How Gwersyllt compares
Small towns rarely get published solar figures, so here are the numbers for Gwersyllt. It is one of 8 Denbighshire towns we track, and it ranks 4th of 8 for solar yield, a town of 7,676 people in the House of Commons Library settlement data. PVGIS gives its roofs 956 kWh per kWp a year, 2.62 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £864 of year one benefit, £247 of it from your own generation and £617 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 Gwersyllt's own yield.
Any planning application in Gwersyllt sits with Wrexham, 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.

Generation is modelled from PVGIS satellite data for Gwersyllt's own coordinates (53.07159, -3.01943), using the same 26.32p/kWh import value and £1,000 per kWp installed pricing as every Clearline estimate; the methodology is on our help page.
SP Energy Networks and your Gwersyllt connection
Gwersyllt 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 Gwersyllt
A heat pump in Gwersyllt
Heating demand peaks when solar is weakest. In Gwersyllt, a 12-panel system makes about 200 kWh in December and 220 kWh in January, a fraction of its 770 kWh in May, which is why a heat pump here is costed on its tariff first.
Grant support in Wales comes from the Boiler Upgrade Scheme: £7,500 for an air source or ground source heat pump, £2,500 for air-to-air, and an extra £1,500 until March 2027 where the home is heated by oil or LPG off the gas grid (gov.uk, checked 28 September 2026).
Charging an EV in Gwersyllt
Summer is where a car earns its place. In May, 12 panels in Gwersyllt make about 770 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.
The calculator above includes a 7.4kW smart charger from £1,100 installed. Renters and flat owners with off-street parking can claim 75% of a chargepoint's cost, up to £500 per socket, until 31 March 2027 (gov.uk, checked 28 September 2026).

Common questions about solar in Gwersyllt
How much electricity do solar panels make in Gwersyllt?
About 6,080 kWh a year from 12 panels (6.36 kWp), on PVGIS satellite data for Gwersyllt: 956 kWh per kWp, or 2.62 peak sun hours a day on average. May is the strongest month, at about 770 kWh.
What does a typical solar system cost in Gwersyllt?
Solar is priced at £1,000 per kWp installed wherever you live, so a 12-panel, 6.36 kWp system costs £6,360 in Gwersyllt, exactly as it would anywhere else, before any battery. Location changes what the system makes, not what it costs: here that is about 6,080 kWh a year. The final figure comes from your roof on the design call.
Which DNO covers Gwersyllt, and what does it need from me?
SP Energy Networks covers Gwersyllt. 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 Gwersyllt?
Around £617 a year at 12p per kWh, for the roughly 5,143 kWh a 12-panel system in Gwersyllt 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 Gwersyllt get in December?
December is the low point: about 200 kWh from a 12-panel system in Gwersyllt, on PVGIS data, rising to 770 kWh in May. From November to February the same system makes about 1,000 kWh in total, which is why a battery charged off-peak does more of the work in winter.
How Gwersyllt 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 Gwersyllt |
|---|---|---|
| Gwersyllt | 956 | this town |
| Brynteg | 955 | −1 kWh |
| Wrexham | 959 | +3 kWh |
| Rhosllannerchrugog | 957 | +1 kWh |
| Buckley | 958 | +2 kWh |
| Mold | 944 | −12 kWh |
| Hawarden | 962 | +6 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.

How to size a solar and battery system, properly
Usage, storage, connection, array. Four decisions, and the order between them matters.

Three phase buys 22kW charging. Most cars cannot use it, and load balancing usually solves the real problem.
