Solar Installation Group does the basics well. We found 153 reviews praising their workmanship, meaning your roof attachments and wiring will be clean and code-compliant. One homeowner had a general contractor ghost them after an inverter died, then watched SIG step in and replace it for a reasonable fee even though they hadn't been the original hiring party. That's the company in a nutshell: reliable when things go sideways, but not one you'd choose for cutting-edge support or killer pricing. The installers finish most jobs in a single day and leave no mess behind, which 215 reviewers appreciated. What sets them apart is the sales team. Josh Clark, Damian Fernandez, and a few others get called out by name in over 160 reviews for patient education and zero-pressure consults. One couple specifically chose SIG after another installer made them feel uneasy, and they ended up getting three design options instead of one take-it-or-leave-it pitch. The flip side: post-sale support scores lower than workmanship, and 22 reviews mention communication gaps after the system goes live. If you need hand-holding through your first utility true-up or want proactive monitoring check-ins, you may be disappointed. (One reviewer didn't notice their inverter had died for several weeks, which suggests the monitoring app isn't exactly pushy with alerts.) But if you value a respectful sales process and skilled installers who won't leave conduit dangling off your eaves, SIG is a safe bet.
If you're comparison-shopping purely on post-install support or app features, look at companies with higher service scores. But if you want an installer who'll replace a failed inverter even when you weren't their original customer, and a sales rep who answers texts a year after signing, SIG is worth the call.
John Y. had SIG work on his solar system back in 2019, but the install went through a general contractor so SIG was a subcontractor — a setup he later discovered added unnecessary cost. A few months ago the inverter died (it took him a few weeks to notice), and the general contractor promptly ghosted him, so he called SIG directly. Ashley and Hasten stood out for being especially helpful, and the rest of SIG’s staff treated him well. They fitted him in and installed a new inverter today for a very reasonable price; the original unit was still under parts warranty, but labor wasn’t covered. The repair process stretched out a bit, which he understood — he realized contractors can’t pause large jobs for low-margin warranty work — so he appreciated that SIG agreed to handle a system for which they technically weren’t the paying customer in 2019. The detail that left the biggest impression: SIG was willing to help a non-customer and charge a fair labor rate, so next time he plans to hire them directly to avoid the middleman markup.
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.
Irene C. rarely writes reviews, but after a recent home solar installation she felt compelled to share how refreshingly different the process was. Expecting another high-pressure pitch after two poor visits from other companies, she instead experienced punctuality and professionalism from the first contact: Damian Fernández called ahead, arrived exactly when he said he would, and immediately put them at ease. He patiently walked them through three distinct system options — not just one — explaining each in plain language so they could "make an educated decision" for their family’s energy needs. Damian kept them informed at every step by phone or text; what he had estimated as a 3–4 month timeline ended up completing the project in under two months. The install crew matched that reliability: they arrived on schedule, worked quickly and carefully, completed the full install in a single day, and left the property spotless. Her clearest takeaway: ask for Damian Fernández — he shows up on time, explains real choices, and coordinates a fast, clean install that arrived well ahead of schedule.

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.
