How Rhondda compares
Small towns rarely get published solar figures, so here are the numbers for Rhondda. It is one of 32 Glamorgan towns we track, and it ranks 32nd of 32 for solar yield, a town of 13,398 people in the House of Commons Library settlement data. PVGIS gives its roofs 882 kWh per kWp a year, 2.42 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £808 of year one benefit, £247 of it from your own generation and £561 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to Rhondda's own yield, and at Rhondda's 882 kWh per kWp it prices a 12 panel system at £6,360 installed before any battery. Your free design call reworks every number for your actual roof, its shading and your usage.

The charger is in the installed price but left out of payback: charging savings depend on your mileage and tariff, which the design call models properly.
