I request a service for the week of August 22nd, 2025. It has been 4 months since the request service, but the solar is still not working. Is this the kind of service they provide to their customers? We have a loan of $80,000.00 for the 26 panels and 2 batteries and are still paying HECO an average of $300.00 since the connection. They said that our bill would be lowered to at least $30.00 a month, but we have never seen such reduction. I have complained before, and they mentioned high consumption was the reason. You based your calculation on the recent two months' electric bill to determine our needs, but you failed to deliver the promised $30.00 lower bill. My mom has been contacting them but there has been no response or call back. Both of us are frustrated with this long wait. I hope that this company will feel the same frustration that we have felt in 2026.

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.

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.

As we near the end of our install/upgrade, I felt compelled to reach out and sincerely thank the…read moreentire team for the exceptional work completed at my business. There were many aspects of the project--and, in particular, several individuals--that truly stood out to me. I wanted to take a moment to formally recognize their contributions and let you know how much we appreciate the professionalism, dedication, and pride they brought to the project. Merv has been nothing short of exceptional to work with. While he may be a man of few words, he certainly knows how to get the job done. He is highly motivated and takes tremendous pride in both his own work and the work of his team. His attention to detail is remarkable, and he consistently went above and beyond to ensure that we, as the client, were not only satisfied with the work but genuinely impressed with how each stage of the process was handled. Merv's combination of initiative, critical thinking, and ability to adapt on the fly makes him an invaluable member of the team. As we approach the completion of the project, he identified several details that I had personally overlooked. Rather than simply accepting them, he took it upon himself to ensure they were addressed before the project was finalized. That level of ownership and commitment speaks volumes about his character and work ethic. Individuals like Merv are instrumental in maintaining and strengthening the reputation that SunSpear has built. Blaine was my primary point of contact from the very beginning and played an instrumental role in bringing this project to SunSpear. We received four competing bids, and Blaine worked diligently to ensure that SunSpear remained competitive and presented us with a meaningful offer. His willingness to be transparent throughout the process immediately gave me confidence that I was working with someone genuine--someone who understood our priorities and treated them as if they were his own. Blaine took the time to understand the scope and complexity of what we were undertaking and worked closely with me to ensure that our needs were fully understood. His efforts ultimately led to connecting me with Taki, who was instrumental in taking the plan from concept to execution. There are not enough words to express how grateful I am for Taki. He has been an exceptional communicator, coordinator, and liaison throughout this entire project. Despite my being away on an extended vacation at the beginning of the project, Taki maintained consistent and proactive communication with me from start to finish. He provided an extensive project timeline that was executed remarkably close to plan, which gave me a tremendous amount of confidence throughout the process. Considering the extensive coordination required, coupled with the expectations of my team to maintain our day-to-day operations, Taki remained composed, organized, and thorough at every step. He has been an outstanding partner throughout this project and, quite frankly, made my job significantly easier. His ability to anticipate needs, communicate effectively, and keep everything moving forward was invaluable. Cory was another key contributor who helped make this project as seamless as it was. Through his coordination with his team, Cory worked closely with us to ensure that the project had virtually zero impact on our operations. He also helped identify and implement proactive measures that will benefit us as we move into future phases of the project. Cory consistently stayed on top of every detail and demonstrated a tremendous commitment to our success. His willingness to come in on a weekend to help us prepare for our tie-in is just one example of the level of dedication he demonstrated throughout the project. His efforts did not go unnoticed or unappreciated. All in all, Sunspear maintains an exceptional team of highly skilled and genuinely valued individuals. Each of them takes tremendous pride in their work and consistently strives to execute at the highest level possible. Their professionalism, ownership, communication, and dedication made a significant difference in the success of this project. We are incredibly grateful for the many hours of hard work, coordination, and commitment that they have invested in our property. The end result will allow us to operate in a more sustainable and energy-efficient manner, and we recognize that achieving that outcome required a tremendous amount of effort from everyone involved. Please extend our sincere appreciation to Merv, Blaine, Taki, Cory, and the entire SunSpear team. Their efforts have made a lasting impression on us, and we are grateful to have had the opportunity to work with such a dedicated group of professionals. With the addition of the SolarInsure program, we look forward to many years of continued collaboration and to building upon the strong partnership established through this project. Thank you again for an outstanding experience!

I will be honest and it was or maybe still as the transition from SunPower to SunStrong has not been the smoothest.

It took quite a while BUT in the end the work performed was done professionally and well. Much thanks to Zack for taking care of the initial request and getting the panels up to par. Many mahalos to Issac, Issac Jr and Isaiah for the care they took in removing and then reinstalling our panels for roof 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.
