Solar Panel Financing Ireland: 2026 Guide
Most Irish homeowners pay between €5,000 and €10,000 for solar panels in Ireland after the SEAI grant. You don't need to pay it all upfront: green loans from credit unions and banks, plus installer payment plans, let you spread the cost of solar panel financing over 3 to 10 years, often with positive cash flow from day one.

Quick Answer
Most Irish homeowners finance solar panels through a credit union green loan (from 4% APR) or pay upfront using the SEAI grant of up to €1,800. A typical €6,000 net cost financed over 5 years costs ~€110/month — less than the ~€90/month electricity savings, meaning positive cash flow from day one.

How Do You Pay for Solar Panels in Ireland?
A typical residential solar PV system costs €7,000–€12,000 before the SEAI grant. After the grant of up to €1,800 and with 0% VAT on residential installations, most homeowners pay €5,000–€10,000 out of pocket.
You have several ways to cover this cost. Paying cash gives you the lowest total price. If that is not an option, green loans from credit unions and banks offer competitive rates, and some installers provide their own payment plans. See our full cost breakdown for detailed pricing by system size. The right choice depends on your savings, monthly budget, and how quickly you want to own the system outright.
“Many credit unions across Ireland now offer green energy loans at preferential rates, recognising that solar panels reduce household running costs and increase property value.”

What Are the Solar Financing Options in Ireland?
There are five main ways to pay for solar panels in Ireland. Here is how they compare for a typical €6,200 solar panel loan (after the SEAI grant).
| Option | Typical APR | Term | Total Cost (on €6,200) | Best For |
|---|---|---|---|---|
| Cash Payment | 0% | N/A | €6,200 | Lowest total cost |
| Credit Union Green Loan | 4–8% | 3–7 years | €6,600–€7,400 | Local, accessible, flexible |
| Bank Green Personal Loan | 6–8% | 3–10 years | €6,800–€7,600 | Existing bank customers |
| Installer Payment Plan (Finance Ireland) | ~7.5% | 1–10 years | ~€7,600 | Convenience, point-of-sale |
| Standard Personal Loan | 7–12% | 3–5 years | €7,000–€8,200 | When green loans are unavailable |
Total costs are estimates based on €6,200 loan over 5 years. Actual rates depend on your lender, credit profile, and loan term. Always check the specific APR and total amount repayable before signing.
How Do Credit Union Solar Loans Work in Ireland?
Irish credit unions offer solar panel loans at 4% to 8% APR with terms of 3 to 7 years and loan amounts from €5,000 to €25,000. Many credit unions have dedicated "green" or "solar" loan products at reduced rates. They are often the most accessible option because decisions are made locally and they tend to be more flexible than banks.
Seven credit unions also participate in the government-backed SBCI Home Energy Upgrade Loan Scheme with rates from 2.99%, though this is only available when solar is part of a broader home energy retrofit (not standalone solar PV).
Advantages
- ✓ Competitive rates, often 4–7% APR
- ✓ No early repayment penalties with most credit unions
- ✓ Local decision-making and personal service
- ✓ Loan protection insurance included (at no extra cost)
- ✓ Flexible on credit history compared to banks
Things to check
- • You typically need to be a member (some let you join and apply)
- • Rates vary significantly between credit unions
- • Some require a savings history before lending
- • Maximum loan amounts vary by credit union
- • Check if the green rate applies specifically to solar
Example: Credit Union Solar Loan
Loan amount: €6,200 | APR: 5.5% | Term: 5 years | Monthly repayment: ~€118 | Total repayable: ~€7,100 | Interest cost: ~€900.
Rates and terms are illustrative. Contact your local credit union for their current green loan rates.
Which Irish Banks Offer Green Loans for Solar Panels?
AIB, Bank of Ireland, PTSB, and An Post all offer green personal loans for solar panel installations in Ireland at 6–8% APR, typically 1–2% below their standard personal loan rates.
These banks also participate in the government-backed SBCI Home Energy Upgrade Loan Scheme at ~3% APR, but that scheme requires solar to be part of a broader energy retrofit (insulation, heat pump, etc.) and cannot fund standalone solar PV. For solar-only installations, use the green personal loan products below.
| Bank | Product | APR (Solar PV) | Loan Range | Max Term |
|---|---|---|---|---|
| AIB | Green Personal Loan | From 6.4% | €3,000–€60,000 | 10 years |
| Bank of Ireland | Green Home Improvement Loan | From 6.5% | €5,000–€65,000 | 5 years |
| PTSB | Green Home Improvement Loan | From 6.5% | €5,000–€65,000 | 5 years |
| An Post | Green Personal Loan | From 6.9% | €2,000–€75,000 | 7 years |
Rates as of early 2026. Check each bank's website for current rates. Your BER (Building Energy Rating) certificate or SEAI grant approval letter may be required as proof of the energy upgrade.
Tips for bank green loans
- ✓ Apply with your existing bank first for potentially faster approval
- ✓ Have your SEAI grant approval letter ready as proof of the energy upgrade
- ✓ Compare the total amount repayable, not just the APR
- ✓ Ask about early repayment fees before signing
- ✓ Check the CCPC loan comparison tool at ccpc.ie for side-by-side rate comparisons
Does Financing Change the Payback Period?
Yes, but only by 1–3 years. A cash purchase pays back in 5–7 years, while a financed system pays back in 7–10 years depending on your interest rate. Monthly electricity savings of €100–€125 often match or exceed loan repayments, giving you positive cash flow from day one.
Worked Example: Financing a 4.4 kWp System
| System cost (before grant) | €8,000 |
| SEAI grant | −€1,800 |
| Amount to finance | €6,200 |
| Loan APR | 6% |
| Loan term | 5 years |
| Monthly repayment | €120 |
| Total repaid (including interest) | €7,200 |
| Total interest cost | €1,000 |
Monthly Loan Repayment
Monthly Solar Savings
Net Monthly Cost
Annual solar savings of €1,200–€1,500 mean your monthly savings (€100–€125) nearly match or exceed the loan repayment (€120). After the 5-year loan ends, the system generates free electricity for another 20+ years.
Even with €1,000 in interest, the total cost of ownership with financing (€7,200) is still far less than the €26,000+ in electricity savings over the system's 25-year lifetime.

Get Multiple Quotes First
Get at least 3 quotes from SEAI-registered installers before arranging finance. Knowing the exact cost helps you borrow only what you need. Prices vary 15–25% between installers.
Apply for the SEAI Grant First
Submit your SEAI grant application and receive your Letter of Offer before signing any finance agreement. The grant approval also serves as proof for bank green loan applications.
Compare APRs Widely
Check your local credit union, your existing bank, and at least one other lender. Use the CCPC comparison tool at ccpc.ie. A 2% difference in APR saves €300–€500 in interest.
Check Early Repayment Penalties
Most credit unions allow early repayment without penalty. Banks may charge a fee. If you might pay off the loan early (using savings or the SEAI grant refund), choose a lender with no early repayment charge.
Ensure the Installer is SEAI-Registered
Using a non-registered installer means you lose the €1,800 grant and may void your green loan eligibility. Always verify your installer is on SEAI's registered list before signing anything.
Factor in Export Income
Under the Clean Export Guarantee, you can sell surplus electricity back to the grid at 15–32c/kWh. The first €400/year is tax-free (extended to 2028). This export income improves your cash flow and shortens the payback period, even with financing costs.
Frequently Asked Questions About Solar Financing
Can I get a loan for solar panels in Ireland?
Yes. Most credit unions and all major Irish banks offer personal loans that can be used for solar panel installation. Many now offer dedicated green loans at reduced interest rates specifically for energy upgrades including solar PV systems.
What is the best way to finance solar panels in Ireland?
Credit union green loans are often the best option for most homeowners. They typically offer rates of 4 to 7% APR, no early repayment penalties, and local decision-making. If you have savings, paying cash gives the lowest total cost. Always compare at least three lenders before committing.
Do credit unions offer solar loans?
Yes. Many Irish credit unions now offer dedicated green or solar energy loans at reduced rates. Typical APR is 4 to 7% with terms of 3 to 7 years. Loan protection insurance is usually included at no extra cost. Contact your local credit union for their current rates, as they vary between branches.
Is there 0% finance for solar panels in Ireland?
No. There is no widely available 0% finance scheme for solar panels in Ireland. Some installers may occasionally run promotional offers, but these are rare and should be checked carefully for hidden fees or higher system prices. The closest equivalent is paying cash after receiving the SEAI grant, which effectively reduces your outlay by up to €1,800.
Can I get solar panels with no upfront cost?
No. There is no government-backed zero-upfront-cost scheme for most homeowners. However, financing with a green loan means your monthly repayments can be offset by monthly electricity savings, resulting in near-zero net cost from the start. The only fully free option is for medically vulnerable customers who depend on electrically powered medical equipment at home.
How much do solar panels cost after the SEAI grant?
After the SEAI grant of up to €1,800 and with 0% VAT, most homeowners pay €5,000 to €10,000 for a solar PV system in 2026. A typical 10-panel (4.4 kWp) system costs €5,500 to €7,500 net. The exact price depends on system size, equipment brand, and installer.
Is financing solar panels worth it?
Yes, in most cases. Even with loan interest, the total cost of a financed solar system is typically recovered within 6 to 8 years through electricity savings and export income. After the loan is paid off, you get 20+ years of near-free electricity. The key is to secure the lowest APR you can and keep the loan term to 5 years or less.
Can I claim tax relief on solar panel financing?
No. Homeowners cannot claim tax relief on solar panel loan interest. However, the first \u20ac400 per year of solar export income is tax-free (extended to end of 2028). Businesses can claim 100% Accelerated Capital Allowances on solar investments in Year 1, which can include financed equipment.
