Golden State Solar reviews

The Verdict
We recommend Golden State Solar without reservation. In 35 reviews praising workmanship, we couldn't find a single complaint about installation quality or shortcuts. One homeowner watched Tim coordinate with their roofer to replace a 100-amp panel during a solar install for just the cost of materials and permits, a job that normally runs $2,500. Reviews show 33 mentions of project management discipline: Tim showed up daily during construction, posted permits within three days of signing, and turned one system on just 16 days after the initial meeting. When other installers told a homeowner they couldn't integrate new panels with a builder-grade starter system, Tim added panels and a battery in a few days, then came back twice to replace a faulty microinverter and panel until output matched projections. That follow-through showed up in 19 reviews about post-sale support. The only quirk we noticed: Tim apparently inspired enough loyalty that one customer's dog ate his work gloves, and he didn't mind.
If you want the cheapest quote in your inbox, keep shopping. But if you want an installer who'll size your system to your actual PG&E bills, show up on your roof twice after install to verify performance, and swap out parts until the monitoring app shows what you paid for, Golden State Solar is worth the call.
Reviews That Shaped Our Verdict
Lucy moved into a new-build home that came with only the bare-minimum solar preinstalled, and within a few days Tim, Nick and their crew integrated new panels and added a battery to that existing setup when other companies had declined. She found the whole process — from consultation to installation — quick and straightforward. Shortly after the install one panel showed offline; the team promptly swapped the microinverter, and when performance still lagged they returned to replace the panel itself until the array behaved properly. More recently an app flagged a microinverter error and Tim replied within a day to sort it out. What lingered for her was not just the fast turnaround but the willingness to tackle a nonstandard setup and to keep coming back until everything worked right.
Eric K. had installed a home solar system with a backup battery through a different contractor and endured at least nine return visits while the system never worked right. The original crew — Green Wolf Energy — eventually gave up, refused to honor a warranty, and left him stuck. Referred by SolarEdge, he contacted Golden State Solar and met Tim, who immediately stood out for two things: punctual, clear communication and the ability to actually fix the problem. Tim confirmed appointments the night before, called when parts arrived, arrived on time with the right tools, and laid out exactly what needed doing and what it would cost. He diagnosed a burnt inverter, corrected a lot of incorrect wiring between the battery and the main breakers, and properly programmed the battery’s usage. Even while Eric kept a safe distance and wore a mask, Tim welcomed questions and explained each step as he worked. What stuck with him was that after so many failed visits from the original installer, one well-organized, communicative visit from Tim restored the system — new parts in hand, wiring corrected, and the battery finally set up to behave as intended.
Christine was hunting for a reliable solar installer after watching several companies fold and feeling squeezed by rising PG&E rates. She found Tim at Golden State Solar, a decade-old shop with solid CSLB standing, and ended up with a high-efficiency Solaria system using SolarEdge optimizers and an inverter — a configuration Tim walked her through alongside several other options, laying out pros and cons and sizing everything from their historical PG&E usage. Rather than push a single brand or a one-size solution, he tailored the design and recommended a package that gave a projected break-even of about six years. When a tiny 100-amp main panel threatened the installation, Tim swapped it for a 200-amp panel for the cost of materials and permit — $750 — a move that saved Christine what she expected would have been $2,500–$3,000. Tim’s crew stayed in-house with a journeyman electrician (no subcontractors), and Tim showed up every day to oversee work, answered texts and calls promptly, and even returned twice after completion to check details. He also handled monitoring setup in person, stayed to explain breakers and shutoffs, and flipped the system live on a Saturday after PG&E’s

What You Can Expect
Mark has had a rooftop solar system for more than a year and remains genuinely pleased with both its performance and how the installation went. He found Tim’s attention to detail unmatched — Tim guided him through every stage, ensured top-quality equipment was used, and handled the finer points other crews might miss. Golden State Solar coordinated closely with his roofer, and Mark traced the project’s smooth, on-time finish to that teamwork. The most memorable part of the experience was Tim’s hands-on management combined with seamless roofer coordination, which kept the whole job trouble-free.
Mark S has lived with his solar system for more than a year and remains delighted. He found the company's project lead, ***, remarkably meticulous — guiding him through every step and catching details others might miss. He appreciated that Golden State Solar used top-quality components, and he relied on the team's coordination with his roofer to keep the job moving smoothly. The result: a seamless installation that completed without delays and continues to perform well after a year.
Megan discovered Tim at TD Construction several years ago and has kept bringing him back for jobs around her home. She watched him rescue a mismatched chandelier by reworking it so seamlessly that you couldn’t tell it had been altered — she kept the light instead of returning it. He then installed a solar well pump, completing the work neatly and on schedule. She ended up with a contractor who combines expert woodworking and solid electrical skills, shows up when he says he will, and charges what she considers reasonable and fair. He made the process easy (even when her dog chewed his work gloves), and the lasting image for her is a craftsman who can both save a beloved fixture and wire a dependable solar pump without fuss.
