The current domestic rate on the FiT is £4.25 per unit generated, that applies to systems of 0-10kW in size. Recent reduction in panels cost can now be passed to the consumer and now offers an excellent investment opportunity. See the Feed in Tariff generation and export payment rate table from Ofgem here.
PV panels are capable of being installed on the vast majority of UK homes. Whilst there are some subtle differences in installation procedure dependent upon your roof type - see our PV case studies for examples - only homes with thatched roofs are truly problematic. Also be aware that one KW of solar PV takes up 8m2 of roof space more on flat roofs
Solar PV is appropriate for homes in most urban and rural locations in the UK. The amount of energy received from the sun does vary across the UK - but it not by a large amount. The most important thing to watch out for when considering installing a PV system is shade; beware of any trees, buildings and other obstructions, lying to the South.
