Solar panels for homes in Ireland: grants, batteries, planning and what to ask installers
A clear, up-to-date guide to rooftop solar for Irish homes – the SEAI solar and battery grants (capped at €2,400 in total), eligibility extended under Budget 2027, export payments and how to compare quotes from SEAI-registered installers.
Get Solar QuotesCheck Your Grant OptionsWhy solar suits Irish homes
Ireland is not known for sunshine, but solar PV panels generate electricity from daylight, not heat, and still produce power on bright overcast days. Output is highest from April to September and lowest in mid-winter, so a home system is best thought of as cutting your annual bill rather than covering every unit, every month.
Use your own power first
Every unit you generate and use in the house is a unit you don’t buy from your supplier. That makes self-consumption – running the washing machine, dishwasher, immersion or EV charger during the day – the main driver of savings.
Grants and 0% VAT
SEAI grants for panels and batteries (SEAI caps the total at €2,400), and the 0% VAT rate on supply and installation of solar panels for private homes, reduce the upfront cost.
Get paid for exports
Under the Clean Export Guarantee, your supplier pays you for surplus electricity you send to the grid, and a portion of that income is tax-free each year.
How Irish homes use electricity – and why it matters for solar
Most Irish households use the most electricity in the morning and from late afternoon into the evening, when cooking, lighting and TVs are on and people are home. Solar generation peaks around midday. The closer you can match your use to daytime generation, the better the return.
If someone is home during the day
Remote workers, retired couples and families with young children tend to use more electricity in daylight hours, so they get more value from panels alone. A battery still helps cover the evening peak.
If the house is empty during the day
Much of the midday output would otherwise be exported. A battery, a solar diverter for the immersion, or timers on appliances move that energy into your own use.
Night-rate and smart tariffs
Many homes are on day/night or smart time-of-use tariffs. Some batteries can charge from cheaper night-rate electricity in winter when solar output is low. Ask installers whether your inverter and battery support this and check your tariff with your supplier.
Heat pumps and EVs
A heat pump or electric car increases your electricity use, which can justify a larger system. Mention any planned heat pump, EV or charger when you enquire so installers can size the system for the next ten years, not just today.
Ask installers to estimate your self-consumption using your actual bills or smart meter data from the ESB Networks customer portal.
Typical system sizes for Irish homes
System size is measured in kilowatt-peak (kWp) – the panels’ rated output in ideal conditions. The right size depends on your roof space and direction, shading, annual electricity use and budget. Installers will assess your roof and usage, but these are the common starting points:
2–3 kWp
Suits smaller homes, apartments with suitable roofs, or lower electricity use. The first 2 kWp attracts SEAI’s highest grant rate (€700 per kWp), so a 2 kWp system gets €1,400 and a 3 kWp system €1,600.
4 kWp
A very common choice for an average family home. SEAI pays an extra €200 per kWp from 2 kWp up to 4 kWp, so a 4 kWp system gets the maximum €1,800 panel grant, with or without a battery. That is roughly 9–10 panels of 400–450 W each.
5–6 kWp and above
For larger homes, heat pump or EV owners. SEAI’s grant does not cover capacity above 4 kWp, so you pay full price for the extra panels. Most homes on a single-phase supply connect under ESB Networks’ micro-generation rules (up to about 6 kVA).
South-facing roofs give the most output, but east/west split arrays work well in Ireland and spread generation across the morning and evening. Ground-mounted panels in a garden are an option where the roof is unsuitable (see planning rules below).
SEAI solar PV grant for homes
The SEAI Solar Electricity Grant pays €700 per kWp up to 2 kWp – €1,400 for a 2 kWp system (around 6–7 panels) – and €200 for every additional kWp up to 4 kWp, with or without a battery, so the panel grant is capped at €1,800. SEAI also pays a separate €600 battery storage grant for a 5 kWh battery, bringing the maximum to €2,400. Your installer can confirm exactly what your chosen system qualifies for.
Who qualifies: homeowners (including private landlords), owner management companies and Approved Housing Bodies. The house must have been built and occupied before 2025 – Budget 2027 extended eligibility to newer homes (ESS News), so confirm the current rule on seai.ie. The home must also have an MPRN, and the MPRN must not have received solar PV funding before.
Key rules: use an SEAI-registered solar PV company; get your Letter of Offer before any work starts; the installer must notify ESB Networks before installation; complete works and paperwork within 8 months; and get a post-works BER from a registered BER assessor. SEAI pays the grant once documents and the BER are in – allow 4–6 weeks.
Figures checked on SEAI’s solar electricity grant page, 26 October 2026. The battery grant and extended eligibility were introduced alongside Budget 2027 (pv magazine). Always rely on SEAI’s own page for current rates.
| Up to 2 kWp | €700 per kWp |
| 2 kWp system | €1,400 |
| Each extra kWp to 4 kWp | €200 |
| 4 kWp system (panel maximum) | €1,800 |
| Battery storage grant (5 kWh) | €600 |
| Maximum with battery | €2,400 |
Enhanced grant (qualifying welfare payments)
| 2 kWp | €6,700 |
| 3 kWp | €7,550 |
| 4 kWp | €8,400 |
| 4 kWp + 5 kWh battery | €9,000 (max) |
Enhanced grant: Working Family Payment, Fuel Allowance and other payments
Homeowners who personally receive certain Department of Social Protection payments can get a much higher grant: €3,350 per kWp for the first 2 kWp and €850 per additional kWp up to 4 kWp (€8,400 maximum for panels), plus the €600 battery grant, for a total of up to €9,000. Qualifying payments reported include Working Family Payment, Fuel Allowance (National Fuel Scheme), One-Parent Family Payment, Domiciliary Care Allowance and certain Carer’s, Jobseeker’s and Disability Allowance cases. The payment must be received by the homeowner, not another household member.
Read our full guide to the Working Family Payment and Fuel Allowance solar grant. Some sources report that free-upgrade schemes for low-income or medically vulnerable households may include solar, but SEAI’s Warmer Homes Scheme pages do not currently list solar PV, so check directly with SEAI (01 808 2100) before relying on it.

Batteries: do you need one?
A battery stores surplus daytime solar so you can use it in the evening instead of exporting it. SEAI pays a €600 grant towards a 5 kWh battery, and a battery usually increases how much of your own solar you use.
Grant and VAT
SEAI lists a €600 battery storage grant, for a battery fitted by an SEAI-registered company. Revenue confirms batteries supplied and installed with panels under the same contract are zero-rated for VAT on private dwellings.
Adding one later
If you already have solar, you can apply separately for the battery grant as long as battery work has not started. Check your existing inverter is compatible, or whether a hybrid or AC-coupled battery inverter is needed.
What to ask
Usable capacity (kWh), warranty years and cycles, whether it can charge from night rate, backup capability during power cuts, and whether it is listed on SEAI’s technical requirements.
More detail in our solar battery storage advice guide.
Clean Export Guarantee and tax-free export income
When your panels produce more than the house is using and the battery is full, the surplus flows to the grid. Under the CRU’s Clean Export Guarantee (CEG), your electricity supplier pays you for every metered unit (kWh) you export, shown on your bill. You need a smart meter for metered export payments, and your installer must have submitted the NC6 form to ESB Networks. Each supplier sets its own export rate, so compare rates as well as import prices when choosing a supplier (see the CRU microgeneration guide).
Tax: income from exporting electricity generated at your sole or main residence is exempt from income tax up to €400 per year for 2024–2028, per Revenue’s guidance. Budget 2027 announced an increase to €600, being legislated in the Finance Bill (KPMG summary). Check Revenue for the start date before relying on the higher figure. Each person named on the electricity bill can claim the exemption.
| Single-phase micro-gen | Up to 25A (~6 kVA) |
| Three-phase micro-gen | Up to 16A/phase (~11 kVA) |
| Form for micro-gen | NC6 |
| Larger systems (to 50 kW) | NC7 |
| Connection charge (inform & fit) | None |

Planning permission for home solar panels
Since 7 October 2022, the Planning and Development (Exempted Development) (No. 3) Regulations 2022 (S.I. No. 493 of 2022) allow most houses to install rooftop solar without planning permission.
Rooftop on houses
No limit on panel area on the roof of a house, anywhere in the country, including in Solar Safeguarding Zones near airports. Conditions such as minimum setbacks from the roof edge still apply – your installer should design to them.
Ground-mounted
Free-standing panels in the garden are exempt up to a total of 25 sq m, generally under 2.5 m high, not in front of the house, and leaving at least 25 sq m of private open space.
When you need permission
Protected structures (where works would materially affect the character), some Architectural Conservation Area situations, and anything outside the exemption conditions. If in doubt, ask your local council for a Section 5 declaration.

FAQs
How much is the SEAI solar grant for homes?
SEAI pays €700 per kWp up to 2 kWp (€1,400 for 2 kWp) and €200 for every additional kWp up to 4 kWp, so panels get up to €1,800. There is also a €600 battery storage grant, for a maximum of €2,400. Homeowners on qualifying welfare payments can get up to €9,000.
My house was built in 2022. Can I get the grant?
Yes, as long as it was built and occupied before 2025, which is SEAI’s current rule after Budget 2027 extended eligibility to newer homes. Confirm the current rule on seai.ie before you apply.
Do I need a battery to get the panel grant?
No. SEAI pays €700 per kWp up to 2 kWp and €200 per kWp from 2 kWp to 4 kWp whether or not you fit a battery, up to €1,800. A battery adds a further €600, for a maximum of €2,400.
Do I need planning permission?
Usually not for rooftop panels on a house, under S.I. 493 of 2022. Protected structures and ground-mounted arrays over 25 sq m are the main exceptions.
Will I be paid for electricity I export?
Yes, under the Clean Export Guarantee your supplier pays for metered exports, with a smart meter. Up to €400 a year is tax-free (rising to €600 under Budget 2027, subject to legislation).
Can I start work before the grant is approved?
No. Starting works before your Letter of Offer means you lose the grant.
Is there VAT on solar panels for homes?
Supply and installation of solar panels, including batteries under the same contract, on private dwellings is zero-rated for VAT since 1 May 2023 (Revenue).
How long does installation take?
The physical installation is often a day or two. Allow time for the SEAI offer, ESB Networks notification (usually at least 4 weeks) and the post-works BER. See more FAQs.
