“The pace of adoption we saw last year shows that Irish households and businesses are taking climate action seriously”, according to solar PV supplier Brian Kelly, of energyefficiency.ie.

“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 bill” he said.

“There’s a €1,800 grant available from the SEAI in 2026 for those who wish to install solar panels on their rooftops” he explained.

Households, communities, farmers, and businesses are all eligible for a range of SEAI solar PV grants, separate from the TAMS solar capital investment scheme.
