* Illustrative solar PV performance figures only. They depend on PV position on your roof, location in UK, other factors. Year-on year variations can be around 10%. These figures would be typical for an average year in Sheffield. They would usually be higher by 10% or more in sunny southern areas such as Cornwall, and lower by 10% or more in Scotland.
** Exact PV subsidy figures cannot be predicted because they depend performance, as mentioned above. We are using a figure of 42.5p per kWh, which assumes that 50% of the electricity you generate will be exported to the grid for others to use.
*** Assuming PV energy delivery as before, that you pay 12p per unit and that half of the solar electricity that you generate will be used in your home. We are well aware that several other PV sites claim that all the electricity will be used in your home, but we would ask you to please question this assumption, since it is likely to be over-optimistic.
The prices assume:
- This is a one storey installation. For two storeys, add just £500 to cover extra roof access costs.
- You have one suitable sunny roof elevation and the roof does not need any structural changes.
- You live in a building where scaffolding is easy and there are no major obstructions such as bay windows.
- You live on the UK mainland with mains electricity already supplied and that you have a “grid-connected” installation.
We can quote for most homes. Just tell us your budget, or your unshaded roof areas and together we can quickly do the rest in terms of price and performance. Even if your home does not quite satisfy all these standard price conditions, or if you do not live in the UK, please call us anyway. We will usually be able to quote. We are also able to install PV (photovoltaics) in Northern Ireland and in most UK Islands. We can supply any size of domestic PV installation between 1-4 kW peak. Installations which are intermediate in size between the listed sizes are charged at £5 per extra Watt peak installed, the price being charged above the lower price break.
