I work in the power systems industry and had lots of technical questions and inputs on the design. My installer, Manny Rios, was deeply technical and knowledgeable about the systems he installed.

We are still dealing with a few minor issues but I'm grateful for the attention to detail and ability to address my detailed concerns. Thanks!

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!!

A Team That Actually Cares About Their Work…read more From the start, Solar Harmonics stood out because they treated me like a person, not just another lead. Jamie and his team were responsive, clear about costs, and never pushed anything unnecessary. The installation crew showed up on time, worked cleanly, and left my property spotless. They installed 19 panels with Tesla Powerwall 3s at my home in Antioch, and everything has been running perfectly since day one. The panels look great, the Powerwalls perform flawlessly, and the app setup was smooth. It is rare to find a company this transparent and easy to work with in the solar world, but these guys nailed it. I highly recommend them. Gordon & Jana

Which resulted in prolonged failed solar generation. Eric, rather than blaming the problem on anything or on me offered 2 extra panels in compensation.

That's my Synergy story. Richard Kamp

I highly recommend Synergy Power for residential solar system installation. Dave, the salesperson,…read morecame to our house and made valuable recommendations for best suitable system to install. He also gave us a price breakdown and how much could be saved over the years running the system. The installation was completed in half a day with an efficient crew to install the panels, battery and inverter. The whole system was up and running in minutes after installation. At the end, Phil would appear at our house and get things ready the date the city inspector came for full inspection. Everything went very smoothly and all papers were properly signed off. I just enjoyed working with this company and they are professional, knowledgeable and nice to communicate with from beginning to end. Again, I highly recommend Synergy Power for your solar project.

We were interested in solar for our 1940s home and provided a deposit in good faith. However, after further inspection of our roof and the overall project viability, we decided not to move forward. When we requested our deposit back--before any equipment was ordered or installation began--the company initially refused, claiming it was 'passed' the point of a refund. It was a high-pressure situation where we felt they were trying to lock us into a contract we weren't comfortable with. While we did eventually receive our deposit back after pushing the issue, the initial refusal to return funds for work not performed was a major red flag. Homeowners should be very careful with the fine print here. If you are looking for a company that values transparency and customer comfort over just 'closing the deal,' I would suggest looking elsewhere. We're glad we didn't get stuck with them and are instead putting that money into improvements that actually fit our home.

Hello everyone, I…read morehad a great experience with Solar Sesame. I had my system installed in December 2025 and wanted to wait a bit to see how SS and GoodLeap handle follow-up on the project, Closeout issues, and customer service follow-up. Since my December 2025 installation and the January 2026 activation with PG&E, I have been more than happy with their service. I had put off getting solar for a while (bad decision on my part), so when the $1,100 PG&E bill came in last summer, I knew it was time for a change. Solar Sesame's pricing consultation was pleasant and informative. I had done plenty of research, so I knew my stuff, and being in Construction helped as well. Both their Sales Rep and Installation Lead were informed and knew their stuff. My Project Submittal documents to the City of Danville were professionally done. The building permit was obtained quickly, and the installation was completed within a few days. We did have an initial hiccup with the materials delivery; it arrived too early, but SS had it picked up and redelivered the following week. All in all, a solid performance from Solar Sesame!

We absolutely love having battery backup especially from 4 to 9 PM when PG&E charges the highest peak rate in the Continental U.S. California has the second-highest electricity rates in the U.S., (only behind Hawaii) which makes receiving power from the sun especially rewarding.
