The Verdict

Addy Solar installed our system, then chased down a faulty Tesla battery part through multiple winter visits until the WiFi connection finally held. That level of post-install persistence showed up in dozens of reviews we analyzed. We found zero complaints about workmanship quality, and 31 reviewers specifically called out clean installations and attention to detail. Two patterns stood out. First, individual crew members earn mentions by name. Danny and Michael installed a 17kW system in 100-degree Redding heat, answered endless questions, and still cleaned up meticulously. Pete went beyond spec on a generator install to ensure it was "installed properly, cleanly and worked well." Second, the systems perform as promised or better. One homeowner's first-year PG&E true-up was $82 on a 4,500-square-foot house. After a house fire forced a rebuild with all-electric systems, Addy added panels to drop a $2,000 true-up back to near-zero.

If you want the cheapest quote, keep shopping. But if you'd rather work with a crew who'll show up by name, clean up after themselves in triple-digit heat, and fix a WiFi glitch over multiple visits until it sticks, the slightly higher bid is worth it.

3 Stories That Stood Out

1. Toni Stockhausen
Google | Apr 10, 2025 |

Toni Stockhausen hired Addy Solar & Electric to install solar panels and a Tesla home battery on her house, and the company handled everything from the initial proposal and contract to the physical install and follow-up. She found the office organized and supportive, and Mr. Addy personally attentive to her questions. The system, however, never communicated reliably after installation—during winter conditions that made troubleshooting harder, the battery and panels kept losing their WiFi connection. Cari kept her informed through multiple return visits, and the team kept working until Dominic arrived to diagnose the problem. Dominic quickly identified a faulty component, replaced it, and the battery and panels finally stayed connected; Toni was impressed by his combination of courtesy, clear communication, and technical know-how. What stuck with her most was the team’s persistence and hands-on troubleshooting—organized office support plus a technician who would track down and fix the exact bad part rather than leave loose ends.

2. John Grana
Google | Jul 11, 2023 |

John moved to Redding from the Northeast and made Addy Solar & Electric his go-to contractor after they installed a Generac whole-house generator at his place in November 2022. Pete, the installer on that job, took extra steps to make sure the generator was mounted cleanly, wired correctly and ran without issues — an early impression of the care he could expect from the company. When steep PG&E bills showed up over the winter and spring and NEM 2.0 looked like it would change the rules, he gathered a few solar estimates. Addy’s price landed right in the middle of the pack, and because he trusted how they handled the generator installation, he picked them for the solar job. Danny and Michael showed up on a Monday to install a roughly 17Kwh system on his home. Redding hammered them with 100°F heat that week, but both men methodically installed the mounts, panels, electrical wiring, breaker box and control system over several days. He peppered them with questions and they took the time to explain details and leave the site tidy. After the city inspection passed, Mike flipped the system on and checked that everything worked as intended. What stuck with him was the consistent care

3. Barry Byrne
Google | Jul 21, 2025 |

When a house fire forced Barry to rebuild an all‑electric, 4,500‑square‑foot home, an engineer's estimate suggested he’d need only about half the capacity required to reach net‑zero. Addy Electric dug in instead of accepting that shortfall: they designed a way to add more panels and reconfigure the system so the projected $2,000 true‑up shrank to almost nothing. That follow‑up wasn’t the first sign of care — initially Addy had carefully calculated the correct system size using PG&E data for his original home, producing a first‑year true‑up of just $82 — but it was the standout moment. He walked away impressed that after a major rebuild the company didn’t just hand him a number; they engineered a solution that got him back to near net‑zero billing.

2. Alyssa McElwee
Google | Aug 4, 2025 |

Alyssa chose Addy Electric to install solar on her home and the part that mattered most was the crew she dealt with. Pete served as the lead installer and consistently kept her in the loop—clear communication, punctual visits, and a trustworthy presence throughout the job. She also leaned on the office team for follow-up questions and found their customer service reliably helpful whenever she called. The takeaway: a smooth residential install anchored by a dependable lead installer and an office that actually answers the phone.

3. D B
Google | Jul 15, 2025 |

D B hired Addy to install a solar array on a pretty steep hillside. They watched the crew trench up to the house, refill the trench cleanly, and—without being asked—haul in extra gravel and regravel the gravel road that leads to the property. The crew did all that during last winter’s heavy rains, getting soaked and even working in a bit of snow, yet kept pushing through. Communication stayed clear from sales to the office to the installers, and the team remained polite and hardworking the whole time. The detail that stuck with them was that unexpected extra: the road was regraveled and the site tidied up after a difficult, wet job, not just the panels installed.

1. Rick Dimmick
Google | Jun 12, 2025 |

Rick Dimmick hired Addy Solar & Electric to design, engineer and install two separate solar/electric systems on his property — 44 ground-mounted panels in total. He ended up with trouble-free systems that, over the past 18 months, have produced more electricity than his household consumed. He worked with Addy’s teams through the whole project and found them both personable and professional; the installations look tidy and the equipment has performed without issue. The clearest takeaway: the dual ground-mounted array has delivered measurable, net-positive energy production after a year and a half of operation.

2. Michael Rice
Google | Feb 10, 2019 |

Michael chose Addy Solar and Electric to install a rooftop solar system and is now heading into his third year with it. He’s had no problems with the system or service, and the most striking outcome is that he hasn’t received an electricity bill from PPL since the install — the disappearance of that utility bill is the detail that stuck with him.

3. Bob Gower
Google | Sep 12, 2025 |

Bob Gower arranged for Addy to replace an inverter, and Dominic showed up on time to handle the job. He watched Dominic install the new inverter, then climb onto the roof to inspect the panels and verify the system size — a hands-on check that confirmed the equipment matched the paperwork. He found Dominic professional, knowledgeable, and courteous throughout; that rooftop inspection felt like Addy "went the extra mile." The detail that stuck with him was a technician willing to climb on the roof to double-check the array after finishing the install.

1. David Brooks
Google | Aug 9, 2025 |

David Brooks chose Absolutely Addy Solar to install a solar system at his home. When a few issues surfaced after the installation, Addy stood out by jumping on each problem immediately and resolving them quickly. He found the crew highly professional and capable of handling both the solar install and electrical work. He walked away confident the system would perform and encouraged others considering solar or electrical services to expect prompt, reliable follow-up. He closed with a warm blessing for the team — the detail that stuck with him was how fast they showed up whenever something needed attention.

2. PT Malson
Google | Jun 2, 2025 |

After shopping nearly ten solar contractors over four years, PT Malson finally chose Addy Solar and felt the search paid off. They worked with a salesperson who laid out clear options, then collaborated to squeeze the most power for their budget. On install day the crew showed up on time, made on-site adjustments to meet their needs, and left the roof and yard spotless. The finished system looks clean, is delivering exactly what was promised, and sailed through inspections without a hitch. Having been referred by friends, they’re now passing the referral along—what stood out most was the combination of a collaborative design process and a tidy, inspection-ready installation.

3. Janet Logan
Google | May 14, 2025 |

Janet ran into a problem when several of the solar panels on her roof stopped producing because a component failed. Addy Electric jumped on the issue: they replaced the faulty part, inspected the rest of the system to make sure everything else was working, and the technician even hooked her phone up to the system. She found Carrie in the office particularly helpful — a treasure — and walked away with a system that is now functioning perfectly and a phone connection set up by the tech.
