A guide, not a quote: the installer prices your own roof. 0% VAT on panels for homes.

What's included

  • The panels, the inverter and the mounting rails
  • Access to the roof on a normal house, scaffolding if it's needed
  • The ESB Networks paperwork before the panels go live
  • Testing, and the paperwork SEAI needs to pay your grant
  • 0% VAT, because it's a home

What pushes it up or down

  • Up: a high, steep or slate roof that needs more scaffolding
  • Up: panels on two sides of the roof, or a split array
  • Up: a long cable run to the fuse board, or a fuse board that needs work
  • Up: a battery, an EV charger or a hot water diverter
  • Down: one plain south-facing roof with easy access
  • Down: the full SEAI grant, offer in hand before any work starts

Questions we get asked

How much is the SEAI solar grant?

SEAI pays €700 per kWp for the first 2kWp of solar panels, so €1,400 for 2kWp, about 6 or 7 panels, and €200 for each extra kWp up to 4kWp, so €1,800 at 4kWp, the cap for panels. A battery of 5kWh or more adds a flat €600.

What's the most I can get?

€2,400: €1,800 for 4kWp or more of panels, plus €600 for a battery of 5kWh or more.

Who can get it?

Owners of homes built and occupied before 2025, with an MPRN. SEAI can't have supported solar PV at that address before, a BER assessor rates the home after the panels go in, and you must use an SEAI-registered solar company and have the grant offer before work starts.

Do I need a BER?

After the panels are fitted, an SEAI-registered BER assessor does a post-works BER. It's needed to claim the grant, and there's no set rating to reach. A battery-only grant, where the home has no panels, doesn't need one.

Can the panels go up before the grant is approved?

No. Works must not start before you get SEAI's grant offer. Sign with an installer, apply, wait for the offer, then the panels go up. Start first and you lose the grant.

What will panels cost after the grant?

SEAI puts the typical cost at €1,700 to €2,500 per kWp. So 2kWp is about €3,400 to €5,000 before the grant, and €2,000 to €3,600 after it; 4kWp with a battery is about €5,000 to €8,200 for the panels after the €1,800 panel grant, plus the battery less its €600. These are SEAI's typical rates times the size, not quotes.

How long does it take?

Allow two to three months from signing. The grant offer comes first and is valid for 8 months. The installer's application to ESB Networks takes at least 4 weeks (20 working days). SEAI asks you to allow up to 6 weeks for payment after the paperwork, longer if it inspects.

Is there much mess or disruption?

Very little. The panels go on from the outside, the inverter goes in the attic, a garage or a utility room, and the power is off for a short while when it's wired into the fuse board.

Who comes out to the house?

One SEAI-registered solar installer who covers your area. They ring you, look at the roof and the fuse board, and give you a written price. Nothing is booked until you say yes.

Is this SEAI?

No. solarpanelgrant.ie is not SEAI or a government body and does not award grants. We pass your request to one SEAI-registered solar installer who covers your area. You apply to SEAI yourself, or the installer helps you; SEAI decides and pays the grant.
