Solar Panels Wexford 2026: Ireland's Sunniest County for Solar — Costs, Output & Installers

Wexford is Ireland's number one county for solar panels — and it's not close. With a solar yield of 965 kWh/kWp and up to 1,600 sunshine hours per year at Rosslare, Wexford produces more solar electricity per panel than anywhere else in the country. For homeowners in Wexford town, Gorey, Enniscorthy, New Ross, or along the coast, this translates into faster payback, bigger savings, and more value from every panel on your roof.

This guide uses Wexford-specific data — not national averages with a county name swapped in. You'll find real 2026 pricing from installers serving the county, output figures based on southeast irradiance data, and practical advice on navigating the growing number of SEAI-registered companies competing for your business in the Sunny Southeast.

Why Wexford Tops Ireland's Solar Rankings

Wexford's position in the southeast corner of Ireland gives it a double advantage: maximum exposure to the sun's arc across the southern sky, and shelter from the Atlantic weather systems that hammer the west coast. The Blackstairs Mountains along the western border provide a further rain shadow effect, keeping cloud cover lower than inland counties. Here's how Wexford compares:

Metric	Wexford	National Average	Advantage
Sunshine hours/year	1,540–1,600	1,100–1,250	+25–30%
Solar yield (kWh/kWp)	965	884	+9%
Solar irradiance (kWh/m²/yr)	1,060–1,120	950–1,000	+10–12%
Peak sun hours/day (annual avg)	3.0–3.2	2.5–2.8	+12–18%
4 kWp system annual output	3,860–4,300 kWh	3,400–3,800 kWh	+10–15%

In practice, a standard 10-panel (4.1 kWp) system in Wexford generates roughly 3,860–4,300 kWh per year. That's enough to cover 90–100% of the average Irish household's annual electricity consumption of 4,200 kWh. Compare that to Galway (3,400–3,600 kWh) or Donegal (3,200–3,500 kWh), and the southeast advantage becomes very real in euro terms.

What Solar Panels Cost in Wexford in 2026

Wexford benefits from strong installer competition. The county sits at the intersection of several installer territories — companies based in Wexford town, Waterford, Kilkenny, Wicklow, and Dublin all serve the area, driving prices down. Here's what Wexford homeowners are paying in May 2026, after the €1,800 SEAI grant:

House Type	Typical System	Before Grant	After €1,800 Grant	Annual Output
2-bed terrace (town)	6–8 panels / 2.5–3.3 kWp	€4,500–€5,800	€2,700–€4,000	2,400–3,200 kWh
3-bed semi-detached	10–12 panels / 4.1–5.0 kWp	€5,800–€7,600	€4,000–€5,800	3,960–4,800 kWh
4-bed detached	14–18 panels / 5.7–7.4 kWp	€7,800–€10,200	€6,000–€8,400	5,500–7,100 kWh
Bungalow (rural)	12–16 panels / 5.0–6.6 kWp	€6,500–€8,800	€4,700–€7,000	4,800–6,400 kWh
Large system + battery	16–20 panels / 6.6–8.2 kWp + 5–10 kWh	€11,500–€16,500	€9,700–€14,700	6,400–7,900 kWh

Why Wexford pricing is competitive: With 317 SEAI-registered installers serving the county, Wexford is one of the best-served areas outside Dublin. Local companies, combined with installers from Waterford, Kilkenny, and south Dublin, create genuine competition that keeps prices sharp. Rural properties in Wexford also avoid the access premiums common in Dublin (scaffolding restrictions, parking charges, traffic delays).

The Wexford Advantage: Month-by-Month Output

One thing that surprises people about Wexford is how early the solar season starts and how late it runs. While the rest of Ireland is still waiting for spring sunshine, Wexford panels are already generating meaningful power by March. Here's what a typical 4.1 kWp system produces month by month:

Month	Wexford Output (kWh)	National Avg (kWh)	Notes
January	110–130	90–110	Short days, but clearer skies than west
February	160–190	130–160	Days lengthening, output climbing
March	280–320	240–280	Spring arrives early in the southeast
April	390–440	340–390	Strong production begins
May	470–530	410–470	Peak month — long days, strong sun
June	480–540	420–480	Longest days, peak solar
July	450–510	400–460	Slightly cloudier, still strong
August	400–460	350–410	Late summer production holds well
September	290–340	250–300	Wexford's autumn is gentle
October	180–220	150–190	Still useful, especially for self-consumption
November	110–140	90–120	Shorter days, some contribution
December	80–110	65–90	Lowest month, but panels still work
Annual Total	3,400–3,930	2,935–3,460	+15% over national average

The key takeaway: Wexford's solar season effectively runs from March through October — eight productive months. From April to August, a 4 kWp system will generate more electricity than most households consume, meaning significant export income or battery charging.

Real Savings: What Wexford Homeowners Earn Back

Wexford's superior output means faster payback than anywhere else in Ireland. Here's a realistic breakdown for a 3-bed semi with a 4.1 kWp system (10 panels), no battery:

Income/Saving	Annual Value	How It Works
Electricity bill reduction	€780–€1,050	Self-consuming 45–55% of generation at 24c/kWh
Export payments (CEG)	€220–€370	Surplus sold at 18–25c/kWh under Clean Export Guarantee
Total annual benefit	€1,000–€1,420	Higher with smart tariff or load-shifting

With a net cost of €4,000–€5,800 (after the SEAI grant), that gives Wexford homeowners a payback period of 3–5 years — the fastest in Ireland. After payback, you're looking at 20+ years of near-free electricity, with panels warranted for 25–30 years.

The SEAI Grant: How It Works in 2026

Every Wexford homeowner can claim the SEAI solar PV grant, which works on a tiered basis:

• First 2 kWp: €700 per kWp installed = €1,400
• 2 kWp to 4 kWp: €200 per additional kWp = up to €400
• Maximum grant: €1,800 for any system of 4 kWp or larger

The grant is paid after installation by an SEAI-registered installer. Your installer handles most of the paperwork. There's no means test, no income limit, and no BER requirement to get the grant (though your BER will improve as a result). The system must be installed on a home built and occupied before 2021.

Additional financial support includes:

• 0% VAT on solar panel supply and installation (extended through 2026)
• Tax exemption on the first €400 of electricity export income per year (no tax return needed)
• Clean Export Guarantee payments of 18–25c/kWh for surplus electricity sent to the grid

Wexford Town by Town: What's Different?

Wexford is a large county with varied geography. Solar performance varies slightly depending on where you are:

Area	Solar Advantage	Notes
Rosslare / Southeast coast	Best in county (1,600+ sunshine hrs)	Ireland's sunniest recording station; sea breeze keeps panels cool, boosting efficiency
Wexford town	Excellent (1,540+ sunshine hrs)	Good installer availability; mix of terraces and estates with varied roof orientations
Gorey / North Wexford	Very good (1,450–1,500 hrs)	Fast-growing population (trebled since 1996); many newer builds with suitable south-facing roofs
Enniscorthy / Slaney valley	Very good	Sheltered valley location; slightly less wind means panels stay cleaner longer
New Ross / West Wexford	Good (1,400–1,450 hrs)	Slightly more rainfall near Blackstairs Mountains; still well above national average

Even New Ross in the western part of the county gets more sunshine than Dublin, Cork, or Galway. There is genuinely no bad location for solar panels in Wexford.

Does Adding a Battery Make Sense in Wexford?

Because Wexford systems produce so much electricity — often more than you can use during the day — a battery can capture that surplus for evening and night-time use. Here's how the numbers work:

Setup	Self-Consumption	Annual Saving	Added Cost	Extra Payback
Panels only	45–55%	€1,000–€1,420	—	—
Panels + 5 kWh battery	65–75%	€1,250–€1,700	€3,000–€4,500	8–12 years
Panels + 10 kWh battery	75–85%	€1,400–€1,900	€5,000–€7,500	10–15 years

Our advice for most Wexford homeowners: start with panels only. With the Clean Export Guarantee now paying 18–25c/kWh, the financial case for batteries has weakened slightly since export income partially offsets what you'd save by storing. If you work from home or have an electric car to charge, a battery makes more sense because you'll use more of the stored energy at peak times.

How to Choose an Installer in Wexford

With 317 SEAI-registered installers covering Wexford, you have plenty of choice. SEAI recommend getting at least four quotes. Here's what to look for:

• SEAI registration: Non-negotiable. Without it, you won't qualify for the €1,800 grant. Check the SEAI register to verify any installer.
• Local track record: Ask for references in your area. A company that's installed on 50 houses in Wexford estates knows the typical roof structures, planning nuances, and ESB Networks connection process better than a first-time visitor.
• Panel and inverter brands: Look for Tier 1 panels (Trina, JA Solar, Longi, Canadian Solar) and quality inverters (SolarEdge, Enphase, Huawei). Our best solar panels guide ranks the top brands.
• Warranty clarity: You should get a 25–30 year panel performance warranty, 10–15 year inverter warranty, and a separate workmanship warranty from the installer (minimum 5 years, ideally 10+).
• Full quotation: A proper quote should include system size, panel count and brand, inverter brand, mounting system, estimated annual output for your location, and total price before and after grant. Beware of vague or verbal-only quotes.

Planning Permission: Do You Need It?

In most cases, no. Solar panels are exempt development in Ireland under the Planning and Development Regulations, provided:

• Panels don't project more than 15cm above the roof surface
• Panels don't extend above the ridge line
• The total panel area doesn't exceed 12 m² (for a house) or 50 m² (for a commercial building)
• The building is not a protected structure or in an Architectural Conservation Area (ACA)

Most residential systems in Wexford (8–16 panels) fit well within these limits. If you have a protected structure — which is possible in historic Wexford town or Enniscorthy — you'll need planning permission, but it's almost always granted. Your installer will advise.

Wexford vs Other Counties: How Does It Compare?

For homeowners weighing up whether Wexford's solar advantage is real or marketing, here's a direct comparison with other county guides we've published:

County	Solar Yield (kWh/kWp)	Sunshine Hrs/Year	Payback (Years)	Guide
Wexford	965	1,540–1,600	3–5	This page
Waterford	949	1,350–1,465	3.5–5.5	Waterford guide
Kerry	920	1,300–1,450	4–6	Kerry guide
Cork	930	1,300–1,400	4–6	Cork guide
Dublin	905	1,300–1,400	4.5–6.5	Dublin guide
Galway	870	1,150–1,300	5–7	Galway guide
Donegal	840	1,050–1,200	5.5–7.5	Donegal guide

Wexford's 965 kWh/kWp yield is 15% above Donegal and 9% above the national average. Over 25 years, that difference compounds to thousands of euro in extra electricity generated.

Frequently Asked Questions

How many panels does a typical Wexford home need?

A 3-bed semi-detached house in Wexford typically needs 10–12 panels (4.1–5.0 kWp). Because Wexford's yield is higher, you may need slightly fewer panels than someone in the west or midlands to achieve the same output. Use our solar calculator for a personalised estimate.

Is Wexford really the sunniest county in Ireland?

Yes. Rosslare in County Wexford records more sunshine hours than any other Met Éireann station in Ireland — consistently over 1,600 hours per year. The county as a whole averages 1,540+ hours, ahead of Waterford (1,465), Kerry, and Cork.

How long does installation take?

Most Wexford residential installations take 1–2 days once scaffolding is up. The whole process from quote to energisation typically takes 4–8 weeks, including the SEAI grant application, ESB Networks connection, and the installation itself. Read our full installation timeline for the step-by-step.

What about coastal salt air near Rosslare?

Modern solar panels are designed to withstand salt spray and coastal conditions. Look for panels rated IEC 61701 for salt mist corrosion resistance. Coastal properties may benefit from more frequent cleaning (once or twice a year rather than relying solely on rain), but the extra sunshine more than compensates.

Can I get solar panels on a listed building in Wexford?

Wexford town and Enniscorthy have some protected structures and Architectural Conservation Areas (ACAs). If your property is protected, you'll need planning permission for solar panels, but approvals are common — especially for rear-facing or non-visible installations. Talk to Wexford County Council's planning department before committing.

What to Do Next

If you're a Wexford homeowner considering solar panels in 2026, you're in Ireland's best county for it. The combination of top-tier sunshine, competitive installer pricing, the €1,800 SEAI grant, and 0% VAT makes the financial case overwhelming — with payback in as little as 3 years.
