Available Grants and Incentives

All of our solar panel systems are eligible for SEAI grants and VAT exemption which lowers your initial investment, delivers a faster return on investment, and enhanced affordability of advanced systems with battery storage.

SEAI Grants

Homeowners in Ireland can benefit from Sustainable Energy Authority of Ireland (SEAI) grants, which offer up to €1,800 for installing solar PV systems. This grant significantly reduces the upfront cost, making solar energy more accessible.

VAT Exemption

A recent government initiative has made solar panel installations VAT-free. This further reduces the overall cost, providing an additional financial incentive to switch to solar energy.

 Trustindex verifies that the original source of the review is Google. Finally made the decision to go ‘Solar Panels’ for my house in Cork. I contacted a number of Suppliers and met their representatives but I just wasn’t convinced. Fortunately for me one guy stood out - he was particularly friendly, relaxed, struck up an instant relationship with my German Shepherd, Rebel, over a cup of tea (!), could explain all the 'Solar jargon' in an uncomplicated way, appeared to have endless patience and didn't come across even remotely pushy. The 'deal maker' that locked me in was all of the above plus I felt that he really wanted me to have a successful www.AEI.ie Solar service and investment experience. Daniel Costello is an absolute credit to AEI Solar! I've recommended him and AEI to many neighbours and friends since my installation. I've been back and forth to Daniel over the past few months looking for clarity in the various packs/proposals, checking various installation dates etc. and he has been superb. 5 Stars for Daniel and www.aei.ie from this particularly happy customer.

 Trustindex verifies that the original source of the review is Google. It's been 12 months since AEI installed our solar and battery but I only recently bought an EV and at the same time I had development  a small invertor problem and logged a ticket for support. After a number of emails back and forth Trevor called me and explained in simple terms on how a system should be run based on my usage pattern, much more so than any email could explain. His advise was simple to understand, we agreed a plan and he implemented it. Top class.
