Howard M., a homeowner in Honolulu, was struggling with monthly electricity bills that reached $1,300. After receiving a referral from one of our satisfied customers, Howard reached out to Eco Solar Hawaii for a solution. Our solar consultant, Michael French, assessed Howard’s energy needs and designed a customized solar system to maximize his savings and efficiency.

We installed a state-of-the-art system featuring 46 Sunpower SPR-M440-H-AC panels, generating 20.24 KW DC, and three Tesla Powerwall 2 batteries with a total storage capacity of 40.5 KWH. Our team even devised an innovative solution to triple stack the batteries near the electrical meter, ensuring a clean and efficient setup.

With his new solar system, Howard is expected to save 3,400 kWh per month, equivalent to $1,360 in savings at $0.40 per kWh. The Tesla Powerwall 2 batteries contribute an additional $420 per month in savings by storing excess energy for use during peak hours or power outages. Howard took advantage of available financing options and incentives, including the 30% Federal and 35% State (capped) incentives, making the switch to solar more affordable. Today, Howard enjoys significant savings on his electricity bills and peace of mind knowing he has reliable backup power.

Everything was done to a T, from permit to install. Michael went above and beyond. With the batteries and solar, you don’t have to worry about power outages. Everything just clicks over to the batteries, whether it’s 5 minutes, 10 minutes, or night time – everything just works.

Justin and Tammie Drake, new homeowners in the Hoopili subdivision of Ewa Beach, met our team member Ben during a site assessment on a neighboring property. Ben collected their information and completed a site assessment that same day. Michael, one of our consultants, followed up to guide them through the process.

Despite the challenges of designing a system for a brand new home with no prior energy usage history, our extensive experience in Hoopili allowed us to create an accurate and efficient design. We installed 16 Maxeon 430 solar panels and a Tesla Powerwall+ with a backup switch, ensuring whole-home coverage and energy independence.

Our professional and friendly crew completed the installation in just five hours, impressing the Drakes with their workmanship. With their new solar setup, which includes 16 cutting-edge Maxeon 430 solar panels and a Tesla Powerwall+ with an integrated 7600-watt solar inverter and backup switch, the Drakes are expected to save an estimated $336 per month, or $4,032 annually, on their electricity bills. The Tesla Powerwall+ not only provides 13.5kWh of storage capacity but also adds an extra $140 per month in savings. With these combined savings, the Drakes can expect a payback period of just 4.7 years for their investment in clean, renewable energy.

I cannot believe that within 10 days of meeting we now have solar installed. The team of install guys were swift, respectful, professional and friendly. I highly recommend Eco Solar and if the stars went higher than 5, they’d get it! Mahalo Nui Loa!!!

Raymond Camacho first met the Eco Solar team at Oahu’s BIA home show. He had already done his research, and had determined that a Solar system would work best for his home. He had already had estimates from a couple of our competitors, and was holding off on installation due to the price. Ultimately he chose us not only because we were the more affordable option for installing the exact same products, but because we do the work ourselves (we never subcontract). Since Raymond’s Kapolei home sits in a better sunshine zone than most Honolulu homes, his system required fewer panels – and now saves him well over $3000 a year!

I knew that other companies provided the same products, but I chose Eco Solar because of their professionalism and the peace of mind of knowing that all of the work was provided by their employees (not subcontractors). I feel good knowing that I’m helping the environment and seeing a $17 electric bill every month doesn’t hurt.

Sean Bradshaw had been shopping around for a PV system to help offset energy costs for his young family and decided to call us based on the recommendation of a co-worker. Because he wanted the peace of mind with a great warranty, he chose a Eco Solar system. Before installation, the family’s annual energy usage was 8400 kWh (or about $3024). Today he has no electricity bills!

I would have to say Eco Solar’s team made the process easy and simple. They were able to answer all of our questions and concerns. The overall project from the signing of the contract to city & county permit and association approval to the actual installation of the PV system was a breeze. Eco handled it all and kept us informed throughout the project. I can’t say enough about how much we’re enjoying our system and the savings it’s providing. – Sean Bradshaw

Pearl City

Douglas Chu heard about Eco Solar through a previous customer of ours. As a recent retiree, he wanted a system that would require low maintenance while delivering high performance for years to come. We installed a system that maximized the Pearl City sunlight to deliver over 8900 kilowatts of energy per year – eliminating Douglas’ annual power bills of $3228.

The whole process with Eco Solar, from start to finish, ran very smoothly. The crew was nice and professional. We are very satisfied with the installation and savings. – Douglas Chu


Mike Rush was looking to immediately save money on his electric bill without having to borrow money or dip into savings for a system purchase. With a lease, he was able to cut his electric bill in half with no out-of-pocket expenses. Now, Mike is enjoying the benefits of the world’s most efficient solar panels and is on track to save over $63,000 over the next 20 years.

I was paying about $250 a month, now I’m paying $125. I basically locked in my monthly electric payment at $125. Effectively, it’s about half. It’s kind of a no-brainer! – Mike Rush
