How Dinas Powis compares
Small towns rarely get published solar figures, so here are the numbers for Dinas Powis. It is one of 32 Glamorgan towns we track, and it ranks joint 5th of 32 for solar yield, a town of 8,095 people in the House of Commons Library settlement data. PVGIS gives its roofs 1,058 kWh per kWp a year, 2.90 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £942 of year one benefit, £247 of it from your own generation and £695 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to Dinas Powis's own yield, and at Dinas Powis's 1,058 kWh per kWp it prices a 12 panel system at £6,360 installed before any battery.
