The Verdict
Ambrose Solar earned our top recommendation after we analyzed hundreds of reviews and found the kind of consistency most installers can't deliver. One homeowner returned to Ambrose for a second project after their first install in 2021 moved like clockwork, even when it required swapping out an entire electrical panel. Another watched a competing company miss every deadline on a 2005 system upgrade, then called Ambrose, who finished the job on time with what the customer called "a high level of precision." We found 335 mentions of workmanship quality and zero complaints about shoddy roof attachments or wiring. The company routinely handles complex projects (battery add-ons, panel expansions, EV charger installs) without dropping the ball. One homeowner hired Ambrose to install a Powerwall, then watched their original installer, SunRun, stonewall them for two months over a warranty claim on defective panels. Ambrose stepped in, worked directly with the manufacturer, and secured replacement panels in a day. If you want an installer who'll still pick up the phone three years later when your monitoring box stops talking to the grid, Ambrose is worth the premium.
If you want the absolute lowest quote, keep shopping. But if you want a local team that will troubleshoot a surge-damaged inverter at no charge and chase down your utility rebate paperwork until it clears, Ambrose is the right call.
3 Stories That Stood Out
Ralph began the project wanting to replace a tired solar array installed in 2005 and initially had Ambrose Solar bid the upgrade. Ambrose came in a close second, so he tried a different contractor that promised faster completion. When that firm missed deadlines and expectations, he went back to Ambrose — and the difference was immediate. Ambrose stepped in responsive and organized. Their crew walked him through the estimates, the technical specifications, and each step of the install, answering every question with clear, confident explanations. They completed the work on schedule and with precise workmanship, leaving no loose ends. What made the experience stand out was their honesty and attention to detail: after a disappointing start with another company, Ambrose not only delivered a properly modernized system but also rebuilt the homeowner’s confidence by explaining how everything would perform and why they chose each component. The lasting image: a finished, up-to-date system and a homeowner who finally understood exactly what he had and how it would work.
dgx unreal had a SunRun solar array on their home, and about two years later brought Ambrose Solar in to add a Tesla Powerwall. The Powerwall installation went smoothly—clear communication, efficient work, and a crew that knew exactly what they were doing. While Andrew Gates from Ambrose was checking the integrated system, he noticed it wasn’t producing as expected. They troubleshot together and discovered two Jinko panels were underperforming on a system about 3.5 years old. Expecting the original installer to handle the warranty, they reached back out to SunRun—and encountered two months of delays: missed calls, slow responses, and an excuse that someone couldn’t process an Excel warranty form, which effectively stalled the replacement. Even after the homeowner completed the paperwork, SunRun declared the panels fine and refused replacement, despite Jinko already approving a free warranty swap. Frustrated, they went back to Ambrose; Andrew and the Ambrose team dealt directly with Jinko and, within a day, had the warranty cleared and replacement panels secured for shipment. The standout detail was Andrew’s ownership of the problem—Ambrose moved the claim through and got parts on a
Jason Coleman reached out to thank the team after a nearly flawless solar installation at his home — inspections are still pending, but the on-site work wrapped without the usual headaches he'd experienced with other companies. He had come in worried about specific items like trenching next to existing lines and reinforcing the pumphouse walls; the crew handled each concern methodically and left nothing to chance. What set this job apart for him was the crew’s attention to detail and cleanup: trenches were backfilled and tidied so well the ground looked untouched, conduit was painted, and work areas were swept and orderly when they left. He singled out foreman Dalton Chute for consistently courteous, patient, and thorough oversight — Dalton knew exactly what needed to be done and didn’t take shortcuts — and thanked the rest of the crew by name: Jeffy Hernandez, Lalo Ortiz, Omar Arriola, Diego Solorio, Bryan Becera, Irvin Gaytan, Jesus Sanchez, Guillermo Castaneda, and Ivan Salazar. He gave the company a five-star rating, and the lasting image he’d share with a neighbor is simple: spotless cleanup and steady, professional leadership on the roof and in the trenches.

What You Can Expect
Joylani ended up with a 37-panel solar setup paired with two Tesla batteries on her Vacaville home, and the standout part of the experience was how tailored it felt from the start. Jon Landsman took time to teach them the differences, answer every question, and shape the system around what they actually wanted instead of steering them toward a cookie-cutter package. From design through installation, the work moved smoothly, with a crew that stayed efficient, courteous, and professional, while the pricing and financing came in as a strong fit. What made the biggest impression was the follow-through: even a year later, Ambrose Solar was still checking in to make sure everything was running properly and performing at its best.
Janna spent more than five years researching solar companies before finally choosing Ambrose Solar for her home, and the part that stood out most was how the team kept showing up after the install was finished. The crew worked respectfully and kept the site clean, while Pat Ambrose personally reached out to make sure she knew about PG&E battery rebates. The paperwork side felt a little confusing at first, but Stephanie Reiser, her project lead, stayed patient and guided her through the whole process. That extra attention paid off in a big way when she unexpectedly got a $4,500 credit back, a detail that likely made the long wait for the right installer feel worth it.
Jeffrey ended up with a 20-panel system installed by Ambrose Solar about 18 months ago on his home, and it has run flawlessly ever since. What made the experience stand out was not just the installation itself, but the way the company stayed with him through a messy rebate fight that stretched long after the panels were on the roof. He worked with Mark on the estimate, Vincent and Austin as project managers, and a hard-working installation crew that left a strong impression for being both friendly and efficient. The real hero of the story was Stephanie Reiser, who kept pushing on his PG&E SGIP rebate when the paperwork got tangled up by a SunPower-to-SunStrong ownership transfer that confused the utility after the job was finished. She stayed on the issue from before the installation all the way until the rebate was finally approved, handling at least 50 emails back and forth with the various parties while keeping Jeffrey updated along the way. As a retired mechanical engineer, he came away especially impressed by that persistence and attention to detail.
E kept coming back to Ambrose for a reason: they put solar on two different houses, and the second project added an energy storage system and an EV charger. What stood out most was how consistently the company delivered on the numbers. Over six years across both homes, the production estimates lined up closely with actual performance, while other bids had promised more than reality could support. The installs themselves were tidy, with minimal exterior conduit, and the systems came online quickly using top-quality equipment that has performed just as expected. Behind the scenes, the office team, including Vincent and Stephanie, kept everything organized, and the technicians were friendly enough to go the extra mile — Jo got a special shoutout. He also ended up sending friends and neighbors their way, and those households had similarly good experiences.
David R. contacted Ambrose Solar after the contractor who installed his panels in 2019 referred them. He needed a battery to protect his home from power outages and reached out to have one added to the existing system. The installation surprised him — the crew turned up focused on craftsmanship at a time when he’d noticed quality slipping elsewhere. The battery and whole system are working beautifully, and Ambrose provided steady, helpful support throughout. What stayed with him was the solid workmanship and follow-through that actually delivered reliable backup power.
Annie hired Ambrose to put a solar array and backup battery on her home last year, and for the past 1.5 years the system has run reliably. From the initial assessment to the on‑roof installation and the final PG&E inspection, Ambrose managed the project with a consistently professional team who answered questions by phone whenever they came up. They also handled the paperwork for PG&E’s SGIP incentive program: Stephanie Reiser patiently guided her through the steps, submitted the required documents on her behalf, and about a year later the PG&E check arrived. The detail that stood out was Ambrose’s end‑to‑end handling of the incentive — not just the hardware and install, but the follow‑through that produced the SGIP payout.
Denise had spent two frustrating years wrestling with her original solar provider before Ambrose stepped in and turned things around. Justin and Jo became the steady hands she needed, helping keep her system running and getting her properly signed up and connected to the monitoring software so she could finally track her solar production. What stood out was not just the repair work, but the relief of having two people who could untangle the mess and make the system usable again.
Annie H. hired Ambrose last year to put solar panels and a backup battery on her ranch-style home, and the system has been performing well for the past 1.5 years. She experienced professional service from the initial assessment through installation and the final PG&E inspection, with staff who were easy to reach by phone whenever questions came up. The standout detail was Ambrose’s help with PG&E’s SGIP incentive: Stephanie Reiser patiently guided her through the process, handled the paperwork, and submitted the necessary documents on her behalf. About a year later they received the check from PG&E — proof that Ambrose stayed involved after installation, not just during it.
About a year ago John Saavedra and his wife, after comparing several solar companies, chose Ambrose Solar for a rooftop system of 20 REC panels paired with a single Tesla Powerwall 3. He found the whole team—from Kelsey Commerford in sales to the technical crew, installers, and the after-installation staff—professional, knowledgeable and responsive. Kelsey helped dial in the right system for their needs, and Staphanie Reiser took charge of the utility coordination, filing the rebate paperwork and making sure reimbursements actually arrived. The equipment has performed reliably, carries a 10-year warranty, and has already produced a noticeable drop in their PG&E bill, especially during long sunny summer days. The detail that stood out most was the end-to-end handling of rebates: concrete paperwork and reimbursement, not just promises, alongside tangible savings on monthly bills.
