How Llandudno compares
Small towns rarely get published solar figures, so here are the numbers for Llandudno. It is one of 4 Caernarfonshire towns we track, and it ranks 1st of 4 for solar yield, a town of 14,746 people in the House of Commons Library settlement data. PVGIS gives its roofs 966 kWh per kWp a year, 2.65 peak sun hours a day averaged across the seasons, and the standard 12 panel model turns that into £872 of year one benefit, £247 of it from your own generation and £625 from export at 12p.
Treat these as calibration rather than a quote. The calculator below runs the same model, opened on Llandudno's own yield, and 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.
Planning applications here go through Conwy; nationally, the House of Commons Library classes Llandudno 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.

Generation is modelled from PVGIS satellite data for Llandudno's own coordinates (53.31849, -3.82445), 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.
The network operator for Llandudno
On NESO's licence-area map, Llandudno is in North Wales, Merseyside and Cheshire, which SP Energy Networks operates. That makes SP Energy Networks the network operator for any system fitted here.
Below 3.68kW per phase of inverter and battery output, the G98 route applies: the installation is notified to SP Energy Networks within 28 days of commissioning, with no prior approval.
Above that, G99 means applying before the work is booked. 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.

Heat pumps and EV charging in Llandudno
A heat pump in Llandudno
Heating demand peaks when solar is weakest. In Llandudno, a 12-panel system makes about 170 kWh in December and 200 kWh in January, a fraction of its 820 kWh in May, which is why a heat pump here is costed on its tariff first.
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 Llandudno
Llandudno's May output, about 820 kWh from 12 panels, is several times the 70 kWh or so a typical home uses in daylight that month on our calculator's settings. Daytime charging turns that surplus into miles.
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.

Is solar more expensive in Llandudno?

Which DNO covers Llandudno, and what does it need from me?
SP Energy Networks covers Llandudno. 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 could I earn from exporting in Llandudno?
On the 12p export scenario, a 12-panel system in Llandudno sends about 5,207 kWh a year to the grid, worth around £625. The export rates table compares what each supplier pays.
How much solar does Llandudno get in December?
December is the low point: about 170 kWh from a 12-panel system in Llandudno, on PVGIS data, rising to 820 kWh in May. From November to February the same system makes about 930 kWh in total, which is why a battery charged off-peak does more of the work in winter.
