    Scott Sparkman and his team installed a complete solar system for me with batteries about 7 months ago.

With…read morea fantastic warranty and quality installation, timely responses when we had any questions, I would definitely highly recommend these guys! For price, I feel like they were one of the higher quotes we received, but you get what you pay for. What sold me was the lengthy warranty that will still stand even if the company, or panel and battery manufacturers go out of business. We've had our system close to a year now and we've had no issues... the customer service team there cannot be beat as they respond promptly to any questions or concerns we may have. I also appreciate the fact that there was no high-pressure sale... just respectful and timely communications. Definitely worth calling them for a quote.

    I'm giving 3 stars because the final system is now up and running, and Leit, the lead…read moreinstaller/electrician, was excellent. My project was the installation of a Tesla Powerwall and the addition of new panels to my existing solar system. Leit was responsive, professional, explained what was going on, and was honestly the only bright spot during the final part of the project. He deserves a lot of credit for stepping up and getting things finished. That said, the scheduling and communication around the final commissioning process were extremely frustrating. The appointment changed multiple times, and I was given conflicting information about when the crew would actually be coming. At one point, if I had not reached out to Leit directly myself, I would have been waiting around with no update. The Powerwall and added panels appear to be working properly now, and I appreciate the quality of the install, but the coordination and communication definitely need improvement. Leit was excellent, but the overall project communication could have been much-much better.

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.

    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.

    Update: Confirmed; they no longer support the products they sold just 5 years ago. Not a warranty…read morework issue--they lost their certification to do the work, or let it lapse. Junk product from a junk company. Original: SolarTech Hawaii does not support the equipment they install. Do not recommend; as other reviews have mentioned the poor support after sale is unacceptable.

When I first contacted them, they were very responsive, came out to our house multiple times to check it out, and even offered very reasonable and competitive pricing. Installation had a few hiccups because our house is old, weird, and probably very hard to work with, but we're very happy with our system. All the kinks that the team had to work through were fixed/solved in a very timely and quality manner. The only problem we had was getting updates between signing our agreement and installation. Understandably we waited pretty long to hear anything about installation due to the overload all solar companies were experiencing due to the federal tax credit being cut next year. Our drawings were back logged, not because of HI Power, but because of the approvals they were waiting for. But I had to reach out to multiple people at multiple times before someone could explain this to me. This really stressed us out for a bit that no one was getting back to us, but once they explained all the issues they were facing, everything worked out perfectly. I would still like to recommend this company compared to other bigger companies based off of my parent's and grandparent's experiences.
