Income & Returns

Typically in our region a well sited 4kwp Solar PV system will generate in excess of 3,750kwh/year of electricity. Exact output depends on the quality of the PV panels chosen, location, shading, pitch and orientation to south.

Annual earnings on such a system would be approx:

  • £152.63 in tax-free FIT income (Property with an EPC of D or above)
  • £337.50 in savings on your bill through use of your own free electricity
  • £94.31 in export income from power sold to the grid
  • £584.44 in total savings per year
  • £4999.00 inc VAT, fully fitted from price for a typical system

Income

The ‘Feed in Tariff’ means that all power suppliers are obliged to pay Solar PV owners a set rate per unit (kwh) of production for 20 years for ALL their Solar PV power. Even better, having been paid for ALL the home produced power you can then use your free electricity on-site and automatically export any excess to the grid, so you will always be earning in daylight hours. This income is tax-free for domestic PV. FIT rates vary according to the size of the array.

Below are the rates paid for each kilowatt-hour of electricity produced on properties with an EPC of level D or above:

PV Size FIT (pence)
≤4kwp 4.07p
4-10kwp 4.07p
10-50kwp 4.29p
50-250kwp 1.94p
Export rate 5.03p

These FITs will be paid for 20 years from the commissioning date of the system and are locked-in to the initial rate (indexed linked to the RPI to protect them from inflation) for the entire period. Furthermore the payments are tax-free for domestic properties. The initial rates may be reduced for new entrants to the scheme therefore it is advantageous to adopt Solar PV sooner rather than later. Feed in Tariff procedures and payment are under regular review, so please visit: www.energysavingtrust.org.uk/Generating-energy/Getting-money-back/Feed-In-Tariffs-scheme-FITs

Returns

A customer adding a PV System to a house would also benefit from the saving made on their existing bills by generating their own electricity rather than buying in that power. So the total benefit of the PV electricity used is actually 15p (grid price) + 4.07p (FIT income) = 19.07p per unit. It is estimated that in a typical home 60% of PV generated electricity is used on-site with a guaranteed 50% being automatically ‘deemed’ as exported to the grid earning an additional 5.03p per unit.

Other Benefits

Not all the financial benefits are realised on electricity production or use. PV systems add value to a property as they contribute to a higher EPC (Energy Performance Certificate) rating, as buyers will reap the rewards of the income generated and the reduced energy overheads. Furthermore, there are significant environmental benefits from producing your own clean energy and if requested we can detail the impact of this in terms of CO2 savings when we offer you a quotation.

What our Customers say…
Featured Articles
'The survey was to a much higher level of service than we had seen from others. The survey was very thorough rather than the "the fitters would sort that out on the day" that we had from others. Communications were prompt and they carried out our installation quickly to make sure we beat a drop in the feed in tariff'

‘If you are looking for the installation of solar panels, then Redmile Energy are the people to approach! After a thorough survey of our home, they gave us three quotes then arranged a date for installation within three weeks, all of this at less than half the price of the “big boys” for exactly the same panels!'

'No pushy salesmen here, just people who appeared honest and straightforward. I had quotes or visits from other companies, but found their sales people far too intimidating. All work completely neatly and tidily on time and to agreed budget.  Could not ask for more.'
