Solar panels in North Wales, in brief

MARA Electrical are MCS certified, NICEIC approved solar panel installers based at Queensferry on Deeside, covering the whole of North Wales. A well-sited roof in North Wales typically generates around 900 to 1,000kWh per year for every kWp installed, so a 4kWp home system produces roughly 3,600 to 4,000kWh a year. We survey, design, install and certify the system ourselves, handle the SP Energy Networks notification, and issue the MCS certificate you need for Smart Export Guarantee payments.

Why North Wales Chooses MARA

A Local Installer That Also Does the Big Jobs

Most installers in North Wales are either a two-van domestic outfit or a national sales operation. We are a Deeside electrical contractor that has been installing solar since 2010, at every scale.

We know the region's roofs
Slate roofs in Gwynedd and Conwy, coastal wind loading on Anglesey and the Dee estuary, in-roof systems for sensitive landscapes. We specify mounting and fixings for the building, not from a catalogue.
MCS certified and NICEIC approved
MCS is what makes your system eligible for Smart Export Guarantee payments. NICEIC approval means the electrical side, from consumer unit to earthing, is done by qualified electricians and certified to BS 7671.
SP Energy Networks handled
Every North Wales connection goes through SP Energy Networks. We submit G98 notifications and G99 applications, and we know how long they really take on constrained rural circuits.
Commercial scale
From a 41.85kWp canopy to a 2.2MWp distribution centre. If your business is on Deeside Industrial Park, Wrexham Industrial Estate, St Asaph Business Park or a farm in Powys, we have done something similar.
Batteries and EV charging too
We install battery storage and are OZEV approved EV charger installers, so your solar, battery and car charger are designed together and fitted by one contractor.
One hour from most of North Wales
Queensferry is on the A494 beside the A55. Wrexham is 20 minutes, Denbigh 40, Llandudno 50, Bangor just over an hour. Surveys are quick and warranty visits are not a problem.
Local Considerations

What Changes When You Install Solar in North Wales

A few things are specific to this part of the country. We cover them at survey so the quote is right first time.

  • Planning in Wales — most roof-mounted home systems are permitted development, but listed buildings, conservation areas and the national park have their own rules. We check with the local authority or Eryri National Park before quoting.
  • Welsh Government support — some households qualify for help through the Warm Homes Nest scheme. We will tell you if you do rather than quote you for something you could get funded.
  • 0% VAT until 31 March 2027 — on domestic solar and battery installations. Our quotes show it.
  • Smart Export Guarantee — rates vary by supplier. You need an MCS certificate to register, which we issue at commissioning.
  • Coastal and upland exposure — higher wind loads on Anglesey, the Llŷn and the Dee estuary mean mounting systems are specified to the site, not a default.
  • Rural grid capacity — larger systems in Denbighshire, Conwy and Gwynedd can hit export limits. We apply to SP Energy Networks early and design around the answer.

Design & DNO
Panel layout, inverter and battery sizing, then the G98 notification or G99 application to SP Energy Networks, submitted by us.
Installation
Scaffold, mounting, panels, inverter and all electrical work by our own NICEIC approved electricians. One to two days for most homes; phased for businesses.
Commission & MCS
Testing to BS 7671, monitoring app set up, MCS certificate issued and your Smart Export Guarantee paperwork explained.

North Wales Solar FAQs

Questions We Get Asked Across North Wales

Are solar panels worth it in North Wales with our weather?

Yes. Solar PV generates from daylight, not heat, and a south-facing roof in North Wales typically yields around 900 to 1,000kWh per kWp a year, close to the UK average. A 4kWp system producing 3,600 to 4,000kWh a year offsets a large share of a typical household's electricity. Rain actually keeps panels clean. The real variables are orientation, pitch and shading, which we measure at survey rather than estimate.

How much does a home solar system cost in North Wales?

Most home systems we install cost between £4,500 and £10,000 at 0% VAT: roughly £4,500 to £5,500 for 3kW, £6,500 to £7,250 for 4kW, £7,250 to £9,000 for 5kW and £9,000 to £10,000 for 6kW. Adding a battery starts from around £3,000 for 5kWh. Prices were checked in November 2026. You get a fixed written quote after survey, with a generation and payback projection for your roof.

Do I need planning permission for solar panels in Wales?

Usually not for a home. Roof-mounted solar is permitted development in Wales provided the panels do not project more than 200mm from the roof and the property is not listed. Conservation areas and Eryri (Snowdonia) National Park have extra conditions, and commercial arrays above the permitted thresholds need an application. We confirm this before you commit.

Which DNO covers North Wales and does it slow things down?

SP Energy Networks is the distribution network operator for all of North Wales. Systems up to 3.68kW per phase are notified after installation under G98; anything larger needs a G99 application before work starts, which can take several weeks, longer on constrained rural circuits. We submit the paperwork and program the installation around the response.

Can you install commercial solar on our business in North Wales?

Yes. We have installed rooftop PV on industrial units, a glass manufacturing plant, a national park headquarters, a 250kWp in-roof array and multi-site retail estates. Commercial systems are quoted with a half-hourly consumption model so the array is sized to what you actually use on site, and we handle the G99 application and any export limitation SP Energy Networks requires.
