First, check the current SEAI solar PV grant rules and whether your home appears to meet the basic requirements. Next, get a quote from an SEAI-registered solar PV contractor and submit your application before any installation work begins. Wait for SEAI’s approval, then arrange the installation with the contractor and keep the required invoices, certificates and other paperwork. After completion, follow SEAI’s claim process; the final grant and eligibility are decided by SEAI based on your application and supporting documents.
