Calculate your SEAI solar grant (up to €1,800) and payback period
This solar grant calculator uses only publicly published rates, bands, and rules from official Irish Government sources. It is NOT financial, tax, legal, or regulated advice. Results are approximate and for general guidance only. Your individual situation may vary. We accept no responsibility or liability for any reliance placed on these results. Always confirm with the official body (Revenue, RTB, SEAI, etc.) or a qualified professional.
Net cost of a 4 kWp system after the SEAI grant
€4,200
€6,000 installed, less a €1,800 SEAI grant. It pays for itself in about 7.0 years.
Grant rates: €700/kWp for the first 2 kWp and €200/kWp from 2 to 4 kWp, capped at €1,800. Savings assume current electricity prices and typical Irish generation for a south-facing roof; a shaded or north-facing roof will generate less. Work must be done by an SEAI-registered installer, and the grant is claimed after installation.
