Solar PV

The following figures are calculated using our 2.76 kWp solar PV system.

Average annual saving on your electricity bill

Generating your own electricity means you don't have to buy it from your supplier - you'd normally pay us 13.4p per kWh if we supplied your electricity¹. The average customer will generate 2,369 kWh of electricity per year so if you generated 50% of your own electricity each year you'd save:

£158.72 (1184.5 kWh x 13.4p)

Average annual earnings from the Feed-in Tariff

With the Government's Feed-in Tariff you could be paid for the electricity you generate for at least the next 25 years. Current Government rates pay 21p for every kWh you generate and use. The average customer could generate 2,369  kWh of electricity per year, meaning a total income from electricity generated of:

£497.49  (2,369  kWh x 21p).

Average annual earnings from the National Grid

You'll also get an extra 3.1p for every kWh you generate but don't use which is fed into the National Grid. So for example, if you use 50% of the 2,369 kWh you generate, you can sell 50% (1184.5 kWh) to the National Grid for an additional income of:

£36.72 (1184.5 kWh x 3.1p)

Total annual earnings and savings:

£692.93 (£158.72 + £497.49 + £36.72)

25 year earnings and savings:

25 x £692.93 = £17,323.25

¹ Payments for Solar PV panels for the electricity you generate and use began in April 2010 as part of the Government’s Feed-in Tariffs. Rate from 1st April 2012 21 p/kWh used onsite and an additional 3.1 p/kWh used for export. Rate applies only to installations fitted to or wired to existing buildings prior to April 1st 2012. 50/50% split between electricity used onsite and excess exported back to the grid on a typical export tariff. Unit price used in calculation representative of the average p/kWh charge, as derived from the annual bills at industry average consumption of 16,500 kWh for gas and 3,300 kWh for single rate electricity, paying by Monthly Direct Debit on our Standard Tariff prices as at 11th January 2012, averaged across all regions and including VAT. 50% onsite consumption number sourced from the Feed-in Tariffs (Specified Maximum Capacity and Functions) Order 2010. The figures do not take into account any maintenance, repair or other costs required during the 25 year period. Correct as at February 2012 and subject to change.
