The Verdict

ParagonSun handles the entire solar process without surprises or upselling. We analyzed reviews spanning eight years and found the same project manager, Cori, still answering calls and troubleshooting systems she installed in 2017. In 2024, when a Southern California Edison technician accidentally disconnected a homeowner's battery during a meter upgrade, Paragon had a tech onsite before the next day's heat wave hit. The household kept working with the AC running while neighbors lost power. Reviews show 86 mentions of proactive project management, including permit chasing, utility coordination, and same-day roof assessments. Sixteen reviews describe non-pushy sales calls where Cori explained tax incentives and interconnection agreements without rushing a decision. The company sources specialized hardware when standard parts won't work (clips for standing-seam metal roofs, replacement monitoring systems from Amazon when Enphase units fail). When problems surface years later, Paragon steps in even if they didn't install the original system. The $475 service-call fee is steep, but reviews show techs arriving on time, diagnosing issues in high winds, and leaving detailed explanations.

If you want an installer who'll troubleshoot your monitoring system six years after the panels go up, or dispatch a crew before a heat wave to fix what the utility tech broke, Paragon is worth the premium. You won't get the absolute lowest quote, but you'll get a project manager who answers her phone in 2025 about a system she sold in 2017.

3 Stories That Stood Out

1. Mark H.
Yelp | Jan 10, 2025 |

Mark H. has had a residential solar system for about five to six years and recently ran into a hiccup when his monitoring stopped working. Cori at Paragon took the lead, spending several weeks troubleshooting remotely and trying different fixes with him. When those attempts failed, she arranged for him to buy a replacement monitoring unit from Amazon for roughly $600. The part showed up within five days, a Paragon crew came for a service call, handled blustery winds, fussed over his dogs, and swapped in the new unit — restoring monitoring that same day. Cori, who has been his primary Paragon contact since installation, stayed engaged through every step, communicating clearly, isolating the issue, and following through to a practical, timely solution. He ended up with a working system after a relatively small out-of-pocket part and a single service visit — and a long-term company rep who stayed on the problem until it was fixed.

2. Fazri Z.
Yelp | Sep 9, 2022 |

Fazri decided in late 2021 to install solar panels and a backup battery on his home to lower electric bills and keep both him and his wife working during outages. A few months after the install, a heat wave and neighborhood power cuts put the system to the test. Just days before the heat wave, a SoCal Edison tech upgraded the meter and accidentally disconnected the battery, leaving them without backup. He called Paragon Sun and they sent a technician out promptly; the crew restored the battery system in time for the next-day outage. Because of that fast response, he and his wife kept their A/C running and were able to continue working uninterrupted. What stood out was Paragon’s high-touch service — designing the system to fit their needs and staying available months after installation to resolve an emergency that otherwise would have cost them a workday.

3. Richard Chamberlin
Google | Sep 13, 2024 |

Richard needed a replacement Enphase microinverter for a 10+ year-old PV system after his original installer went out of business. He called several firms that refused to touch systems they hadn’t installed, but ParagonSun stepped in and agreed to take over maintenance. Enphase mailed the warranty replacement to him, and ParagonSun dispatched Marvin, who arrived right on time and worked efficiently and cordially to swap the unit. Because the array is so old, a small glitch surfaced after the swap, but it cleared up quickly once he reported it. Throughout the process his main contact, Cori Larsen, handled questions before and after the invoice was paid, answering by the end of the day and sometimes within an hour. The service call fee was $475 — on the high side — but for a company willing to adopt an orphaned system and deliver that level of responsiveness, he judged it money well spent.

What You Can Expect

01

1. Mark Hodge
Google | Jan 10, 2025 |

Mark Hodge has run his home solar system for about five to six years and has been very pleased with its performance. When his monitoring stopped reporting recently, Cori at Paragon stuck with the problem for several weeks, methodically troubleshooting each error until they exhausted remote options. They ultimately decided on a replacement monitoring unit — he ordered a roughly $600 device from Amazon, which arrived within five days. A Paragon service crew came out, battled windy conditions, charmed his dogs, and installed the new unit; within one visit he was back to seeing real-time data. The lasting detail for him wasn’t the quick part replacement but that the same Paragon contact who’d supported him for years stayed engaged through troubleshooting and then coordinated the hands-on fix in the field.

3. Cecile W.
Yelp | May 30, 2024 |

Cecile hired ParagonSun for a two-phase install on her home and ended up with a substantial setup: 47 panels, seven batteries, and a dedicated EV charging panel installed between December 2022 and May 2024. The first system — 32 panels and three batteries — went live in December 2022, and she added a fourth battery in March 2023. A second system of 16 panels and three more batteries followed in May 2024. Systems from the first phase are operating under NEM 2.0; the second system was delayed until Southern California Edison issued guidance that would allow adding panels with batteries without forcing both systems onto NEM 3.0, provided the newer system is configured not to export; final utility approval on that setup is still pending. ParagonSun managed the job end-to-end: engineering drawings, permit paperwork, on-site meetings with the city inspector, submissions to the utility, and even coordinating roofers when System 2 required roof work. Cecile discovered that estimates held steady — the initial quotes matched the final bills — and electricians worked cleanly and efficiently; she singled out Josh for particularly careful work and appreciated the cosmetic touch-ups.

1. Joseph S.
Yelp | May 23, 2020 |

Joseph S. celebrated the first anniversary of an 8-panel solar installation and ended the year having produced slightly more electricity than he used. He had been apprehensive about the results before going forward, but the installation and activation proceeded smoothly and, once the system went online, he felt a real sense of power and control over his energy. Producing his own electricity gave him a tangible feeling of achievement and security, and the financial impact cut his utility bills down to almost “free” electricity. His only regret was waiting so long to make the switch, but he’s glad Paragon made it work — the small annual surplus of energy is the detail that keeps him satisfied.

2. jmstarkca
EnergySage | May 23, 2020 |

jmstarkca celebrated one year with solar and discovered the system produced just a bit more energy than they used. Looking back on the experience, what mattered most was how smoothly the install and commissioning went — Paragon Sun kept communication tight, each step stayed clear, and every milestone finished within the promised timeframes. The whole process felt unusually stress-free; steady updates and reliable scheduling meant no last-minute surprises or “curve balls.” After a year of clean production and an easy setup, they regret only that they waited so long to switch to solar.

3. Pete T.
Yelp | Aug 14, 2025 |

Pete T. ran into trouble when six of his rooftop solar panels stopped reporting. After struggling to reach his original installer by phone and through their website, he turned to Paragon. Cori at Paragon walked him through exactly what to do before the visit, stayed in regular contact while the needed parts were sourced, and kept him on task during the delay. The crew repaired the panels and completed the work for less than the initial estimate. He ended up with six functioning panels and remembers Cori’s clear guidance and steady follow-up as the standout part of the experience.

1. Paul Bresenden
Google | Jul 1, 2025 |

Paul's solar system was left without support when the company that installed it went bankrupt, stripping away the promised warranty. After dialing 12 different solar companies trying to get someone to fix the problem, he finally reached Paragon. Paragon returned the call promptly, arrived exactly when scheduled, and went beyond a basic repair to make sure the system was truly fixed. They even set a follow-up call a week after the appointment to confirm everything was operating perfectly. He now plans to rely on Paragon for any future issues and wishes he had found them sooner.

2. Patrick M.
Yelp | Jun 27, 2025 |

Patrick M. wanted to add solar backup batteries to his garage but hesitated because of the steep cost. He connected with Paragon Sun and Cori arranged for an electrician to come out for an initial assessment; the tech called right away and warned they couldn’t do any work because the main electrical box was actively sparking and catching fire. His own electrician of ten years showed up immediately, confirmed the danger, and sent videos that made it clear a house fire could have happened at any moment. Convinced by that discovery, he chose Paragon Sun; they handled city permitting, the installation, and system setup from start to finish. At the time their rating sat at 4.99, and what stood out most was how the inspection uncovered a hidden, serious hazard before any work began. He walked away relieved that the project not only upgraded his backup power but also likely prevented a major electrical fire.

3. Jimmy Lee
Google | May 17, 2025 |

Jimmy Lee worked with Cori to design and install a solar system with backup batteries on his home that also handles EV charging. Cori and her ParagonSun installation crew moved efficiently and delivered visibly high-quality workmanship, and once Southern California Edison signed off the system began running the house primarily on solar and the battery packs. He noticed that on heavier days—when the EV is charging—grid usage rises, but most of that draw happens during off-peak hours, which is expected. The key takeaway for him was predictability: by keeping daytime peak grid charging to a minimum, the setup meaningfully lowers bills while still supporting EV needs. He recommends talking with Cori about charging schedules and battery use during the design phase so the system performs the way he experienced it.

Long-term Satisfaction

Long-term satisfaction for ParagonSun holds steady at 5.0 ★. This is better than 87% of installers we looked at.

Long-term reviews carry the most weight in our methodology because they are most representative of what you should be paying for: a system that will perform for years.
