A record 34,0888 households in Ireland have installed solar panels in 2025, according to data from the Sustainable Energy Authority of Ireland (SEAI).
This represents a 16% increase from the previous year, when more than 29,000 grant-assisted installations were awarded under the SEIA’s Solar PV Scheme in 2024.
Compared between 2023 and 2025, the increase was 49%, highlighting the continued interest in residential solar PV from Irish households.
Five counties – Clare, Kerry, Waterford, Mayo and Wexford – showed adoption levels of more than 1,000 households each, helped by the Solar PV Scheme that offers up to €1,800 (£1,560) for a solar installation.
“The pace of adoption we saw last year shows that Irish households and businesses are taking climate action seriously. With SEAI grants and falling costs, solar PV is becoming an increasingly viable financial decision and a no-brainer for those looking to reduce their energy bills. There’s a €1,800 grant available from the SEAI in 2026 for those who wish to install solar panels on their rooftops,” said Briain Kelly, editor at EnergyEfficiency.ie.
Kelly added that the upward trend is poised to continue in 2026, which will further support Ireland’s transition to a low-carbon economy.
The continued interest and growth of solar PV in Ireland is not exclusive to the residential sector. Utility-scale solar PV set a new yearly generation record by the end of July, and with five more months to increase the record. Between January and July 2025, utility-scale solar PV had supplied 753GWh of electricity to the Irish grid, surpassing 2024’s entire year, which was set at 659GWh.
