How Holywell compares
Small towns rarely get published solar figures, so here are the numbers for Holywell. It is one of 8 Flintshire towns we track, and it ranks 6th of 8 for solar yield, a town of 7,806 people in the House of Commons Library settlement data. PVGIS gives its roofs 952 kWh per kWp a year, 2.61 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £861 of year one benefit, £247 of it from your own generation and £614 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, defaulted to Holywell's own yield, and at Holywell's 952 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.
Holywell sits within Flintshire, its local planning authority, and the House of Commons Library classes it as a 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.

A 12 panel, 6.36 kWp system in Holywell generates around 6,055 kWh a year, worth around £861 in year one on the 12p export scenario.
Generation is modelled from PVGIS satellite data for Holywell's own coordinates (53.27549, -3.22543), 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.

What does a typical solar system cost in Holywell?

Your design call checks which applies in Holywell before anything is booked; our G98 vs G99 guide explains the difference in full.
