Tesla Solar Battery Install
We had a solar battery installed on our new home by Ambrose and had a great experience from beginning to end. Their team was professional, communicative, and had great follow up to ensure we were getting max impact from our system. We got a few quotes but appreciated the great reputation and all that Ambrose offered. We highly recommend working with them if you have a solar project!

Perfect Experience!
Ambrose Solar installed our 20-panel system about 18 months ago. It has worked perfectly the entire time. Every person with whom we worked was friendly and professional, ranging from the estimator (Mark), the project managers (Vincent and Austin), the installers (a very friendly and hard-working crew whose names I cannot remember), and finally to the great Stephanie Reiser, who was indefatigable in pursuing my rebate from PG&E SGIP program. The rebate was a problem because the equipment and solar lease were originally from SunPower, which was acquired by SunStrong, shortly after the installation was completed. The transfer of ownership was confusing to PG&E, who were administering the rebate program. Stephanie corresponded with all parties from before the installation, until just recently, when the rebate was finally approved. All in all, she must have written and responded to at least 50 emails on the subject, all the while keeping me informed of the progress. As a professional mechanical engineer (retired), I highly recommend Ambrose Solar and its excellent staff.

Go with Ambrose!
I would like to write a quick review of my experience with Ambrose solar... I think my decision to finally put solar on my roof took more than a year to make and every step of the way from Kelsey who was my sales person to Vincent my project manager and Mike my closing meeting specialist was a seamlessly professional experience. My project was made difficult by a few complications with my house not the least of which was the need for a new roof and a solution for not having a 200 amp feed from PG&E into my house. Those guiding my experience at Ambrose were beyond patient, as I asked them to explain things over and over again. When it came to the actual installation, I was completely blown away by the crew that Ambrose sent... to call them. Professional was a complete understatement. Imanol led the crew on the roof and just got the job done so fast! Tony dropped what he was doing every single time I asked him a question and explained things to me so clearly! Nate did the same thing while he was installing the Span panel. What was clear the entire time was that all representatives of Ambrose solar understood what a big decision. This was for me and my family. They took it seriously and helped me, a complete Luddite gain an understanding of what was ultimately a pretty complex project.

Smooth service, great results
Paul Karst and everyone at Ambrose Solar made everything so easy. Paul is highly knowledgeable about all aspects of the solar industry. He and his team were easy to reach, answered all my questions and concerns. The process and results all went smoothly.

Great Experience
Worked with Paul and the team to install solar panels on our recently purchased home back in 2020. After doing a lot of research, I knew I was getting a good product (SunPower panels), with reasonable financing options, and the work would be done by a reputable company in Ambrose Solar. Almost 5 years in, I have no complaints. We produce more power than we consume, with room for new electric vehicle or hot tub if we wanted. They also have a nice referral program if you know anyone in need of solar.

Ambrose Solar
I’ve had my system for 2 yr. Installation was done timely. No problems. Ambrose took care of permits. Very responsive to calls. System has worked well and exceeded expectations w/r to energy savings! Had a problem with a connection after a year. Ambrose fixed it at no cost. Highly recommend!

Thrilled with solar system from Ambrose
Absolutely thrilled with my solar system from Ambrose – 4 years later and still going strong! From start to finish, the installation process was seamless. Planning, permits, inspection, and PTO all went off without a hitch – no surprises, no delays. The team at Ambrose was professional, communicative, and clearly knew what they were doing. Four years in, I’m still seeing the benefits. My system was sized perfectly, and I actually end up with a small annual true-up credit. Even better, I’ve been completely insulated from PG&E’s constant rate hikes – my energy costs are stable and predictable. One of the best decisions I made was including a battery. I live in an area heavily impacted by PG&E’s Enhanced Powerline Safety Settings (EPSS), which has already triggered nine power outages this year alone. Thanks to the battery backup, I barely notice. My lights stay on, my fridge keeps running, and I’ve even been able to share my Wi-Fi with a neighbor so they can keep working during blackouts. Neighbors constantly ask how I’m managing to stay powered through these outages, and I always point them to Ambrose. I genuinely can’t say enough good things about the system or the company. If you’re considering solar, this is the team to go with. One of the best home decisions I’ve ever made.

When it comes to the solar panel field, this is the best when it comes to experience. First of all in dealing with people, they don't have any so called gimmicks to hook you, meaning straight forward, try it they will not let you down.

Still Very Happy with Ambrose Solar
As always, our experience with Ambrose Solar was amazing. I called them to ask why our consumption differed vastly from what PG&E was reporting. We didn’t know if it was an app problem or meter problem or what! Justin took the time to research all possibilities and figured out what the issue was. Their technician Arnulfo came out and quickly resolved the issue and now our consumption very closely aligns with what PG&E says we’re consuming. Both gentlemen are very patient and friendly and professional. We are still very satisfied with Ambrose Solar and would recommend them!
