I was left with no service provider. I called a couple of companies and they either couldn't provide service or the information given was really no help. I called Independent Energy and Sean-Daniel listened to the issue I was facing and provided excellent care. There were a lot of hoops to clear but Sean-Daniel guided me through the whole thing. Then to top it off just as the Tesla battery was finally ready for replacement, my inverter stopped working. Through our communication, I simply asked if that was also something they could help me with also. I simply had to provide some information and they took care of the rest. I was kind of left on my own with the previous company, but Sean-Daniel and Independent Energy really guided me through the replacement process and took care of me even though they were not the original installers. If you ever get into a situation similar to mine or looking to get any kind of solar service, I highly recommend Independent Energy of Hawaii1

Most recently my PV solar system had an alert that 1 of 2 inverters went down. I previously tried…read moreanother contractor about 1.5yrs ago with the same problem and the inverter was replaced. However, the other contractor had to send their tech out to troubleshoot before determining the problem, then once determined or confirmed it was an inverter issue, it took another 3 weeks to have it shipped and schedule a tech to come back in install. This process took about a month. You can imagine what my HECO bill was for being out of solar operation!! Unfortunately, the same inverter went again and this previous contractor couldn't send a tech out for 2wks. Knowing it would take that long to send a tech out. I decided to call Solar Help as they once replaced my hot water tank. They were extremely responsive and told me I just had to give them administrative rights to view my system from their office which was completed in 1 day! They got approval to order the new inverter and send a tech out within 1.5 weeks. They only needed to send 1 tech to do the job whereas the other contractor would always send 2 techs. Solar Help provided great professional service and saved me a big bill from HECO!!! Since it's been hot, I've had to use my AC system almost all day!! Thanks Solar Help!!

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.

I've had a Haleakala PV system since 2013. This year I decided to add a Battery Bonus system, and I…read moregot estimates from a number of companies, and once again chose Haleakala solar with a Tesla Powerwall. The sales person seemed pretty knowledgeable about both the product and the various options including Battery Bonus. He did a site survey, and confirmed my new equipment would fit into my desired enclosure. After paying my deposit, I received an initial design plan from them. I wanted to make some changes to the plan, which they quickly accommodated. They also submitted the plans electronically to DPP, and filled out and submitted the paperwork to HECO on my behalf. Couldn't have been easier, and took about 4 weeks. The coordinator sent a very complete outline of the various steps in the process, and an estimated time frame to complete them, so there was no surprises. My original panels had developed a squeak after many years of high winds; Haleakala came out and repaired the issue, including finding and fixing a crack in my Munir tile. My install was 2 weeks ago. The first day, they installed 9 new PV panels. The second day, they completed putting in the wiring and the new Tesla battery and gateway. About a week later, they returned to provision the entire system, which is operating now. Next step will be inspection and permit approval. I'm very happy with the sales process, design process, and installation so far. I have every reason to believe that they will handle the rest of the process shortly subject to when the inspector is available. My only issue to date has been that one of the circuit breakers they installed tripped the evening after the install. They ended up sending out a tech after hours to show me how to get back online, and then came back to address the issue permanently during the next appointment.

I submitted two online service requests regarding an issue with our Tesla battery not charging. The…read morefirst request was submitted on September 12, and I received a text message stating that someone would respond within 72 hours. Unfortunately, I did not receive any follow-up. Fortunately, the issue with our battery resolved itself. However, a phone call from Haleakala Solar would have been appreciated to acknowledge the request and offer support. I submitted a second request for a call on September 16 and again received a message promising a response within 72 hours. Once more, no one contacted me. This lack of customer service has been a reoccurring issue with Haleakala Solar. When we first installed our PV system six years ago we had issues with our solar water heater. Getting someone to answer and respond to our calls was very difficult. We finally received service when my husband drove over to their warehouse to talk to someone there.

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.
