solar energy summary | Britannica

Solar energy is inexhaustible and nonpolluting, but there is inherent inefficiency in converting light to electricity. In the 21st century solar energy is expected to become increasingly attractive as a renewable energy source and as a useful tool in the fight against anthropogenic global warming.

How Do Solar Panels Work? Solar Power Explained

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. The heat is transferred to a "transfer fluid" (either antifreeze or potable water

Buying a solar energy system makes you eligible for the Solar Investment Tax Credit, or ITC. In December 2020, Congress passed an extension of the ITC, which provides a 26% tax credit for systems installed in 2020-2022, and 22% for systems installed in 2023. The tax credit expires starting in 2024 unless Congress renews it.

Solar explained Photovoltaics and electricity

Photovoltaic cells convert sunlight into electricity. A photovoltaic (PV) cell, commonly called a solar cell, is a nonmechanical device that converts sunlight directly into electricity.Some PV cells can convert artificial light into electricity. Sunlight is composed of photons, or particles of solar energy.These photons contain varying amounts of energy that correspond to the different

Solar Energy

Solar energy is the radiant light and heat from the sun that has been harnessed by humans since ancient times using a range of ever-evolving technologies.
