Solar electricity systems vary

It’s worth bearing in mind that although you’ll pay more for a system that can produce more electricity, you’ll end up saving more too.

You can have solar ‘tiles’ that look like roof tiles, or panels built into your roof rather than sitting on top, but these are a more expensive option.

Install prices start from around £4,000 (including VAT at only 5%).

An average 2.2 kWp (kilowatt-peak) system could give you:

  • around 40% of the electricity your home uses in a year;
  • annual savings and income of about £530;
  • an environmental saving of around 1 tonne of CO2 a year.

How the Feed-in Tariff scheme works

The Feed-in Tariff (FIT) scheme became available in Great Britain in April 2010. The tariff is guaranteed for 25 years and linked to the Retail Price Index (RPI), which means it follows the rate of inflation.

It guarantees you:

  • a set rate paid by your energy supplier for each unit (kWh) of electricity you produce (called the Generation Tariff);
  • an additional payment of 4.85p/kWh for the electricity you don’t use and which you send back to the grid (Export Tariff), or a payment based on an estimated export rate, usually 50%

Remember you’re also making significant savings on your current energy bills.

To qualify for the full FIT payments, your system must be fitted by a supplier recognised by the Microgeneration Certification Scheme (MCS). Parker Energy not only has the necessary certification, but also the electrical installation experience and expertise to supply the ideal system for your property.

Cost Illustration as follows: Based on an 2.2KWp (12 panel) installation carried out on a existing Property with a south facing roof with a roof angle of 35 degrees and exporting 25% of the Electricity generated

This would Generate 1910KWh per Annum*

Income from the feed in Tariff would be: £284.59
Income from Exported Electricity: £22.17
Electricity Bill Savings: £221.96
TOTAL £526.72

*It would also save 1 Tonne of CO2 emissions. Source

The tariffs should cover the initial capital cost and according to the Government, earn a return up to 8% per annum. In practice that means you should recover the capital cost at least twice over the duration of the tariff.
