This calculator converts your solar panel output into everyday equivalents so you can understand what solar actually delivers.
Assumptions: 420W panels, UK average of 2.66 peak sun hours per day (950 kWh/kWp/year), 85% system efficiency. EV figures use manufacturer WLTP efficiency ratings.
Savings: Based on 50% self-consumption at 24.5p/kWh, with surplus exported at 5.5p/kWh via the Smart Export Guarantee (SEG).
Actual results vary by location, roof orientation, shading, and usage patterns. These are UK averages for illustration.
TradeCalc provides free estimation tools for UK construction professionals and homeowners. While we strive for accuracy, all results are approximate and should be verified by an MCS-certified installer.
TradeCalc accepts no liability for any decisions made based on these estimates.
