How Colwyn Bay compares
Among the places we publish figures for, Colwyn Bay is one of 8 Denbighshire towns we track, and it ranks 7th of 8 for solar yield. It is a medium town in the House of Commons Library classification, with 29,030 residents, and its roofs see 2.56 peak sun hours a day across the year. That drives the standard 12 panel model to 5,934 kWh of generation, of which around 4,997 kWh is exported at 12p for £600 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
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 Colwyn Bay's own yield.
Any planning application in Colwyn Bay sits with Conwy, and its official House of Commons Library settlement class is 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.

The network operator for Colwyn Bay
The distribution network operator (DNO) for Colwyn Bay is SP Energy Networks, which runs the North Wales, Merseyside and Cheshire licence area.
For a typical home the paperwork is light: a system of up to 3.68kW per phase goes through G98, which means SP Energy Networks is notified within 28 days of switch-on rather than asked beforehand.
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 Colwyn Bay
A heat pump in Colwyn Bay
Heating demand peaks when solar is weakest. In Colwyn Bay, a 12-panel system makes about 140 kWh in December and 180 kWh in January, a fraction of its 790 kWh in May, which is why a heat pump here is costed on its tariff first.
In Wales, the Boiler Upgrade Scheme pays £7,500 towards an air source or ground source heat pump and £2,500 towards an air-to-air one, with £1,500 more until March 2027 for homes heated by oil or LPG with no mains gas (gov.uk, checked 28 September 2026).
Charging an EV in Colwyn Bay
Summer is where a car earns its place. In May, 12 panels in Colwyn Bay make about 790 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.
If you rent, or own a flat, and have private off-street parking, the government chargepoint grant covers 75% of the cost, capped at £500 a socket, until 31 March 2027 (gov.uk, checked 28 September 2026). The calculator above prices a 7.4kW smart charger from £1,100 installed.

Solar in Colwyn Bay: your questions answered
How much electricity do solar panels make in Colwyn Bay?
About 5,930 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Colwyn Bay: 933 kWh per kWp, or 2.56 peak sun hours a day on average. May is the strongest month, at about 790 kWh.
What does a typical solar system cost in Colwyn Bay?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Colwyn Bay, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 5,930 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Colwyn Bay, and what does it need from me?
SP Energy Networks covers Colwyn Bay. A home system of up to 3.68kW per phase is notified to SP Energy Networks within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. 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.
What happens to the solar I do not use in Colwyn Bay?
Around £600 a year at 12p per kWh, for the roughly 4,997 kWh a 12-panel system in Colwyn Bay exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Colwyn Bay get in December?
December is the low point: about 140 kWh from a 12-panel system in Colwyn Bay, on PVGIS data, rising to 790 kWh in May. From November to February the same system makes about 840 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Colwyn Bay 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 Colwyn Bay |
|---|---|---|
| Colwyn Bay | 933 | this town |
| Conwy | 933 | level |
| Llandudno | 966 | +33 kWh |
| Abergele | 950 | +17 kWh |
| Kinmel Bay | 1,002 | +69 kWh |
| Rhyl | 985 | +52 kWh |
| Prestatyn | 943 | +10 kWh |
Same PVGIS v5.2 query for every town. Small differences are within year-to-year weather; more than about 30 kWh per kWp apart is geography.
