SEAI’s Solar PV Grant may help eligible homeowners with the cost of installing solar panels, but the available support and conditions can change. Eligibility can depend on the property, when it was built, previous grants received and whether the work is completed by an SEAI-registered installer. You will generally need to apply before installation begins, and the installer can explain any BER or documentation requirements. Check the latest rules on the official SEAI website, as SEAI makes the final decision on eligibility and payment.
