A roof leak led our roofers to ask the solar to check if the leak came from their installation so the roofers would not inadvertently void a solar warranty. I asked HI Power to let me know if the panels by the leak area were under warranty (some of our panels are old, not warrantied). They charged me over $600 to tell me no, not related to solar panels. $455 for initial inspection. Plus $175/hour for extra time. All done with no communication, just sending me invoices. Apparently, unasked, they took each panel off and reattached them. I still have a roof leak led, still don't know what is under warranty, and I am out over $600.

Rory has been a solid salesperson looking out for us and making sure we were on schedule. Their office always called to confirm install dates, changes and also double checked via email. Finally, Jordan Bush as the crew chief was very good in doing the initial inspection and letting me know the next steps that would be involved. Their crew was prompt and let me know when they would be at our home to start. Always good to have confidence in the company for such a big investment. Jordan did the final hookup and left us with a great feeling we had installed something valuable. I recommend Island Pacific Energy to all who are looking for a solid local company that stands apart from the others that don't return calls, don't communicate well, don't follow up and make promises that aren't fulfilled.

My expectation was low as I didn't even get a call or messages back from a few other solar companies, including the one who did our installation!

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.

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.

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!!!
