Solar Panel Cost in Bristol (2026)
Model Bristol solar ROI with local electricity rates, installed costs, and incentives.
Last updated: 2026-06-25· Source label: EIA residential electricity rates, IRS federal clean energy credit, NREL/PVWatts solar assumptions
Bristol benefits from England's best solar production outside the South East, at 3.6 peak sun hours/day. A 3.5 kW system costs £5,565-£6,964 at 0% VAT. The combination of near-average install costs and above-average sun hours makes Bristol one of the best UK markets for solar, with payback in 7-9 years. The Ofgem price cap rate of 24.67 p/kWh and SEG export income provide steady savings.
