Real families, real results. See how Hawaii homeowners are saving with solar, battery, AC, and more.
“Our bill went down to $18 a month. Installation was done in just one day.”
“Our bill dropped from $600 to $200 a month. We couldn’t be happier with the system and the whole experience.”
“My bill went from over $200 down to $18 a month — even after adding two AC units.”
“We went with AEI because everything was Mitsubishi. We’ve referred four friends already.”
“They really focused on quality. Appreciated that they use only top-tier products and stand behind their work.”
“My wife and I danced when we got our first bill. No pressure sales, smooth installation.”
“I was skeptical about solar without the federal tax credit, but the numbers still made complete sense. My bill went from $350 to $22.”
“The whole process was seamless. They sized our system perfectly — we even have enough to charge our EV and run the pool pump.”
“The Mitsubishi mini-splits are so quiet you forget they’re running. Our bedrooms are finally comfortable and our electric bill barely changed because of the solar.”
“We started with solar hot water before going solar PV. The payback was incredible — under 3 years. Now we’re adding panels too.”
“The BYOD+ program was the deciding factor for adding a battery. Getting paid $2,000 upfront plus monthly credits — it was a no-brainer.”
“From consultation to power-on, everything was professional. The in-house crew was respectful of our property and cleaned up every day.”
“Living on Maui, power outages happen. Our Powerwall gives us 100% peace of mind. Plus the peak-rate export credits are fantastic.”
“33 years in business says everything. These guys know what they’re doing. Our system was designed perfectly and the AC keeps us cool without breaking the bank.”
“I called three companies for quotes. AEI was the most thorough and honest about what I needed. No upselling, just the right system for my home.”
After 33 years and 10,000+ installations, we have one of the largest review histories of any solar contractor in Hawaii. We are not a company with 20 carefully curated testimonials — we have hundreds of reviews from real customers on independent platforms where we cannot edit or remove anything.
280+ reviews across Google, Yelp, Facebook, and BBB — over three decades, through industry downturns, policy changes, and a pandemic. We are still here, still installing, and the vast majority of our customers would hire us again.
“Quality work at a fair price. My AC is so nice to have right now and the PV keeps my bill down!”
“I paid $1,500 to cancel with another company and switched to Alternate Energy when they could not tell me what PV panels were being installed.”
“The installation crew impressed me. Papers signed in late December, system operational by early January. Our bill dropped from $400 to $27.”
“They installed PV panels, energy boxes, and a solar heater — all excellent. Always respond ASAP. They are the best.”
Not every one of our 10,000+ customers had a perfect experience. We heard the feedback and made changes: a dedicated PV Tech Support line, 24-hour acknowledgment on service requests, and a commitment to respond to every review on every platform. A company that only shows five-star reviews is hiding something. We would rather you read all 280+ and decide for yourself.
