  What a great team RES has assembled. I don’t often write a review, but RES has changed that. From the start of the project to the end I have been impressed with the office staff to the installers and the rest. The finished product looks beautiful in the garage and now I’m living the dream with no electric bill in the future. Soon after installation was complete, our electrician did something to the system which didn’t allow the batteries to charge. I messaged the project manager and we spent the next 1/2 hr going over the system and solved the problem. It’s w great feeling knowing the company

  With a massive Kona low coming in, our Tesla Powerwall Storm Watch feature kicked in on its own and started charging our battery. The peace of mind just knowing we'll have a full battery if we lose electricity is priceless! Thank you Joe and the RES team!

  RES is great to work with. They are clear, knowledgeable and efficient. Very nice people too. They did an excellent job with our project. On time, on budget and completely transparent so you know what you are paying for. There are lots of solar companies out there and many are pretty sketchy. RES is legit. They will be my only company for any solar projects, repairs or upgrades.

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.

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

• Years in business

  “edge of the solar industry for over 30 years, leveraging our expertise to bring…”

Its website also mentions established, but not in a sentence we can quote cleanly.

• Google also lists this company under chimney, heating and cooling and insulation.
• It posts on Facebook. A page that stopped posting years ago tells you something a listing will not.

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.

• —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.
