WHY INSTALL SOLAR PV?
- Reduce carbon emissions
- Reduce or eliminate electricity bills
- Increased security of electricity supply
- Protection against price rises
- Earn £815.26 tax free from the feed in tariff each year
- An investment that will pay for itself well within its lifetime.
Solar electricity (Photo Voltaic) – solar panels on your roof will convert sunlight into electricity which is used to generate electricity in your home. A home owner can claim through the FIT SCHEME 43.3p (up to March 2012) for every unit of electricity generated.
Solar Panels will generate electricity from sunrise to sunset, enabling customers to obtain maximum efficiency from their units. They work well in the winter, generating energy from the winter sun even when the days are quite short. They generate electricity by the light /sun being absorbed by the panels.
Installation is quick, clean and easy. A large roof can be completed in approximately 2-3 days. Most of the equipment will be sited in your loft space out of every day view.

What is the Feed-In Tariff?
The Feed-In Tariff Scheme, or FITS, has been designed to boost the take-up of self generation in homes and businesses by enabling the customer to claim generous rates through this scheme for a period of 25 years.
Homes and businesses claiming the Feed in tariff are entitled to:
- Use any electricity generated by their system for free.
- Claim 43.3p per Kwh of electricity generated, irrespective if you use it or not
- Sell back any electricity you don’t use for an extra 3.1p per Kwh.
FITS are unlikely to form any part of the government cuts as they are not obtained through government funding.
Who pays for the Feed-In Tariff?
Many people think that the Feed-In Tariff payments come direct from the government. This is not correct. It actually comes from the energy companies who, in turn, pass this cost on to the consumer in the form of higher energy prices. This means that people without solar PV are subsidising those people with solar PV.
How to calculate your Feed-In Tariff return
SAP 2009 - The Government's Standard Assessment ProFeed in Tariff = £815.26 per annum based upon SAP 2009 formula calculation. Excludes; uplift for indexation, any increase in energy costs from provider, payments from energy sold back to provider, rebates for own energy used. To predict the performance of a Solar PV System using the Government's Standard Assessment Procedure (SAP) the following is to be applied: 0.8 x kWp x S (annual solar radiation from table H2) x ZPV (Overshading Factor from table H4)= 1974 x Feed in Tariff currently £0.413 = £815.26 This amount assumes system kWp is 2.3, 30 degree tilt, not overshadowed and south facing orientation.cedure for Energy Rating of Dwellings
