Find out how much you can earn by installing solar panels:

Assumptions

Installed cost

The solar panel system price includes:

• Sharp solar panels (UK).
• SMA Inverter (German).
• Schüco mounting system (German high quality anodised aluminium and stainless steel).
• VAT.
• Standard scaffolding (£350 + VAT).

This is the fully installed cost, using high quality components, with no hidden extras.

We consider requests for price matching on a like-for-like basis for systems using cheaper panels, inverters or mounting systems.

Generation income

• The annual amount you would expect to receive from your energy supplier.  It is paid regardless of whether the electricity is used or exported.
• This is know as the generation tariff.  The rate is 21p per kWh.

Export income

• The energy supply companies are required by the government to pay you, in addition to the generation tariff, 50% of the electricity that is generated.  The rate is 3.1p per kWh.

Savings on bills

• How much you are likely to save on your electricity bill.
• Cost of electricity is 13p per kWh.
• 50% of the electricity generated by the solar panels is used in your home.

General assumptions

• Excludes any increase in electricity prices, which would make the savings even greater.
• The panels will not suffer from losses in output over time (losses are likely to be more than offset by electricity price increases).
• Excludes inflation.
• Excludes maintenance (cleaning of panels, replacement of inverter, insurance costs).  The inverter may need changing every 8 to 10 years.  The inverter costs approximately 10% of the system cost to replace.  Sharp solar panels are self cleaning.  Your household insurance premium may increase as a result of installing solar panels.
• None or very little shading (< 20%).
• Tilt of panels is 30°.
