Solar Panels for Apartment Blocks in Ireland (2026): OMC Approval, Planning & Grants

Can apartment blocks in Ireland get solar panels?

Absolutely. Solar panels for apartment blocks in Ireland are no longer a rare pilot project. Rooftop solar now makes up close to 1 GW of Ireland’s solar capacity, and more than 155,000 homes and properties have panels. Apartment dwellers have mostly been left out so far – not because the technology doesn’t work, but because of shared ownership, paperwork and who pays.

The good news: flat apartment roofs are often better for solar than house roofs. There’s no shading from chimneys, panels can be tilted to face south, and a single installation can serve a whole building. And solar works in Irish weather – panels run on daylight, not heat, and actually perform well in the cold. As a rule of thumb, every 1 kWp of panels in Ireland produces roughly 850–900 kWh of electricity a year.

Do apartment blocks need planning permission for solar panels?

In most cases, no. Since October 2022, a dedicated planning exemption – Class 60 of S.I. No. 493/2022 – covers solar panels on the roofs of apartment buildings. If you follow its conditions, the system counts as “exempted development” and you don’t need to apply for planning permission.

The key Class 60 conditions in plain English

• Roof only. The exemption covers panels on the roof of the apartment building (or the roof of an ancillary building in its grounds). Wall-mounted and free-standing systems are not covered.
• Setbacks and height limits. Panels must be kept back from the roof edge and must not rise above set heights – your installer designs around these.
• Mostly for the building. The electricity must be “primarily” used on site – the law defines this as more than 50%.
• No dazzling. If panels cause hazardous glint or glare, the exemption is lost.
• Solar Safeguarding Zones. Near airports and some other sensitive sites, the total panel area is capped at 300 m² and the council must be told in writing within 4 weeks of work starting.

Who has to say yes? The Owners’ Management Company

This is where most apartment solar projects stall – so it’s worth getting right. In a typical Irish development, each owner owns their own apartment, but the roof, walls, wiring and common areas belong to the Owners’ Management Company under the Multi-Unit Developments Act 2011. That means:

• An individual owner usually can’t put their own panels on the shared roof without the OMC’s written permission.
• The OMC board may be able to approve the project itself, or it may need a vote at the AGM – check the company’s constitution and house rules.
• The OMC (or its property management agent, with written authority) is the body that applies for the SEAI grant.

How to win the vote

Owners say yes when the numbers are simple. Bring three things to the meeting: a roof survey and system design, a clear cost per apartment, and the yearly saving on the service charge. Answer the usual worries up front – roof warranty, insurance, maintenance and what happens if the roof needs repairs later. A good installer will help you prepare this pack for free.

4 ways to use solar on an apartment block

The right setup depends on how the building is wired and what the owners want. Here’s how the options compare:

Our advice: start with common-area solar. It’s the cheapest to install, easiest to get approved and every owner benefits equally. Common loads like lifts, emergency lighting and ventilation run every day, so most of the solar power is used on site – which is where the real savings are. Any surplus is sold back to your electricity supplier under the Clean Export Guarantee.

The SEAI solar grant for apartment blocks

Yes, apartment blocks can get the SEAI Solar PV grant. The scheme is open to homeowners, private landlords, Owners’ Management Companies and Approved Housing Bodies. For 2026 the grant is:

Grant rules that catch apartment blocks out

• Apply BEFORE any work starts. You need a grant approval in place first – start early and you lose the grant.
• Building age. The cut-off date was widened in October 2026 so many newer buildings now qualify – check the current date on the SEAI website.
• One grant per MPRN. No previous solar PV funding is allowed at that meter point.
• OMC applications are paper-based. They’re created by the OMC or its property management agency (with written authority), using forms you request from SEAI.
• Registered installer. The work must be done by a company on the SEAI register, and you have 8 months from approval to finish.

Remember, the €1,800 grant is a contribution, not the full cost. On a larger block the grant covers a smaller share – the bigger win is the yearly saving on common-area electricity, plus 0% VAT on qualifying supply-and-install solar for homes.

Costs, savings and payback for an apartment block

Every building is different, so treat this as an illustration, not a quote. Here’s a typical example of common-area solar on a mid-sized block:

Figures are indicative only and depend on roof size, orientation, access, scaffolding, common-area usage and your electricity tariff. Contact us for a free site-specific estimate.

What drives the cost up or down

• Roof access and safety – edge protection, cranes or scaffolding on tall buildings.
• Roof type – flat roofs usually need ballasted frames that don’t pierce the membrane.
• Cable runs – the distance from the roof down to the landlord meter room.
• Structural check – an engineer may need to confirm the roof can carry the load.
• Battery or not – adds cost, but stores more of your own power for evenings.

Who benefits?

Owners get lower service charges and a more valuable, greener building. Landlords get a better BER for their units – which matters more and more for rental rules and buyers. Tenants get a building that’s cheaper to run, which helps keep charges down.

Should an apartment block add a battery?

Many common-area loads (corridor lights, car-park lights, emergency lighting) run in the evening and overnight – exactly when the sun’s gone. A battery stores the midday surplus so the building uses it after dark instead of selling it cheaply to the grid. For apartment blocks we recommend the Sigenergy SigenStor system: it combines the inverter, battery and EV charging in one compact unit, is easy to expand later, and is ideal for a plant room or meter room where space is tight. We also install Tesla, Solis, GoodWe and SAJ.

Step-by-step: getting solar on your apartment block

1. Check the basics. Who owns the roof? Is the building a protected structure? Does it meet the SEAI build-date cut-off?
2. Get a free roof survey. We look at roof space, shading, structure, access and your common-area electricity bills.
3. Get a design and a clear proposal. System size, cost per apartment, expected savings and payback.
4. OMC approval. Board decision or AGM vote, plus written sign-off and any licence terms.
5. Apply for the SEAI grant. The OMC or its managing agent applies and waits for approval – no work before this.
6. Confirm planning. Check the design meets Class 60, and notify the council if you’re in a Solar Safeguarding Zone.
7. Installation. Usually just a few days on a typical block, with minimal disruption to residents.
8. Grid paperwork and switch-on. ESB Networks notification, smart meter for export, and sign up for the Clean Export Guarantee.
9. Claim the grant and monitor. Track generation and savings from your phone and report them at the AGM.

Plug-in balcony solar: where the rules stand in Ireland

If your OMC won’t approve rooftop solar, or you’re renting, plug-in balcony solar is the one to watch. It’s one or two panels clipped to a balcony rail, with a small inverter that plugs straight into a normal wall socket. Your apartment uses the power first, so your bill drops from day one.

Is plug-in solar legal in Ireland?

Not yet, but it’s being worked on. At the moment every grid-connected solar system in Ireland has to be fitted by a registered electrician and notified to ESB Networks. That’s changing:

• Government backing: Energy Minister Darragh O’Brien has said plug-in solar could be a “game changer” for apartments and multi-unit developments, and has asked ESB Networks to draft the rules.
• ESB Networks on board: in July 2026 the Minister told the Dáil that ESB Networks supports small plug-in solar or battery devices up to 800W, with a simple registration process, as long as they meet safety and product standards.
• Neighbours have done it: plug-in solar up to 800W became legal in Great Britain on 27 August 2026 (Northern Ireland isn’t covered yet), and Germany has more than 1.3 million registered plug-in systems.
• Timeline: an ESB Networks-led working group first met in June 2026 and was due to report to the Minister in September. No rules or start date have been published yet. We’ll update this guide the moment it’s official.

Will there be a grant for plug-in solar?

No plug-in solar grant has been announced. There’s political pressure for one (the Green Party, for example, has called for a balcony solar grant), but nothing official yet. Kits are far cheaper than a rooftop system, so the payback can be reasonable even without a grant once they’re allowed.

Is my balcony suitable?

• South-facing is best; east or west works for part of the day; north-facing isn’t worth it.
• Permission: renters will need the landlord’s OK, and owners should check OMC house rules on balconies and façades.
• Buy certified: when the rules land, only buy kits that meet the Irish standard – don’t plug in a cheap import before then.

Solar PPAs for apartment blocks: solar with no upfront cost

If your owners’ management company (OMC) likes the idea of solar but can’t fund it from the sinking fund, a solar Power Purchase Agreement (PPA) is worth a look. A third party pays for, installs and maintains the system on your roof, and the OMC simply buys the electricity it uses, at an agreed rate below normal grid prices.

• No upfront cost: the funder owns the system and takes care of maintenance.
• Two agreements: usually a roof lease plus the PPA itself, so the funder has the right to keep the panels on the roof.
• Long terms: commercial solar PPAs in Ireland commonly run 10 to 15 years.
• End of term: typical options are to extend, buy the system or have it removed. Check this before signing.

Solar PPAs in Ireland are mostly offered to businesses today, and an apartment block needs to be big enough to interest a funder. The OMC’s legal advisers should review the lease and PPA, including what happens if the roof needs repairs. For smaller blocks, a grant-funded system the OMC owns outright is often better value over 25 years. We can price both options for you.
