Solar power is a clean and sustainable energy source that uses the Sun''s energy to generate electricity. Solar cells, also known as photovoltaic cells, convert light energy
There are two key ways of capturing and using this energyfrom the Sun: solar panels (photovoltaics), which convert light into electricity, and solar thermal power, which transforms
There are two key ways of capturing and using this energyfrom the Sun: solar panels (photovoltaics), which convert light into electricity, and solar thermal power, which transforms the Sun''s energy into heat.
Electricity can be generated in a number of different ways. Find out how in this guide for KS3 physics students aged 11-14 from BBC Bitesize.
So, how does solar energy work? The answer lies in the science of photovoltaics. Photovoltaics is a process that converts light energy into electrical energy. This process is achieved by using solar cells that are made up of semiconductors
Solar panels Solar panels do not generate electricity, but rather they heat up water. They are often located on the roofs of buildings where they can receive heat energy from the Sun.
Solar cells transfer light energy from the Sun into electrical energy directly. When sunlight hits layers of silicon inside solar cells, an electric charge builds up, creating a flow of...

Solar panels on the Isle of Eigg, Scotland. Find out how the sun can be used to generate electricity. Electricity is generated from energy from the Sun by solar panels. These are made up from individual solar cells (also called photovoltaic cells). Light from the sun passes through the glass cover of a solar cell.
There are two key ways of capturing and using this energyfrom the Sun: solar panels (photovoltaics), which convert light into electricity, and solar thermal power, which transforms the Sun’s energy into heat.
The water is heated by heat energy from the Sun and returns to the tank. In some systems, a conventional boiler may be used to increase the temperature of the water. Solar energy is a renewable energy resource and there are no fuel costs. No harmful polluting gases are produced. Solar cells do not work at night.
Making solar cells requires rare metals as well as lots of energy and water. Learn how energy from the sun is used to generate renewable electricity at solar power plants around the world. BBC Bitesize Scotland Learning for Sustainability guide for Third and Fourth Level CfE.
Unlike other energy sources, generating electricity from solar power does not use turbines. Solar cells transfer light energy from the Sun into electrical energy directly. When sunlight hits layers of silicon inside solar cells, an electric charge builds up, creating a flow of electricity.
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.
