What's different about solar in Belmullet
- A south roof in Belmullet makes about 903 kWh a year for each kWp of panels, the most of the nine Mayo towns we checked. Ten panels (4.85kWp) make about 4,380 kWh: 568 in June and 104 in December.
- East and west roofs make about 717 kWh per kWp here, 79% of a south roof. A flat roof with panels at 10° makes 822.
- SEAI's home grant is for owners of homes built and occupied before 2025. On Census 2022, 95% of Belmullet's homes were built before 2011 and 5% since, all inside that rule.
- 50% of households in Belmullet own their home and 47% rent. The grant goes to the owner, so if you rent, it's the landlord who would apply.
- 19% of households live in a flat or apartment. Panels on a shared roof need the owners' management company to agree before an installer can price them.
- 9.9% of dwellings in Belmullet 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.
- 19% 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.
- Belmullet sits between Blacksod Bay and Broadhaven Bay. Near the sea, ask for panels tested for salt mist under IEC 61701 and stainless or aluminium fixings.
- Met Éireann's Belmullet station averages 3.6 hours of sunshine a day over 1991–2020, from 1.2 in December to 6.3 in May.
- The same station records 26.5 days of gales a year and a top gust of 94 knots, so ask what wind load the mounting is rated for.

Belmullet questions
How much do solar panels cost in Belmullet?
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 Belmullet?
About 903 kWh a year per kWp on a south roof, so 10 panels make about 4,380 kWh. East and west roofs make about 717 per kWp.
Can I get the SEAI grant for a house in Belmullet?
If you own it, it was built and lived in before 2025, and SEAI hasn't paid for panels at the address before. 95% of homes in Belmullet 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.
