Solar energy production can be divided into 2 categories, namely;
Solar photovoltaic production uses energy from the sun to generate electricity. requiring daylight to work, not direct sunlight - a common misaprehension.
Photovoltaic cells are usually sited on south facing roofs or walls and contain layers of semi-conductive material. When in day light the semi-conductive material creates an electric current which is then used by the property or alternatively sold to the National Grid.
Solar thermal hot water systems have been utilised for many years in warmer climates uses the suns energy to heat water. The system can be used along side your existing water heating system and can also have a larger application for example heating swimming pools.
In a domestic situation solar hot water systems can provide approximately a third of the hot water needs while saving money and reducing CO2 emissions.
The system has three main components:
