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 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.

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 solar energy systems & how do they work?

Solar energy systems come in all shapes and sizes. Residential systems are found on rooftops across the United States, and businesses are also opting to install solar panels. Utilities, too, are building large solar power plants to provide energy to all customers connected to the grid.

Do solar panels generate electricity at night?

Solar panels generate no electricity at night time. Solar panels can't store energy, so you have to use the electricity they generate when the sun is shining. You need batteries to store the energy generated. These are expensive. – Solar cells convert the light from the sun into electricity.
