Solar panel grants: up to €1,800

How the grant is calculated

The grant is tiered by system size, measured in kilowatt-peak (kWp):

Partial sizes are paid pro-rata — a 2.5kWp system, for example, receives €1,500. Systems above 4kWp get the full €1,800 but nothing extra beyond it, which is why the 4kWp, 10-panel system is Ireland's most popular: it maximises the grant while keeping the price sensible. Batteries and immersion diverters are not covered by the grant, though you can still add them to a grant-aided system.

Who qualifies

• Your home was built and occupied before 2021 (newer homes already meet NZEB standards).
• You are the property owner — owner-occupiers and landlords both qualify; tenants apply through their landlord.
• The property hasn't already received the solar PV grant (tracked by MPRN).
• You use an SEAI-registered installer and complete a post-works BER assessment.
• There is no means test and no minimum BER requirement to apply.

The 0% VAT bonus

Since May 2023, supply and installation of solar panels on private homes carries 0% VAT — a permanent change with no scheduled end date. Between the grant and the VAT rate, a typical 4kWp system that would once have cost well over €10,000 now lands at roughly €5,500–€7,500 net for most homes.

How to apply, step by step

1. Get quotes from SEAI-registered installers

   Compare at least two. Every installer in our network is on the SEAI register — start here.

2. Apply online at seai.ie

   You'll need your MPRN (top of your electricity bill), Eircode and your chosen installer's details. Approval is often issued within minutes.

3. Wait for your Letter of Offer

   Do not let any work start before this arrives — starting early permanently voids the grant. The offer is valid for 8 months.

4. Installation and ESB connection

   Your installer applies to ESB Networks (NC6) to connect your system to the grid, then completes the install — usually 1–2 days on site.

5. BER assessment and payment

   A registered assessor completes your post-works BER (€150–€300, paid by you), the Declaration of Works goes to SEAI, and the grant is paid — typically within 2–6 weeks.
