This tool provides rough estimates based on typical UK household profiles. It does not account for individual usage patterns, grid export revenue, battery degradation state, or seasonal variation. Results are indicative only and should not be used as the basis for financial decisions.
Key assumptions: Peak electricity rate: 28p/kWh. Battery system cost: ~£5,000 with 4,000 cycle lifespan (~£0.08/kWh wear for a 10 kWh system).
Rates and costs vary by supplier, region, and equipment. Check your actual tariff before making decisions.
