    Semper Solaris did a fantastic job installing my Tesla Powerwalls!…read moreWhen I had a glitch with them recently, I was lucky enough to be connected to one of their techs, Linda C.! Linda walked me through the steps to get my glitch fixed. She also explained to me exactly how the system works; pulling energy from our solar, the Powerwalls and the grid. I now feel confident in navigating the app and understanding the data! Linda is very knowledgeable, friendly and helpful. I truly appreciate her expertise. Please extend my sincere thanks to her, especially for making it easy for me to understand the data!

    I started with a call to Semper Solaris to inquire about installation of a couple of additional…read moresolar panels. Robert C. came to my home and went over the advantages of adding a few more panels that would still keep me in tier 1 status with the power company as well as consideration of adding a Powerwall III battery. Considering the increased power generating capacity of newer panels and storage capability of the Tesla battery, I was sold by the quality and value of the expanded system. The design and contract review was done online in a timely fashion and it was a swift transition to installation taking place in just one day, as the the lead installer (Antonio) was joined with two co-workers who explained how the project would move forward and answered all my questions. The work was complete by 3pm and I was extremely satisfied with the entire process. Thank you Semper Solaris for a quality job for a fellow veteran. Dan

    I can't say enough good things about Carlos Gomez from Sunlight Electri-Cal Solutions…read more I've been working on a non-standard solar setup using an EcoFlow Delta Pro Ultra X and EcoFlow Smart Home Panel 3, and finding a contractor who truly understood this type of system was incredibly difficult. I spoke with many contractors, and almost all of them sent salespeople who gave generic answers or tried to push cookie-cutter solutions that clearly didn't fit my setup. Carlos was completely different. From the moment he arrived, it was clear he wasn't a salesperson -- he's an engineer, and it shows. He took the time to deeply understand my system, reviewed actual spec sheets on the spot, and immediately identified issues that other contractors completely missed. Multiple companies told me Hyundai panels would work fine. Carlos checked the amperage limits, applied proper safety margin calculations, and clearly explained why those panels would not work with my EcoFlow system -- saving me from a costly mistake. He also walked me through: Proper panel selection within voltage and amperage limits Safe string configurations and series wiring How to maximize roof space while staying within code Permitting requirements I hadn't been told about before On top of that, Carlos identified critical code and safety requirements that no one else mentioned: Bollards required in the garage to protect battery units Correct battery placement to maintain required clearance from doors and entrances Heat detector requirements for battery installations in a garage These are all things that would have caused inspection failures later -- and Carlos caught them immediately. He spent well over an hour with me, climbed onto my roof to check for obstructions, inspected battery placement, reviewed wiring paths, and answered every question in detail without ever rushing me. What truly sealed the deal was how efficient and transparent the pricing process was. Carlos was able to turn around a detailed quote very quickly, and when I received it, I was honestly surprised -- it was a significant amount lower than every other quote I received, even though his evaluation was by far the most thorough. Given everything: His technical expertise The level of detail and care The ability to integrate with my existing system The fast turnaround And the much better pricing Choosing Sunlight Electri-Cal Solutions was a complete no-brainer. Carlos is knowledgeable, meticulous, honest, and genuinely passionate about doing things the right way. After meeting him, I completely understand why this company has such strong Yelp reviews. If you're in the Bay Area and need electrical or solar work done the right way, especially for a non-standard or custom system, I highly recommend Carlos and the team at Sunlight Electri-Cal Solutions.

    I actually first contacted Sunlight Electri-Cal very early on this year, in April. I had closed on…read morea new home but knew we would want to get solar installed. Juan was very responsive and came out to take a look at our home right away. What I loved about Juan and his team is they are NOT sales people, they're real engineers who are focused on solving your problems and meeting your needs. Juan and his team are true solar experts and know exactly what they are doing - they were great at walking me through key details I should know about the system, how to best take advantage of having a solar system, and did their best to get me scheduled (in spite of multiple difficulties) for installation before the end of the year. Just for context, I've talked to another solar company where clearly they were just about trying to close the deal and sell sell sell, which really turned me off - it felt like they just wanted our money as opposed to wanting to understand what we really needed. Juan's team really shined here by just showing up to be real experts who are thoughtful about what system you need, as opposed to trying to close a deal. Juan and his team were also really patient and flexible. Our new home's solar system had to be turned on before we could start any work, and that process took months due to Sunnova going bankrupt. And, they were also really thoughtful when we mentioned we had added in some upgrades that would affect electricity use (ie saunas and outdoor electric heaters), and they reassessed their initial project and updated it to accommodate that. I thoroughly enjoyed working with them and am really grateful that we got our project done so well!!

    These guys handled the installation of the panel and conduit to my Tesla powerwall. The images say…read moreall that needs to be said about the quality of their work. They lied to me when they said running the conduit through the attic would be impossible (as originally planned) on the day of installation. They said they will have to wrap it around the outside of the house and not to worry about it because it'll be hardly noticeable. I took their word for it, but figured they would have at least done a professional job and ran the conduit along the roof instead of in plain sight. They didn't even attempt to install it correctly. What's worse is that they stand by their work. I've been dealing with Tesla support to resolve this matter and these guys decided to go silent. It's been 4 months since I originally filed the complaint, right after it was installed, requesting that they install it properly. If you consider hiring them for your solar/powerwall installation needs, just know that they stand by their work highlighted in these photos. Needless to say, they like to cut corners. Speaking of cutting corners, I highly advise that if for whatever reason you decide to work with them, that you hire an independent electrician to audit their work. They effectively derated my system by putting everything behind a 90 amp breaker, even though in the permit (which I had to fetch myself from the city) it clearly stated there was to be no main rerate. You can't trust the city/county inspectors, because they say it and passed it. No one advised me that they derated my system.

    The service before and including the install was perfect. Then they completely abandoned me. I…read morestarted in April, it's now June over 100 degrees and they cannot even tell me when it will work. Two neighbors of mine went with Sunrun and are up and enjoying savings and great service. Not me, they don't even give me updates. I cannot stress enough how amazing the start was, I even bought a couple hundred shares of their stock I was so impressed. I've lost thousands and now I see why.
