Solar panels Dublin: independent advice and quotes for homes, apartments and businesses
Dublin is the second-best county in Ireland for solar yield. We explain the four councils’ rules, the airport zones and the grants, then match you with SEAI-registered installers.

Solar panels Dublin homeowners can use aren’t only for detached houses with big south-facing roofs. The county also has red-brick terraces, apartment blocks run by management companies, conservation areas and several airport and aerodrome safeguarding zones. This page covers how solar works across all of them, and how to get quotes from SEAI-registered installers.
Strong yield
PureVolt’s county table puts Dublin second only to Cork, at 972 kWh per kWp a year, 6.4% above the national average.
Room to grow
In April 2022, 27,325 Dublin homes had solar panels: 5% of occupied dwellings, against 6% nationally (CSO Census 2022).
Four councils, one rulebook
Dublin City, Fingal, South Dublin and Dún Laoghaire-Rathdown all apply the same national solar exemptions, but each keeps its own records of protected structures and conservation areas.
How much will solar panels generate in Dublin?
PureVolt modelled one representative point per county with the EU’s PVGIS tool (SARAH-3 satellite data), using panels at 30°, facing due south, with standard losses and no shading. Dublin comes out at 972 kWh per kWp per year, compared with a national average of 913.
In practice, Dublin roofs vary more than the county figure suggests. A terrace with an east-west roof, a chimney stack and a neighbour’s extension casting shade will produce less than the model; an open, south-facing suburban roof may match it. Ask installers to show you a shading assessment for your own roof.

Illustrative: a 4 kWp home system in Dublin
4 kWp × 972 kWh/kWp ≈ 3,888 kWh a year under ideal conditions.
The CRU’s average household electricity use is 4,200 kWh a year (via bonkers.ie). How much of your solar you use at home depends on whether someone’s in during the day, an EV or heat pump, and whether you add a battery.

Planning permission for solar panels in Dublin
Your planning authority depends on where you live: Dublin City Council, Fingal County Council, South Dublin County Council or Dún Laoghaire-Rathdown County Council. All four apply the exemptions in S.I. No. 493 of 2022.
Houses (including terraces)
No limit on rooftop panel area. Panels can sit up to 15cm off a pitched roof (50cm on a flat roof) and must be at least 50cm from the roof edge. Free-standing panels in the garden are capped at 25m² and 2.5m high, can’t go forward of the front wall, and must leave at least 25m² of private open space. Wall-mounted panels need permission.
Apartment buildings
The house exemption does not cover apartments, but the 2022 rules added a separate class for apartment buildings with its own conditions (Fieldfisher summary). It’s the management company or building owner, not an individual resident, who usually decides on a shared roof.
Businesses and other buildings
Rooftop solar on business, industrial, school and community buildings is exempt with no area limit outside a Solar Safeguarding Zone. Inside one, it’s capped at 300m² per roof, and the council must be told within 4 weeks of starting.
Airport and aerodrome zones in Dublin
Solar Safeguarding Zones are areas around airports, aerodromes and helipads where glint and glare could affect aviation (gov.ie). S.I. No. 492 of 2022 lists nine that touch Dublin’s four councils: Dublin Airport (Dublin City and Fingal), Weston Airport and Baldonnel (both South Dublin and Kildare), Gormanston (Fingal and Meath), Beaumont and Phoenix Park (Dublin City and Fingal), Kilmainham (Dublin City), Rathmines (Dublin City, Dún Laoghaire-Rathdown and South Dublin) and Tallaght University Hospital (South Dublin).
Houses are not affected: there is no rooftop limit on a house inside or outside an SSZ. The 300m² cap matters for apartment blocks, offices, warehouses and other non-house buildings near those sites.
Protected structures and ACAs
Every Dublin council keeps a Record of Protected Structures and designates Architectural Conservation Areas. In the city, Dublin City Council’s Conservation Office designates ACAs and manages the Record of Protected Structures. The solar exemptions are subject to the general restrictions on protected structures and ACAs, and free-standing panels in an ACA are only exempt if they wouldn’t materially affect the area’s character. If your Georgian or Victorian house is a protected structure, ask the council for a Section 57 declaration first.
Summary only, not legal advice. Sources: S.I. 493/2022, S.I. 492/2022, gov.ie.
Apartments, management companies and terraced roofs
Dublin’s housing stock grew to 565,321 homes in 2022: 250,632 in Dublin City, 115,358 in Fingal, 106,074 in South Dublin and 93,257 in Dún Laoghaire-Rathdown (CSO). If yours is an apartment or a terrace, solar takes a little more planning.
Apartments: SEAI lists owner management companies among the eligible applicants for its domestic solar grant. Only the OMC or its property management agency can create the application, and it needs the OMC’s written authorisation (SEAI). If you live in an apartment, the first step is usually raising it with your management company or at the AGM.
Terraces: the 50cm edge rule, chimneys, rooflights and dormers can limit how many panels fit on a narrow terraced roof. An installer can lay out a small array to suit and tell you whether a battery makes sense for your usage.
Dublin businesses
Offices, retail units, warehouses and schools can use the SEAI business grant. If your building is near Dublin Airport, Weston or Baldonnel, check the SSZ cap before sizing a large roof array. See industries we service.
Farms in north County Dublin
If you farm in north County Dublin, TAMS 3 and the SEAI business grant both apply; see our farm solar guide.

How Solar123 works
Solar123 is an independent advice and quote-matching service. We don’t install anything ourselves: with your consent, we pass your enquiry to SEAI-registered installers who cover Dublin, and they survey and quote.
Your Eircode, house or apartment type, roof direction, rough annual electricity use, and whether you’re an owner, a management company or a business.
We talk you through grants, planning and battery options so you know what to ask. See our battery storage advice if you’re weighing up storage.
They check your roof, shading and electrics and give you a written price. Use our guide to comparing solar quotes to line them up like for like.
No obligation. If you go ahead, your installer and SEAI set out the grant steps. Ready now? Request a quote.
Solar panels Dublin FAQs
Can I put solar panels on my apartment in Dublin?
Usually not on your own: a shared roof is controlled by the owner management company, which can apply for the SEAI domestic grant with written authorisation. Apartment buildings have their own planning exemption class with separate conditions.
I live near Dublin Airport. Can I still get solar panels on my house?
Yes. Houses are not restricted by Solar Safeguarding Zones. The 300m² roof cap applies to non-house buildings such as apartment blocks, offices and warehouses.
Will solar work on a terraced house in Dublin?
Often, yes, but fewer panels may fit once the 50cm edge rule, chimneys and rooflights are allowed for. An installer can tell you what fits and what it would produce.
My house is in an Architectural Conservation Area. Do I need permission?
Rooftop panels on a house are generally exempt, but free-standing panels in an ACA are only exempt if they don’t materially affect its character. If your house is a protected structure, get a Section 57 declaration first.
How much will 4 kWp produce in Dublin?
As an illustration, about 3,888 kWh a year at PureVolt’s Dublin figure of 972 kWh per kWp, assuming a south-facing 30° roof with no shading.
Is Solar123 an installer?
No. We give free advice and, with your consent, pass your enquiry to SEAI-registered installers who survey and quote.
