What could your
home save?
Two minutes for an estimate, thirty seconds for a call back. Either way, no obligation and no pushy sales calls.
Estimate your saving.
Please enter your address and choose a roof direction.
Assumes electricity bought at 28p and exported at 15p per kWh, 950kWh a year from each kWp on a south-facing roof (less for other directions), and up to 85% of generation used at home with a battery, never more than the home uses, with the rest exported. Cheap-rate battery charging, future price changes and install cost are not included.

Real proposals go much deeper.
The calculator uses a handful of stated assumptions. Your proposal is modelled properly: your roof from satellite imagery, your actual half-hourly usage where available, your tariff, and the right system for your home.
Your roof, not a template
Orientation, pitch and shading analysed panel by panel, so the generation figure you see is the one your roof can actually deliver.
Your tariff, factored in
Time-of-use and agile tariffs change the maths significantly. We model your battery against the tariff you're actually on, or the one you should be.
If it doesn't stack up, we say so
Not every home suits solar. If the numbers don't work for you, we'll tell you, and tell you why.
