Which way to orientate panels to get optimum sunshine?


Farm solar, also known as agri-solar, is becoming a practical investment for Irish farmers who want to cut electricity bills, improve energy security, and make better use of available roof space. A well-designed farm solar panels in Ireland system can help power milking parkours, refrigeration, water pumps, lighting, ventilation, workshops, and farm offices.
For many farms, the strongest return comes from using solar electricity directly on site. Dairy, poultry, pig, tillage, and horticulture farms can be especially suitable because they often have high daytime electricity demand. Farmers considering commercial solar PV should begin with an electricity usage review, roof survey, and grant eligibility check.
One of the most important supports for Irish farmers is the TAMS 3 solar grant. The official TAMS 3 Solar Capital Investment Scheme supports solar investments on farms and is grant-aided at 60%, with a separate investment ceiling of €90,000.
Farmers should apply through their agfood account before starting work. It is also important to confirm system size, eligible costs, battery options, and documentation requirements before installation.
Planning rules for rooftop solar in Ireland have become more flexible. The official solar planning exemptions include agricultural buildings, although restrictions can still apply in Solar Safeguarding Zones, near protected structures, or in Architectural Conservation Areas.
For standard rooftop installations on farm sheds, planning may not be required, but larger ground-mounted systems or solar farm developments should be checked with the local authority before proceeding.
Most farm solar installations connect to the electricity network. Smaller systems may fall under microgeneration, while larger systems may use mini-generation or small-scale generation routes. CRU provides guidance on microgeneration in Ireland, including how exported electricity is paid, while ESB Networks provides guidance on mini-generation for systems mainly designed for self-consumption.
A professional agricultural solar installer should confirm the correct ESB Networks process, export limits, inverter requirements, and whether the farm’s supply is single-phase or three-phase.
Some farms may also look at the Non-Domestic Microgen Grant, which supports solar PV for businesses, farms, schools, community centres, and other non-domestic organisations.
For larger renewable projects, the Small-Scale Renewable Electricity Support Scheme may be relevant. SRESS gives farmers, businesses, schools, and community groups opportunities to lower energy costs or generate income from renewable electricity projects.
Dairy farms are particularly well suited to solar because electricity demand for milking, milk cooling, water heating, and wash-down often overlaps with daytime generation. The Teagasc and MTU Solar Energy Guide for Dairy Farmers covers solar PV design, planning, export, storage, TAMS 3, and SRESS considerations for dairy farms.
Farmers planning dairy farm solar panels should size the system around actual electricity use rather than roof space alone. Oversizing can reduce self-consumption and weaken the payback unless there is a strong export or storage strategy.
A solar battery storage system can help farms use more of their own solar electricity in the evening or during high-demand periods. Batteries are not always necessary, but they can be useful where demand continues after daylight hours.
Farmers should also consider future electricity needs such as robotic milking, heat pumps, EV charging for farms, electric machinery, or business expansion. Designing the solar PV system around long-term farm plans can improve return on investment.
A good farm solar installation starts with accurate design. Before choosing a system, review your electricity bills, available roof space, grant eligibility, planning position, and grid connection requirements.
