How Wrexham compares
Among the places we publish figures for, Wrexham is one of 8 Denbighshire towns we track, and it ranks 2nd of 8 for solar yield. It is a medium town in the House of Commons Library classification, with 45,585 residents, and its roofs see 2.63 peak sun hours a day across the year. That drives the standard 12 panel model to 6,099 kWh of generation, of which around 5,163 kWh is exported at 12p for £620 a year, with £247 saved on electricity you would otherwise buy at 26.32p.
These are starting numbers, not a quote. The calculator below opens on Wrexham's own PVGIS figure; change the panels, the battery or the export rate and it reruns. The design call replaces every assumption with your roof and your bills.
Planning applications in Wrexham go to its own council, 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.

Connecting solar to the Wrexham network
SP Energy Networks owns and runs the local electricity network in Wrexham, as part of its North Wales, Merseyside and Cheshire licence area.
What decides the paperwork is the inverter and battery output, not the number of panels. Up to 3.68kW per phase, a system follows G98: SP Energy Networks is notified within 28 days of commissioning and nothing has to be approved first.
A bigger inverter or battery output needs a G99 application in advance. 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.

Adding a heat pump or an EV charger in Wrexham
A heat pump in Wrexham
Solar and a heat pump pull in opposite directions through the year: Wrexham's roofs make 1,000 kWh from November to February on a 12-panel system, and 2,920 kWh from May to August. The heating season leans on the grid, so off-peak rates do the heavy lifting.
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 Wrexham
From April to September, 69% of a Wrexham roof's yearly output arrives, peaking at about 770 kWh in May on 12 panels. A car parked at home in daylight can soak up what the house, at around 70 kWh of daytime use that month, cannot.
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 Wrexham
What could a roof in Wrexham generate?
PVGIS puts a roof in Wrexham at 959 kWh per kWp a year, 2.63 peak sun hours a day averaged across the seasons. A 12-panel, 6.36 kWp system makes about 6,100 kWh a year, most of it between April and September.
How much are solar panels in Wrexham?
The price does not move by postcode. At £1,000 per kWp installed, 12 panels (6.36 kWp) come to £6,360 in Wrexham before a battery. What Wrexham changes is the return, about 6,100 kWh a year from that system, and your design call prices your actual roof.
Do I need permission from the DNO for solar in Wrexham?
Usually not in advance. SP Energy Networks, the network operator for Wrexham, only needs a G98 notification within 28 days of commissioning for systems up to 3.68kW per phase. Bigger inverter or battery outputs need G99 approval 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. "See our DNO explainer.
How much can I earn from exporting solar in Wrexham?
With typical use and no battery, a 12-panel system in Wrexham exports about 5,163 kWh a year. At 12p per kWh that is roughly £620; a supplier paying more, or a battery that keeps more for the evening, changes the figure. See the export rates table.
Do solar panels work in winter in Wrexham?
Yes, at a lower level. PVGIS gives Wrexham 31.6 kWh per kWp in December and 33.4 in January, so a 12-panel system makes about 200 kWh and 210 kWh in those months, against 770 kWh in May. Winter output mostly covers daytime use rather than exporting.
How Wrexham compares with its neighbours
How the towns nearest Wrexham compare on the same PVGIS settings, closest first.
| Town | kWh per kWp a year | vs Wrexham |
|---|---|---|
| Wrexham | 959 | this town |
| Gwersyllt | 956 | −3 kWh |
| Brynteg | 955 | −4 kWh |
| Rhosllannerchrugog | 957 | −2 kWh |
| Buckley | 958 | −1 kWh |
| Hawarden | 962 | +3 kWh |
| Mold | 944 | −15 kWh |
PVGIS v5.2 for each town centroid, identical assumptions throughout. A few kWh either way is weather-year noise; a spread beyond about 30 kWh per kWp is real geography.
