• 5★ · around February 2026

  Éirí Group is a highly capable and experienced renewable energy developer with a strong focus on solar, energy storage, and broader clean energy infrastructure. With well over 10 years of combined experience, Éirí Group conveys professionalism and a customer-centric approach that aligns well with the needs of organizations seeking renewable energy deployment. The management team is excellent and a pleasure to work with. I highly recommend them as a resource for renewable energy infrastructure investment and the like.

  My wife and I decided to go with Corey O’Brien after a really long time trying to find the right person. Corey helped out so much thought out the whole way, he answered all our questions and made us feel super comfortable with our decision. Absolutely a pleasure working with him. He’s very knowledgeable and very kind. The whole process was flawless and fast. Highly recommend Corey.

  I used Corey and Eiri for my solar project and I couldn’t be happier with the experience. There was constant communication and I always felt informed. The whole process went really smooth from day 1 to installation day. Really happy overall!

Topics Google derives from the review text, with how often each appears. A frequent topic is not a good one: “price” turns up in praise and in complaints alike.

Taken from its own website. We have not checked any of it, and a sentence on a website is not evidence.

Its website also mentions free estimate, but not in a sentence we can quote cleanly.

• It posts on LinkedIn. A page that stopped posting years ago tells you something a listing will not.

Ordered by how much we can tell you about each, which is not an order of quality. We do not know which of these is better and would not say if we did.

• —The date above is the newest review we hold, which is not necessarily the newest that exists — we hold a large share of Google's reviews, not all of them.
• —Google publishes no street address for this company, so we cannot say which town it is based in. Lynn is the area its listing was returned for, not an address we hold.
• —We do not verify licences, insurance or bonding. Nothing here has been checked against a state licensing board.
• —We cannot tell you what an installation costs, and we hold nothing about the equipment they fit.
