It is fully renewable with few environmental impacts, and the cheapest source of electricity in many countries.
READ MORESolar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation. This energy can be used to generate electricity or be stored in batteries or thermal storage. Below, you can find resources and information on the basics of solar radiation, photovoltaic and
READ MORESolar thermal (heat) energy is a carbon-free, renewable alternative to the power we generate with fossil fuels like coal and gas. This isn''t a thing of the future, either. Between 1984 and 1991, the United States built nine
READ MORESolar collectors and thermal energy storage components are the two kernel subsystems in solar thermal applications. Solar collectors need to have good optical performance (absorbing as much heat as possible) [3], whilst the thermal storage subsystems require high thermal storage density (small volume and low construction
