Solar Panels Wexford — Costs, Grants & Local Installers

Wexford is the sunniest county in Ireland for solar. The southeast corner consistently sees 1,050–1,100 kWh per kWp per year — the best yield in the country — which is why solar payback periods here are shorter than anywhere else in Ireland.

Does solar work in Wexford?

Wexford is the sunniest county in Ireland for solar. The southeast corner consistently sees 1,050–1,100 kWh per kWp per year — the best yield in the country — which is why solar payback periods here are shorter than anywhere else in Ireland.

Solar panels generate electricity from daylight, not just direct sunshine — so Ireland's cloud cover matters less than most people assume. Every Irish county gets 900–1,100 kWh of solar yield per kWp installed each year. The south and east get slightly more; Atlantic counties like Galway, Mayo, and Donegal get slightly less. But across the country, the economics work — especially combined with the SEAI grant and the Microgeneration Support Scheme.

Ireland's electricity prices are among the highest in Europe. Every kWh you generate yourself is a kWh you're not buying at 30–38 cent from your supplier. That's the real case for solar in Wexford — and it's strengthened by the SEAI grant covering a meaningful share of the upfront cost.

What does it cost?

A typical 3–4kWp solar system costs €8,000–€12,000 installed before the SEAI grant. The spread reflects roof complexity, panel quality, inverter choice, and scaffolding. Always get three quotes — prices vary more than you'd expect.

Grant is paid directly to your installer. You must use an SEAI-registered contractor and apply before installation begins. Full grant detail on the SEAI grants page →

No inflation assumptions. Actual benefit varies by system size, usage, and supplier export rate.

Getting paid for what you export

Under the Microgeneration Support Scheme (MSS), your electricity supplier pays you for surplus electricity you send back to the grid. Rates vary by supplier but are typically 18–24c/kWh. Electric Ireland, Energia, SSE Airtricity, and others all offer export tariffs — check your supplier's current rate before installing.

You'll need a grid connection from ESB Networks to participate. Allow 3–6 months from application to connection. Your installer should handle the application — confirm this is included before signing any contract.

Planning permission

Solar panels on most Irish homes are exempted development — you don't need to apply for planning permission. The exemption covers panels on the roof or within the curtilage of a house, subject to conditions on panel area and visual impact.

Exceptions apply to protected structures and certain Architectural Conservation Areas. Check with your local council if your property is listed, or visit planning.ie for the full rules.

Finding a registered installer in Wexford

Always use the SEAI registered contractor list — you must use a registered installer to claim the grant, and registration gives you some assurance of competence and accountability.

Questions to ask every installer

  • How many kWp do you recommend for my home, and why?
  • What inverter brand and model are you using?
  • Is scaffolding and grid connection registration included in this quote?
  • Are you SEAI-registered, and will you handle the grant application?
  • What is your workmanship warranty, and what does it cover?
  • Can you give me two or three references from recent installs in this county?

How much does solar cost in Wexford?

What SEAI grant can I claim in Wexford?

The SEAI Solar PV grant covers €700/kWp for the first 2kWp and €200/kWp after that, up to €1,800 for a 4kWp system. You must use a registered SEAI contractor and apply before installation starts.

Do I need planning permission for solar in Wexford?

In most cases, no. Solar on a standard residential roof is exempted development in Ireland. Exceptions apply to protected structures and conservation areas. Check with Wexford County Council if your property is listed.

How do I find a solar installer in Wexford?

Use the SEAI registered contractor search at seai.ie — filter by Solar PV and Wexford. Confirm the contractor's registration is current before signing. Always get at least three quotes.

How much can I earn from exporting solar electricity in Wexford?

Under the Microgeneration Support Scheme, your supplier pays you for electricity exported to the grid — typically 18–24c/kWh. Given Wexford's high solar yield, systems here tend to generate more exportable surplus than most other counties.
