The Verdict

High Definition Solar is a gamble you shouldn't take. We found hundreds of reviews that split sharply down the middle: long-term customers who installed systems a decade ago and had warranty repairs handled smoothly, and recent prospects who describe aggressive door-to-door sales reps, no-shows for scheduled appointments, and pricing that one reviewer calculated at triple what a neighbor paid for a comparable system. The company excels at workmanship once you're on the roster (152 reviewers mentioned solid installation quality, and we couldn't find complaints about roof penetrations or wiring failures), but getting there means navigating high-pressure tactics and inconsistent communication. One couple reported their appointment slot given away because the wife didn't answer a callback within two minutes while working in surgery. Another homeowner discovered moisture damage under panels that three roofers said should have been flagged before installation. If you value transparent pricing and respectful sales conduct, this isn't your installer.

If you already have their system installed, you'll likely get decent warranty service. But if you're comparing quotes, the door-to-door pitch and erratic appointment handling suggest you'll spend more energy managing the sales process than evaluating the actual product. Explore other options.

3 Stories That Stood Out

1. Marek P.
Yelp | Nov 17, 2018 |

Marek P. shopped for a small rooftop system and ended up meeting two different sales reps on different days. He watched the first rep open with assurances about the company’s longevity, certifications and BBB record while skipping over the firm’s poor Yelp ratings, then pitch a system without even checking his actual energy use. That rep started with an average price of about $60,000 and whittled it down to roughly $37,800 for a 3.6 kW package — a number Marek found higher than a SolarCity quote for a much larger, 6.5 kW system. To sweeten the pitch the rep applied a promo code (PHP28, listed as $8,291 off) and a supposedly “initial visit” discount of $4,309 that was valid only that day, then layered a 30% tax rebate so the final presented price landed near $17,500 for that 3.6 kW system. He also pushed LG panels as premium, but Marek’s own research showed they were standard panels that can lose about 20% efficiency. Marek declined, and an office scheduler soon arranged a follow‑up with a “commercial” rep who promised a faster, better deal. That rep began at $32,000 and pared the price down to about $14,900 for what Marek recognized as the same system the prior rep had priced at $1

2. Brian F.
Yelp | Jan 23, 2022 |

Brian F. tried to set up a home solar consultation and his wife booked an appointment for 1/14/2022; they were promised a day‑before confirmation, but nobody called. When they reached out, a company representative shifted the blame onto them for not confirming. They gave the company a second chance and rescheduled for 1/22/2022 at 1:00 p.m. On 1/20/2022 a staff member called to confirm and his wife — both of them work as RNs in surgery — missed the ring because she was in the middle of an operation. She stepped out, called back within two minutes, and found their slot had already been given away. He walked away furious, calling it “worst customer service ever,” and questioned how the company would treat paying customers or handle future service issues — especially given an advertised A+ BBB status. The concrete takeaway: the company lost him over a missed confirmation and a two‑minute return call while a surgical nurse tried to respond.

3. Candice H.
Yelp | May 9, 2016 |

Candice H. hired the company for a rooftop solar install after a brief pre-inspection that, she says, focused only on sun exposure and trimming a nearby tree. Less than six months later, after she put the house on the market, a buyer’s inspection flagged that the roof needed replacement — and the worst damage sat directly beneath where the panels had been installed. Inspectors found moisture problems that could lead to fungus, and three independent roofers concluded the solar crew should have identified the roof’s poor condition before any panels went up. She ended up facing a stalled sale and a projected loss of at least $20,000 tied to repair and diminished buyer confidence. Candice believes the installation may have accelerated roof damage, and that the company’s original pre-inspection failed to prioritize the roof’s condition. She also disputes the salesperson’s claim that solar “appreciates” near the full investment cost, calling that expectation inaccurate. On the communication side, the interaction with the operations manager, Janae, left her frustrated: Janae responded late to time-sensitive emails, defended the company by pointing to a city sign-off (which Candice saw

What You Can Expect

01

1. Jill M.
Yelp | Feb 6, 2026 |

Jill had a 12-year-old solar setup from Hi Definition Solar, installed back in 2014, when one of the micro-inverters stopped working. She called during their busy season and still got a quick response: a technician happened to be in the area and came out to swap in the new part. Three days later, the system still wasn’t showing production, and Jairo Aguilar, the manager, stepped in and handled it that same day. Between the technician and Jairo, she ended up with four separate check-ins to make sure everything was actually working and reporting properly. That kind of follow-through stood out even more because this wasn’t their first job on the property — they had completely replaced the roof in 2015 and re-sloped it to send draining water to a better spot. She walked away with the sense that their crew didn’t just do the install and disappear; they kept after the details until the fix held.

2. John D.
Yelp | Aug 13, 2025 |

John's rooftop solar array, installed by Hi Definition Solar three years earlier on a steep, high roof, flagged a problem this summer when a notification showed the largest panel wasn't producing. HDS sent Marshall from their office to climb the daunting roof, find the fault and promise a warranty repair. Marshall handled the inspection calmly and quickly identified the issue, then returned as promised and spent five hours working alone to replace the wiring to each panel, redo the junction box and rewire the run down to the Enphase box at ground level. His professional, friendly manner and obvious command of the system reassured him, and he appreciated that the company stood behind the installation. The detail that lingered: a single technician completing a thorough, five-hour warranty repair on a difficult roof — the kind of follow-through that convinced him HDS backed their work.

3. Diego Cagigao
Google | Mar 30, 2026 |

Diego’s solar project began as a promising hillside installation back in early 2019, but the plan shifted and the panels ended up on his roof instead — 24 panels paid for in cash, enough for him to leave the company a glowing testimonial at the time. The trouble didn’t show up until December 2023, when a small leak appeared in his master bedroom. He patched it with tar to get through the winter, then emailed the company on March 28, 2024 about the leak near the panel area and heard nothing back. After a bigger storm, the bedroom turned into a water problem, and even then the follow-up was slow: one callback, a promise that their roofer would reach out, and then silence after the next storm passed. Fed up waiting, he brought in another contractor, who found that four solar anchors hadn’t been sealed correctly and had let the roof deck rot enough that the damaged wood had to be removed and replaced. In the end, the panels stayed put, but the roof over his master bedroom and office had to be rebuilt to undo the installation work.

1. Monique Miller
Google | Jan 15, 2025 |

Monique Miller had High Definition Solar install panels on her home in 2012 and enjoyed years of trouble-free operation until recently, when a roof tile broke beneath one panel and water started leaking into her attic, closet and bathroom. She called the company and discovered they only handle full-roof jobs — they could remove and reinstall panels but did not perform roof repairs. Local roofers told her they wouldn’t begin work until the panels were removed, leaving her stuck coordinating two trades. She called back and connected with Jairo Aguilar, who asked for photos, did some quick inquiries, and then called with a referral: a roofer she could work with directly to get the repairs done. The memorable part of the experience was Jairo’s follow-through — he went beyond the original scope to find a practical solution so she didn’t have to chase multiple contractors.

2. Shanshan Guo
Google | Jul 31, 2024 |

Shanshan had her solar system installed about five years ago, and the installer had been reliable from the start. When the array recently stopped producing any power, she contacted High Definition Solar; they dispatched a technician the same day, diagnosed the problem on-site, and restored generation quickly. The standout detail was the prompt, same-day service—five years after installation she still received fast, effective support that got her system back online.

3. SnakKing X.
Yelp | Dec 18, 2025 |

SnakKing X. bought a home already fitted with a two-year-old High Definition Solar system, and about a year later the entire setup quit working. When he tried to get help, the company brushed him off, saying it was too busy installing new systems to come out and fix a problem he would have had to pay to have addressed. The phone staff came across as rude and dismissive, but the bigger shock came later: two electricians found that High Definition had packed five hot wires into 1/2-inch conduit and pulled them so carelessly that one wire had 4 inches of insulation scraped away, likely enough to short the whole system. What stuck with him most was that the failure traced back to sloppy wiring inside the conduit, not just poor customer service.

1. Jill Martin
Google | Feb 6, 2026 |

Jill ran into trouble with a 12-year-old micro-inverter on the solar system Hi Definition Solar had installed back in 2014, and what stood out was how quickly they kept circling back until it was fixed. Even during their busy season, they found a technician already in the area, sent him over to swap in the new part, and when the system still wasn’t showing production three days later, they handled it the same day she called. Between the tech and the inside manager, she got four check-ins to be sure everything was working, which gave the whole repair a hands-on, stay-with-it feel. That same crew had also completely replaced the roof in 2015 and re-sloped it to move draining water to a better spot, so her experience with them spans both solar and roofing work on the same home.

2. Mike Brum
Google | Jul 19, 2024 |

Mike Brum has relied on a Hi Definition solar system at his home for 12 years. He finds the panels continue to perform well, and Hi Definition has stayed responsive whenever he needed help. The detail that stands out is the long-term support — help has been available not just at installation but again and again over more than a decade.

3. Chad Kraemer
Google | Jan 23, 2026 |

Chad had a smooth start with the installation, which moved along easily except for a few small gaps in getting all the needed information up front. The trouble showed up years later, when he needed help and ended up stuck with long waits just to get a technician on the phone and a service visit scheduled. What stuck with him most was the tone on the other end: he found customer service rude and condescending when he finally did get through.
