Professional Team, Timely Installation, and Great Follow-Up

We recently had solar panels and batteries installed and had a really good overall experience. There were a couple of hiccups along the way, but the team stayed on top of everything and made sure it was all resolved quickly — even with their packed schedule before the Federal Tax Credit deadline. Their follow-up and commitment to getting everything done right really stood out. We’re very happy with how it all turned out and appreciate their hard work.

Sunspear Energy installation crew performed above and beyond.

Sunspear crew completed our 20x panel PV system in one day and went above and beyond to squeeze our battery into the garage. They even relocated a vent pipe so we could maintain a nice clean rectangle on our low slopes roof.

New EV charger and additional battery is sweet!

My wife's officially done with gas stations. This is our second go around with Sunspear. They were easy to work with and communicated every step of the way. She just got the Tesla, so we needed another batter, an EV charger, and a few extra panels to make it all work. We gave them our HECO bill and they figured out what we needed. I have my side of the garage. Zach came over to do a site inspection to figure out where to run the conduit to hide the wires so that the EV charger is on her side. Installation is great and my garage looks clean.

Excellent team to work with!

I cannot recommend Sunspear enough! After researching several companies, I chose them for my home solar project, and the experience was seamless from start to finish. The sales team was professional and transparent, taking the time to explain system sizing and financing without any high-pressure tactics. The installation crew was equally impressive. They arrived on time, respected my property, and completed the job ahead of schedule. Communication throughout the permitting and utility interconnection phase was proactive; I never had to chase them for an update. Great team to work with!

Our savings are incredible

My husband and I have a home with many air conditioning systems, 6 to be exact. Our electric bill over the past decade kept climbing upward to $2,000 a month. Sunspear Energy was not the cheapest solar company out there, but they were by a wide margin the most communicative and explained exactly what would happen after the point of sale. We currently have an average $50 electric bill monthly and we've effectively made back our original investment with our 6 batteries and 70 Sunpower solar panels. When we speak to family, we are adamant we got more than what we paid for.

Kaneohe HI batteries plus solar expansion

Sunspear helped me navigate an upgrade to my NEM system by adding batteries plus more solar panels, and the installation went great. It included a challenging service upgrade 200A, and they handled the coordination with HECO very professionally. They were able to get me locked into the Battery Bonus program too, so I got a nice incentive from HECO. Their commissioning team and Toy helped process everything very efficiently. Would highly recommend them.
