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.

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!!

    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.

From the initial quoting process through installation, I was thoroughly impressed with their team! I got quotes from three different, highly-rated vendors... Solar Tech was not only significantly lower, they were the best value. Cisco had a great technical understanding and was a phenomenal communicator, working hard to ensure they were providing a system that best fit our needs. They provided multiple viable solutions for financing the project and did a great job working through permitting in a timely manner. Their install team, Nainoa, Nakoa, Asa, Wes, Kevin and Sean absolutely crushed it on the install. They were professional, knowledgeable and did not mess around... installing a 22 panel system with 2 Tesla Batteries in under 6 hours. I would highly recommend their services for anyone considering solar on your home.

I explained to him what was going on. I scheduled an appointment, I told him I wouldn't be home when they are at my house. He told me they would call when they were there. The day of the appointment I was at work, I waited for someone to call , no call at all so I wasn't sure if they checked on my heater. I called Mark, left a message. No call back. So I called Peter, same left message nothing, no call back that evening the next day.... Nothing for days. Then I get a text with a bill, and asking me what my last name was. I text back please call me because I had questions what was done because we still didn't have hot water, still hot then cold. Communication with them is terrible!!!! Then when I did receive a call, I missed the call; called mark back, left message, again no call back. So this was frustrating so I called my plumber to check my water line if something was wrong they checked and said no. He said my mixing valve needed to be replaced, they couldn't do it, they told me the solar people should have checked on would have knew the problem. . So I called Mark and left a message of what needed to be done. How quickly he returned the call and told me it would be another $200 to replace it. So I asked him you bill me for painting the insulation, checked the solar etc. I question him about him painting the insulation then he asked me did you climb up to check...I can see it from my daughters window Mark! Anyways the plumber asked me why the anode was changed so many times? Anyways I called on my retired friend who was a repairman. He checked the solar, anode and said the mixing valve needed to be replaced, he was nice to pick up the valve for me and replaced the old defective one. I'm fortunate to have a friend that could do the repair! Now I have cold and hot water thanks to my friend!!!

I've…read moreused them for many jobs and meant to write praise for them, but it took some frustrating experiences to get me to post this one. Let me start with the praise that is well-deserved: 1) Solar panels and battery storage. My parents used them first, and Alternate Energy briefly monitored their solar panel production to find that one panel was not producing as well as the others - something my parents wouldn't have noticed. Fixed. Leeland was an amazing point of contact for us when we then added solar and batteries to our home. He sized it based on our current usage and didn't fuss when we asked to go bigger, knowing our usage would increase. During the pandemic we contacted Leeland again to ask about maxing out solar panels on our roof and adding another battery to our home - again, all done quickly, and done well. 2) Electric vehicle charger installation. We had one EVSE installed during the solar panel job, done for a very fair price (even by mainland standards). We later asked to have a second EV charger installed. This one had an issue in that it didn't show up in our Tesla's energy tracking. Trevor was amazing for contact and coordination (for this and other projects) - he noted that the technicians who had done the job were newer, and he got it working quickly. He also noted that they had installed the wrong kind of electrical outlet, as they had used an indoor outlet (although with a cover). He swapped it out for an outdoor outlet and fixed some minor damage that had occurred during the installation, all at no extra charge. I appreciated his thoroughness! 3) Solar water heater maintenance. Simple and fine. 4) Home ethernet wiring. This one isn't listed as a service that they do, but their electricians took the job and did an absolutely amazing job of adding ethernet to my rooms based exactly on what I asked for, and to the outdoors for security cameras. They mounted the cameras (I handled the angling) and even tried to fix a cover for one of my air conditioners that keeps sliding down. The cost of this work was significantly less than a "low voltage" installer had quoted. 5) Air conditioning repair. One of my AC units began to struggle, and the technician identified that the condenser unit would need to be replaced. We had some scheduling delays for this one, and I have to give a shout-out to Ginger on the phones and by email, who was empathetic, responsive, and incredibly helpful. After the job was done I noticed a water leak; I tried to trouble-shoot it on my own and eventually determined that the water was coming from behind the unit. The technicians came out, identified that they hadn't fully secured the insulation, and even tried to scrub away some of the water stains on my wall. If you're keeping track, that's a lot of jobs, and while two of them weren't all 100% perfect, the company ultimately identified the issues and made them right. So why the negative? It has to do with the billing. 1) For the ethernet job, we had discussed the quote and then noted in advance that if the job took longer than expected there could be a cost increase. A complication did occur, causing delay. I had received one bill at the start to pay a portion of the job before it started (which is standard), and then the second bill at the job completion seemed to include the added time. However, I was later told that I still had to pay the rest of the first bill. That would mean that the cost overrun was over 50% of what was quoted. It took multiple calls over multiple weeks to get this one resolved. The company ultimately cleared it and said that everything was paid, but that was a lot of time and stress. 2) The air conditioning repair job in which they had to return to fix the insulation and admitted to it being their error? I agreed to pay a service fee, and was given a positive response when I asked if the fee could either be reduced or waived if it was found to be related to the original job. The technicians usually leave a receipt of the work done before the final bill is sent to us, but we didn't get that, nor did we get a final bill to pay. We assumed that they took responsibility for their work and left it at that. 7 months later I received notice that "internal oversight" had occurred and I owed the full $575. I called in, was offered $150 off, and admitted I was unhappy; I said it might be reasonable to pay the time for the technicians, but they admitted it was their error. So the bill was reduced to $250 for the technicians' time, they confirmed I'd get a new bill, and then promptly terminated the call, without so much as a season's greetings or an apology. I won't be so dramatic as to say I'll never use them again, but I've gone from seeing what else I can possibly use them for to making them my last call. Save all invoices and get confirmation of payment completion in writing.

    This review is overdue…read more The 5 stars is for the work that was done not the process of the companies who took over. I will be honest and it was or maybe still as the transition from SunPower to SunStrong has not been the smoothest. This transition left those of us with contracts in limbo waiting to find out who does our servicing which in the end went to Sunspear Energy. 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.
