This list is not exhaustive and does not constitute an endorsement. There are many excellent SEAI-registered solar companies serving Dublin beyond those listed here. We recommend using the SEAI's official register to verify any company and always getting at least 3 quotes before making a decision.
How to Choose the Right Installer
SEAI Registration is Non-Negotiable
Only use an installer on the SEAI Registered Solar PV Company list. This is mandatory to qualify for the €1,800 grant. You can check any company's registration on the SEAI website.
Get At Least 3 Quotes
Prices in Dublin vary by €2,000–€3,000 for the same system. Getting 3 quotes lets you compare fairly and spot outliers. Make sure each quote specifies the exact panel brand, inverter model, and what's included.
Check What's Included in the Quote
Watch for these common exclusions that add €300–€700 to your final bill:
- Scaffolding — essential for most Dublin homes
- BER assessment — required for the SEAI grant
- ESB Networks NC6 form — needed to sell electricity back to the grid
- SEAI grant application — good installers handle this for you
- Monitoring system — lets you track production on your phone
Understand the Warranties
You need three types of warranty:
- Panel warranty: 25–30 years from the manufacturer
- Inverter warranty: 5–12 years standard (some premium models offer 25 years)
- Workmanship warranty: 5–10 years from the installer

Dublin-Specific Considerations for Solar
- Shading from neighbours: Semi-detached and terraced houses in Dublin suburbs often have shading from adjacent buildings or mature trees. Ask your installer about shade analysis — this affects which inverter type you need.
- Roof space on semis: A typical 3-bed semi in Dublin (Lucan, Swords, Tallaght, Blanchardstown) has room for 8–12 panels on the south-facing roof.
- Scaffolding access: Tight spaces between houses in Dublin estates can affect scaffolding requirements.
- Planning permission: Not needed since 2022 for most homes. Check with Dublin City Council if your home is in an Architectural Conservation Area (parts of Dublin 2, 4, 6, and 8).
- Smart meters: ESB Networks is rolling out smart meters across Dublin. You'll need one to sell electricity back to the grid.
Red Flags to Watch Out For
- Not SEAI-registered: No registration = no grant. Always verify on the SEAI website.
- Pressure selling: "This price is only valid today" or aggressive door-to-door sales. Walk away.
- No site survey: Any installer quoting without visiting your property is guessing.
- No written contract: SEAI requires a written contract. They provide a sample contract template.
- Vague about equipment: If they won't specify the exact panel and inverter brand/model, that's a red flag.
- Full payment upfront: A 10–30% deposit is normal. 100% before installation is not.
Frequently Asked Questions
How much do solar panels cost in Dublin?
A typical 4 kWp system (10 panels) costs €6,800–€8,800 before the SEAI grant, or €5,000–€7,000 after the €1,800 grant. Dublin prices are slightly above the national average due to higher overheads.
How many solar panels do I need for a 3-bed semi in Dublin?
Most 3-bed semis need 8–10 panels (3.5–4.5 kWp), covering 60–80% of average electricity usage. Your installer will size the system based on your actual bills and roof space.
Are solar panels worth it in Dublin?
Yes. A 4 kWp system saves €800–€1,200 per year and pays for itself in 5–7 years. After that, the electricity is essentially free for another 18–23 years.
Do I need planning permission for solar panels in Dublin?
No, for most homes since 2022. Exceptions for protected structures or homes in Architectural Conservation Areas — check with Dublin City Council if unsure.
How do I check if a solar company is SEAI-registered?
Visit seai.ie and search their Solar PV Company register. You can filter by county. Only companies on this list can complete grant-eligible work.
What's the best solar panel brand for Dublin homes?
Premium brands like SunPower and LG offer top efficiency. Mid-range brands like Trina Solar, JA Solar, and Canadian Solar offer excellent value. Your installer should explain their recommendation and why.
Can I install solar panels on a semi-detached house in Dublin?
Absolutely. Most Dublin semis have enough south-facing roof space for 8–12 panels. East/west facing roofs work too, producing about 80–85% of a south-facing system. Shading from neighbouring houses can be managed with the right inverter setup.
How long does installation take in Dublin?
A standard residential installation takes 1–2 days. Minimal disruption inside the house — most work is on the roof and at the fuse board.
