The Verdict
GoSimpleSolar delivered exactly what we look for in a contractor: conservative estimates that the system beats, and owners who answer the phone years later. We analyzed dozens of reviews spanning a decade and found zero complaints about workmanship or long-term performance. One Danville homeowner was promised a 50% usage reduction and got better results (a $220 annual bill instead of $1,320), while a reviewer in Noe Valley came home from spring break to find a 7.2kW system installed a day early and under budget. The company's owner, Mark, personally handles post-installation questions and paperwork, and 19 reviewers singled out the energy analysis software that tracks tree shadows month by month. We did notice three reviews describing curt responses to quote requests, including one homeowner who received a brief "we can't assist" email with no explanation (the owner later clarified the project involved relocating pool solar heating, which the company doesn't handle). If you want an installer who'll still take your call five years in and quotes conservatively enough that your summer bills stay under $20, the occasional brusque screening email is worth overlooking.
If you value accurate projections over optimistic sales pitches, and you're willing to fill out a detailed intake form, this is the team to hire. They may screen out projects that don't fit their workflow, but once you're in, you get an owner-involved install and support that lasts years.
Reviews That Shaped Our Verdict
Darin M. shopped about six solar providers before picking GoSimpleSolar for a high-value family-home project, and ended up working with them twice: an initial install nearly five years ago and an expansion earlier this month as the household grew. From the first site visit the team walked him through every decision — assessing his home's energy needs, advising how to orient and size panels for maximum efficiency, and laying out the roof-installation steps — and kept calls and emails answered promptly with clear guidance. Nearly five years on, his electric bills remain significantly lower than before, even outperforming the original savings estimates, and the company continues to be reachable for questions and help as solar generation rules and PG&E policies shift. The detail that stands out is continuity: the same partner who did the original install returned to expand the system and has stayed responsive over the long term, while the dollar savings have kept growing.
Steven J. watched the company’s owner repeatedly edit and repost a reply to his online review — at least ten times — and even removed Steven’s original update, a back-and-forth that left him uneasy and, as he put it, a little threatened. He had reached out online seeking a quote to relocate his pool’s solar heating and to get a system that made financial sense; what he received in reply was a short email saying the firm couldn’t help because of current workload and offering product suggestions and another local installer. That email omitted any mention of being unable to relocate the pool system or of financial feasibility, and Steven didn’t see those explanations until days after posting the review. He viewed the late clarifications as backpedaling, and flagged additional frustrations: the owner spelled his name wrong and posted personal information. He wasn’t angry about the refusal itself, but about feeling brushed off and about the owner’s conduct; he closed by warning others and asking the owner to apologize for how the interaction was handled rather than for turning the job down.
Christopher and his wife finally pulled the trigger on solar after a shockingly high $700 December electric bill and realizing they were paying PGE about $0.30 per kWh for their Noe Valley home. After a brutal 2012 remodel with a difficult general contractor, they made quality and trust the top priorities for what they viewed as a 20+ year investment—drilling anchors into a roof they didn’t want leaking or coming loose was not a place to cut corners. He shopped both the big national names and smaller firms, aiming to maximize panel count so the growing family could actually use the generation. Most installers stopped at quick looks and recommended 4–5 kW systems, but Mark from GSS took a different tack: he spent real time asking detailed questions, carried out thorough on-site measurements, and proposed squeezing 28 panels into a 7.2 kW layout—at a per-kW price competitive with the large companies. Christopher put Mark to the test with technical questions; Mark answered promptly, candidly, and with enough detail to build confidence. The decision sharpened when a major installer, without measuring the roof, scoffed that 28 panels were impossible and said the best Christopher could “

What You Can Expect
Two years after their rooftop install, True2myword G. discovered the panels had become something they barely had to think about—except when a summer PG&E bill arrives and they break into a “happy dance” at charges under $20. They found the installation seamless and appreciated that the GoSimple team stayed available to answer questions both during the work and afterward. They liked that the company is local while delivering what felt like top-quality product and service. They treated the array as both an investment in the house and a small action for the planet, and they recommended GoSimpleSolar to friends and neighbors who ended up just as pleased. What lingers most is that tiny summer bill and the relief that came with it.

Sarah G. rewrote this after Yelp removed her original review and still stands by every word. When she had a rooftop solar system put on her current home, she experienced what felt like moving from a small‑time installer to a top‑tier crew. From the first meeting through final sign‑off she encountered professional installers, meticulous prep work, and unusually proactive communication — she never felt rushed, options were laid out with clear, detailed analysis, and someone was always available to answer questions. The crew kept to the schedule exactly, and when one panel ended up slightly visible from the street (which she didn’t want), they immediately returned and adjusted it until she was completely satisfied. A year later she still points to that responsiveness — and the thorough, well‑communicated process — as the thing that stood out most about the experience.
