How it Works

BatteryTailor analyses your property, postcode, roof, and energy usage using official PVGIS satellite data to model thousands of solar and battery combinations. In around 5 minutes you'll have four optimised scenarios , each with 20-year financial projections, payback analysis, and a full PDF report. No installer visit needed, no sales pressure, just independent data so you can walk into any installer conversation knowing exactly what to ask for.
