GrantWise Team: Eligibility can depend on the property, its age, whether solar PV has previously been funded, and the current SEAI scheme rules. You generally need to apply and receive approval before work begins, and use an SEAI-registered contractor for the installation. The final decision, including the grant amount, is made by SEAI based on your individual circumstances and the documents provided. Check the latest requirements on the official SEAI website or ask a registered contractor to confirm your position before committing to work.
