What is Solar PV?
A solar photovoltaic panel is made up of several layers of semi-conducting material. This material is most commonly silicon. When light shines onto the material, a flow of electricity is created. Solar Panels do not need direct sunlight to produce energy. Systems can produce electricity during the Winter months and on cloudy days. The amount of electricity a panel can produce is determined by the strength of the UV light, (sunshine).
Solar radiation is light, otherwise known as electromagnetic radiation. This radiation is emitted by the sun. Every place on Earth encounters a level of sunlight throughout the year, but the level differs based on the location. Some areas on Earth receive more solar radiation than others. Solar photovoltaic panels absorb the solar radiation and turn it into usable energy.
“The amount of sunlight that strikes the earth’s surface in an hour and a half is enough to handle the entire world’s energy consumption for a full year.” – Solar Energy Technology Office
