of photo voltaic cells mounted in a framework for installation. Simply put a solar panel works by allowing photons or particles of light to knock electrons free from atoms generating a flow of electricity. Arrays of a photovoltaic system supply solar electricity to electrical equipment.

Solar photovoltaic systems convert. The most common application of solar energy collection outside agriculture i. Collecting and using solar thermal heat energy. How efficient are solar panels.

Old school solar technology uses large crystals made out of silicon which produces an electrical current when struck by light. The term solar panel is used colloquially for a photo voltaic module. While scientists are working hard at improving efficiency and have achieved impressive results in the laboratory the best commercially available panels are the sunpower x 22 series panels. A collection of pv modules is called a pv panel and a system of panels is an array.

Concentrated solar power csp on the other hand uses mirrors to direct sunlight or solar thermal energy onto a small receiver. Solar explained energy from the sun. Companies can choose between two forms of concentrated solar technology. Advantages of solar energy.

Solar panel efficiency is a measure of how well a panel converts sunlight to electricity. Silicon can do this because the electrons in the crystal get up and. Exposure to light changes silicon s electrical characteristics which generates an electric current. The sun has produced energy for billions of years and is the ultimate source for all of the energy.

Solar panels actually comprise many smaller units. Modern solar panels are made from silicon solar cells which are either monocrystalline or polycrystalline sometimes called multicrystalline silicon solar cells. The solar panel with the highest watt is the sunpower e series a commercial solar panel line. The top panel in the e series comes out at a whopping 435 watts.

Solar panels heat up water with the energy from the sun and then returns that warm water into the tank. An example of an early solar energy collection device is the solar. Concentrated photovoltaics cpv uses mirrors or lenses to focus sunlight onto a small area of solar cells creating electricity. A cell is a small square of silicon about 6 x 6 with electrical contact plates on the face.
