We had backup battery systems installed at two different homes--one in Napa and one in Marin--and…read morehad an excellent experience working with SonoMarin Solar on both. The original solar systems were installed years ago by SolarCraft and Ambrose. When it came time to add a backup battery in Napa, we chose SonoMarin first. That project went so smoothly that we later asked them to install a battery on our older, more complex Marin system as well. Despite the added complexity, they handled both installations efficiently and got everything up and running without drama. Ayelet in the office deserves special mention. She provides near-instant responses to texts and emails, keeps everything moving, and somehow manages to coordinate all the moving parts with ease. If you've ever dealt with solar projects, you know how valuable that is. She had seemingly infinite patience for my never-ending questions, handling them with professionalism and speed. She also helped me apply for relevant rebates and helped interface with the nightmare that is PG&E, making it all look easy. The whole team jumped through hoops to get the system in before the tax break expired. SonoMarin is a small company, localled owned and run by the same people I originally worked with at SolarCraft on our first install years ago, which really shows in the level of care and accountability. Avner and Nick have built a great company. Pricing was competitive--frankly, all three bids we received were in the same range--but the execution and communication set them apart. I would recommend SonoMarin without hesitation.

Amazing in every way!Incredible service and great group of people who love what they do!!win//winread more

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!!

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.
