    Sorry to have to change my review. But after couple months to have my solar system, their customer service is not as good as before. I have my problem with my power wall while it tried to drain out itself even after the sun goes down. I tried to contact Sony and he said this is the calibration process so it should be like that. But I experienced the calibration process before, it should put my battery as standby mode without draining and it should show Calibration Processing on Tesla app. This problem happened after PGE came to my house so I would like him stop by and check to make sure everyt

    Finding an installer who cares about aesthetics as much as performance can be tough, but this team exceeded expectations. The solar panel placement looks incredibly neat and custom-tailored to our roof shape, and the Powerwall 3 integration was smooth from day one. Great communication, respect for our property, and immaculate attention to detail. 10/10!

    Great Solar Experience I’m very happy with my solar installation with TN. From start to finish, the process was smooth, professional, and easy. The team was knowledgeable, responsive, and explained everything clearly. They showed up on time, worked efficiently, and paid attention to every detail. What I appreciated most was the great customer service. They were always available when I had questions and made the whole experience stress-free. I’m very pleased with the installation and would definitely recommend TN to anyone considering solar.

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.

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.

  • Financing

    “why we offer competitive pricing and financing options to make solar energy affordable for…”

  • Warranty

    “25-year linear power output warranty, which guarantees that the module's…”

  • Years in business

    “Affordability Our team of experts has over 15 years of experience in the solar…”

  • Licensed

    “using your Level 2 EV charger. A licensed electrician can do the job. What are…”

Elsewhere

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

As Google published them when we last read the listing, not a live check. Ring before you drive anywhere.

Who Google shows alongside them

Google’s own “people also viewed” set, in Google’s order. It is Google’s comparison, not ours.

The ones without a link have no page here, either because Google does not categorise them as solar businesses or because we could not match the name to a listing with confidence.

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 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.
