Solar photovoltaic is a renewable energy source
Renewable energy source
Solar PV systems convert light into electrical power. They range in size from a few square centimetres, for example on calculators and watches to systems of hundreds of square metres made from interconnected modules that form an array. Photons in sunlight hit the solar panel and are absorbed by semiconducting materials, such as silicon. Electrons (negatively charged) are knocked loose from their atoms, allowing them to flow through the material to produce electricity. Due to the special composition of solar cells, the electrons are only allowed to move in a single direction. An array of solar cells converts solar energy into a usable amount of direct current (DC). The DC is carried through wiring to an inverter, which converts the current to mains AC (alternating current) which is connected to the property’s main electricity supply.
