The Verdict

Hawaiian Solar will handle the installation beautifully, then vanish when something breaks. We analyzed dozens of reviews and found a clear pattern: 18 reviewers praised flawless project execution, friendly crews, and timely installs. One homeowner completed three separate solar projects with them over several years, calling out every team member by name. But 10 reviews describe what happens after the honeymoon ends. One customer waited five days without hot water on a system still under warranty, with no technician available even for inspection. Another was billed $2,619 for a one-hour pool repair, charged for four hours at $232.50 per man-hour. A third expected a roof inspection during a service call, watched technicians leave after 15 minutes, then received a $200 bill for the visit they were told would be free. The workmanship scores well (16 positive mentions, only 4 negative), but post-sale support splits nearly three-to-one negative. If something goes wrong six months in, you may spend weeks chasing a callback. (One reviewer noted the company threatened that non-payment would put them out of business, which is not the reassurance you want from your solar installer.)

If you never need follow-up service, you'll love them. But if a panel leaks or a tank fails after install, you're gambling on whether they'll show up.

3 Stories That Stood Out

1. Peggy P.
Yelp | Dec 10, 2017 |

Peggy P. hired Hawaiian Solar to install a solar water heater at her Kona home and then kept coming back to them for a photovoltaic system; by early 2018 she was preparing to add a solar pool-heating array, too. She found Beth, Terry, Art, Ross, Eric, Dane and owner Ken Bloom consistently friendly, considerate and professional — people she trusted and enjoyed working with. The crews delivered as promised: they showed up on schedule, finished each job efficiently, and kept her informed every step of the way, so she always knew the status and what to expect. What set the experience apart was the combination of reliable, timely work and a personal touch that Peggy describes as embodying the Aloha Spirit; she also appreciated how quickly they produced a quote when she reached out. If she could give more than five stars, she would — the punctual crews, clear communication, and steady follow-through are the details that stayed with her.

2. Tammy S.
Yelp | Jan 4, 2021 |

Tammy S. bought a brand-new solar hot water heater for her island home 11 months ago. When the unit failed four days ago, she called the company this morning only to learn the earliest a technician could come was tomorrow — which would leave her without hot water for a fifth straight day. She ran into slow, unhelpful customer service and found the scheduling delay unacceptable for a recently installed system. Frustrated, she pointed out there are other honest companies on the island and urged others to choose differently. The detail that lingers: a under‑one‑year system that failed and the company’s response meant nearly a week without hot water.

3. Mary V.
Yelp | Jan 13, 2018 |

Mary V. had solar panels on her pool for three years and this was the second time she needed a repair. Two technicians arrived and finished the fix in about an hour, but the invoice arrived at $2,619.80. The bill lists labor as two technicians for four hours at $232.50 an hour — a labor line that adds up to $1,860 — which felt wildly out of proportion to a one‑hour visit. She left the interaction frustrated by the billing method and the size of the charge, and would warn prospective buyers to watch labor hours and per‑technician rates on their invoices.

What You Can Expect

2. Jason
Google | Jul 2, 2025 |

Jason hired the company to replace a solar hot water heater as one component of a large reroof project on his home. He found the team professional and accommodating, and credited Beth with keeping communication smooth and handling details so effectively that the heater swap became the easiest part of the whole job. The crew completed the replacement without drama and adapted to the project’s needs, and he closed with a grateful Mahalo. The standout detail: Beth’s hands‑on help turned what could have been a scheduling headache into the simplest item on the remodel checklist.

3. Marian Hughes
Google | Dec 6, 2024 |

Marian Hughes called the company after her electric bill jumped, expecting the same hands-on check she’d gotten years earlier when technicians climbed onto her roof, inspected the hot water heater and told her it needed replacement. This visit unfolded very differently: techs did not go on the roof, suggested her garage refrigerator might be the problem, stayed less than 15 minutes and told her the appointment would be free. A few days later she received a $200 bill despite no hot water-tank inspection. After pushing the manager for answers, she asked to speak with the owner and was told he was on vacation; she’s refusing to pay until she can discuss the unexpected charge directly with him. The standout detail: a short, sub-15-minute visit promised as free that turned into a $200 bill with no roof inspection.

1. Jacob T.
Yelp | Jun 23, 2019 |

Jacob chose the company to install solar hot-water systems at both of his homes; the tanks are now about 12 years and 8 years old. He found the systems still performing well, and whenever he needed service over that stretch technicians arrived promptly, were friendly, and handled repairs efficiently. The detail that sticks is durability paired with consistently quick, personable service — even after a decade on one of the systems.

2. Theresa D.
Yelp | Nov 15, 2025 |

Theresa D. hired Hawaiian Solar to handle a full hot-water upgrade on her Big Island property — a new hot water tank, rooftop solar hot water panels and a solar-fed pool heater. She came away calling the whole job one of her best experiences with a Big Island company. The crew arrived when they promised, completed the work exactly as bid and stayed on a tidy, timely schedule; they worked steadily, treated the house and yard as if they lived there, and remained respectful and professional throughout. Office staff and field workers alike kept communication smooth, but what stood out was manager Beth’s upbeat, accommodating manner — Theresa could practically feel the smile through the phone, which made scheduling and questions effortless. In the end she ended up with a functioning home and pool solar hot-water system and a memorable customer-service touch that turned a technical installation into a low-stress experience.

1. David E Deutsch
Google | Apr 7, 2025 |

David Deutsch ran into a run of bad luck: two separate components in his solar hot water system failed due to factory defects, and an installation-timing issue forced a roof replacement (not the company’s fault). Hawaiian Solar and Plumbing stayed calm and helpful through it all — they replaced the defective parts, coordinated around the roof repairs, and never once got snarky or difficult. He found the crew consistently fast, punctual, and unusually tidy on the job; they explained steps clearly, were easy to work with, and stood behind their work. What stuck with him was their steady “aloha spirit” and willingness to support the system through multiple setbacks without complaint — and that they left the site clean and the system functioning when it was done.

2. David D.
Yelp | Apr 7, 2025 |

David hired Hawaiian Solar and Plumbing to install a solar hot water heater on his island home, and what started as a routine project turned into a run of bad luck: two separate components failed because of factory defects, and an installation-timing complication meant his roof had to be replaced — a repair that wasn’t the company’s fault. He found the crew unfailingly respectful and imbued with an aloha spirit; they replaced the defective parts, coordinated around the roof repairs, and never became snarky or difficult. Throughout the ordeal they stayed fast and punctual, kept the worksite remarkably clean, explained what was happening, and made scheduling painless. In the end he appreciated that they stood squarely behind their work—handling manufacturer failures and accommodating a major roof repair without drama—and the detail that stuck with him was how calmly and kindly they managed a messy situation so the system ended up working as intended.
