This sales guy for Holu Hou was supposedly canvassing the area. 2nd day he came to our home. No soliciting sign and all. I tell him we have a dog and we are not interested. He keeps telling us he's not selling anything. Meanwhile my dog is barking like crazy. I literally had to tell him 3 times not interested. We have him on cameras and the neighbors do too, twice+. Drop off literature or be brief. Don't argue with us. Illiterate to disregard.

On Friday, March 13, 2026 my solar system was not working due to heavy rain and wind from the Kona storm the whole island chain was experiencing. So I called the company on the next day and spoke Jan Michael who was a team member for after hour customer service and he returned my call in about 20 minutes after I left a message. He explained to me about my system being off-line due to the sun being nonexistent and it seems my batteries were dead. Jan Michael was great with explaining my system to me and he was very professional and had great customer service. Later that day I received a call fr

I have been very happy with Holu Hou since they installed my solar system over four years ago. They are great communicators, knowledgeable, respectful, and very responsive, arriving and addressing issues within an hour. They even brought a back up battery late at night so I could sleep with my CPAP when a replacement part wasn't immediately available.

This review has been almost a year in the making. If you are thinking of starting a large scale Solar/PV project. I would recommend Holu Hou Energy. I did my research and contacted Holu Hou Energy & Kumu Kit. One contacted me in 3 days and the other contacted me in 3 months. Because of the scale of this project, I will break down my review into section. Initial Contact/ Project Sales In December 2022, I contacted Holu Hou Energy, and in three days, Sale Representative Cynthia contacted me, and we set up a meeting. She was very informative and made every aspect of the project clear. The financi

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.

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

Elsewhere

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.
It posts on Instagram, LinkedIn, 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.

Something wrong here? Tell us and a person will read it.
