Solar panels in Wrexham

The Wrexham council area had 135,117 residents at the 2021 census. North Wales sits on the SP Manweb network, not the South Wales one. This page covers the points that change when you go solar in this part of Wales.

Solar Cymru is an independent guide and referral service. We do not fit panels, but we can connect you with MCS-certified installers.

The grid in Wrexham: SP Energy Networks

SP Energy Networks, through SP Manweb, serves North Wales. Its statement describes an area that borders National Grid Electricity Distribution to the south. Because the boundary matters, confirm the operator for your postcode with the Energy Networks Association finder.

The same national rules apply on both networks. A system at or below 16 A per phase follows G98. That is 3.68 kW on single-phase. The installer must then tell the operator within 28 days. Larger systems need G99 approval first. Our post on G98 and G99 for Welsh solar explains the difference.

One caution applies. Network policies differ between operators, and a free reinforcement policy that one operator offers may not apply to the other. Ask your installer what the local operator expects.

How much a Wrexham roof makes

PVGIS gives about 970 kWh a year for each kWp on a south-facing roof at 35 degrees. That is lower than the south coast, yet still a strong return. A 4 kWp array would make around 3,900 kWh.

A lower yield makes orientation and shade checks matter more. For instance, an east or west roof loses about 15 to 20 percent against south. Our yield guide for Wales shows how installers model those losses.

Planning, conservation areas and a World Heritage Site

Wrexham County Borough Council handles planning. Roof panels on a house usually need no application. They must sit within 20 cm of the roof slope and below its highest point. Specifically, they must also limit their effect on the building and the area.

Cadw’s dataset records 23 conservation areas in the Wrexham planning area, including one named Wrexham Town. A wall facing a highway in a conservation area needs planning permission. Meanwhile, Article 4 directions can remove permitted development rights, and the council register will show them.

The Pontcysyllte Aqueduct and Canal World Heritage Site, inscribed in 2009, also affects planning nearby. Wrexham, Denbighshire and Shropshire councils issued joint guidance that treats the site and its setting as a material consideration. If your home lies near it, speak to the council before you commit.

What a Wrexham home pays and saves

Installed costs in 2025-26 ran at roughly £1,400 to £1,950 per kW, based on official statistics. For a typical 4.5 kWp home that points to £6,500 to £8,800. Savings of around £450 to £500 or more a year are realistic if you use much of the power yourself.

Electricity carries 0% VAT between 1 October 2026 and 31 March 2027. As a result, each unit you avoid buying saves slightly less during that window. Home solar itself has 0% VAT until 31 March 2027, so the timing of an order matters.

Why an MCS-certified installer matters

MCS certification is the quality mark for small solar systems. Export payments on systems up to 50 kW need an MCS certificate or an equivalent. Our explainer on MCS certification and your quote shows what to check.

Consumer code membership is now optional for MCS installers. Therefore, ask whether the installer joins RECC or HIES, and how it protects deposits. An electric car owner should also read about charging an EV with solar before choosing a size.

Getting quotes for Wrexham homes
