What's different about solar in Swinford
- A south roof in Swinford makes about 855 kWh a year for each kWp of panels, eighth of the nine Mayo towns we checked. Ten panels (4.85kWp) make about 4,150 kWh: 514 in June and 107 in December.
- East and west roofs make about 690 kWh per kWp here, 81% of a south roof. A flat roof with panels at 10° makes 783.
- SEAI's home grant is for owners of homes built and occupied before 2025. On Census 2022, 94% of Swinford's homes were built before 2011 and 6% since, all inside that rule.
- 64% of households in Swinford own their home and 34% rent. The grant goes to the owner, so if you rent, it's the landlord who would apply.
- 6.4% of dwellings in Swinford were empty holiday homes on census night. Panels on a house that's empty for much of the year export most of what they make, and exported power earns the export rate rather than saving the full unit price.
- 17% of households here heat mainly with coal, peat or wood, more than in most Mayo towns. A chimney on the south slope cuts the space and throws shade, so ask for the panel layout on a drawing.

Swinford questions
How much do solar panels cost in Swinford?
8 to 16 panels (3.88kWp to 7.76kWp) cost about €7,600 to €9,200 fitted, before the grant. Take off the €1,800 SEAI grant and that's €5,800 to €7,400. With a battery or a harder roof, most homes pay €6,000 to €9,000 after the grant.
How much power do panels make in Swinford?
About 855 kWh a year per kWp on a south roof, so 10 panels make about 4,150 kWh. East and west roofs make about 690 per kWp.
Can I get the SEAI grant for a house in Swinford?
If you own it, it was built and lived in before 2025, and SEAI hasn't paid for panels at the address before. 94% of homes in Swinford were built before 2011.
How much is the SEAI grant?
SEAI pays €700 per kWp for the first 2kWp of panels and €200 per extra kWp up to 4kWp, so up to €1,800 for the panels. A battery of 5kWh or more adds a flat €600, so the most a home gets is €2,400.
How long do panels take to pay back?
Typically five to eight years, depending on how much of the power you use yourself. Power you use saves you the full unit price, 36c to 45c per kWh on standard tariffs, while power you export earns around 19.5c per kWh. The Department of Energy estimates a 4kWp system with a battery could save as much as €900 a year.
