What is solar power & how does it work?

Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Solar panels use the photovoltaic effect to convert light into an electric current.

How is solar energy generated?

Solar energy - Electricity Generation: Solar radiation may be converted directly into solar power (electricity) by solar cells, or photovoltaic cells. In such cells, a small electric voltage is generated when light strikes the junction between a metal and a semiconductor (such as silicon) or the junction between two different semiconductors.

How is solar energy converted to electricity?

Energy from sunlight or other renewable energy is converted to potential energy for storage in devices such as electric batteries or higher-elevation water reservoirs. The stored potential energy is later converted to electricity that is added to the power grid, even when the original energy source is not available.

How does a solar photovoltaic system generate 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. Let’s examine each of these systems in more detail. How does solar thermal generate electricity? How do photovoltaic solar panels generate electricity?

What is solar power?

The Editors of Encyclopaedia Britannica This article was most recently revised and updated by Melissa Petruzzello. Solar power is a form of energy conversion in which sunlight is used to generate electricity.

What is solar energy used for?

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 concentrating solar-thermal power technologies, electrical grid systems integration, and the non-hardware aspects (soft costs) of solar energy.
