The Verdict

The Solar Pros will chase down your original installer's mistakes and fix them right. We analyzed dozens of reviews and found a striking pattern: roughly one in four customers hired Mario after another company damaged their roof or left faulty equipment. One homeowner spent six months fighting a $600-per-month electric bill because their original installer wouldn't replace a broken inverter. The Solar Pros diagnosed it and swapped in a new one within days, complete with monitoring software the first company never mentioned. Another customer had 26 panels causing multiple roof leaks. Mario inspected the damage the next day, temporarily patched the worst gaps during that first visit (with spare tiles from his truck), then tore out and reinstalled the entire system with better materials and a 10-year workmanship warranty. Reviews consistently mention his crew starting work within 48 hours while competitors quoted four to six weeks. We did find six reviews alleging shoddy subcontractor work and unresolved electrical problems, so the company isn't flawless. But 36 reviewers specifically praised the team's competency handling both roofing and electrical work, and post-installation support earned a 4.5 score with just five negative mentions.

If you want the cheapest quote, keep shopping. But if you need someone who'll fix another installer's roof damage or troubleshoot a faulty inverter after hours, The Solar Pros is worth the call.

3 Stories That Stood Out

1. James M.
Yelp | Mar 5, 2024 |

James had already lived through the worst kind of solar job: 26 panels installed by another company that left his roof leaking and damaged, with interior water getting worse after every rain. When he started searching the East Bay for someone to undo the mess, Mario stood out immediately. He answered his own phone, gave straight answers, got out to inspect the next day, and sent over a bid in days instead of the weeks other companies needed. During that first visit, he even stopped one of the worst leaks on the spot and swapped in a few broken tiles from his truck, just to keep more water out while James figured out the next step. He also kept the price in line with the other bids, but moved much faster and already looked more capable than the rest. Once the job began, the difference kept showing up in the details. Mario checked in daily, photographed the roof damage for James’s lawyer, and tracked the reinstall as the crew worked. They started almost immediately, came back on a Sunday when the rain let up, and used better materials than before, replacing old tar paper with high-temp peel-and-stick underlayment. By the end, the roof no longer leaked, the frame system went back on,

2. Paul X.
Yelp | Aug 26, 2025 |

Paul X. had already spent more than six months fighting with the company that handled his panels after a faulty inverter shut the system down and his electric bills climbed by about $600 a month. He got stuck in endless back-and-forth, sending photos and hearing scripted explanations, even being told that a low bill somehow meant the panels were working — a claim that left him more frustrated than informed. By the time he reached TSP, he was ready to stop chasing answers. They quickly found the inverter problem, replaced it within days, and set him up with an app so he could finally watch the system’s output himself. They also pointed out a few broken roof tiles that were letting water through and offered to take care of that too. The part that stands out most is how he ended up with not just a working inverter, but a monitoring setup he had never even known existed, after months of feeling stuck in the dark.

3. Dorothy W.
Yelp | May 14, 2024 |

Dorothy W. ended up in a fraught mess after a solar installation that was handled by subcontractors working under Powur, including crews tied to names like The Solar Gurus and The Solar Pros. What should have been a straightforward job on her home turned into three separate service visits, each one followed by new electrical trouble: outlets failing across the house, appliances like the oven losing power, and electricity cutting in and out before stopping altogether. She came away convinced the work had been done by an unqualified crew that arrived in a truck and left the house worse than they found it, then refused to accept responsibility when the problems kept returning. The most frustrating part was the payment timing — she had already been asked to pay in full before inspection, so once the damage showed up again, she had no leverage left while she waited for yet another response from the same people who had already been back three times.

What You Can Expect

01

1. Scott G.
Yelp | Dec 3, 2025 |

Scott found himself working with Mario and the TSP team on a bigger home upgrade that bundled roofing, extra solar panels, and a battery install all at once. What stood out most was how coordinated the whole project felt: different crews handled the roof first, then came back for the panels and battery, while Mario stayed responsive to questions and laid out a detailed estimate that made the work easy to follow. They also pulled out the old solar converter, tied the entire system together, and spent real time showing him how the new setup worked and which configuration choices would squeeze the most value out of it. By the end, he had a roof and solar system that were fully integrated and a clear understanding of how to run them.

2. Christina W.
Yelp | Oct 11, 2025 |

Christina W. reached out over a safety concern with a few power outlets in her home, and Mario had his crew there the same day. The team inspected everything, walked her through what was going on, and helped replace several outlets on the spot. What stood out most was how quickly a roofing-and-solar company stepped in to handle an electrical issue without making it feel like a hassle, with Mario and his team keeping the job reliable and efficient from the first call to the final fix.

1. Asad F.
Yelp | Oct 24, 2025 |

Asad had already put solar panels on the house, so this was a battery add-on rather than a full rooftop project, and Mario’s team made the upgrade feel almost effortless. They arrived on schedule, handled the installation in a single day, and kept the whole process moving smoothly from the time he placed the order to the moment the battery was up and running. Even the city permits never turned into a headache, which made the experience feel unusually clean and organized for a home energy project.

2. Bruce K.
Yelp | Oct 9, 2025 |

Bruce ended up needing a warranty replacement for a faulty LG solar battery, and TSP handled the job with a speed and efficiency that stood out from the start. They turned around an estimate quickly for removing the old battery and installing the new one, and the price came in far below another quote he had already received. From there, the scheduling moved along promptly, and the crew finished the work fast, cleanly, and without leaving a mess behind. The one snag was timing: they showed up about an hour past the appointment window. Even so, their communication stayed first-rate, and the combination of a fair warranty estimate and tidy work left him comfortable calling them again.

3. Ben B.
Yelp | Sep 20, 2025 |

Ben came away from a solar install with TSP Solar that felt unusually straightforward from the first consultation to the final cleanup. On his home, the team took the time to answer a long list of questions without pressure or jargon, walking him through the savings, the equipment, and what actually made sense for his specific house. That clarity turned out to be the defining part of the experience: he felt confident at each step instead of pushed toward a sale. The installation crew kept that same level of care. They showed up on time, treated his property with respect, worked efficiently, and left everything spotless. The panels looked clean and finished, and they even got him set up on the monitoring app so he could watch the energy production in real time. After the system went live, his electric bill dropped noticeably, just as promised, and he was left with the extra satisfaction of knowing the setup was doing something good for the environment too.

1. Larry M.
Yelp | Jan 30, 2022 |

Larry had already bought his solar setup back in 2018, then moved to Texas and hit a wall when he tried to get help keeping it going. After getting nowhere with other companies, he found Solar Pros, and Mario and Javier got the system back up and running. He even set up monthly maintenance afterward so the equipment can keep working in the years ahead, which turned a stalled-out system into one that finally had a path forward.

2. Wilson L.
Yelp | Sep 20, 2025 |

Wilson came back to TSP for a second solar installation, and this time Mario’s crew took on more than just panels on a home in the middle of a remodel. They replaced the roof with careful precision and, just as importantly, dealt with a tricky electrical panel problem that other installers had refused to touch. What stood out most was that they were the only team willing and able to work through the complication, all while keeping pricing competitive, communication clear, and the timing flexible enough to fit the remodel schedule. He ended up with a crew that could handle both the roof and the solar side without turning the project into a headache.

3. Paul X.
Yelp | Aug 26, 2025 |

Paul X. had already spent more than six months fighting with the company that handled his panels after a faulty inverter shut the system down and his electric bills climbed by about $600 a month. He got stuck in endless back-and-forth, sending photos and hearing scripted explanations, even being told that a low bill somehow meant the panels were working — a claim that left him more frustrated than informed. By the time he reached TSP, he was ready to stop chasing answers. They quickly found the inverter problem, replaced it within days, and set him up with an app so he could finally watch the system’s output himself. They also pointed out a few broken roof tiles that were letting water through and offered to take care of that too. The part that stands out most is how he ended up with not just a working inverter, but a monitoring setup he had never even known existed, after months of feeling stuck in the dark.
