    Diamond Energy made going solar so easy! Their team was friendly, smart, and explained everything clearly. They set up a system just right for my home, and the installation was fast and neat. I really like using clean energy & my bills are way lower now—plus, I get credits for extra power! Their customer service is awesome too. I definitely recommend them!

    Outstanding Service from Jesse & Diamond Energy Group! Jesse and the team at Diamond Energy Group are simply the best! He helped me and several of my friends secure the best solar deals, making the entire process seamless and hassle-free. His expertise, transparency, and commitment to customer satisfaction are second to none. If you’re considering solar and want to save big, I highly recommend reaching out to Jesse at Diamond Energy Group. You won’t be disappointed!

    Very professional. Great company. They showed us the best savings so it was an easy decision. Throughout the entire process they had great communication and handled everything.

What the company says about itself

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

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.

What we don't know

  • 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. Commack 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.
