A Great Job by a Remarkable Team…read more Independent Energy Hawaii did a great job for us. This is a remarkable team of people who clearly know what they are doing and take pride in getting the job done right. What impressed me most was not only their technical knowledge, but their willingness to take the time to help us understand our system and how everything works together. We already had an existing NEMA backup system, and they worked to tie it into the new system so that it will continue to serve us when the grid goes down--which unfortunately happens fairly often in our area. The entire crew worked hard, paid attention to the details, and made sure things were done properly. Just as important, they were responsive when I had questions and helped me understand what I have and how to use it. My wife and I truly appreciate the effort they put into our home. It is reassuring to know that when the power goes out, we have a system that was installed by people who knew what they were doing and cared about doing it right. Mahalo to the entire Independent Energy Hawaii team. We greatly appreciate everything you did for us. ---James L.

We initially planned to hold off on installing a PV system until after replacing our roof because we weren't sure how sturdy our ceramic tiles were. In the meantime, I reached out to Sid and shared my goals and concerns. He and his team did a fantastic job designing a plan tailored to our needs. In all honesty, with a little gentle encouragement from them, this system turned out to be the best investment we've made--especially with all the storms and power outages we've experienced in Hawaii Kai. From the installers to the admin team, everyone at PV Tech has been fantastic and easy to work with. We are so happy with our system and the incredible support we've received!

The quote also included all the required documentation and permits required by HECO and other agencies. Electricians Justin and Shawn were thorough, efficient and neat.

Justin and Shawn deserve the highest praise for their technical knowledge and installation expertise. Justin also helped setup the Tesla App on the day the project was completed. The system and App are working fine. I highly recommend PV Tech.

Sean from Island Solar Service contacted me the same day, actually within an hour of me entering my information on their website. He was able to visit my parent's house the next day and provided me with a quote. We decided to replace the whole system, the panels and the water heater, since it was old. We were able to schedule the installation pretty quickly especially with a lot of homeowners trying to get their systems installed by the end of the year. Prior to the installation, Sean informed my mom of what needed to be done to prep the area for the install. Basically clean the area surrounding the existing water heater and the space needed. He called a week prior to confirm the install and to start the permit process. The team of installers arrived early that morning (7:30 AM) and was done by 1:00PM. They did a terriffic job. Through out the job they informed us as to what they were doing and were very professional. Once completed they went through the system to provide us with information and how everything worked as well as who to call if anything comes up. Overall GREAT service and value. Very painless process. I'd recommend Island Solar Service to family and friends.

We live in Hawaii Kai (aka The Valley of Darkness), and the power has gone out repeatedly over the…read morelast few years. Since Eco Solar installed our Tesla Powerwall and solar panels, I genuinely don't know when it happens. No flicker, no beeping, no hunting for flashlights, the Powerwall takes over instantly and the house just keeps going. More than once I've found out we were in an outage from a neighbor texting me. The lights never even blinked. We shopped around and got quotes from several companies before committing. Eco Solar came in with the best pricing, and by a pretty good amount. What I appreciated just as much is that the number didn't move, it was a single advertised price, and that same number went directly to the credit union that helped me with financing. Michael French is who we worked with, and he's the reason I'd send anyone here. He walked us through system sizing and the Powerwall without any pressure, answered questions I'm sure he's fielded a thousand times, and was honest about what did and didn't make sense for our roof and our actual usage. He stayed reachable after the install too, which in my experience is exactly where a lot of companies go quiet. The install by the team happened in a single day, and all the permitting and paperwork was taken care of by the office staff, I barely had to do anything myself aside from the finance setup. The install is super clean and my neighbors have come by and asked who we used since it looks so professional. If you're a fellow Hawaii Kai resident and tired of the outages, or just tired of what you're paying HECO every month, ask for Michael. Can't recommend them enough.

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 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.

The work is solid, the installs are well planned and look nice. However, HSR's terrible at responding to other inquiries and repair requests. Their tech line almost always leads you to a voicemail that will never be replied to. Online requests go ignored. I've literally gotten spam emails from Haleakala saying "let us know how we're doing" that go unanswered. Sometimes I end up begging Enphase, the equipment vendor, to get Haleakala to respond. My core problem is that my system's reporting in terms of production and usage is way off from what HECO reports. According to Enphase, I'm sending a net surplus of power back to the grid monthly, meanwhile my latest electrical bill is over $200! That's with 30 panels AND battery backup! I want to get to the bottom of this. I'm guessing they have staffing issues, like everyone. And honestly, if I got an answer copping to that, I'd have more understanding. Instead it's radio silence. It's a shame because the product is good.

I rarely leave reviews like this, but after nearly three months of trying to get my solar system…read morerepaired, I am beyond frustrated. Alternate Energy installed our 36-panel system about 12-13 years ago. For years, we were happy with it. Our electric bills were incredibly low--even occasionally around $17 despite running A/C constantly. When we've needed help in the past, Alternate Energy wasn't always quick to respond, but they ultimately got the job done. Unfortunately, our recent experience has been completely different. I noticed our electric bills climbing and eventually checked the solar app and realized something was wrong with our system. Our electric bill in April was $321.33. By May it had increased to $458.66. June 3: An Alternate Energy technician came out and diagnosed a bad inverter. We were quoted $500 for the first hour of labor and $300 for each additional hour. The inverter itself was covered by the manufacturer, but we were responsible for labor. June 30: The technician returned and installed the replacement inverter. Great--or so I thought. I checked the app afterward and the panels still weren't showing that they were working correctly. I called and was told to give the system a few days to reset and call back if the problem continued. It continued. After more calls and difficulty connecting with Shyla, the person handling our service, I was told the technician needed to come back, get on the roof, and diagnose what was wrong with the panels. The next available appointment was July 30. The technician arrived. I expected him to inspect the panels on the roof. About two hours later, I realized I hadn't heard anyone on the roof, went outside, and discovered the technician and truck were already gone. No one had knocked on the door or explained what had been done. When I eventually spoke with Shyla, I was told he had worked on the inverter.The brand-new inverter that had just been replaced a month earlier.At this point I was completely confused, so I asked for something very reasonable: please email me a recap of the work performed so far, what has been found, and where we stand. Shyla agreed she would send it. I still haven't received it. I was then told the technician would need to be scheduled AGAIN after Shyla spoke with the solar panel company. Since then, I've made multiple calls and left multiple messages for Shyla trying to find out what is happening and what the plan is. Today, August 28, I called again. I was told Shyla was at lunch, and the person I spoke with assured me she would have Shyla call me back. I explained how frustrated I was and how long this had been going on. By 3:20, I still hadn't heard anything, so I called again. This time I was told Shyla was on another call and I could leave another message. I asked to speak to a manager and was told Shyla is the manager. I asked for her manager and was offered the opportunity to leave yet another message for someone else. No one called me back by the end of the business day. And while all of this has been happening, here are our actual electric bills: April: $321.33 May: $458.66 June: $615.96 July: $947.98 August: $877.61 That's $3,221.54 in electric bills in five months. I understand that equipment fails. I understand that a 12-13-year-old solar system may need repairs. I understand that parts have to be ordered and technicians have busy schedules. What I don't understand is why, after starting this process on June 3 and having Alternate Energy technicians at our home THREE times, I still don't have a clear explanation of what is wrong with our system, what needs to be done to fix it, when it will be fixed, or even the written recap of the work I've already requested. We've been Alternate Energy customers for more than a decade. I shouldn't have to repeatedly chase down a company we trusted with a major investment just to find out what is happening with our repair. I'm sure Alternate Energy is very responsive when someone is interested in purchasing a new solar system. I wish their service after the sale made an existing customer feel equally important. At this point, I don't need another apology or another promise that someone will call me back. I need someone with the authority to take ownership of this situation, explain exactly what has happened so far, and give me an actual plan to get our system working again.
