Estimates use the Ofgem Q3 2026 average electricity rate of 26.11p/kWh and a 12p/kWh Smart Export Guarantee rate. Actual generation and savings depend on your roof, shading, tariff and usage. Figures are illustrative, not a quote.

How solar panels cut your electricity costs
Why solar makes a difference to your bills
Every other bill on this site is set by someone else. Solar is the exception: once the system is paid off, the electricity it generates is free.
The Energy Saving Trust reports that an average domestic system of around 4.5 kWp — roughly 12 panels costing about £6,100 — can save a typical home in the region of £750 a year — and up to around £1100 for a larger system — while cutting around 1 tonne of CO₂. (Energy Saving Trust ↗)
Your saving comes from two places: the electricity you use directly instead of buying from the grid at the Ofgem cap rate, and the surplus you sell back through Ofgem's Smart Export Guarantee at around 12p per unit. (Ofgem SEG ↗)
