Our GB average is 925 kWh per kWp a year, the mean of the 85 county PVGIS estimates we publish; at 929, Denbigh is level with it.
How Denbigh compares
Small towns rarely get published solar figures, so here are the numbers for Denbigh. It is one of 8 Denbighshire towns we track, and it ranks 8th of 8 for solar yield, a town of 8,486 people in the House of Commons Library settlement data. PVGIS gives its roofs 929 kWh per kWp a year, 2.54 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £844 of year one benefit, £247 of it from your own generation and £597 from export at 12p.
Every figure here assumes a clear, south-facing roof at 35 degrees. Yours will differ, which is what the free design call is for; until then, the calculator below tests panels, batteries and export rates on Denbigh's own yield.
Any planning application in Denbigh sits with Denbighshire, 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.

The network operator for Denbigh
Denbigh is served by SP Energy Networks: the town's centre falls inside its North Wales, Merseyside and Cheshire licence area on NESO's boundary map.
Most home systems stay within 3.68kW per phase of inverter output, which puts them on G98, a notification to SP Energy Networks within 28 days of switch-on. Panel count does not decide it; the inverter and any battery do.
Larger systems go through G99 instead, applied for before installation. On timing: Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds SP Energy Networks as it does every network operator.

Beyond the panels: heating and car charging in Denbigh
A heat pump in Denbigh
In December, the darkest month here, 12 panels in Denbigh make about 180 kWh. That is when a heat pump runs hardest, so its running cost in Denbigh comes down to the tariff and the flow temperature rather than the roof.
The Boiler Upgrade Scheme, open in England and Wales, takes £7,500 off an air source or ground source heat pump, or £2,500 off an air-to-air unit. Homes on oil or LPG with no mains gas get £1,500 more until March 2027 (gov.uk, checked 28 September 2026).
Charging an EV in Denbigh
Summer is where a car earns its place. In May, 12 panels in Denbigh make about 760 kWh, against roughly 70 kWh a typical home uses in daylight that month on our calculator's typical-use settings, so there is surplus a smart charger can put into the car instead of exporting it.
Renters and flat owners with private off-street parking can get 75% off a chargepoint and its installation, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above adds a 7.4kW smart charger from £1,100 installed.

Solar panel servicing and repair in Denbigh
If a system in Denbigh is underperforming, start with the guides below: repair benchmarks, service scope, and the inverter question.
Solar in Denbigh: your questions answered
How much energy would 12 solar panels make in Denbigh?
Denbigh averages 2.54 peak sun hours a day, which PVGIS turns into 929 kWh per kWp a year. On a 12-panel, 6.36 kWp roof that is about 5,910 kWh, 69% of it between April and September.
What does a typical solar system cost in Denbigh?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Denbigh, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 5,910 kWh a year. The final figure comes from your roof on the design call.
Who is the network operator in Denbigh, and do I need a G99 application?
The operator is SP Energy Networks. Most home systems use the G98 route, a notification within 28 days of switch-on for up to 3.68kW per phase, so nothing waits on the network. Above that, G99 applies and has to be granted first. Ofgem's guaranteed standard for a low voltage generation connection quotation is 45 working days, with £80 paid for each working day late, and it binds SP Energy Networks as it does every network operator. Your design call checks which route yours needs.
What happens to the solar I do not use in Denbigh?
Around £597 a year at 12p per kWh, for the roughly 4,972 kWh a 12-panel system in Denbigh exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How does solar perform in Denbigh in the winter months?
December is the weakest month in Denbigh: about 180 kWh from 12 panels, against 760 kWh in May. The panels still generate on bright winter days; they just cover a smaller share of what the house uses.
How Denbigh compares with its neighbours
Same satellite dataset, same assumptions, so the differences are real geography rather than modelling noise.
| Town | kWh per kWp a year | vs Denbigh |
|---|---|---|
| Denbigh | 929 | this town |
| Kinmel Bay | 1,002 | +73 kWh |
| Rhyl | 985 | +56 kWh |
| Holywell | 952 | +23 kWh |
| Abergele | 950 | +21 kWh |
| Prestatyn | 943 | +14 kWh |
| Mold | 944 | +15 kWh |
Each row is a PVGIS v5.2 run at that town's centre with the same settings. Treat gaps of a few kWh as noise and gaps over about 30 kWh per kWp as real differences in sunshine.
