How Porth compares
Small towns rarely get published solar figures, so here are the numbers for Porth. It is one of 32 Glamorgan towns we track, and it ranks 24th of 32 for solar yield, a town of 13,467 people in the House of Commons Library settlement data. PVGIS gives its roofs 961 kWh per kWp a year, 2.63 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £868 of year one benefit, £247 of it from your own generation and £621 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to Porth's own yield, and at Porth's 961 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.
Any planning application in Porth sits with Rhondda Cynon Taf, and its official House of Commons Library settlement class is small town.
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.

What does a typical solar system cost in Porth?
