All solar savings calculations provided by this tool are estimates only. Results are based on average UK solar irradiance levels and assume a south-facing installation with optimal conditions. Actual performance may vary depending on panel placement, shading, roof angle, weather, and individual usage patterns. This tool is intended as a guide and does not constitute financial advice.
