Savings Calculator
A conservative estimate in 30 seconds. No contact details needed to see your numbers.
Estimates use UK average generation of 950 kWh per kWp, 85% on-site use of what you generate, export income at 7p per kWh, and typical 2026 commercial installation costs. Deliberately conservative: excludes the Annual Investment Allowance and energy price inflation, both of which usually improve the real numbers.
