    I called sunpower by E2 solar today to see about servicing my current owned sunpower system since only sunpower systems can be serviced by an authorized dealer to keep the current warranty and apparently there only seems to be only a handful in the state I figured they would be able and willing to stand by the product they sell and service sunpower and actually do what they are supposed to do. unfortunately they said I am out of they're service area and would not be the ones to help with any services I need. This is very disappointing that this company tahts sells and is supposed to service th

    I highly recommend E2 Solar. From sales to installation, the employees were responsive, respectful, and answered all my questions. Their customer service is impeccable!

    I have been a customer of E2 Solar since 2016 when they designed and installed a solar panel array on my roof. The system has met all my utility needs since it was installed, and never failed to provide enough power to heat and cool my home both reliably and economically. They have always been prompt in answering my questions. Recently, I needed their help in correcting some roof issues which arose due to recent storms. The crew they sent was truly outstanding. They were courageous, professional, and solved the problem for me. I recommend them to anyone considering solar energy.

    Company and personnel were wonderful and the total experiences were trouble free! Thank you!

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.

  • Years in business

    “Local, Reliable Service E2 Solar has over 80 years of combined experience and thousands…”

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

Elsewhere

  • It is also reviewed on ConsumerAffairs and Yelp. Worth reading before you sign anything: those are a different crowd, and the complaints that reach the Better Business Bureau rarely reach Google.
  • It posts on Facebook. A page that stopped posting years ago tells you something a listing will not.

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.
