The SEAI Solar PV grant is calculated by system size, with support generally available at €800 per kWp for the first 2 kWp and €250 per kWp for the next 2 kWp, subject to the current maximum grant of €1,800. This means the amount is not simply a fixed payment and may depend on your eligible installation and the programme rules in force when you apply. Your application must meet SEAI requirements and use a registered contractor, so approval and the final amount are not guaranteed. Check the latest rates on the official SEAI website before signing work or requesting a quotation.
