    I recently had a Tesla Wall Charger installed in my home and the process from beginning to end was very impressive. Communication was clear and prompt and any question I had was answered with confidence. The technicians who performed the install were great, the office representatives were awesome, and the charger works as expected. I would highly recommend Twinpeak Solar!

    After some pushy experiences with other solar companies, working with this team was a refreshing change. They were informative, honest, and took the time to present several options that fit both my needs and budget. They also worked with my aesthetic preferences and were transparent about production expectations. Honestly they felt like people who genuinely cared about finding the right solution rather than making a sale. Overall, it was a reassuring and positive experience, definitely recommend while shopping around❤️

  • It is also reviewed on the Better Business Bureau. Worth reading before you sign anything: those are a different crowd, and the complaints that reach the Better Business Bureau rarely reach Google.

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. Fairfield 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.
