You could save and earn £628 a year[1]

With Solar Photovoltaic (PV) panels you can generate your own electricity, meaning you could save and earn £628 a year[1]. Solar PV panels store energy from the sun and turn it into electricity. They’re easy to install and they don’t even need direct sunlight, just daylight. By generating your own electricity you could save on your energy bills. Plus with the Government’s Feed-in Tariff, you could be paid for every kilowatt hour (kWh) you generate. You can earn extra income for any electricity that you don’t use which can be fed into the grid.

The cost of installation and savings you could expect

Average annual earnings from the Feed-in Tariff[1]
 £397.58
Average annual earnings from the grid[1]
 £57.94
Average annual savings on your electricity bill[1]
 £172.53
Total annual earnings and savings[1] £628.05

We’ve based this example on how much you could earn by producing your own electricity using a 3 kWp solar PV system on a house with an EPC of level D. A system this size costs around £6,299 although the actual costs vary as renewable energy systems are tailored to your
specific needs.

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 electricity.* The average customer will generate 2,575 kWh of electricity per year so if you generated 50% of your own electricity each year you'd save:

£172.53 (1287.5 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 20 years. Current Government rates pay 16p for every kWh you generate and use. The average customer could generate 2,575 kWh of electricity per year, meaning a total income from electricity generated of:

£397.58 (2,575 kWh x 15.44p).

Average annual earnings from the National Grid

You'll also get an extra 4.5p 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 2,575 kWh you generate, you can sell 50% (1287.5 kWh) to the National Grid for an additional income of:

£57.94 (1184.5 kWh x 4.5p)

Total annual earnings and savings:

£628.05 (£172.53 + £397.58 + £57.94)

20 year earnings and savings:

20 x £628.05 = £12561.00

* 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.

How solar PV works

A solar PV panel consists of cells in one or two layers made from a semi-conducting material like silicon. When light shines on the cell it creates an electric field across the layers, causing electricity to flow. The electricity flows through a cable and is collected at a central point usually located in your roof space. The electricity is then converted from a direct current (DC) to an alternating current (AC) and carries on into your home for you to use.

Is your home suitable?

We offer a wide range of different sized solar PV panels, our Energy Experts will advise you on the best ones for your home. Panels are ideally placed on an unshaded, south-facing roof. But as they don't rely on direct sunlight, they work even on cloudy days.
