Solar power produces electricity by making use of a process known as the photovoltaic effect. Solar panels convert the sun’s rays in to electricity using this effect which can be used to recharge batteries and provide electricity for homes. Another version of solar panels use the sun’s energy to heat water for the home.
There are other ways to make use of the sun’s energy. Building design can used to collect the sun’s heat. This is done building the structure so it faces the sun, using large glass windows help absorb the sun’s rays and heat the building. Used mainly in the UK is using the sun to heat water using the sun’s rays.
Homes with solar panels are able to generate more electricity than they require and can sell this back to the national grid.
It is however quite expensive to produce solar panel. The costs are getting lower year after year and you can even get subsidies from the government when using solar panels on your home.
