Solar electricity systems, also known as photovoltaic (PV) solar electric systems, harness the sun’s energy in order to produce electricity for running household appliances, domestic heating and lighting.

PV systems consist of flat panels that you attach to your roof. Each panel consists of small PV cells which convert sunlight into electricity using thin layers of silicon to trap the sun’s rays. Although the stronger the sunshine, the more electricity that can be produced, PV systems do not need bright sunlight to function – they can generate electricity even on cloudy days. 

The strength of a PV cell is measured in kilowatt peak (kWp) which refers to the amount of energy the cell generates in full sunshine. PV solar electric systems are the only solar electricity generating systems that qualify for the Government’s Feed-in Tariff scheme.

Local Planning. There is now a presumtion in favour of allowing planning consent for Solar PV systems, except in certain sensitive or conservation areas. The Building Control Approval has now been delegated to NAPIT (National Association of Professional Inspectors and Testers), of which Princes Electrical is a member. For more information click here.
