The Verdict

Coastal Solar handles the core install well but stumbles on paperwork. We found 82 reviews praising their workmanship without a single complaint about quality, and in one case, a technician named Taylor drove out the same day a homeowner called, diagnosed the issue, and fixed it within 30 minutes. The installation crews are clearly skilled. What sets them apart is follow-through after the job. When one customer's LG panels developed a manufacturing defect years later, Taylor returned, navigated the warranty claim, and swapped out the faulty panels at no charge. But that same homeowner initially spent six months chasing the company for a state rebate application that kept getting dropped. Once someone at Coastal picks up your issue, they solve it fast. The risk is that your issue sits untouched for weeks while you send unanswered texts. If you want clean roof work and same-day service calls when equipment acts up, Coastal delivers. Just be prepared to follow up on anything involving permits or rebates.

If you can tolerate some communication gaps on the administrative side, you'll get a solid install and impressive long-term support when hardware fails. If timely paperwork matters as much as the quality of the roof work, you may want an installer with tighter project management.

3 Stories That Stood Out

1. Adan Valencia
Google | Feb 28, 2023 |

Adan shopped 3–4 bids in 2019 and chose locally owned Coastal Solar—they were the mid-priced option—because he wanted to keep the work local rather than go with a cheaper, big-name company tied to Costco. He ended up with a large residential system and watched the installation unfold without drama: a casual, no-pressure owner (Matt) who approached the sale differently than the other firms, respectful installers who treated the family and home well, and a project that finished stress-free. Over the following years a few small hiccups popped up—nothing unexpected for a big system—but whenever he reached out Matt picked up his call or answered a text personally and usually solved the problem within minutes. On one recent visit someone came out the same day and upgraded the part in question at no charge. He has steered multiple friends to Coastal, several of whom also chose them and reported similar satisfaction. The detail that stuck with him most: direct access to the owner and same-day, no-cost fixes that a corporate provider likely wouldn’t have offered.

2. Russ E.
Yelp | Oct 30, 2023 |

Russ hired Coastal to install solar panels on his home and later had them add Tesla Powerwalls. He found the pricing reasonable and the initial installs went smoothly. A few years on, several LG modules developed a manufacturing defect; Taylor stepped in, coordinated with the manufacturer, and arranged quick replacements that were covered under LG’s warranty. He appreciated that Coastal handled the paperwork and the actual replacement work efficiently, turning what could have been a long, frustrating process into a straightforward repair. The detail that stuck with him was Taylor’s follow-through—prompt, hands-on warranty management that fixed the problem without hassle.

3. Jay Johnson
Google | Sep 30, 2024 |

Jay phoned the office at 10:30 a.m. about an issue and received an email from Taylor within the hour. By 3:00 p.m. Taylor arrived at his house and had the problem resolved in roughly thirty minutes. The thing that stands out is the speed — same-day contact and an on-site fix completed that afternoon.

What You Can Expect

01

1. Matt Lopuck
Google | Mar 11, 2025 |

Matt Lopuck has relied on Coastal Solar since 2013 and found a consistently personal, family-run approach to servicing his home system. Over the years he turned to the Riege family — and their Matt in particular — whenever something needed attention: swapping an inverter, adding extra panels, or getting Wi‑Fi production monitoring up and running. They handled each task promptly and followed up with the kind of hands-on care that feels more like a neighbor helping than a big company fix. The moment that stood out most was when they prepared a detailed report for his insurance claim and didn’t charge a cent for the work — a small, unpaid effort that convinced him no other local solar outfit matched their level of service.

2. Arlen Ring
Google | Jun 13, 2024 |

Arlen chose Coastal Solar to install a complex solar system on his home six years ago. Over those years the company stayed reachable for questions and stepped in to help troubleshoot issues whenever the system threw a curveball. He liked that they didn’t disappear after the install but remained a practical resource for problem-solving. What stuck with him was their willingness to provide hands-on support and troubleshooting six years later.

1. Cindy Hauser
Google | Jan 7, 2026 |

Cindy had her solar installed in 2022 on a home where the panels ended up looking sharp and have run without a hitch ever since. When her electric bill suddenly shot up, she was frustrated and close to the end of her rope trying to sort out why, and Grace and Adrian stepped in to help her dig through the problem. They eventually traced the issue to the utility side, but they still treated the situation with real patience and said they would keep watching her panels from their end in case anything changed. What stood out most was how willing they were to explain the system in detail and stay involved even when the problem turned out not to be theirs, which left her with a company that made the roof look good and the support feel just as solid.

3. M R.
Yelp | Apr 12, 2023 |

M R. had a 4 kW solar array and a 10 kW LG battery installed on their home. The crew showed up professional, the installation looked solid, and at first they recommended the company to friends — but the post-sale paperwork turned the experience sour. The sticking point became the SGIP rebate for the battery, a time-sensitive state program that the vendor, not the homeowner, must submit for. An employee began the application after install but got reassigned to field work with no hand-off, and the application stalled. They spent months calling, texting and emailing their point of contact, Matt Reige, with no meaningful progress. After a week and then another week passed with nothing submitted, frustration grew into repeated updates: by 09/20/2022 the SGIP still hadn’t been submitted; three days later they received confirmation that SCE had the application and it still awaited review; on 10/04 the application was returned for clarifications, and on 10/05 Matt emailed that he was working on updates. Then silence — multiple status requests between October 11–14 went unanswered. The homeowner finally threatened a negative online review; Matt called and promised the application would be

1. Laurel W.
Yelp | Sep 11, 2019 |

Laurel W. hired Coastal Solar to outfit her home with solar panels almost ten years ago, and the system has cut her electricity bill to zero — it regularly runs the air conditioning and charges two electric cars. She picked a local, family-owned contractor that did more than rack panels: the crew completed all the electrical work and coordinated a roof replacement so both projects finished together. They also dug into incentives, identifying the tax rebates she qualified for and calculating the precise panel tilt needed to meet SCE’s rebate requirements. Across a decade she encountered only a couple of minor part failures; Coastal Solar answered immediately and repaired them at no charge. The memorable takeaway is a long-running, bill-free system paired with a team that handled roof coordination and rebate details up front and kept supporting the installation years later.

2. Ben Rogers
Google | Feb 12, 2026 |

Ben came to Coastal Solar with a system that had gone offline after being installed by someone else, and the difference was immediate. Within a day, they had tracked down the problem and gotten his solar back online, turning a frustrating outage into a fast fix that restored the system without dragging the issue out.

3. Lynette Hardesty
Google | Feb 3, 2026 |

Lynette found the whole Coastal Solar experience unusually smooth, from the first conversations through the installation itself. What stood out most was how well Matt, Brandon, and the installer crew stayed in sync, with clear communication during the project and again years later when questions came up. On a house she clearly cared about upgrading well, the solar system ended up being the best improvement they had made, and the lasting support was just as memorable as the clean install.

Long-term Satisfaction

Long-term satisfaction for Coastal Solar drops to 4.0 ★ compared to early reviews. This decline is worse than 72% 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.
