How Penarth compares
Among the places we publish figures for, Penarth is one of 32 Glamorgan towns we track, and it ranks 8th of 32 for solar yield. It is a medium town in the House of Commons Library classification, with 28,634 residents, and its roofs see 2.89 peak sun hours a day across the year. That drives the standard 12 panel model to 6,710 kWh of generation, of which around 5,773 kWh is exported at 12p for £693 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to Penarth's own yield, and at Penarth's 1,055 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.
Penarth sits within Vale of Glamorgan, its local planning authority, and the House of Commons Library classes it as a medium 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.

A 12 panel, 6.36 kWp system in Penarth generates around 6,710 kWh a year, worth around £939 in year one on the 12p export scenario.
Generation is modelled from PVGIS satellite data for Penarth's own coordinates (51.438, -3.18443), using the same 26.32p/kWh import value and £1,000 per kWp installed pricing as every Clearline estimate, with the full methodology, sourcing and assumptions set out on our help page.
