Farm Solar FAQ — Laois
Is my farm roof in Laois suitable for solar panels?
Most farm buildings in Laois are well-suited for solar — large roof areas, south or east/west facing, and minimal shading. Asbestos roofs must be replaced before installation (which can also be covered under TAMS III). Your installer will conduct a structural survey.
Should I apply for TAMS III or the NDMG?
Do I need planning permission for farm solar?
Rooftop solar on agricultural buildings is generally exempt from planning permission in Ireland. Ground-mounted systems over 50m² on agricultural land typically require planning permission. Check with your local planning authority for site-specific guidance.
Can farm solar work with three-phase electricity?
Yes. Most farm solar installations connect to three-phase supplies, which is standard on Irish farms. Three-phase inverters distribute solar generation evenly across all phases. Your installer will specify the correct inverter configuration.
What is the payback period for farm solar in Laois?
Can I sell surplus farm solar electricity to the grid?
Yes. Under the Clean Export Guarantee (CEG), you can export surplus electricity at 15–25c/kWh. However, farm solar systems are sized for self-consumption, so maximising daytime usage (milking, cooling, drying) gives better returns than exporting.
Will solar panels affect my Bord Bia audit?
Positively. Solar PV contributes to the carbon footprint reduction section of Bord Bia’s sustainability audits. This is increasingly important as processors and retailers set Scope 3 emission targets across their supply chains.
Commercial solar in Laois can reduce business electricity bills by 30–50%. The SEAI Non-Domestic Microgen Grant (NDMG) covers up to €2,400, and the full cost qualifies for Accelerated Capital Allowance (ACA) tax relief in year one. A 50kWp office or warehouse system generates 44,400+ kWh/yr. Laois receives 1,278+ sunshine hours annually, ranking #10 of 26 counties for solar potential.
Why Go Commercial Solar in Laois?
30–50% Bill Reduction
Businesses with daytime electricity demand see the biggest savings from solar. A 50kWp system in Laois generates approximately 44,400 kWh/yr, typically covering 30–50% of a mid-size commercial premises’ electricity use.
NDMG Grant: Up to €2,400
The SEAI Non-Domestic Microgen Grant covers up to 2,400 kWh of installed solar PV capacity for businesses, community organisations, and public buildings. Applied for through SEAI before installation.
ACA Tax Write-Off
Solar PV qualifies for Accelerated Capital Allowance — 100% of the cost written off against corporation tax in year one. This effectively reduces net cost by your marginal tax rate (12.5–25%).
Clean Export Guarantee
Sell surplus electricity back to the grid at 15–25c/kWh through the Clean Export Guarantee. Weekend and holiday generation that exceeds on-site demand earns export income.
ESG & Sustainability
Visible rooftop solar demonstrates environmental commitment to customers, employees, and stakeholders. Measurable CO₂ reduction for ESG reporting and sustainability certifications.
25+ Year Lifespan
Commercial solar systems last 25–30 years with minimal maintenance. In Laois, a typical business system pays for itself in 4–6 years after tax relief, leaving 20+ years of near-free electricity.
Business Solar Grants & Incentives
Businesses in Laois can access the SEAI Non-Domestic Microgen Grant (NDMG) and Accelerated Capital Allowance (ACA) tax relief. Both can be combined for maximum savings.
| Grant / Incentive | Rate | Details |
|---|---|---|
| NDMG — up to 6kWp | €2,400 (max) | Applied via SEAI |
| ACA Tax Relief | 100% year-one write-off | 12.5–25% effective saving |
| Clean Export Guarantee | 15–25c/kWh exported | Ongoing revenue |

Commercial Solar FAQ — Laois
How much can a business save with solar in Laois?
Savings depend on system size and daytime electricity usage. A 50kWp system in Laois generates approximately 44,400 kWh/yr. At current commercial rates (25–35c/kWh), that’s €11,000–€15,000/yr in avoided electricity costs, before export income.
What is the NDMG and how do I apply?
The Non-Domestic Microgen Grant (NDMG) from SEAI provides up to €2,400 for solar PV on non-domestic buildings. Apply online at seai.ie before starting work. You need a registered installer and a valid BER/DEC for the building.
How does the Accelerated Capital Allowance work?
ACA allows businesses to write off 100% of the cost of qualifying solar PV against corporation tax in year one, rather than over 8 years. At the 12.5% rate, a €60,000 system saves €7,500 in tax in year one. The equipment must be on SEAI’s Triple E register.
Do I need planning permission for commercial solar?
Rooftop solar on commercial/industrial buildings is generally exempt from planning permission. Systems on protected structures or in architectural conservation areas may need permission. Ground-mounted commercial systems typically require planning permission.
What is the payback period for commercial solar in Laois?
After NDMG and ACA tax relief, a commercial solar system in Laois typically pays for itself in 3–5 years. Without incentives, payback is 5–7 years. Laois generates approximately 888 kWh per kWp installed per year.
Can I combine the NDMG with ACA tax relief?
Yes. The NDMG grant and ACA tax write-off can be combined. The ACA is calculated on the net cost after the NDMG deduction. This combination significantly reduces the effective cost of commercial solar.
What size solar system does my business need?
System size depends on your electricity consumption and available roof space. A rule of thumb: 1kWp of solar needs ~5m² of roof space and generates 850–950 kWh/yr in Ireland. Your installer will analyse your electricity bills and roof to recommend the optimal size.

Solar Panel Guide for Laois
Laois benefits from midlands flat terrain
Laois is predominantly flat to gently rolling lowland, with the exception of the Slieve Bloom Mountains along its western border with Offaly. This flat terrain means most properties have unobstructed sky exposure with minimal shading from hills or elevated land. The open bogland areas around Portarlington and Mountmellick provide particularly good conditions, and the county's central location means solar irradiance is close to the national average despite being inland.
Portlaoise's growth as a commuter town boosts solar demand
Portlaoise has grown rapidly as a Dublin commuter town since the M7 motorway opened, with large housing estates built in the 2000s and 2010s. These modern estates in Portlaoise, Mountrath, and Portarlington have standard concrete tile roofs and predictable south-facing rear elevations, making them straightforward for solar installation. Many residents commute to Dublin, leaving homes unoccupied during peak solar hours, which makes battery storage a practical addition to maximise self-consumption.
Slieve Bloom Mountains and terrain variation
The Slieve Bloom Mountains along the Laois-Offaly border rise to 527m, the only significant elevated ground in the county. Properties on the flat lowlands away from the mountains, around Portlaoise, Mountrath, and Portarlington, enjoy wide open skies with no horizon shading. Homes closer to the Slieve Blooms, around Clonaslee and Rosenallis, may lose some low-angle winter sun behind the hills, but this has negligible impact on annual generation since winter output is modest regardless.
Data centre development and grid improvements
Laois has seen interest from data centre developers due to its central location and proximity to high-voltage grid infrastructure around Portlaoise. While large-scale data centre projects have been controversial, the associated grid investment by ESB Networks has improved electrical infrastructure across the county. This benefits solar homeowners through faster smart meter rollout and more reliable grid connections for exporting surplus electricity under the Clean Export Guarantee scheme.
