How do active solar energy systems work?

Active solar energy systems use solar energy to heat a liquid through mechanical and electric equipment to collect and store the energy captured from the sun. Photovoltaic solar cells capture light energy from the sun and transform it directly into electrical energy. Their use is limited by the availability of sunlight. Created by Khan Academy.

What are the basics of solar energy technology?

Learn solar energy technology basics: solar radiation, photovoltaics (PV), concentrating solar-thermal power (CSP), grid integration, and soft costs.

How does solar work?

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.

Do you know about solar energy?

This video gives a simple but compelling introduction to solar energy. Did you know that all of the energy we use comes from the sun,? You probably know that’s true for solar panels, but the sun is also the ultimate source for energy generated by wind, water, and fossil fuels. Watch thi Show more

What are active and passive solar technologies?

The methods use either active solar energy or passive solar energy. Active solar technologies use electrical or mechanical devices to actively convert solar energy into another form of energy, most often heat or electricity. Passive solar technologies do not use any external devices.
