For years, the “split incentive” has stalled renewable energy in the rental sector: landlords pay for the upgrade, but tenants get the lower bills. In 2026, the game has changed. With new BER requirements on the horizon and rising demand for “green leases,” commercial solar for tenants in Ireland has become a strategic win-win. Munster Solar helps landlords bridge this gap, turning solar installations into an asset that increases property value while significantly reducing a tenant’s operating expenses.
In the past, when we talked to commercial landlords about solar, we usually hit the same wall: “Why would I spend €30,000 on panels when my tenant is the one who benefits from the cheap electricity?”
It’s a fair question, and it’s one that’s frustrated the Irish property market for over a decade. This is what the industry calls the “split incentive.” Essentially, it’s a stalemate where the person with the power to improve the building (the landlord) has no financial reason to do so, and the person who wants the improvement (the tenant) doesn’t own the roof.
But as we navigate through 2026, that old logic is falling apart. Between new EU-driven energy regulations, the rise of dynamic electricity tariffs, and a rental market that is increasingly “green-conscious,” solar isn’t just a nice-to-have upgrade; it’s becoming a baseline requirement for a premium commercial lease. At Munster Solar, we’re seeing a massive shift in how landlords and tenants work together to get these systems on the roof.
If you own a commercial building, your biggest risks are vacancy and “brown discounting”, where a low Energy Performance Certificate (EPC) or BER rating makes your property harder to let and less valuable to sell.
The roadmap for Irish property is clear. Minimum BER standards are tightening, and by the end of this year, the pressure on “sub-standard” buildings (those with F or G ratings) is reaching a breaking point. Solar is the fastest, most effective way to jump a property from a C to a B rating. This doesn’t just “feel good”, it secures your legal right to let the building at a premium rate and prevents your asset from becoming “stranded.”
A building that generates its own power is worth more on the open market. In 2026, institutional investors and local buyers alike are looking for “future-proofed” assets. If two identical warehouses are for sale in an industrial estate in Limerick, and one has a 50kW solar array while the other relies entirely on the grid, the solar-equipped building will sell faster and for a higher price every single time.
Under the Budget 2026 updates, small landlords can now claim a tax deduction of up to €10,000 per property (for up to three properties) against Case V rental income. Crucially, this deduction can now be claimed in the same year the expenditure is incurred, rather than being deferred. This provides an immediate cash-flow benefit that helps offset the initial capital outlay.
For the business owner, the person actually paying the ESB bill, solar is a lifeline. In a world where Irish electricity prices remain among the highest in Europe, being able to lock in a “free” source of power for 20+ years is the ultimate hedge against inflation.
When a tenant moves into a “solar-ready” building, they aren’t just getting a shell; they’re getting a lower cost of doing business. For a retail shop or a small manufacturing unit, electricity can be one of the top three overheads. Solar changes that from a variable, rising cost into a fixed, manageable asset. This makes your property significantly more attractive than the drafty, G-rated unit down the road.
It sounds like marketing fluff, but in 2026, it’s a reality: employees want to work for sustainable companies. If a tenant is trying to attract high-level talent to their office or clinic, being able to point to a net-zero building or provide solar-powered EV charging for staff is a massive recruitment tool.
So, how do you actually make the math work for both sides? This is where the “Green Lease” comes in. A green lease is simply a standard commercial lease with added clauses that address energy use and sustainability. We’re seeing three main ways this happens in Munster:
Another factor changing the game in 2026 is the Clean Export Guarantee. Even if a building is vacant for a month between tenants, the solar panels are still working. The landlord can now receive payments for every unit of electricity spilled back into the grid. With rates from suppliers like Pinergy or SSE Airtricity hovering around 19c to 25c per kWh, the roof is literally earning money even when no one is inside.
We don’t just bolt panels to the roof and drive away. Commercial solar requires a different level of planning than residential. We look at:
The “split incentive” is a ghost of the past. Nowadays, a building without solar is a building that’s falling behind. Whether you’re a landlord looking to protect your asset or a tenant looking to protect your profit, the answer is on the roof.
The system is a permanent fixture of the building, meaning it belongs to the landlord. However, the benefits are immediately available to the next tenant, ensuring you never have a “dead” asset on your roof.
This is a common concern. When we design a commercial system, we often use “ballasted” or non-penetrative mounting systems where possible, making it easier to move panels if maintenance is required. We also provide a full maintenance schedule to the landlord to prevent issues before they start.
Yes, but it requires a “Lease of Rights” agreement. We often recommend the landlord takes the lead to ensure the installation meets the high standards required for building insurance and long-term property value.
While the residential grant is capped at €1,800, commercial grants through the Non-Domestic Solar PV scheme can be significantly higher, often covering up to €2,400 to €162,600 depending on the size of the installation and the business type. We handle all the paperwork to make sure you get every cent you’re entitled to.
Surprisingly little. Because we use high-quality, fanless inverters and durable Tier 1 panels, the systems are largely “set and forget.” We recommend a simple annual inspection, which we can handle as part of a service agreement. Check out our Solar Maintenance Blogpost for more info.
