Solar Panel Leasing vs Buying in Ireland: An Honest Comparison for 2026

Solar panel leasing and PPAs promise no upfront cost. But they rarely deliver the same financial return as buying. This guide gives Irish homeowners an honest comparison of leasing versus buying — with the numbers that matter.

Solar panel leasing in Ireland — and its close cousin, the Power Purchase Agreement (PPA) — has grown as a financing option for homeowners who can’t or don’t want to pay upfront for solar. The core promise: get solar panels on your roof for no money down, and immediately start saving on your electricity bill.

The catch: when you don’t own the system, you give up the SEAI grant, the MSS export income, the long-term asset value, and often a significant portion of the total financial return. This guide gives you the complete picture — with real numbers — so you can make an informed decision.

The Three Models Explained

Model 1: Outright Purchase (Ownership)

You pay for the system (typically €8,000–€13,000 after the SEAI grant), own it completely, and receive all the financial benefits: self-consumption savings, MSS export income, and any property value uplift.

Model 2: Solar Lease

You pay a fixed monthly lease payment (typically €50–€120/month) to use panels installed on your roof. The leasing company owns the panels. At the end of the lease term (typically 10–20 years), you may have an option to purchase. In Ireland, true panel leasing is relatively uncommon compared to PPAs.

Model 3: Power Purchase Agreement (PPA)

You sign a long-term contract (typically 10–20 years) with a solar developer who installs panels on your roof at no cost to you. You agree to buy the electricity generated at a fixed price (typically 8–18 c/kWh — below grid retail rates). The developer keeps the MSS export income and any other benefits. At contract end, you may have an option to buy the panels.

Head-to-Head Comparison: 20-Year Scenarios

For a 4 kWp system on an Irish home, comparing outright purchase vs PPA over 20 years:

Scenario A: Outright Purchase (After SEAI Grant)

Net investment: €8,200 (after €1,800 SEAI grant)
Year 1 self-consumption savings (45% at 30 c/kWh): €499
Year 1 MSS export income (55% at 20 c/kWh): €407
Year 1 total benefit: €906
Total 20-year benefit (3% annual electricity price increase): approximately €22,000
Net 20-year return: €13,800
IRR (Internal Rate of Return): approximately 9–11%

Scenario B: PPA (No Upfront Cost)

Upfront cost: €0
PPA electricity rate: 15 c/kWh (charged to you instead of the grid rate of 30 c/kWh)
Self-consumed electricity saving per kWh: 30 c (grid) – 15 c (PPA) = 15 c/kWh saved
Year 1 self-consumption saving: 3,700 kWh × 45% × 15 c = €250
Export income: Goes to developer — €0 to you
Year 1 total benefit: €250
Total 20-year benefit (electricity prices rise, PPA rate escalates by contract terms): approximately €5,500–€8,000

20-year net return comparison:

Outright purchase: +€13,800 net
PPA: +€5,500–€8,000 net (all going to savings, no capital at risk)

The financial difference is substantial. Outright ownership typically delivers 1.5–2× the lifetime financial return of a PPA.

What PPAs Offer That Ownership Doesn't

Despite the lower financial return, PPAs have genuine advantages in specific situations:

1. Zero capital required For households with no savings and difficulty accessing loans, a PPA is the only path to solar. No credit check for the panel installation itself (though the contract is legally binding).

2. No maintenance responsibility The developer is responsible for maintaining the system. If the inverter fails, they fix it. If a panel is damaged by a storm, they replace it. You have no maintenance cost or responsibility.

3. No technology risk If solar panel technology becomes dramatically cheaper in year 5, you’re not holding a depreciated asset. The developer takes the technology risk.

4. Simplicity One contract, one party responsible. No SEAI application, no ESB Networks notification, no supplier MSS registration.

The SEAI Grant Problem with PPAs

This is the most important financial point: you cannot claim the SEAI solar PV grant on a PPA system because you do not own the equipment. The grant is an owner’s incentive.

The SEAI grant of €1,800 is effectively extracted from you and retained by the developer as part of their economic model. On a system that would cost you €8,200 after grant if purchased, the developer is essentially capturing that €1,800 of public subsidy into their own return.

Property Sale Implications

This is where PPAs can cause real problems for Irish homeowners.

When you sell your home with a PPA solar system:

The PPA contract runs with the property — the new buyer inherits it
Some buyers will be reluctant to assume a long-term contractual obligation with a third party
Banks mortgage-valuing the property may not include the solar system value (since you don’t own it)
You may need to negotiate contract buyout with the PPA company to sell freely — often at a significant cost
Exit penalties in PPA contracts can be €3,000–€8,000 if you break the agreement early

For anyone who might sell within 10–15 years, a PPA creates real risk. Always read the exit clause carefully before signing.

Lease vs PPA: Key Difference

A solar lease is more like a car lease: you pay a fixed monthly fee regardless of how much electricity the panels generate. If a panel is underperforming or it’s a bad summer, you still pay the same monthly amount.

A PPA ties your payment to actual generation: you only pay for the electricity produced. A bad summer month costs you less.

For most homeowners, a PPA is preferable to a lease because your payment scales with production. But both are inferior to ownership in the long run.

When Leasing / PPA Makes Sense

Consider a PPA or lease if:

You genuinely cannot access finance and have no savings (credit history issues, recent bankruptcy)
You plan to move within 3–5 years and want short-term bill savings without capital commitment (but watch the exit clause)
You’re renting and the landlord is exploring solar — landlords may use PPAs to avoid upfront capital
Your property is unusual in ways that make grant and installer processes difficult (though this rarely applies)

For everyone else — particularly homeowners planning to stay long-term — the numbers clearly favour outright purchase with SEAI grant and SEAI green loan financing.

Checking a PPA Contract: What to Look For

Before signing any PPA in Ireland:

Exit clause: What does it cost to exit the contract early? Can you buy the panels at a fair price?
Annual rate escalation: Does the per-kWh rate increase each year? By how much? (3–5% annual increases are common and significantly affect 20-year economics)
Performance guarantees: What happens if the system underperforms?
Property sale: How does the contract transfer? Can the buyer exit?
Developer financial stability: Will the company still exist in year 15 to maintain the system?
Insurance: Who insures the panels against storm damage?

Get independent legal advice before signing a PPA contract of 15+ years — the obligations are significant.

Our Recommendation

For the vast majority of Irish homeowners in 2026, buy your solar system — whether cash, SEAI green loan, credit union loan, or bank green mortgage. The financial return is substantially better, you own the asset, and you avoid the property sale complications of long-term third-party contracts.

If you genuinely cannot access finance, a PPA is better than no solar at all. But treat it as a last resort, not a first choice.

Frequently Asked Questions

Is solar panel leasing available in Ireland?

Solar leasing in Ireland is less common than Power Purchase Agreements (PPAs), but both are available. In a lease, you pay a fixed monthly fee for using the panels. In a PPA, you pay per kWh of electricity generated. Both mean the company owns the panels, not you — which affects grant eligibility, MSS income, and property sales.

Can I claim the SEAI grant on a leased or PPA solar system?

No. The SEAI Solar PV grant is paid to the property owner for equipment they own. If a solar developer owns the panels under a PPA or lease, the grant is not available to you. This is a significant financial disadvantage of third-party ownership models.

What happens to a solar PPA when I sell my house in Ireland?

The PPA contract typically transfers to the new property owner. This can complicate sales as buyers may not want to inherit a long-term contractual obligation. Early exit from a PPA typically incurs penalties of €3,000–€8,000. Always check the exit clause before signing.

Does a PPA save money on electricity bills in Ireland?

Yes, but less than owning the system. A typical PPA charges 10–18 c/kWh for solar electricity (versus 28–33 c/kWh grid rate), saving 10–20 c/kWh on self-consumed solar. An owned system saves the full grid rate on self-consumed electricity and earns 18–21 c/kWh on exports — substantially more in total.

How long is a typical solar PPA contract in Ireland?

Most Irish solar PPAs run for 10–20 years. Longer terms give the developer more time to recoup their installation cost and make the economics work. Always read whether the rate escalates annually and what the buyout options are at the end of the term.
