How much are solar panels in Ireland? SEAI puts the typical cost at €1,700–€2,500 per kWp before grant (SEAI, checked 25 October 2026). For an average home, the Irish Times (15 October 2026) reported €6,000–€9,000 after the grant. That’s the short answer. This post goes a step further and shows what different system sizes could mean for your monthly bill. For a full breakdown by size, installer price examples and quote-comparison tips, read our main cost of solar panels in Ireland guide.
How much are solar panels in Ireland by system size?
System size is measured in kilowatt-peak (kWp). With today’s panels of roughly 430–485W, 1kWp is about two panels. Here are SEAI’s per-kWp range multiplied out, with the grant applied:
| System | Before grant (SEAI range) | SEAI grant | After grant |
|---|---|---|---|
| 2kWp (about 4–5 panels) | €3,400–€5,000 | €1,400 | €2,000–€3,600 |
| 3kWp (about 7 panels) | €5,100–€7,500 | €1,600 | €3,500–€5,900 |
| 4kWp (about 9–10 panels) | €6,800–€10,000 | €1,800 | €5,000–€8,200 |
| 4kWp + 5kWh battery | €8,500–€13,000 | €2,400 (max) | €6,100–€10,600 |
Published 4kWp prices vary: MyHome.ie says €8,000–€12,000 before grants, while Selectra gives a wider €5,000–€16,000 installed range. The only price that counts is a written quote for your roof.
The grant and VAT in one paragraph
SEAI’s Solar Electricity Grant pays €700 per kWp up to 2kWp (€1,400), plus €200 for every extra kWp up to 4kWp, so panels get at most €1,800. SEAI also pays €600 for a 5kWh battery, for a maximum of €2,400; confirm the current figures with SEAI. Supply and installation for a private home is at 0% VAT (Revenue). If you receive Fuel Allowance, Working Family Payment or another listed payment, SEAI’s higher grant goes up to €9,000 for panels and a battery (SEAI).
What could solar save each month?
These are illustrative examples, not promises. We’ve used:
- Generation of 913kWh per kWp per year, the national average from PVGIS data for a south-facing roof (PureVolt). East or west roofs and northern counties produce less.
- A unit price of 40c/kWh, inside the 36c–45c range the Irish Times cited.
- An export payment of 19.5c/kWh, the Clean Export Guarantee rate the Irish Times cited. Supplier rates vary.
- Our own assumption for how much solar you use at home (based on SEAI’s 80% figure for a 2kWp system, and lower without a battery for larger systems).
| System | Share used at home (assumed) | Bill saving / year | Export credit / year | Average per month |
|---|---|---|---|---|
| 2kWp | 80% | about €584 | about €71 | about €55 |
| 3kWp | 60% | about €657 | about €214 | about €73 |
| 4kWp | 50% | about €730 | about €356 | about €91 |
| 4kWp + battery | 75% | about €1,096 | about €178 | about €106 |
The monthly average hides a big seasonal swing. In June your bill may fall sharply and you may export a lot; in December the panels will cover very little. Plan your budget around the annual figure.
How to push your savings higher
- Run the dishwasher, washing machine and dryer in the middle of the day
- Fit a solar diverter so surplus heats your hot water instead of being exported
- Charge an EV during daylight at weekends
- Compare Clean Export Guarantee rates as well as import prices when you switch supplier
What changes the price of your quote
Roof type and access, scaffolding, inverter choice (a hybrid inverter lets you add a battery later), battery size, bird mesh and any consumer-unit upgrade all affect the total. Panel brand matters less than you might think: see our best solar panels in Ireland guide. Most homes on a single-phase supply connect under ESB Networks’ micro-generation rules, up to 25A (about 6kVA) (ESB Networks); bigger systems take longer and can cost more.
What’s included in a typical home solar price
A home solar quote should normally cover the full job, not just the panels. Check each quote lists:
- Panels: exact model, wattage and number
- Inverter: model, and whether it is a hybrid that can take a battery later
- Mounting system, cabling, isolators and any consumer-unit work
- Scaffolding or other safe access
- Notification to ESB Networks and SEAI grant paperwork
- The post-works BER, which SEAI requires before the grant is paid (ask whether its cost is in the quote)
- Warranties on panels, inverter, battery and workmanship
Anything missing is a likely extra later. Our compare solar quotes guide has a side-by-side checklist.
Is demand pushing prices up?
Demand is high. The Irish Times reported more than 31,000 SEAI solar PV grant applications in the first seven months of 2026, up 76% on the previous year. We haven’t found reliable published data showing how that has affected installed prices, so the best protection is getting more than one quote and comparing cost per kWp (total price ÷ system size).
Business and farm prices
Commercial and farm systems are priced and funded differently. Businesses usually get quotes ex VAT and use SEAI’s Non-Domestic Microgen Grant, which for new applications from 6 October 2026 to 6 July 2027 pays the lower of its grant table and 45% of the invoiced cost. Farmers can also look at TAMS. See our guide to solar panels for farms.

FAQs
How much is a 4kWp solar system in Ireland?
SEAI’s range implies €6,800–€10,000 before grant; MyHome.ie quotes €8,000–€12,000. After the €1,800 panel grant, that’s roughly €5,000–€8,200 on SEAI’s range.
How much do solar panels save per month in Ireland?
In our illustration, from about €55 a month for 2kWp to about €106 for 4kWp with a battery, averaged over the year. Your figure depends on your roof, usage and tariff.
Do I pay VAT on solar panels for my home?
No. Supply and installation of solar panels on a private home has been zero-rated since 1 May 2023, including a battery installed under the same contract, according to Revenue. Panels bought on their own, without installation, are at the standard rate.
Are solar panels cheaper with a battery?
No, a battery adds cost, but it also brings a €600 grant, taking the maximum SEAI grant to €2,400. It raises how much solar you use at home.
