The SEAI solar PV grant is calculated at €800 per kWp for the first 2 kWp, then €250 per kWp for the next 2 kWp, subject to a maximum grant of €2,100. For example, a 2 kWp system could qualify for up to €1,600, while a 4 kWp system could reach the €2,100 maximum. You must apply before installation and use an SEAI-registered contractor, with eligibility and the final approved amount depending on your home and project details. Check the latest rates and requirements on SEAI’s official website, as these can change.
