Ireland's business solar grant nearly doubles from today - 45% of eligible costs for nine months, up from about 23%
From 6 October 2026 SEAI's Non-Domestic Microgeneration Grant pays 45% of eligible solar PV costs for a nine-month window, up from about 23%. SEAI's estimate for an average installation: about €12,000 a year saved, for about 1,250 businesses. The grant pays toward the solar. There is no separate business battery grant in it.
Yesterday this desk said Ireland's business line was a large government savings claim with no table behind it. SEAI's own announcement has the table. Here it is.
From 6 October 2026, the Non-Domestic Microgeneration Grant - the Irish grant for solar panels on business, farm, public-body and non-profit buildings - rises from about 23% of installation cost to 45% of eligible costs, for nine months. SEAI describes it as a fixed value of support per unit of solar installed. Its own estimate for an average installation is about €12,000 a year in savings, for roughly 1,250 businesses.
The same package lifts business heat pump and solar thermal grants, under the Business Energy Upgrades Scheme, to 45% of eligible costs, at about €3,500 a year saved each on SEAI's numbers.
Workplace meaning: a roof that did not stack up at 23% is a different sum at 45%. Pinergy, a supplier, put out its own example on 1 October: a 100 kWp roof with €100,000 of qualifying costs goes from about €22,600 of support to up to €45,000. That is a vendor's example, not SEAI's, and not your site.
Battery line, kept straight. The grant pays toward the solar. SEAI's scheme code of practice allows a battery on the job and sets rules for it - compliance with I.S. 10101, a fire-resistant base where the floor is not one, and an AC-connected battery listed on the ESB Networks NC5 to NC8 connection form as extra generator output. There is no business battery grant in this package. The €600 battery grant on this desk yesterday is for homes.
Analogy: a half-price sale with a closing date on the door and a sign saying the till rules are still being printed.
The scheme has a track record: SEAI counts 3,160 installations and over €33 million paid since 2022, from more than 6,100 applications. SEAI also says demand on some of its programmes is up over 200% this year.
Good: A hard opening date (6 October), a hard rate (45%) and a hard window (nine months). Named savings estimate from the agency that pays the grant.
Bad: No battery money for business. The €12,000 is an average-install estimate, not an audit of your meter.
Ugly: SEAI says the measures open "subject to final implementation arrangements", with full terms and eligibility "in due course". Nine months is short once grid paperwork, approvals and installer queues are counted, and a 200% demand jump on some SEAI programmes suggests installer and approval queues may already be long.
