“The quote came back within a day and was cheaper than two others we'd gotten locally in Mayo. Install took a day and a half at our house near Ballina. Genuinely painless from start to finish.”

Reviews
What Mayo homeowners say
★★★★★
“From the first survey to the BER cert, the whole Mayo installation was done inside a month. On bright days we're exporting to the grid and actually getting paid on our bill. Should have done it years ago.”
★★★★★
“Very impressed with the installer we were matched with in Mayo. No pushy sales talk — just a clear quote, a clean install on our roof in Swinford, and an app that shows exactly what we're generating.”
Solar in the West
Why solar works so well in Mayo
From the pilgrim path up Croagh Patrick to the cliffs of Achill Island, Mayo is pure Wild Atlantic Way — and its skies still deliver an estimated 1,250–1,350 hours of sunshine a year. Long summer daylight on Ireland's west coast means June generation runs from dawn past 10pm, and the county's cool breezes keep panels operating at peak efficiency. Homes around Castlebar, Westport and Ballina are leading one of the strongest solar surges in Connacht.
A standard grant-aided 4kWp system in Mayo typically generates 3,200–3,800 kWh a year — a large share of the average home's electricity — and anything you don't use is exported to the grid and paid on your bill under the microgeneration scheme. With 0% VAT and the SEAI grant, most Mayo installations pay for themselves in five to seven years, then keep producing for decades.

The process
How your Mayo solar installation works
- Request your free quote
Tell us about your home in Mayo — roof type, electricity usage and Eircode. We match you with vetted, SEAI-registered installers covering your area and you'll have quotes to compare within days.
- Home survey & system design
Your installer surveys the roof (in person or by satellite imagery), checks orientation and shading, and designs a system sized to your usage — typically 8 to 14 panels for Mayo homes.
- SEAI grant application
Apply for the Solar Electricity Grant of up to €1,800 with your installer's details. Approval usually arrives quickly, and no work can start until your Letter of Offer is in hand — we make sure of it.
- ESB Networks connection
Your installer applies to ESB Networks (form NC6) to connect your system to the grid — this also sets you up to be paid for the electricity you export on sunny Mayo days.
- Installation day
Scaffolding up, panels mounted, inverter wired, system commissioned — typically one to two days on site. Your installer walks you through the monitoring app before they leave.
- BER assessment & grant payment
A registered assessor completes your post-works BER, the paperwork goes to SEAI, and your grant is paid. From first quote to money-in-bank is usually four to eight weeks.
FAQs
Solar panel questions from Mayo homeowners
How much do solar panels cost in Mayo?
A typical 8–12 panel (3.5–5kWp) home system in Mayo costs roughly €6,500–€10,000 before supports in 2026. With the SEAI grant of up to €1,800 and 0% VAT on residential solar, most Mayo homeowners end up paying around €5,000–€8,000 net. Your exact price depends on roof type, scaffolding access and whether you add a battery — which is exactly why we recommend comparing quotes.
Is there enough sunshine in Mayo for solar panels to work?
Yes. Mayo receives an estimated 1,300 hours of sunshine a year, and solar panels generate from daylight, not heat — they actually run more efficiently in Ireland's cool climate than in hot countries. A well-sited 4kWp system in Mayo will typically generate 3,200–3,800 kWh a year, covering a large share of an average home's usage.
What SEAI grant can I get for solar panels in Mayo?
Homeowners in Mayo can claim the SEAI Solar Electricity Grant of up to €1,800 (for systems of 4kWp or more) in 2026, provided the home was built and occupied before 2021 and hasn't received the grant before. You must have grant approval before installation starts. Our partner installers are all SEAI-registered and handle the application with you.
Do I need planning permission for solar panels in Mayo?
In almost all cases, no. Rooftop solar on houses is exempt from planning permission in Ireland since the 2022 exemption updates removed the old size limits. Exceptions apply for protected structures and some architectural conservation areas — if your Mayo home falls into one of those categories, we'll flag it at survey stage.
How long does a solar installation take in Mayo?
The physical installation is usually one to two days. End to end — quote, SEAI grant approval, ESB Networks notification, installation and BER assessment — most Mayo projects complete within four to eight weeks. Grant approval must be in place before work begins, so getting your quote early is the key step.
