What Donegal homeowners say
★★★★★
“We had a 10-panel system installed on our home in Letterkenny last spring and the difference has been unreal — our summer bills dropped by more than half. The crew arrived when they said they would and left the place spotless.”
★★★★★
“Got three quotes through the site for our Donegal installation and picked the best value. They handled all the SEAI grant paperwork for us and the €1,800 came through without a hitch. Couldn't recommend it more.”

Why solar works so well in Donegal
Donegal is Ireland's wild north-west — Errigal, Slieve League's towering sea cliffs, Glenveagh National Park — and yes, solar works here too. The county receives an estimated 1,150–1,250 hours of sunshine annually, and long summer days at this latitude mean generation from before 5am to after 10pm in June. Modern panels are designed for exactly this kind of bright, cool, changeable climate, and homes around Letterkenny and the Inishowen Peninsula are proving the point.
A standard grant-aided 4kWp system in Donegal 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 Donegal installations pay for themselves in five to seven years, then keep producing for decades.

The process
How your Donegal solar installation works
- Request your free quote
Tell us about your home in Donegal — 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 Donegal 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 Donegal 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 Donegal homeowners
How much do solar panels cost in Donegal?
A typical 8–12 panel (3.5–5kWp) home system in Donegal 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 Donegal 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 Donegal for solar panels to work?
Yes. Donegal receives an estimated 1,200 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 Donegal 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 Donegal?
Homeowners in Donegal 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 Donegal?
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 Donegal home falls into one of those categories, we'll flag it at survey stage.
How long does a solar installation take in Donegal?
The physical installation is usually one to two days. End to end — quote, SEAI grant approval, ESB Networks notification, installation and BER assessment — most Donegal 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.
