How these estimates are calculated
Output 473 kWh/yr (473 × 1)
Saving £86.45/yr (70% used at home)
Payback 3.9 yrs (£334.97 ÷ £86.45) Assumptions: PVGIS 5.3 estimate for a 460W crystalline-silicon panel, south-facing at 35 degrees near Harpenden, with 14% system loss. Actual output varies with location, orientation and shading. Simple payback uses self-consumed electricity only. It excludes export income, standing charges, maintenance, finance, degradation and future tariff changes.
Electricity rate: Ofgem GB average price-cap electricity unit rate, Direct Debit (26.11p/kWh; 2026-07-01–2026-09-30).
