Question

How is solar energy is used to produce electricity

Answer 1

Answer:

Explanation:

Solar-powered photovoltaic (PV) panels convert the sun's rays into electricity by exciting electrons in silicon cells using the photons of light from the sun. This electricity can then be used to supply renewable energy to your home or business.

Answer 2

Solar energy systems either use photovoltaic (PV) panels or mirrors to focus solar radiation to convert sunlight into electrical energy. This power can be converted into electricity, or it can be stored thermally or in batteries.

Solar Energy:

Any energy produced by the sun is referred to as solar energy. For human use, solar energy can be directly or indirectly captured.

Generating Electricity

• Solar cells can directly convert solar radiation into electricity (photovoltaic cells).
• When light contacts the junction between a metal and a semiconductor (such as silicon) or the junction between two separate semiconductors in such cells, a small electric potential is produced.
• Observe the photovoltaic effect.
• A single solar cell normally only produces two watts of power.
• However, hundreds or even thousands of kilowatts of electric power can be produced in a solar electric plant or in a big domestic array by joining numerous individual cells together, as in solar-panel arrays.
• Since the intensity of solar radiation is already low, most modern photovoltaic cells only have an energy efficiency of 15 to 20 percent, and in order to generate even modest amounts of power, large and expensive assemblies of these cells are needed.
