PV systems generate electricity when photovoltaic panels capture solar energy and convert it into DC electricity. Thermal systems capture the sun’s heat through thermal panels that absorb the sun’s thermal energy and transmit it to a heat-transfer fluid. In this article, you’ll learn: Which system is best for your energy needs.
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 technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation.
A solar thermal system generates electricity indirectly by capturing the heat of the sun to produce steam, which runs a turbine that produces electricity. A solar photovoltaic system produces electricity directly from the sun’s light through a series of physical and chemical reactions known as the photovoltaic effect.
Solar energy is the light and heat that come from the sun. To understand how it's produced, let's start with the smallest form of solar energy: the photon. Photons are waves and particles that are created in the sun's core (the hottest part of the sun) through a process called nuclear fusion.
Instead, the solar panels, known as "collectors," transform solar energy into heat. Sunlight passes through a collector's glass covering, striking a component called an absorber plate, which has a coating designed to capture solar energy and convert it to heat.
Solar photovoltaic cells are grouped in panels, and panels can be grouped into arrays of different sizes to power water pumps, power individual homes, or provide utility-scale electricity generation. Source: National Renewable Energy Laboratory (copyrighted)
