By the numbers

North Wales solar, measured.

Typical yearly generation, per kW of panels

≈943 kWh per kWp a year — around the UK average

For every kilowatt of panels, a well-placed North Wales roof generates about this much a year. Your own total depends on roof direction, pitch and shading — the roof check estimates it for your address.

Local context

Solar in North Wales: quick guide.

North Wales is a whole region rather than a single city. This page covers the entire LL postcode area, from Wrexham and the Denbighshire towns, along the north coast, through Gwynedd and Snowdonia to Anglesey and the Llŷn peninsula:

  • Coastal towns. Rhyl, Colwyn Bay, Llandudno and the north-coast resorts have Victorian and terraced seafront stock. Fine for solar, though salt air and wind mean fixings are specified for the setting.
  • Eryri (Snowdonia) National Park. Homes inside the National Park and its many conservation villages carry stronger planning conditions on visible panels. A local installer will know the route.
  • Rural, off-gas homes. Much of Gwynedd and Anglesey is off the mains gas grid, where solar paired with battery storage can offset relatively expensive heating and power.
  • Welsh slate roofs. Traditional Welsh slate is common across the region and works well for solar, with the structural check mattering more on older roofs.
  • Welsh planning. Permitted-development rules in Wales differ from England, so it is worth confirming the local position early.

Grants & support

What help is available in North Wales?

Solar and battery installations across the UK are currently zero-rated for VAT until 31 March 2027 — a straight saving on the installed price for every household, with no application needed. In Wales, the Welsh Government's Nest scheme supports eligible households with home-energy improvements, alongside the GB-wide schemes.

Eligibility for grant schemes depends on your income, home and circumstances, and the schemes change. We keep the current picture on one page rather than guess what you'll qualify for.

Common questions

FAQs about solar in North Wales.

Do I need planning permission for solar panels in North Wales?

Most domestic installations are permitted development under Welsh planning rules, which differ from England. Homes inside Eryri (Snowdonia) National Park, conservation areas and listed buildings carry extra conditions on visible panels. A local installer will know the relevant council or National Park position, and an installer survey confirms suitability first.

Is solar worth it in North Wales?

Yes. The region gets less peak sun than the south of England, but modern panels still generate usefully across the year, and for the many off-gas rural homes here solar with battery storage can offset expensive heating and power. Roof direction and shading matter most, and your Solarable Report estimates your roof’s likely main direction before you book a survey.

How much does a solar installation cost in North Wales?

Prices are broadly in line with the UK average, though remote and exposed sites can add access and fixing cost. A typical 4 kWp system lands in roughly the £4,800 to £6,800 range installed, with battery storage adding around £3,000 to £6,000. Solar and battery are zero-rated for VAT until 2027, and the on-roof survey gives the firm figure.

This is a region, not one city. Which areas does it cover?

North Wales is genuinely one region, so this page covers the whole LL postcode area. That runs from Wrexham and the Denbighshire towns, along the coast through Rhyl, Colwyn Bay and Llandudno, into Gwynedd and Snowdonia, and out to the Llŷn peninsula and Anglesey. Most listed installers cover a broad patch, so it is worth checking each firm’s stated coverage.
