Let nature pay your bills and get an annual cash back under the Feed In Tariff.
Photovoltaic is a method of generating electricity from roof mounted silicon panels. Each unit of electricity generated qualifies for a clean energy cash back payment under the Feed In Tariff as well as saving money on buying electricity.
Photovoltaic panels absorb daylight and create an electrical field across the layers in the panel. The DC electricity is converter into AC electricity by an inverter before being connected to the distribution board for use in the property. Depending on the size of the installation, solar PV can typically generate around 50% of a property’s electrical needs.
Solar photovoltaic uses solar energy which is renewable and free. Most domestic PV systems will save around 1 tonne of CO2 per annum and there are no CO2 emissions from the PV electricity generation.
A set of polycrystalline panels can be mounted on an existing roof. For new build properties the panels can be incorporated within the roof tiles. Any unshaded roof orientation from west to east can work. A more southerly aspect is preferred. The brighter the day the more electricity is produced.
The sizing of a PV system is influenced by a number of factors such as available roof space, electrical consumption, capital budget and CO2 reduction targets.
Roof mounted PV is normally a permitted development in England and Scotland for residential properties, but check with your local planning authority. Planning permission is required in Wales, on listed buildings, non residential buildings and in conservation areas. Free standing or ground mounted PV systems also normally require planning approval.
Most systems are grid connected allowing surplus electricity to be sold. This attracts a further cash back under the Feed In Tariff. For sites not connected to the electricity grid a larger installation is needed with batteries to store the electricity generated.
The panels have a performance guarantee for up to 25 years and system components are warranted for up to 5 years. There are no moving parts and maintenance is usually restricted to keeping the panels clean and unobstructed.
Geowarmth supply and install systems from leading international manufacturers like BP Solar, Mitsubishi and Schuco. All systems are MCS accredited allowing the owner to benefit from the
Feed in Tariffs.
