Ireland Farm Solar PV Systems for Dairy and Poultry

Key Takeaways

• The TAMS 3 Solar Capital Investment Scheme (SCIS) provides significant financial support for farm solar PV.
• Eligible farms must be engaged in farming activity and meet a minimum of 20 Production Units.
• A grant aid rate of 60% is available, up to a ring-fenced investment ceiling of €90,000.
• Applications require a DAFM Solar PV Survey and are submitted online via your agfood account.

Powering Irish Dairy and Poultry Farms with Solar PV

Integrating solar PV systems into Irish dairy and poultry operations offers a sustainable approach to managing energy costs and reducing environmental impact. The Targeted Agricultural Modernisation Scheme 3 (TAMS 3) Solar Capital Investment Scheme (SCIS), administered by the Minister for Agriculture, Food and the Marine, supports these investments. This scheme commenced on 20 June 2026 and is open for applications.

Solar PV systems can align with the specific energy demands of modern farms. For dairy parlours, solar generation can synchronise with high loads from vacuum pumps during milking times, direct expansion bulk milk cooling, and water heating. In poultry sheds, solar can power variable speed fan ventilation and cooling systems, particularly during high ambient summer temperatures when solar generation is also at its peak.

The TAMS 3 Solar Capital Investment Scheme Framework

The TAMS 3 Solar Capital Investment Scheme (SCIS) is funded by the Irish Government and part-financed by the European Union. It aims to support farmers in adopting renewable energy technologies. The scheme offers a substantial grant aid rate to encourage investment in solar PV.

To be eligible for the SCIS, applicants must be engaged in farming activity. A minimum of 20 Production Units is required to qualify for the SCIS. General requirements for applicant eligibility also apply. The system must be sized to meet on-farm agricultural demand, based on an approved DAFM Solar PV Survey calculation. This survey considers electricity bills or a stock-based consumption model to ensure the system primarily serves on-farm needs. Commercial generation solely for export is not eligible for this scheme.

Grant Rates and Eligibility for Farm Solar PV

The TAMS 3 SCIS provides a clear framework for financial support and eligibility. The grant aid rate is set at 60% of eligible reference investment costs. This support is capped by a ring-fenced investment ceiling of €90,000 per holding, which is separate from other TAMS 3 general ceilings.

The eligibility criteria extend beyond minimum production units. For instance, extensions to existing farm structures are eligible for grant-aid, but conversions are not. It is also critical that any proposed new structure or extension does not include a roof over an existing agitation point or an internal agitation point, as this will render the application invalid.

The Application Process for Farm Solar Grants

Applying for the TAMS 3 SCIS grant involves several steps, primarily through the Department of Agriculture, Food and the Marine's online systems. Applications are submitted online through your agfood account. Access to the online application form is available to approved agricultural advisors and applicants directly through GCPS – the Department’s Generic Claims/Payment System. An Agent/Client User ID, Password, and PIN are required.

A crucial step is the submission of a DAFM Solar PV Survey. A copy of this survey must be uploaded at the time of application for TAMS 3 Grant Aid. This survey helps determine the appropriate system size for your farm's energy needs. Applicants can amend their application prior to submitting or withdraw a submitted application and resubmit before the closing date for receipt of applications for the particular tranche. Once an application has been submitted, no further amendments are possible.

When completing the application, you will need to enter a Site Identifier, which is marked on your Farmyard Layout Plan showing the position of the proposed fixed investment. You must also enter the Proposed Cost of Investment. If your farm is located on an island, ticking the "Island Rate" option will automatically increase the Reference Costs by 33%. Planning Permission is assessed at the Sub-Investment level.

What the published sources do not tell you

While the TAMS 3 SCIS provides a clear framework for grants, certain specific details are not explicitly covered in the published documentation. These include detailed specifications for eligible solar PV equipment, such as specific inverter types, battery storage compatibility, or mounting requirements. There is also no specific guidance on calculating kWp sizing based on electricity bills or stock numbers for dairy and poultry farms, beyond the requirement for a DAFM Solar PV Survey.

The documents do not detail on-farm self-consumption requirements or export limitations, nor do they specify rules or eligibility for battery storage under the scheme. Specific information regarding ammonia corrosion mitigation for mounting hardware and inverters in poultry sheds is not provided. Similarly, detailed guidelines on dairy parlour vacuum pump and milk cooling solar integration, or specific requirements for poultry shed ventilation synchronisation with solar, are not outlined. The exact process for the "Solar PV Survey" and what it entails in terms of methodology is also not fully detailed.
