Get Solar QuotesSee Cost After GrantThe short answer: what solar panels cost in Ireland in 2026
There is no single price for solar panels in Ireland. Two homes on the same road can get quotes thousands of euro apart because of roof type, access, panel count, inverter, battery and electrical work. What you can get is a reliable range. These are the most useful published reference points we found, each checked on 25 October 2026:
€1,700–€2,500 per kWp
SEAI’s own guidance on its Solar Electricity Grant page says “the typical cost is €1,700 – €2,500 per kWp” for a home system, before the grant. This is the best neutral benchmark to measure quotes against.
€6,000–€9,000 after grant
An Irish Times special report (15 Oct 2026) put solar PV for an average Irish home at between €6,000 and €9,000 after the grant of up to €1,800 is deducted.
€8,000–€12,000 for 4kWp
MyHome.ie’s retrofit guide (2026, undated) says a 4kWp solar PV system in Ireland typically costs €8,000–€12,000 before grants.
Not every source agrees. Bord Gáis Energy (22 May 2026) quotes a much lower €3,500–€6,000 after grants and VAT savings, while Selectra (updated 12 Sept 2026) gives total installation costs of €5,000–€16,000 before grant. The spread is the point: the only price that counts is a written, itemised quote for your own roof. That is why we recommend comparing several quotes.
Solar panel cost by system size
System size is measured in kilowatt-peak (kWp). With today’s 430–485W panels, 1kWp is roughly two panels. The table shows two kinds of figure, clearly separated: arithmetic from SEAI’s €1,700–€2,500/kWp range, and published prices from named Irish sources. All are before grant and include VAT at 0% unless stated.
| System | SEAI range arithmetic (before grant) | Published Irish prices (before grant) |
|---|---|---|
| 2 kWp (about 4–5 panels) | €3,400–€5,000 | Small systems often cost more per kWp because scaffolding, labour and the inverter are largely fixed costs. Electric Ireland says its installations start from approximately €6,800 before the SEAI grant (no system size stated; checked 25 Oct 2026). |
| 3 kWp (about 7 panels) | €5,100–€7,500 | PureVolt example quote, 3.88kWp (8 panels), Midlands, May 2026: €7,600. |
| 4 kWp (about 9–10 panels) | €6,800–€10,000 | MyHome.ie: €8,000–€12,000. PureVolt example, 4.85kWp (10 panels), May 2026: €8,000. |
| 5–6 kWp (about 11–14 panels) | €8,500–€15,000 | PureVolt example, 5.82kWp (12 panels), May 2026: €8,400. Larger homes and heat pump/EV owners are the usual buyers. |
| Battery added at install | – | PureVolt: a 5.3kWh battery adds around €1,300–€1,400, including the hybrid inverter it needs (May 2026). Energia (18 Mar 2026): a 5kWh battery costs €1,700–€3,000. Selectra (12 Sept 2026): about €2,000–€3,500 for a 5kW-class battery and €4,500–€7,000 for 10kW-class. |
| Battery-only retrofit (existing panels) | – | No Irish source we found publishes a retrofit-specific price. Use the battery ranges above as a floor, then add any inverter change: an older string inverter usually means an AC-coupled battery with its own inverter, or replacing the inverter with a hybrid unit. The Irish Times (25 Sept 2026) said batteries “typically cost more than €4,000”; Bord Gáis gives €3,000–€7,000 by capacity. |
| Commercial (per kWp) | – | PureVolt publishes €1,300–€1,600 per kWp installed, ex VAT: around €39,000–€48,000 for 30kWp and €65,000–€80,000 for 50kWp (checked 25 Oct 2026). This is one installer’s list; larger arrays usually cost less per kWp. |
SEAI arithmetic = system kWp × €1,700 and × €2,500, rounded. It is not a quote. Installer example prices are for the specific houses described on their pages and will change. All sources checked 25 October 2026.
Cost after the SEAI grant
The SEAI Solar Electricity Grant (checked 26 Oct 2026) pays €700 per kWp up to 2kWp (€1,400 for 2kWp), plus €200 for every additional kWp up to 4kWp, with or without a battery, so the panel grant is capped at €1,800. There is a separate €600 grant for a 5kWh battery, making a maximum of €2,400. Panels above 4kWp get no extra grant.
Most SEAI-registered installers deduct the grant from your invoice, so the quote you compare is the net figure. Key rules: use an SEAI-registered company, wait for your Letter of Offer before any work starts, and arrange the post-works BER (ask whether its cost is included in your quote). Full eligibility is on our solar grants guide; lower-income households should also read about the Working Family Payment solar grant.
Ask your installer or SEAI to confirm the exact grant on your Letter of Offer.
| Per kWp, up to 2 kWp | €700 |
| 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 |
Worked examples: price after grant
Illustrative arithmetic only. These combine the published prices above with the grant figures. They are not quotes and not a prediction of what you will pay.
Example A: 3kWp, panels only
SEAI range: 3 × €1,700–€2,500 = €5,100–€7,500.
Less grant (€1,400 for the first 2kWp + €200): −€1,600.
Net: about €3,500–€5,900.
Example B: 4kWp, panels only
SEAI range: 4 × €1,700–€2,500 = €6,800–€10,000.
Less grant (panel maximum): −€1,800.
Net: about €5,000–€8,200.
Example C: 4.85kWp, panels only (published price)
PureVolt’s May 2026 example: €8,000.
Less grant: −€1,800.
Net: €6,200 (as shown on the installer’s page).
Example D: 4.85kWp plus 5.3kWh battery
€8,000 + battery €1,300–€1,400 = €9,300–€9,400.
Less grant (€1,800 panels + €600 battery): −€2,400.
Net: about €6,900–€7,000.
0% VAT on solar panels for homes
Since 1 May 2023, the zero rate of VAT applies to the supply and installation of solar panels on or adjacent to private dwellings, per Revenue’s VAT guidance on solar panels (document last reviewed May 2025; checked 25 Oct 2026). Recognised schools were added from 1 January 2024.
What qualifies
Panels supplied and installed by the same business, plus ancillary equipment installed with them. Revenue’s examples include wiring, controllers, combiner boxes and batteries.
What doesn’t
Panels bought on their own (supply only) are at the standard rate. Commercial, industrial and public buildings, shops, hotels, B&Bs, short-let holiday homes and farm buildings are excluded. A farmhouse that is a private dwelling still qualifies.
Check your quote
A home quote should show 0% VAT on the supply-and-install contract. Business quotes are usually given ex VAT; VAT-registered businesses may be able to reclaim it – ask your accountant.
What drives the price of a solar quote
Panels themselves are now a modest share of a home system. Most of the difference between quotes comes from the job around them. Ask every installer to itemise these:
Roof type and access
Tiled, slate, metal and flat roofs need different mounting. Flat roofs need ballasted or fixed frames angled to the sun. A two-storey house with a conservatory or limited side access takes more time.
Scaffolding
Safe working at height usually means scaffolding or edge protection, which is a largely fixed cost – one reason a 2kWp job costs more per kWp than a 5kWp job. Confirm whether it is included.
Inverter choice
A standard string inverter is cheapest. A hybrid inverter costs more but lets you add a battery now or later. Microinverters or optimisers help on shaded or split roofs but add cost per panel.
Battery
Usually the largest single extra. Capacity (kWh), usable depth of discharge, warranty and whether it can charge on a cheap night-rate tariff all affect price. See our battery advice.
Hot water diverter
A diverter sends surplus solar to your immersion instead of exporting it. SEAI calls this “a very low cost solution”. Worth asking about if you have a well-insulated cylinder.
Bird mesh
Pigeons nesting under panels are a common Irish complaint. Mesh around the array edge is an optional extra on many quotes. Ask whether it is included and priced separately.
Three-phase and grid limits
Most homes are single-phase. ESB Networks micro-generation (NC6) allows up to 25A (≈6kVA) single-phase or 16A per phase (≈11kVA) three-phase. Bigger systems go through mini-generation, which takes longer and can cost more.
Electrical upgrades
An old consumer unit, long cable runs to a garage or ground mount, or a new earth rod all add labour. A survey should flag these before you sign.
Panel brand and wattage
Higher-wattage or all-black panels cost more per panel but can mean fewer panels on a small roof. See our guide to the best solar panels in Ireland.
Payback: what affects your return
Published payback estimates for Irish homes fall in a narrow band: the Irish Times (Oct 2026) reports typically five to eight years, citing SEAI’s calculator, and Bord Gáis Energy (May 2026) says five to seven years for most households. Your own figure depends on:
Net cost
The price after grant and 0% VAT. A cheaper quote shortens payback only if the kit and workmanship are equal.
Your electricity price
The Irish Times report cites standard unit rates of between 36c and 45c per kWh. Every solar unit you use yourself avoids that rate.
Self-consumption
Units used in the home save much more than units exported. Daytime occupancy, a diverter, a battery, a heat pump or an EV all raise self-consumption.
Export payments
Under the Clean Export Guarantee your supplier pays for surplus units. The Irish Times cited a rate “currently around 19.5 cents” per kWh (Oct 2026); rates vary by supplier and change. See grants and tax.
Ask installers for a written generation estimate (kWh/year) and the self-consumption assumption behind any savings figure. Use your smart-meter data from ESB Networks if you have it.
How to compare solar quotes properly
Comparing totals alone is misleading. Line quotes up side by side using these checks – our compare solar quotes guide goes deeper.
Compare cost per kWp (total ÷ kWp) and confirm whether the price is before or after the SEAI grant.
Panel model and wattage, inverter model, battery model and usable kWh – not just brand names.
Scaffolding, bird mesh, diverter, consumer-unit work, monitoring app, NC6 notification to ESB Networks, BER and grant paperwork.
Panel product and performance warranties, inverter and battery warranties, and the installer’s own workmanship guarantee.
SEAI-registered solar PV company, Safe Electric registered electrician, and insurance. Ask for recent local installs you can see.

Solar panel cost FAQs
How much do solar panels cost in Ireland in 2026?
SEAI puts the typical cost at €1,700–€2,500 per kWp before grant. The Irish Times (Oct 2026) reported €6,000–€9,000 for an average home after the grant. Your own price depends on size, roof and extras – get itemised quotes.
What is the price of a single solar panel?
Panel-only prices are not a useful guide for a home system: the panels must be installed by the same business to get 0% VAT and by an SEAI-registered company to get the grant, and labour, inverter, scaffolding and electrical work make up much of the bill. Compare installed cost per kWp instead.
How much does a 4kWp solar system cost?
MyHome.ie quotes €8,000–€12,000 before grants; SEAI’s per-kWp range implies €6,800–€10,000. The panel grant is €1,800, or €2,400 with a battery.
Is there VAT on solar panels in Ireland?
For private homes, supply and installation of solar panels has been zero-rated since 1 May 2023, including ancillary equipment such as batteries installed with them. Business premises pay the standard rate.
Is a battery worth the extra cost?
It depends on how much solar you would otherwise export, your evening use and your tariff. A battery also qualifies for SEAI’s €600 battery grant. Read our battery advice before deciding.
Can I get a grant for adding a battery to existing panels?
SEAI’s page doesn’t clearly address battery-only retrofits, and SEAI supports solar PV only once per address. Ask SEAI or a registered installer to confirm before you buy.
What does commercial solar cost?
One Irish installer, PureVolt, publishes €1,300–€1,600 per kWp ex VAT for SME systems. Businesses use a separate SEAI non-domestic grant and may claim Accelerated Capital Allowances – see industries we service.
Why are quotes so different?
Scaffolding, roof type, inverter and battery choice, bird mesh, electrical upgrades and panel brand all vary. Compare equipment and inclusions line by line, not just the total. More answers on our FAQ page.
