Solar Companies Near Me: How to Find Trusted Installers in Every Irish County (2026)

There are 416 SEAI-registered solar installers operating in Ireland. Most are competent. A handful will leak your roof, undersize your system, and disappear. Here is how to tell the difference — from Donegal to Wexford.

“Solar companies near me” is the single most-searched solar query in Ireland after pricing. And it’s the right instinct: a local installer can be on your roof within a week, knows the planning rules in your council area, and gives you somebody to ring when things go wrong.

But “local” alone is not a quality signal. We’ve audited the SEAI register and 416 active solar PV companies as of mid-2026 — and the gap between the best and the worst, even within the same county, is enormous. Some have done 5,000+ installs and ten years of clean records. Others incorporated three months ago, have zero verified reviews, and are quoting bargain prices that should be a warning.

This guide gives you a concrete process for finding solar installers near you, in your county, with the trust signals that actually matter in 2026.

The short answer: three ways to find local installers

You have three credible places to look. Each has different strengths.

Where to search	What you get	Best for
SEAI register seai.ie	The official authoritative list of grant-eligible installers. Filterable by county.	Verifying that a company you’ve been recommended is grant-eligible
Our county directory getsolarpanels.ie/solar-installers/	All 416 SEAI-registered installers organised by county, with Google ratings, review counts, and verification status pulled from Google Business profiles.	Browsing local options with at-a-glance trust signals
Our quote form getsolarpanels.ie/submit-query/	We route your details to up to three vetted local installers who quote you directly. No middleman fee.	You don’t want to chase down installers individually

The SEAI register is the source of truth for grant eligibility. Anyone NOT on it cannot install your system if you want the €1,800 grant. That’s the floor — not a quality endorsement.

Does “local” actually matter? Yes — here’s why

If you’ve been told local doesn’t matter because all solar installers do the same job, that’s wrong. Five things genuinely change based on geography:

1. Roof type knowledge. Donegal slate, Connemara stone-clad cottages, Dublin pebble-dash semi-d’s, Wicklow new-build estates — each needs a different fixing kit and weatherproofing approach. A Cork installer who’s never touched a Donegal slate roof will hesitate.
2. Local council planning quirks. Most solar PV doesn’t need planning under the 2022 exemption. But Dublin City Council interprets the protected structure overlay differently than, say, Galway County Council. Local installers know which conservation officer to ring.
3. Travel-cost markup. Companies that travel two hours to your site add €200–€600 to the quote (sometimes hidden, sometimes itemised). A local outfit can quote tighter.
4. Service response time. Inverter fault three years in? A 30-minute drive vs. a four-hour drive is the difference between “we’ll be out Tuesday” and “next month, maybe.”
5. Word-of-mouth reputation. A local installer’s reputation lives or dies on what neighbours say. National operators can churn through unhappy customers without consequence.

So “local matters” is real. But local + bad is still bad. Use proximity as a filter, not a decision.

Browse SEAI-registered installers by county

We maintain a directory of every SEAI-registered solar PV company in Ireland, organised by the county where they’re headquartered or have a registered service area. Click your county for the local list with ratings.

Leinster	Munster	Connacht	Ulster (ROI)
Dublin Wicklow Wexford Kildare Meath Louth Carlow Kilkenny Laois Offaly Longford Westmeath	Cork Kerry Limerick Tipperary Waterford Clare	Galway Mayo Sligo Leitrim Roscommon	Donegal Cavan Monaghan

Each county page lists the installers with their Google rating, number of verified reviews, address, phone, and website. We don’t rank them — we present the data so you can judge.

The 8-question vetting checklist (use on every quote)

Local is a starting point. These are the questions that separate a real installer from a chancer. Ask all eight on every quote — on the phone, before they come out for a survey.

Question	Good answer	Bad answer
1. What is your SEAI registration number?	A specific number you can verify on seai.ie in 30 seconds.	“We’re registered, don’t worry about the number.”
2. How many installs have you completed in Ireland?	Specific number, ideally 200+, with the year they started.	“Loads,” “hundreds,” vague hand-waving.
3. Can you give me three references from installs in my area within the last 12 months?	Names, addresses (with permission), and phone numbers of recent customers in your county.	“We can’t share customer details for GDPR.” (Refs given with permission are not a GDPR issue.)
4. Who does the electrical work — in-house RECI-registered electrician or subcontracted?	In-house, named electrician. If subcontracted, named firm with credentials.	“We get a lad in.” (Run.)
5. What is the warranty on the install workmanship, the panels, and the inverter — in writing?	5+ years workmanship, 25+ years panels, 10+ years inverter. Document supplied.	Different numbers each time you ask. Verbal-only.
6. Is scaffolding, BER assessment, ESB Networks notification, and grant paperwork all included in the price?	Yes, itemised on the quote with prices listed.	“Extras will be billed separately.” (Hidden costs incoming.)
7. Will you do a site survey before quoting?	Yes, free, in-person (or detailed video survey for remote properties).	Quote given over the phone from Google Maps screenshots.
8. If something fails in year 5, who do I ring — you or the manufacturer?	“Us first. We handle warranty claims with the manufacturer on your behalf.”	“You contact the manufacturer directly.” (You’ll be on hold for hours.)

If an installer fails three or more of these questions, you have your answer. Move on.

Red flags that override the “local” advantage

These are the warning signs we’ve seen consistently across complaints submitted by Irish homeowners. Any one of them is a deal-breaker, no matter how close the installer is to your house.

• Quotes that are 30%+ below the next-cheapest. A typical 4kWp install in Ireland in 2026 costs €7,500–€9,500 before the €1,800 grant. Anyone quoting under €5,500 is cutting corners somewhere — usually cheap inverter, no MCS-grade fixings, or no workmanship warranty.
• Pressure to sign the same day. “This price is only valid until midnight.” Real installers don’t do this. Cowboys do.
• No physical address, only a mobile number. Look up the company on cro.ie. If they’re not a registered Irish company with a real address, walk.
• Vague panel brand. “Tier 1 panels” or “premium German panels” is not a brand. Get the manufacturer name (JinkoSolar, Longi, JA Solar, REC, etc.) and the wattage in writing.
• No mention of ESB Networks NC6 form. Every grid-connected system in Ireland must be registered with ESB Networks via an NC6 form. If the installer doesn’t mention this, they don’t know what they’re doing.
• Brand-new Google profile with five 5-star reviews dated the same week. Fake review farms operate in this space. Genuine review profiles build up over 1–3 years with a normal star distribution.

When to choose a national operator over a local one

Sometimes a national operator is the better call, despite the “local” instinct. Here’s when:

• You live in a county with thin coverage. Leitrim, Longford, and Monaghan have fewer than 10 SEAI-registered installers each. If none of them check the boxes above, a national operator who’ll travel is the realistic option.
• You want a brand-specific premium product. If you specifically want a Tesla Powerwall 3, an SMA inverter ecosystem, or REC panels with the long warranty, you’re narrowing to a smaller list — brand-trained installers, who often work nationally.
• You’re combining solar with an EV charger and a battery in one project. Multi-product installs benefit from a single contractor with all the certs. Some local installers don’t carry the OZEV-equivalent EV-charger qualifications.
• You want a 10-year-plus install track record. Few local outfits have been running since pre-2018. Some national operators have done 20,000+ installs and have the systems to support that scale.

The county-by-county reality check

Coverage and competition vary wildly. Some counties have a thriving local market; others have effectively two or three installers fighting for everything.

County	Listed installers	Market reality
Dublin	60+	Most competitive market in the country. Get 4–5 quotes; pricing pressure is real.
Cork	40+	Strong local installer base. Look for ones with experience on coastal salt-spray sites.
Galway	25+	Good local coverage; Connemara installs need windload-rated fixings.
Kerry, Donegal, Mayo	10–20 each	Smaller pool. Be willing to wait 4–8 weeks for the better outfits.
Leitrim, Longford, Monaghan, Cavan	Under 10 each	Thin coverage. Consider neighbouring-county installers who travel.

What about Trustpilot and Google reviews?

Reviews are useful but not gospel. A few rules:

• 50+ reviews with 4.5+ stars is meaningful. Anything less is too small a sample to draw conclusions from.
• Read the 1–2 star reviews specifically. Every installer has some unhappy customers. What you want to see is the installer responding professionally, not getting defensive or blaming the customer.
• Check the review dates. A flurry of reviews in one week, then nothing, is a fake-review signature. Real reviews trickle in over years.
• Look for installs near you. A 5-star Cork installer is interesting if you live in Donegal — but not directly relevant to your install.
• Trustpilot and Google Maps disagree? Trust Google Maps more for tradespeople. It’s harder to gamify and reviews tend to come from real customers tagged at the install location.

The minimum quote you should be collecting

You want three quotes. Two is risky (no triangulation); four or more is overkill and starts wasting installer time, which dings your reputation if they all know each other (and in most counties, they do).

Each quote should include, in writing:

1. Panel brand, model, wattage, quantity, and total kWp
2. Inverter brand, model, and capacity (kW)
3. Battery brand, model, and usable kWh (if included)
4. Mounting system brand (K2, Esdec, SunPro, etc.) and roof-fix method
5. DC isolator, AC isolator, surge protection details
6. SEAI grant amount (currently €1,800 for systems 2kWp+) clearly deducted from the total
7. Scaffolding cost (or note that it’s included)
8. BER assessment cost (or included)
9. ESB Networks notification handled by installer
10. Workmanship warranty length
11. Estimated annual generation in kWh based on your roof orientation, pitch, and shading
12. Payment schedule (typically 20–40% deposit, balance on commissioning — never 100% upfront)

If any installer’s quote is missing 3+ of these items, ask them to redo it. If they push back, that’s your answer.

Frequently asked questions

Do I have to use a SEAI-registered installer?

Only if you want the €1,800 SEAI grant. Without grant, you can use anyone competent — but you lose a third of the €5,500–€6,500 net cost of a typical 4kWp install. Almost everyone uses a registered installer.

How long is the typical wait for a local installer?

In 2026, 4–10 weeks for a domestic install in most counties. Shorter in winter, longer in March–September peak season. Anyone offering “next week” in June is either small, hungry, or had a cancellation — ask why.

What if my eircode is on the border of two counties?

Look at installers in both. Many cover a 60–90 minute drive radius. Border-county postcodes (D24/D22 in south Dublin, R51 in Kildare, T56 in West Cork) often get great prices because installers from two counties compete.

Are there any installers I should specifically avoid?

We don’t name specific companies because reputations change and we don’t want to defame a business that may have improved. But: anyone NOT on the SEAI register, anyone with a brand-new Google profile, and anyone whose quote is missing the items listed above should be off your shortlist.

Can I install solar panels myself in Ireland?

You can do the structural work, but the electrical connection MUST be done by a RECI-registered electrician, and you cannot claim the SEAI grant on a DIY install. For grid-connected systems, an unqualified install also voids your home insurance. See our install process guide for the full sequence.

What if the installer goes out of business after install?

Panel and inverter warranties stay with the manufacturer, so those are safe. Workmanship warranty is gone — another reason to use installers with multi-year track records. The SEAI grant scheme also has installer-failure provisions in some cases.

Putting it together

The blunt truth: there is no shortcut to finding a good solar installer. There is a 416-strong list, of which maybe 100 are excellent, 250 are competent, and 60-odd are people you should avoid. Your job is to use proximity to shortlist 5–6, vet them down to 3 with the questions above, and get full written quotes from those three.

If you don’t want to do that yourself, that’s exactly what our quote-matching service does — with installers we’ve already filtered.
