    The only thing this company does professionally is scam people. Once you buy it’s bye bye to all communication, leaving you with a very expensive broken system. It doesn’t work. The promises of saving power are untrue. They become virtually uncontactable after you pay and install the solar system. On the off chance you do get someone out at your house, the employee turnover rate is so high it’s always a new person who is just as confused about what’s going on with this company as everyone else. The owner refuses to take any accountability but will gladly take your money. It’s been 4 months wit

    Haleakala Solar did an outstanding job installing our solar panel system and Tesla Powerwall batteries. From start to finish, their team was professional, knowledgeable, and efficient. The installation was completed with great attention to detail, and they took the time to answer all of our questions throughout the process. We're extremely happy with the quality of their work and the performance of our new system. If you're considering going solar, I highly recommend Haleakala Solar. They made the entire experience smooth and stress-free!

    Just had warranty replacement of a failed solar PV microinverter. The microinverter was under warranty, so the replacement part was free, but they charged for the service call. It was worth it to not have to go on my roof, remove a panel, swap out high voltage components, and put it back, then hook up the new microinverter to the monitoring system.

    They showed up on time, fixed the problem, and charged me exactly what they said they would. I've been a Haleakala Solar customer for about ten years, and I am happy enough to have sent many of my friends and clients to them.

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

    “process as well as explore potential financing options as there could be tax credits or…”

  • 24/7 availability

    “do arise in the future? Tesla offers 24/7 customer support along with…”

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

Elsewhere

  • Google also lists this company under roofing. A company that does both roofing and solar can handle the roof work a panel install often needs.
  • 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 LinkedIn, Instagram, YouTube and 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.

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.
