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

Semper was very professional and gave us a reasonable price and guidance for tax credits at that time.

Ken from Semper Solaris came over and we considered all the options and we received some credits for our loyalty.

Their pricing was the best of the three contractors we considered, and they were also the only company willing to set up a non-export system so we could preserve our NEM 2.0 status and still get permission to operate from PG&E. That was a huge advantage for us, since other contractors were pushing us toward NEM 3.0. Their sales team was patient, helpful, and not pushy at all. They walked us through our options clearly, were honest about scheduling constraints, and still found a way to get us in on a pretty good timeline. They also came up with creative solutions when other issues popped up, which we really appreciated. We're very happy so far with our 14 additional panels and Tesla Powerwall 3. Rob, Brad, and Josh were all great to work with. They're highly rated for a reason.

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've had a great solar power installation experience with Simply Solar. SS's customer rep, David…read moreFrank, patiently answered a million questions in easy-to-understand terms. He found many savings and benefit enhancements along the way. In spite of the solar credit expiring at the end of 2025, David put together an HDM plan far superior to anything I found when getting competing quotes. It simply lowered the cost without complicating ownership or savings or adding any ongoing cost. Speaking of competing quotes, they beat everyone else. All together, I saved about $20,000 without undue complication. Production Manager Jack kept me fully informed along the way. He always responded promptly and clearly to every query. He scheduled and completed the solar installation much earlier than promised. The installers also travelled a long distance outside of their service area to do the job in the Sierra foothills. So, even if you think your home is outside of their service area as shown on Yelp, you might give them a call and see if they can do it. Installer Gio and his team were excellent. Our panels were going on a tile roof and I had concerns about the L brackets pulling up the tiles as they slide under the downhill side of tiles. They ground channels into each of the affected tiles for these brackets so that the roof is still as water tight as a duck's a**. Gio, the electrician and main contact on site was both smart, friendly and patient in explaining the details while the solar panels, Tesla PowerWall batteries and solar inverter were installed. I'm now using Tesla's app to monitor the whole system, which is working perfectly and is fascinating. I couldn't be happier. Thank you, Simply Solar!

DO NOT DO BUSINESS WITH THEM. This company operates in bad faith and will bait-and-switch you. I…read moreWILL BE REPORTING THEM TO BETTER BUSINESS BUREAU TODAY. We originally chose them a few years ago because they offered free solar panel removal and reinstallation when we eventually needed a roof replacement. The initial install went fine, but trying to get them to honor their contract now has been a nightmare. Bait and Switch: They are suddenly demanding a $3,600 fee for the removal. Even their salesperson admitted this fee was not indicated in our main agreement from 2021, but is now picking apart vague fine print (outside of our contract) to justify it. We have sent the contract over multiple times and asked them to highlight the language where it specifies this charge. Unethical leadership: Leadership is aware of this $3,600 gap, but they don't want to back down. Terrible Customer Service: They are dragging their feet and refusing to coordinate with our roofer, who has been consistently asking for dates to remove the solar. Ignored Emergencies: We explicitly told them we have an active roof leak and asked them to prioritize the removal so we could fix our home. They did not care. Once they finish your initial install, they will abandon you and refuse to give you the time of day. I am reporting them to the Better Business Bureau. If you are looking for solar, be very wary and look elsewhere.
