What reviewers said

  • 5★ · around August 2026

    Sigway has been a trusted service provider close to 10 years now with over 3 upgrades to our off-grid requirements. William and his crew are spot on with commitment and responsiveness. They actually answer your phone calls and conduct business the way it should be done; with direct access and timeliness. We consider Sigway a key service provider for our special property and its mission purpose bringing unique experiences to kids of all ages. Mesa Grande Western RR.

    William and Tobias are terrific to work with. We always know they will do their best for us. It's really nice to know that they are honest, and that they stand by their work. They are also super reasonably priced. They never try to upsell you - they give advice that they would use themselves. We highly recommend choosing Sigway Energy for solar.

    Very happy with the service. William and his crew are very professional and caring.

Reviewer names are not published here. Negative reviews are shown first because they are the ones a listing hides, not because they are more representative.

What reviewers keep mentioning

  • electrical engineering 4
  • responsive 2
  • excellent work 2

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.

  • Licensed

    “You'll work one-on-one with a licensed engineer, ensuring seamless service…”

Elsewhere

  • 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.
  • 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.

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.
  • Google publishes no street address for this company, so we cannot say which town it is based in. La Puente 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.
