  • "Horrible service"

    Reviewed Aug 12, 2022

    After getting multiple quotes, we chose NuWatt to install our solar panels and a battery in the fall of 2020--because of supply chain issues, NuWatt was one of only two companies we found that offered an optional battery. Their quote was competitive and the crew was professional and worked quickly once we got on the schedule, which took a little while.

    System became operational in January 2021. In June 2021, the battery (a Sonnen battery with a 10-year warranty) stopped working. NuWatt was initially responsive and their wonderful electrician who'd done the install came out a couple of times to try to fix the problem and replaced a part as advised by Sonnen. None of this worked.

    We chose NuWatt specifically because we needed a battery in order to have reliable backup power during outages. THE BATTERY HAS NOT BEEN OPERATIONAL IN OVER ONE YEAR. They sporadically reply to our emails and phone calls, always promising to follow up "in a couple of weeks" or "later this month," but have not followed through in many months. NO ONE HAS COME TO INSTALL THE REPLACEMENT PART THAT SONNEN SHIPPED TO OUR HOUSE IN DECEMBER 2021. They also told us we would have to pay out of pocket to have the battery removed or replaced. We cannot recommend them to others.

    NuWatt Energy installed our photovoltaic system late 2017. All appointments were kept as promised and the installation went without any hitches.
    My husband is an electrical engineer, and they were able to answer his technical questions and accommodate his requests. The installation went smoothly without a hitch. Since then, we have had a few technical questions that they have promptly answered. In sum, they are very professional.
    We highly recommend them.

  • "Excellent experience with NuWatt team"

    Reviewed Jul 18, 2022

    I rarely write reviews and am doing so because NuWatt Energy deserves to be commended and rated for their excellent work. From start to finish, and with no exception, the team at NuWatt has been knowledgeable, professional, pleasant, and easy to work with. We highly recommend them to our friends and family and to anyone looking for a trustworthy company.
