Farming in Offaly — Why Solar Makes Sense
Offaly is predominantly a beef and mixed farming county. Beef and mixed farms typically have lower electricity demands than dairy or poultry, but still benefit from solar PV — particularly for water pumping, fencing systems, and general farm buildings. A smaller system (10–30 kWp) can cover most daytime electricity needs at a modest cost after the TAMS 3 grant.
