These systems, which are often seen as solar panels or solar roof tiles, use energy from sunlight to generate electricity which can be used to run appliances and lighting.
The greater the intensity of light, the greater the generation of electricity.
Panels are not light and installation will be subject to the strength of your roof. These systems are best suited for a building with a south, south east or south west facing wall or roof and with minimal shading. Systems must be MCS (Microgeneration Certificate Scheme) approved and be fitted by experienced MCS accredited installers.
Cost and maintenance
A typical domestic system is around 2.2 kilowatt-peak units in size and would produce over 40 percent of the electricity needed for a domestic home. A 2.2 kilowatt-peak unit system would cost around £6,000. Solar tiles are more expensive than conventional panels. Once installed there are no running costs, but the inverter may need replacing after eight to 10 years.
This system is eligible for the Feed In Tariff.
