Solar Calculator

Free solar sizing estimate

Plan your solar setup without the guesswork.

Answer a few practical questions about the roof, scaffold, panels, inverter, battery storage and energy use. The calculator uses your current selling prices and sends us the property details needed for a Google Earth roof check.

This is a first-pass product, labour and scaffold estimate. Final install, cable runs and survey details are confirmed after the property check.

1. Roof details

Approximate dimensions are fine. If you know the rafter length for a pitched roof, add that as the roof length.

Roof type

2. Panels and hybrid inverter

Panels are priced at £120 each. The 480W Longi or similar option is selected by default.

3. Mounting, scaffold and add-ons

Solar panel fitting labour is £150 per panel including rails and hooks. Scaffold is calculated at £30 per m2 using either the direct area or length x height.

4. Energy use

Use either daily kWh or monthly bill. If you fill in both, the calculator blends them into a sensible estimate.

5. Property and contact details

These details help us find the property, check the roof online and get back to you with a more accurate recommendation.

The numbers are a guide. We will review the roof and follow up with a practical recommendation.

No payment is taken from this calculator. Prices shown are guide selling prices and can be refined after survey.
