How Much Can You Earn Renting Land for a Solar Farm

A letter arrives, or a man in a quarter-zip knocks on the door. He represents a solar developer, likes the look of your fields, and would like to talk about a lease. Every landowner asks the same question: what is it worth?


Nobody can tell you from the road. Two farms five kilometres apart can be offered rents differing by a factor of two, and the reason rarely has anything to do with soil. It has to do with a substation. We advise developers and investors on Irish solar, so what follows shows how an offer is built.


Key takeaways


• Teagasc puts typical Irish solar land rents at EUR 2,200 to EUR 3,500 per hectare per year, noting EUR 2,200 to EUR 3,000 is now more common, roughly EUR 890 to EUR 1,415 per acre.

• Grid connection is the biggest determinant of value. A site beside a 33 kV substation with spare capacity beats better land with no connection.

• Almost every deal starts with an option agreement, not a lease. Leases then run 25 years or more, usually indexed.

• Solar lease income does not qualify for farming tax reliefs. Teagasc states it is fully taxed with no deductible expenses.

• Decommissioning security, access rights and construction damage matter as much as the headline rent.


How much does a solar farm pay per acre in Ireland?


Teagasc puts typical solar land rents at EUR 2,200 to EUR 3,500 per hectare per year, and says EUR 2,200 to EUR 3,000 is more common as developers become more opportunistic. At 2.47 acres per hectare, that is roughly EUR 890 to EUR 1,415 per acre. Treat these as indicative benchmarks, not an entitlement.


That range records what has been agreed. It is not a tariff. Your offer reflects one project: its grid connection cost, planning risk, scale and route to market. Teagasc names location, sunlight, scale and connection costs as the key factors. Be sceptical of any page quoting a precise per-acre figure.


What affects the rent a developer will offer?


Factor

Impact on rent

Why

Distance to a substation with available capacity

Very high

Often the largest capex line. Every extra kilometre of cable erodes rent.

Capacity available at the connection node

Very high

No spare grid capacity means no project at any rent. Teagasc notes it is limited.

Voltage of the nearby network

High

Teagasc calls 33 kV ideal, 10 kV unsuitable, 110 kV often too large to connect to.

Site size and contiguity

High

Scale spreads fixed costs across more megawatts.

Need to cross third-party land

High

Wayleaves over neighbours add cost, delay and risk.

Planning risk

Medium to high

Nearby housing or designated landscapes depress what a developer commits.

Topography, ground conditions and flood risk

Medium

South facing slopes yield most. Poor bearing capacity means costlier piling.

Competition for the site

Medium

Two developers chasing one node gives you leverage.

Soil quality and agricultural class

Low

Solar does not care how good your grass is.

 

That last row surprises people. Good land is worth no more to a developer, arguably less, because planners and objectors scrutinise high quality farmland harder.


What makes land attractive to a solar developer?


Grid, grid and grid. Everything else is a tiebreaker.

Ireland's connection process runs through the Enduring Connection Policy framework, now ECP-GSS, set by the Commission for Regulation of Utilities in decision paper CRU/2024101. Applications go into batches with hard deadlines: the September 2026 batch required a pre-application notification by 30 June 2026.


ESB Networks, as the distribution system operator, handles applications with a total Maximum Export Capacity below 40 MW. At or above 40 MW, they go first to EirGrid for a transmission connection. Note the difference between Maximum Export Capacity, what a generator may push onto the network, and Maximum Import Capacity, or MIC, which governs what a site draws. MEC sizes the project, and your rent.


Charges are substantial: a project in the 20 MW to 100 MW band faces an ESB Networks generation application fee of EUR 61,332 excluding VAT before a panel is bought, from the same pot as your rent. The mechanics of securing a grid connection in Ireland require a landowner's attention.


How much land does a solar farm need?


Teagasc's rule of thumb is that 1 MW of installed capacity requires roughly two hectares, about five acres. Development has shifted towards schemes of 40 MW and above, so many new sites need at least 80 hectares, close to 200 acres.


That is array area, not usable area. Fencing can leave narrow, uneconomic strips around boundaries, and Teagasc warns landowners to clarify the total area rented. Inverter stations, substation compounds and tracks all take ground.


Irish yields are modest: around 850 to 1,050 kWh per kWp per year on PVGIS-based estimates, implying a capacity factor near 10 to 12 per cent. That conversion is our arithmetic, not a published statistic. Capacity is quoted in both MW and MWp, the latter measured at standard test conditions.


What is an option agreement and how does it differ from a lease?


An option gives the developer an exclusive right, for a defined period, to take a lease on pre-agreed terms. It does not oblige them to build. It does oblige you to sit still while they pursue planning, grid, surveys and a route to market.


 

Option agreement

Lease

What it grants

Exclusive right to take a lease

Right to occupy and operate

Typical duration

Several years, extendable against planning and grid milestones

25 years or more, often with extension rights

Your land use

Continues largely as normal, subject to survey access

Ceases over the demised area

Payment

Annual option fee, usually modest

Annual rent, indexed

Who is committed

You are bound. The developer generally is not

Both parties

Main risk to you

Land tied up for years with no guaranteed project

Counterparty quality over decades

 

That asymmetry is why the option deserves your solicitor's closest attention. Lease terms are usually fixed at option stage and annexed to the option document, so by the time the developer exercises, your negotiating position is gone. Teagasc's advice is blunt and correct: avoid exclusivity until full heads of terms are agreed.


How long is a solar farm lease?


Expect 25 years or more. Teagasc states a developer exercising its option will lease for 25 years or more, often 30 or more once inflation-linked reviews are included. Extension options at the developer's election can take exposure towards 40 years. Add the option period and construction, and four decades can pass between signature and reinstatement. That outlasts most succession plans.


How are option fees and lease rents structured and indexed?


Three structures dominate, often combined.


Fixed rent per acre or hectare, indexed. The most common and predictable. A set amount per unit area, reviewed against the Consumer Price Index, sometimes with a collar, meaning a floor and cap on annual uplift. Watch the collar: a 2 per cent cap in a 5 per cent inflation year erodes real value fast.


Rent per MW installed. Ties income to capacity built rather than area taken. Good if the layout densifies, less so if capacity is cut after planning.


Revenue share. Teagasc notes some developers offer a payment linked to site turnover. That gives upside if prices run hot, but carries merchant risk and needs audit rights.


Most landowners are better served by a solid indexed base with a modest share on top than a thin base and a large share they cannot verify.


Where does the money to pay your rent come from?


Two routes fund it. In RESS 5, the Department of Climate, Energy and the Environment reported 22 successful projects totalling 1,072.22 MW, of which 853.38 MW was solar, at a weighted average bid of EUR 98.81 per MWh. The alternative is a corporate power purchase agreement with a large electricity user, and Irish policy targets corporate PPAs covering 15 per cent of demand by 2030.


Both matter to you, because how RESS auctions are structured and priced and the tenor of a corporate PPA in the Irish market determine bankability. A project that cannot bank revenue cannot pay rent.


Who decides the planning application?


Commercial ground-mounted solar farms are generally determined by the local authority first, with appeal to An Coimisiún Pleanála, successor to An Bord Pleanála. This holds at scale: a 100 MW scheme in County Cork was refused by Cork County Council and granted on appeal.


Strategic Infrastructure Development, or SID, is a separate direct route to An Coimisiún Pleanála reserved for classes of development listed in legislation. Associated grid infrastructure can fall within it even where the generating station does not. If a developer calls their scheme a SID application, ask for the statutory basis.

Planning risk is the main reason options lapse, so test any promised timeline against the stages a renewable project passes through.


What happens to the land at the end of the lease?


The lease should require full decommissioning: panels, mounts, cabling, inverters, transformers, fencing, tracks and foundations removed, ground returned to agricultural condition.


The question is who pays if the operating company no longer exists in 2060. Teagasc advises ensuring provision is made for decommissioning and reinstatement, for example, a clean-up or security bond, or an insurance policy. Options include cash in escrow, a bank guarantee, a parent company guarantee, or a fund built from rent. A decommissioning bond sized in today's euros and never indexed is worthless in forty years.


Specify the standard too. "Reasonable condition" will be interpreted by someone who is not you. Foundation removal depth, track treatment, drainage and soil decompaction should be written down.


What are the tax implications for the landowner?


This is the general shape of the issue, not tax advice, and the position changes with each Finance Act. Take advice from a qualified tax adviser before you sign.

Teagasc's guidance sets out the core points. Income from solar farm leases does not qualify for traditional farming tax relief, and all lease and option income is fully taxed with no opportunity to offset expenses. That differs from the long-term agricultural leasing exemptions farmers may know.


The capital reliefs matter most. Teagasc notes land under solar panels does not qualify for agricultural relief unless less than 50 per cent of the farm area is covered, and that leasing under 50 per cent lets the farm retain working farm status. On capital gains tax, Teagasc states farmers over 55 who have owned and farmed the land for 10 years can transfer land with panels to a child without a CGT charge, subject to the same 50 per cent limit.


That line recurs, and it is the key planning point for anyone intending to pass the farm on. A lease crossing it can cost more in capital gains tax than the rent earns. Our commercial advisory and transaction support team works alongside landowners' tax advisers, not in place of them.


How does solar land rent compare to agricultural income?


Teagasc's preliminary National Farm Survey 2025 results put average dairy farm income at EUR 2,215 per hectare, on an average farm size of 69 hectares. Drystock systems earn a fraction of that. Across all systems, average family farm income was just over EUR 53,800 in 2025.


Set a solar rent of EUR 2,200 to EUR 3,000 per hectare against those figures and the picture is clear. For cattle and sheep enterprises, solar rent is transformative, and it arrives without weather, input cost, or output price risk. For a well-run dairy platform, it is closer. Two adjustments matter: farm income rewards your labour and capital too, and solar rent is taxed with no deductions.


What should you negotiate beyond the headline rent?


• Full cost indemnity. Teagasc advises ensuring the developer covers all legal, professional, planning and grid application costs whether or not the project completes.

• Battery storage. If storage is added, negotiate a separate payment. Batteries take up modest area and generate substantial revenue.

• Exact demised area, including fenced-off strips rendered unusable.

• Construction protocol. Timing, access routes, drainage and soil protection, clean up and fault correction. Teagasc notes some landowners were left with significant damage.

• Assignment control. Sites are frequently sold on, so have a say in who becomes your counterparty.

• Indemnity insurance during both option and lease periods, and milestone break rights so a stalled option falls away.

• Rent commencement. On lease grant, construction start, or energisation? The difference can be two years of income.


What are the risks for the landowner?


Dead time. The most common outcome of an option is nothing. Your land is encumbered for years, alternatives such as developing a project on different commercial terms are foreclosed, and you receive a modest fee.


Counterparty change. Teagasc identifies three developer types: site finders who obtain planning and grid then sell on, backed developers who build and may sell, and funded developers who operate long term. Ask which you face, and for references.


Tax leakage from crossing relief thresholds without advice. Inflation erosion from capped indexation. Abandonment by an operator that fails with no bond. Community relations, since the developer runs the planning application but you still live there.


None is a reason not to proceed. They are reasons to proceed with advice. For an independent read on whether a project is credible and the terms are market, talk to our team.


Frequently asked questions


How much does a solar farm pay per acre in Ireland?


Teagasc puts typical rents at EUR 2,200 to EUR 3,500 per hectare per year, noting EUR 2,200 to EUR 3,000 is more common. That is roughly EUR 890 to EUR 1,415 per acre. Offers depend heavily on grid connection cost, scale and planning risk.


How much land does a solar farm need?


Teagasc's guidance is that 1 MW of installed capacity requires about two hectares, roughly five acres. With development shifting towards schemes of 40 MW and above, many projects need at least 80 hectares. Fencing, inverter compounds and tracks reduce the usable balance further.


What is a solar option agreement?


An option gives a developer exclusive rights, for a defined period, to take a lease on pre agreed terms while it pursues planning permission, a grid connection and a route to market. You are bound; the developer generally is not. A modest annual fee is paid.


How long does a solar farm lease last in Ireland?


Expect 25 years or more. Teagasc states leases run 25 years or more, often 30 years or more with indexation. Extension options at the developer's election can push exposure towards 35 or 40 years, before adding the option period and construction phase.


Is solar lease income taxed differently from farm income?


Yes. Teagasc states solar lease and option income does not qualify for traditional farming tax relief and is fully taxed with no opportunity to offset expenses. Long-term agricultural leasing exemptions do not apply. Take professional tax advice before signing anything.


Will a solar lease affect agricultural relief?


It can. Teagasc notes land under solar panels does not qualify for agricultural relief unless panels cover less than 50 per cent of the farm area. That threshold also governs working farm status and certain CGT treatment on transfer to a child.


Why does grid connection matter more than land quality?


Because connection cost is often the largest capital item and network capacity is limited. Teagasc identifies 33 kV lines and substations as ideal, 10 kV as unsuitable, and 110 kV as often too large. A site with no viable connection has no project.


Who decides planning permission for a solar farm?


Generally the local authority first, with appeal to An Coimisiún Pleanála. Schemes as large as 100 MW have gone this route, including a Cork project refused by the council then granted on appeal. Associated grid infrastructure can follow a different consenting path.


What happens to the land when the lease ends?


The lease should require removal of panels, structures, cabling, foundations, fencing and tracks, with ground reinstated to agricultural use. Teagasc advises securing this with a clean-up bond or insurance policy. Ensure the bond is indexed, or it will not cover future costs.


Can I still claim BISS on land with solar panels?


Generally yes, subject to conditions. Teagasc notes parcels with panels are usually eligible provided agricultural activity such as sheep grazing continues, with panels treated as ineligible features. A proportional reduction applies, and parcels where ineligible features exceed 70 per cent are ineligible.
