For a solar PV grant in Ireland, start by checking the SEAI website for the current Solar Electricity Grant rules and its list of registered contractors. You can contact several approved installers in your area for site assessments and written quotes, as the suitable system and likely grant support depend on your home and installation. In general, you should apply through SEAI and receive approval before work begins, but the exact process and grant level can change. SEAI or your chosen registered contractor can confirm whether your property and planned system meet the current requirements.
