Solar Installation Group reviews

Sandy Hosier had a solar system installed on their home and, after 14 months of ownership, discovered it to be the best investment they’ve made so far. They singled out Benjamin Eagleton for his expertise and professionalism and repeatedly credited the installation crew for a smooth, well-executed process. What sticks with them most is the combination of knowledgeable staff and solid workmanship that turned the project into a straightforward, confidence-inspiring purchase.

Jessica Johnston had been weighing solar for months when she crossed paths with Deanna Greener. Deanna answered every question, explained options clearly, and left Jessica with a no-pressure quote that made the decision easy. The installation crews showed up on time, acted respectfully around the house, and wrapped up the job quickly. After two summers on a SIG Solar system, she ended up with exactly the performance promised — able to run the air conditioning without a big PG&E bill. She’s sent many friends and family to SIG because the combination of a calm, informative sales process and a system that actually tames summer cooling costs made the choice feel obvious.

Brandi had 62 panels installed a little over a year ago on a property with two homes, and the system was set up to provide power for both. The original install team arrived on time, worked professionally, and left everything tidy. After the first year she was hit with a higher-than-expected true-up bill and realized the system needed more capacity; even so, her total cost was still below what she paid PG&E the year before. She reached out to Josh Clark to explore options, and he arranged for 18 additional panels to be added. Josh responded promptly, walked her through the choices, and took the time to answer every question, and the crew that installed the extra panels was likewise friendly and professional. She ended up with 80 panels feeding both homes, and the extra capacity helped address the true-up issue. The detail that stood out most was Josh’s hands-on responsiveness and clear explanations — Brandi recommends asking for him as your representative.

Jacob M wanted extra panels to handle charging his electric vehicle and already trusted SIG after a system they installed about three years earlier. When his original rep had moved on, he was referred to Josh Clark, who welcomed him, listened closely to the EV needs, and scheduled a sit-down to map out options. Josh’s friendly, personable approach made planning straightforward, and he flagged a few small issues from the prior install so the crew would take care of them during the new work. Josh kept Jacob updated at every step, and the project finished with additional panels that meet the EV charging goal and the previous issues corrected. The detail that stands out is that Josh not only designed the expansion but made sure the crew fixed the earlier problems on install day—something Jacob appreciated.

Darci worked with SIG to install solar and appreciated how Deanna guided her through every step, patiently answering what felt like a million questions. She leaned on Deanna from the initial conversations to project completion, and even a year later still texts with follow-ups — Deanna typically replies almost instantly. Because of that clear guidance and ongoing availability, she recommends SIG to others. The detail that stuck with her was having a single, responsive point of contact who kept answering questions well after the job was finished.

Damin Corona decided to expand his system and ended up with a full upgrade: 23 solar panels, one battery, an inverter and a smart electrical panel mounted on his house. A coworker, Tony, put him in contact with Josh Clark, and he worked with Josh through a low-pressure, informative process—Josh answered every question and tracked down any details he didn’t have. The crew arrived at 8 a.m. on a Thursday and completed the entire installation that same day. Damin wasn’t home for the work, but his wife stayed and watched the team be respectful and professional. The crew finished the job completely and cleaned up thoroughly—no boxes, trash, nails or screws left behind. He made one specific request up front: no visible conduit on the roof or exterior, and Josh’s response was “no problem,” which the team delivered. What stuck with him most was that request being honored alongside a spotless, same-day install with zero follow-up issues.

When Jacob decided to move his house to solar, he partnered with Rylan from SIG Solar and found the whole process unusually calm and clear. Rylan guided him through every step, patiently answering questions and breaking down the timeline and technical details until Jacob felt confident about the choices. What set the experience apart was Rylan’s attention to detail and obvious pride in the workmanship — he double-checked elements, prioritized quality, and kept the install orderly rather than rushing to finish. The result was a smooth, efficient transition with minimal stress. The one thing Jacob keeps telling friends about is asking for Rylan: his patient explanations and focus on doing the job right are what made the difference.

Sam Lorigo, a first-time homeowner facing the big decision to go solar, found the entire process top notch from start to finish. He leaned on Josh Clark, who went above and beyond at every step—making him feel comfortable, answering every question honestly, and staying reachable throughout. He discovered that SIG’s office team and the installers kept communication clear and polite, and everyone involved stayed friendly and professional during the install. What stood out most was Josh’s nonstop availability—always answering texts and calls no matter how busy—which took a lot of the stress away. In the end he walked away very happy with the system and the support, and he urges anyone with doubts about solar to contact Josh at SIG Solar.

Rich had Sig Solar install a rooftop solar system two years ago for a home that runs a pool and spa. After the first year he discovered a true-up bill of $1,025 and the second year it dropped only to $925. He expected the installer to size the array correctly—Sig Solar had reviewed a full year of his PG&E bills before the install—but they undercounted how many panels were needed to cover his usage, especially the pool and spa load. When he pushed back, the company’s answer was essentially that the only fix was to buy more panels. He ended up paying recurring true-up charges and feeling stuck with the extra expense and the recommendation to expand the system.
