Solar Photovoltaic

Solar Photovoltaic systems use free light from the sun to generate Electricity. There are a number of PV panel technologies, including polycrystalline, monocrystalline and thin-film. solar PV cells (for conservatories or glass) panels can be mounted on the roof or wall of a building or even floor mounted in a garden, with the latest PV technology, cells can also be integrated into the roof tiles themselves.

Solar Photovoltaic panels were developed over 50 years ago; again they are not a new technology however thanks to recent advancements with the panels and inverters they are now an economical and environmentally friendly solution in providing electrical energy.

The panels are made using several layers of semiconducting material, usually silicon based. The presence of Sunlight then creates an electrical field across the layers, the stronger the sun light the more electricity is produced. The electricity is then used to help run your lighting, heating and appliances, surplus electrical energy is also fed back to your supplier’s network for which you receive payment.

Groups of solar PV cells can be added together to provide increasing levels of power. This can range from small, 1-4 kilowatt-sized solar panels for use in domestic households, to larger arrays, which function as separate solar power plants feeding power directly into the electricity grid. PV panels and a micro-wind turbine utilises the fact that there is more wind in the winter when the sun is weak and vice versa to provide a more reliable energy supply. You may have seen this technology on temporary signage on the motorway; a typical combined solar and wind application. There are currently thousands of very small scale PV powered systems in use in the UK, for applications such as phone booths, street lighting, and signage.

PV cells do not need direct sunlight to work they can even generate some electricity on a cloudy day. The strength of a PV cell is measured in kilowatt peak (KWp) that is the amount of electrical energy the cell generates in full sunlight.

Domestic Systems range between 1 & 4 KW.

Planning is not normally required (see our planning guidelines).

Requirements approximately 15m2 of unshaded roof space which faces east to west through south, (south facing for best results), the roof must be strong enough to support the additional weight of the PV panels.

Benefits & Savings sunlight is free and the system will work all year round, although during winter months and very cloudy days electrical production will be considerably lower, you will save aproximately 40% of your elrectricity bill and reduce your CO2 emissions by about 1 tonne per year, whilst protecting yourself from future energy supplier increases, If you do not use all of the electricity you produce you can sell it back to your supplier.

You will also recieve generation and export payments through the FITs scheme between 21p per KW hour of electrical production plus 3.13p per KW exported. 

Maintenance Periodic performance tests, and visual checks of the panels and make sure they do not become very dirty or overshadowed by tree growth etc.

The above is based on a typical installation of 2.2 KW.
