This is the second time we have gone to Hi Power Solar for our solar needs. Called Cindy and she…read moregave us excellent service. This time we wanted to add a battery to our PV. She came over to look at our system after researching what we had installed. (Hi Power Solar did not install our PV.) After confirming what she thought, she went over our options.

I chose this company based on their previous reviews, their family owned small-business model, and…read moretheir personable communication. When I first contacted them, they were very responsive, came out to our house multiple times to check it out, and even offered very reasonable and competitive pricing. Installation had a few hiccups because our house is old, weird, and probably very hard to work with, but we're very happy with our system. All the kinks that the team had to work through were fixed/solved in a very timely and quality manner. The only problem we had was getting updates between signing our agreement and installation. Understandably we waited pretty long to hear anything about installation due to the overload all solar companies were experiencing due to the federal tax credit being cut next year. Our drawings were back logged, not because of HI Power, but because of the approvals they were waiting for. But I had to reach out to multiple people at multiple times before someone could explain this to me. This really stressed us out for a bit that no one was getting back to us, but once they explained all the issues they were facing, everything worked out perfectly. I would still like to recommend this company compared to other bigger companies based off of my parent's and grandparent's experiences.

As luck would have it, my previous updated review of Ecosolar would not be my last…read more After converting my system from running off of Sunpower/Enphase's microinverters to Tesla's inverter from my new Powerwall Plus, I had some worry about what might happen with a single point of failure. Midway through summer, I found that out when my entire system went down when it failed. I reached out to Chris from Ecosolar right away and let him know that I was having a problem and he started troubleshooting immediately. After some investigation it was determined that the inverter had to be replaced and after waiting for Tesla to ship out the part, it was replaced in a timely manner. I was back up and running again, until December when my system started acting up again, this time seemingly having a problem with one of the batteries. I contacted Chris again and let him know that I was having a problem again, and although communication was rough with the end of the year approaching and federal tax credits expiring, I had a service appointment scheduled for the first week of January. On their site visit, it was determined that my new Powerwall Plus itself had gone bad. They were able to start the RMA process with Tesla and told me it would be replaced, possibly with a new Powerwall 3, because the Powerwall 2 was end-of-life and not in production anymore. That meant they would also have to replace my original Powerwall 2 as well with a new Powerwall 3 expansion pack. They hoped optimistically that I wouldn't have to wait too long for the replacement. Fast forward to April and it did take longer than expected for Tesla to send them the replacements but the good news was that Tesla did indeed replace both of my Powerwall 2 units with a new Powerwall 3 and expansion. This did require much more work on the part of Ecosolar to retrofit than just unplugging the old setup and swapping in the new one, for my particular case, and I appreciate the extra lengths they had to go through versus just having to swap out the old if Tesla had just sent a Powerwall Plus replacement instead. I had been down for a few months but the upside is that I have a brand new set of batteries now in 2026. I would say my solar journey has been rougher than I expected it to be. Parts have failed. Parts have been replaced under warranty. Yes, I've experienced periods of time where my PV system has been offline due to failures, and had to deal with big HECO bills until those failures were resolved. I've had two Powerwalls replaced under warranty in the last 7 years (technically 3 since they swapped my still working Powerwall 2 with a new expansion pack), and an inverter. I had problems with weird glitches with power that kept tripping the Powerwall into thinking that I was experiencing a power outage, that Ecosolar's technician helped to diagnose and find out was actually a problem with HECO's underground service feed into my home (which was another years long adventure with HECO altogether). Sunpower's PV control system got booted offline and needed to be reset remotely. Each time I've had a problem I've contacted Ecosolar and each time they've addressed it to the best of their ability. Yes sometimes it takes time to get things resolved, and it can be hard to be patient. Tesla seems to take awhile to get things sent here but they have always come through thus far too. My additional cost for all of their warranty work and service over all this time has been ZERO. Every single problem I've ever had has been addressed. It's great if you can invest in something like this and never have a problem, but I understand that things happen when you're dealing with new technology, and it sucks but sh*t happens. But when you do invest in something as expensive as solar, it's good to know that I've invested with a company that takes care of it's customers.

Just wanted to give an updated shout out to Chris Osaki and Michael French of Eco Solar…read more Specifically, what you can expect AFTER installation, even years later, in terms of system support. We had an issue arise late one evening multiple years after our system was installed. Instinctively, we reached out to Chris & Michael after contacting HECO and began getting calls/texts back from them around 7am the next morning. They connected us with industry professionals who got out to our house and resolved the issue the SAME day. We were worried we'd be without service/a fully working system possibly for multiple days, as you often hear about with other outfits. Not Eco Solar--they provide support and info well after purchase/installation. MAHALO!!!

Do not, I repeat, DO NOT waste your time with this company!…read more I reached out via email to inquire about an issue I had with our owned PV panels. The company who generated the photovoltaic solar energy system that was installed by another on island company on the home I purchased filed bankruptcy in Aug 2024! This left me with finding someone to come out and assess why my PV panels were not generating electricity and sending the energy to be used by my home or to be stored in our Tesla power walls. When I reached out I explained that the company who installed the system on our home told me via monitoring that I had micro-inverters that needed to be replaced. When PV Hawaii techs came to our home for a 'troubleshoot visit' they were unable to gain access to my PV panel inverter - which is from the company that filed bankruptcy! They pretty much told me the only thing they could do was gain assistance from the company who initially installed the PV solar energy system on our home, which mind you, already gave me a quote to restring our PV panels to a whole new inverter and then connect that to our Tesla power walls which would be thousands of dollars!! So, you're telling me that this company, PV Hawaii needs to reach out to a whole separate PV company to get this type of repair/work done!? They charged me $299 for pretty much coming out to my house and doing absolutely NOTHING. When I asked for a quote for them to restring my microinverters to a new inverter I was told via email that they were working on the quote. . . . I NEVER received a quote! Overall, if you own a business and find that you are unable to do specific type of work just let the customer know. Don't charge for services if those services cannot be done. And don't lie and say you're getting a quote together and then never provide a quote and ghost the customer! Stay far away from PV Hawaii and take your hard earned money to another business to meet your solar needs!!!!!

I have been a long-time customer of PV Hawaii, but my recent experience has been very…read moredisappointing. Earlier this year, I scheduled a repair for my system. After providing my credit card information as required for scheduling, a technician completed the work, and I was immediately charged over $1,700. However, a week after the completion of the work, I noticed the system was still not working properly. Despite sending three emails and making three phone calls to follow up, I have received no response. To my surprise, I instead received an automated email from PV HAWAII offering a quote to look into why my system is not working. I am writing this review with the hopes that the PV HAWAII owner will do the right thing and send a technician to correct the problem as soon as possible. I hope to resolve this promptly and see PV Hawaii stand by the quality of its work.

We had a great experience working with Julian and the Solartech team here on Oahu. From the start…read moreJulian didn't come across as a typical sales rep at all -- he felt more like a knowledgeable industry expert who offered thoughtful, objective opinions about different technologies and brands. Before meeting him, I spoke with two other solar companies. One rep came on extremely strong and the meeting felt very sales-driven and impersonal, which made it hard to trust the information being presented. The other rep seemed to still be in training and had to run nearly every question through a senior colleague. Working with Julian was a relief. He's clearly experienced and communicates in a smart, casual, and very approachable way. We also had a great experience with Jelly and Brandi from the Solartech administrative team--they were easy to work with and helped keep everything moving smoothly. Solartech's digital quote platform made comparing options and selecting our plan simple and easy to understand. We ultimately decided against Tesla batteries after learning about potential overheating issues, which can be a concern in a place as hot as Hawaii. We went with Enphase we're happy with our choice. The installation team was excellent as well. Nainoa, the lead electrician on our project, is a total pro--easy to talk to, great at problem-solving, and he helped us quickly figure out a battery placement challenge. He completed the electrical work in just a few hours. During the panel installation, the crew accidentally drilled through part of our roof which caused a small leak, but they responded immediately and repaired it right away. Everything was patched up and looks good as new. We really appreciated how quickly they addressed the situation. Post-purchase support has been just as strong. I had some questions about how our system was pulling power from the grid, and Julian took the time to explain everything. It turned out to be more of a settings preference than an issue. He followed up with helpful explainer videos and even called a week later to make sure everything made sense. Overall, we're very happy with the experience and appreciate the professionalism, transparency, and support from the whole Solartech team.
