What reviewers said

  • 5★ · around August 2026 · the company replied

    I had a great experience working with OneGen Power. Fernando was knowledgeable, honest, and took the time to explain all of my options without any pressure. The entire process was straightforward, and I felt confident every step of the way. It’s hard to find companies that genuinely put customers first, but that’s exactly how OneGen Power operates. If you’re considering solar or battery backup, I highly recommend reaching out and seeing what they can do for your home.

    We had a great experience with OneGen Power! Our rep was friendly, knowledgeable, and took the time to answer all of our questions without ever making us feel pressured. The whole process was smooth, and we felt comfortable every step of the way. If you’re thinking about going solar, they’re definitely worth checking out!

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.
  • We found nothing on a website for this company that states a warranty, a licence or how long it has traded.
  • Google publishes no street address for this company, so we cannot say which town it is based in. Marysville 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.
