We recently worked with Kai to get solar system installed at our place. Right from the start, it…read morewas clear he knew his stuff. Kai gave us some great advice about what kind of setup we needed. When he first came over to check out the property, he took time figuring out the best spots for everything. We were really happy with the quality of their work and the equipment used. Everything looks neat and tidy. We first planned on doing the solar setup ourselves. But considering how tough it can be to get stuff shipped to the island and after seeing Kai's pricing - which included getting it all set up for us - we felt it was a good deal. They managed to get everything done in just one day, and by the time they left, we were switching on lights in our new place. Even though it's only been a day since they finished, I'd easily give Kai a perfect 10 for the work he did. We'd definitely suggest him to anyone thinking about going solar. Working with him was smooth and easy-going. Update: Its been about three weeks since the solar was installed, and we are still very satisfied with our setup. Mahalo Kai!

We have an electric car and a swimming pool pump, as well as the usual all-electric home needs. They took care of the permitting process. Their electrical installers could not have done a more clean and professional installation. The whole process was quick and painless. Our monthly power bill was nearly $600. Now we pay the basic connection fee to HELCO and not much more. I do need to time the charging of the car to the daytime when the solar panels produce the most power. My power bill this past month was $40. At a $500/month savings, this system will pay for itself in about another 3 years. Even when the HELCO grid goes down, we donʻt miss a beat.

The senior project manager, Jaymie, had to intervene, because I left voice mails of disappointment and regret. Jaymie was great with communication. But Oahu manager, Steph, is like Spencer. She's hard to get in touch with and doesn't return calls when you have a question. Installation team of Josh and Kekoa were great and quick. Josh took pics of my roof tile grout cracking and Kekoa said they can help me fix it while they were up there. This was on February 14th, Kekoa said he'll reach out to Josh to get it fixed. Jaymie reassured me with a couple of phone calls saying that she will reach out to Kekoa. Fast forward to today, March 27th, and NO ONE has reached out to me. Hence to 2 stars. It would've been higher if communication and promptness with Kekoa could've been better. I would be wary of using an "off island" company like ProVision. If I knew it would be like this, I would've used an "on island" company. I would've paid a couple thousand more to have better customer service.

In December 2024, after waiting 9 months for permits, the house was framed. The plumber quickly did his part. Scott and I walked the house, I told him what I needed, and on January 20, 2025, sent him the plans. Initially, he said he had them; then I heard nothing more. He did not respond to texts or phone calls, I even taped a written request to contact me. I finally found him at his business, he said he would send me an estimate I then heard nothing for 3 weeks. In many texts, I asked him just to tell me if he was too busy. Today, I went to his business at 6:30 am, and asked him if wanted to do it. He told me I could "get in line" but it would be a long, long time If he had just responded to my texts, I could have found a new electrician and not have my house sit u touched since January. This is causing me to lose thousands on prolonged rent; fortunately my landlord is kind and won't evict me
