Solar panels in Wrexham.
Solar panels in Wrexham start with the roof: Wrexham is 17 miles from our Ellesmere Port base, in Wrexham’s planning area, and by the PVGIS model a south-facing roof here makes about 961 kWh a year for every kWp of panels, about 1% more than the same roof at our Ellesmere Port base.
In short
PVGIS puts a south-facing Wrexham roof at 961 kWh for each kWp in an average year. Of the homes near the centre, 82% are houses with their own roof and 18% are flats (2021 Census). Solar on a house here is usually permitted development, VAT on panels from one firm is 0% to the end of March 2027, and we notify the SP Manweb network. The figures, with their sources.

Of what the roof generates
Worked out for a typical Cheshire roof at the pitch and aspect you picked, on a unit rate of 28p and an export rate of 6.5p — rates this tool assumes, dated September 2026, rather than any tariff you have been offered. Nothing here is a quotation: your roof, your shading and how much electricity you use while the sun is up are what the survey settles.
Take the figures with you.
Copy what the studio worked out for your roof, or send it straight to us with a survey request. None of it is a quote: the survey replaces every figure above with your own.
Every assumption behind the numbers
- Unit rate
- 28p for every unit (kWh) you’d otherwise buy from the grid.
- Export rate
- 6.5p for every unit the house and battery can’t use and send back to the grid.
- Your yearly use
- Worked out from your monthly bill at the 28p unit rate, after a standing charge of about 36p a day — and never less than 1,100 kWh a year.
- What a panel makes
- Each panel is 440 W (0.44 kWp). A kWp makes 880 kWh a year facing south, 760 facing east–west and 620 facing north-ish. For this part of Cheshire the EU’s PVGIS model gives 951 for a south roof at a typical pitch — the studio stays below it.
- Pitch
- Shallow (28°) makes 95% of a typical 38° roof; steep (48°) makes 97%.
- Shading
- A bit of shade costs 10%; heavy shade costs 24%.
- How many panels
- Two rows, growing with your bill from three columns to eight — six panels up to sixteen.
- How much you use yourself
- The share of what the roof makes that the house uses: 30% if you’re usually out, 46% in and out, 62% usually home. A battery adds 24 points and a car charger 6, up to 86% — and never more than 62% of your whole year’s use.
- Saving
- The units you use yourself at 28p, plus the units you export at 6.5p.
- Payback
- The yearly saving set against what a system like the one you’ve built typically costs to install: a base figure, an amount for each panel, and more again for a battery or a charger. The answer is held between 4 and 25 years. The studio never shows that cost, because only a survey can price your roof — so treat the years as a rough guide, not a figure to hold us to.
Monthly and yearly sunshine for this area: PVGIS 5.2, EU Joint Research Centre. The unit rate, the export rate and the standing charge are the studio’s own assumptions, set in September 2026 — not a tariff we have quoted you. Your own rates are on your bill, and a survey works from those.
Census 2021, around the centre
Wrexham’s homes and their roofs.
Wrexham’s central 6 Census neighbourhoods, counted inside Wrexham, held 21,905 households in 2021.
- 82% live in a house with a roof of its own27% detached, 33% semi-detached and 21% terraced. A semi or a terrace usually has one main roof slope facing the street and one facing the garden, so the direction of the house decides which side the panels go.
- 18% live in a flatA block’s roof is shared and belongs to the freeholder, so panels on a flat start with their permission, not ours.
- 57% own their home32% outright and 24% with a mortgage. Panels stay with the house, so they suit someone planning to stay, or a buyer who values a lower bill.

- 961 kWh per kWp in a typical yearThat puts Wrexham 1% above the figure for our base. As an illustration, a 4 kWp south-facing array in Wrexham would make roughly 3,840 kWh a year.
- May is the strongest monthAbout 120 kWh per kWp, against 32 in December. May to July make about 37% of the year between them.
Modelled with the JRC’s PVGIS tool, version 5.2. A shaded roof, or one facing east or west, makes less; the roof studio above runs the same model for your own roof and bill. Month by month, the dark half of the year: whether solar panels work in winter.
The wires
Connecting panels to the grid in Wrexham.
Wrexham is on SP Energy Networks’ SP Manweb network, the licence area SPEN describes as covering “North Wales, Merseyside, Cheshire and North Shropshire”. A single generator under 16A per phase (3.68kW) is notified under G98 “before or at the time of commissioning”, and the commissioning confirmation is due “within 30 days of commissioning”; anything larger goes through a G99 application.

Planning
Planning rules in Wrexham for rooftop solar.
Wrexham is in Wales, where planning is separate and England’s August 2026 changes do not apply. Welsh Government guidance is that panels on a wall or pitched roof should project no more than 200mm, and a flat-roof array may not sit within 1 metre of the roof edge or stand more than 1 metre above it.
gov.walesThere are currently 23 designated conservation areas within the County Borough. Wrexham County Borough Council’s page lists 4 conservation areas in Wrexham: Wrexham Town Centre; Fairy Road (Wrexham); Grosvenor Road (Wrexham); Salisbury Park (Wrexham). Each area has its own page with a map and a Character Assessment and Management Plan.

What goes with the panels
Batteries and chargers for Wrexham roofs.
Which one suits depends on the space, the house’s usage and whether there are panels already.

A battery stores the surplus the panels make at midday; a solar-aware charger puts it into the car. Both are on our home battery storage installation and EV charger installation pages.
Straight answers
When we’d tell you not to, in Wrexham.
A survey that ends in “not this house” is a good survey. These are the usual reasons.
- A roof that faces north, or sits in heavy shadeThe PVGIS figure on this page is for a south-facing roof. A north-facing slope or a roof under tall trees or a neighbour’s gable can make so much less that the numbers stop working, and we would say so at the survey rather than fit it anyway.
- A flat, rather than a houseAbout 18% of households around Wrexham’s centre lived in a flat in 2021. The roof of a block is the freeholder’s, which means their consent and usually a lease variation come first; it can be done, but it is not a quick job.
- A listed house, or a conservation-area frontageA listed house needs consent before anything goes on the roof, and in a conservation area the street-facing side has limits. Wrexham itself has 4 conservation areas on Wrexham’s list.
- A roof that needs replacing soonPanels last decades. If the roof covering is near the end of its life, re-roofing first and fitting the panels once is cheaper than lifting and refitting them later.

- 0% VAT until 31 March 2027Residential solar panels, batteries and diverters fitted by an installer who both supplies and installs them are zero-rated for VAT from 1 May 2023 until 31 March 2027, when the rate reverts to 5%. HMRC VAT Notice 708/6 (energy-saving materials).
- Paid for what you exportUnder the Smart Export Guarantee your supplier pays for what the panels send back to the grid. Rates and the rules: the Smart Export Guarantee explained.

Solar panels in Wrexham: what people ask.
If yours isn’t here, give us a ring and ask, or see every question.
Over a year, PVGIS estimates 961 kWh per kWp for a south-facing, 38° roof at Wrexham’s coordinates, ranging from 32 kWh in December up to 120 kWh in May. A roof facing east or west, or one with shade, makes less, which is why the survey looks at your roof rather than the town average.
Usually not, but the Welsh rules apply in Wrexham: panels on a pitched roof or wall should stand no more than 200mm proud, and a flat-roof array keeps a metre back from the edge. A listed building or a conservation area changes that, and Wrexham County Borough Council is the planning authority.
The SP Manweb network. Every system is notified to that operator, and we send the paperwork for you.
In the 2021 Census, Wrexham’s central neighbourhoods had 27% of households in detached houses, 33% in semis and 21% in terraces: 82% with a roof of their own. Whether one particular roof works comes down to its direction, its shading and its condition, which is what the survey checks.
There is no general grant for solar panels in Wrexham. What applies to every home is 0% VAT on panels supplied and fitted by one firm until 31 March 2027, and export payments under the Smart Export Guarantee.
Wrexham County Borough Council. Its own conservation-area page, linked in the planning section above, is the place to check a particular address before the survey; if the house is listed or the roof is flat, mention it when you get in touch.

Yes, but far less: what a south-facing roof in Cheshire makes month by month, why winter is a small slice of the year, and what a battery does in December.
