Why should I install Solar PV?

  • Generate your own free electricity and save on your energy bills 
  • Optimise your self-consumption with an optional home battery 
  • Reduce your home's carbon emissions 
  • Receive income from Feed-in Tariff


How does it work?

Solar PV systems use the sun's energy to generate electricity. They're easy to install, low maintenance and can cut your energy bills from day one.

To maximise the use of your free solar energy you can now add a Tesla Powerwall home battery. With a home battery you can store the excess solar energy produced during the day and use it in the evening.


Why add a battery?

Tesla Powerwall’s pioneering car battery technology lets you store surplus electricity generated by solar panels during the day for use at home in the evening, and it comes with a 10 year warranty.

Is my home suitable?

Yes, if ...

  • You own your home, or you have the landlord’s permission
  • Your home has a south-facing, or at least south-east to south-west-facing roof
  • Your roof has enough unshaded space to install solar panels ( min 9.6m²)

Government Incentives supporting Solar PV

The government supports solar panel installation through the Feed-in Tariff (FIT), which pays owners of solar panels for every unit of electricity they generate and in addition pays for the exported electricity you don’t use (assumed at 50% and monitored via the export meter).

To get Feed-in Tariff (FIT) payments at the higher rate for your solar PV system, your property needs to have an Energy Performance Certificate (EPC) of band D or above.

If you have an EPC at band E, F or G you’ll need to carry out energy efficiency improvements before you apply for the FIT or receive a lower rate for the lifetime of the tariff, currently 20 years.

You’ll need to provide your EPC reference number to your FIT supplier showing your property is band D or above at the time of your application to receive the higher rate (for a system under 4kW) rather than the lower rate.

If your property is a band E or less when you first apply for the FIT you’ll receive the lower rate. If you improve your property’s EPC band to a D or higher at a later date you’ll still get the lower rate. This is not a retrospective requirement for existing solar PV systems.
