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.

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 saw him at the neighbors and I said to her I wouldn't use him. He is rude. He then started smarting off again. I walked to the neighbors yard standing on the sidewalk and was confronting him about his rudeness. He then said that when I told him no I was hiding behind my screen door. I told him that I wasn't behind my screen door anymore. He said if I touched him, he would own my house. However, he never stopped talking rudely. My wife got 90% on camera plus the nest. He then said, you just blew up the neighborhood. He then decided to leave and we continued to argue as he walked past my house. He never stopped talking crap as he went down the block.

They helped me throughout the process including obtaining permit from City of San Ramon and the on-site inspection. Few other installers that I talked to suggested absurd things like getting permit from San Ramon is impossible (or) permit process is so "trivial" that I need to take care of it myself. Few others who claimed to help with the permit process charged much higher price if permit was needed. Installers were also professional and completed the job in about 2 hours on the day of install. Overall, I liked their thorough methodical process and as their name suggests they indeed offer a Quality Electrical Solution.

When my SolarEdge inverter failed, my solar panels stopped producing power. I reached out to Solar…read moreService Call, and during our initial conversation, they promptly identified that a replacement inverter was required. They took the initiative to contact SolarEdge on my behalf and successfully secured a replacement unit under my existing warranty at no cost. They informed me they would follow up once the new inverter arrived. Shortly thereafter, I received a message confirming its arrival and offering to schedule the installation. They were flexible and worked within my availability, which I found very accommodating. The technician who arrived was professional and respectful. Since my car was parked next to the inverter, he asked if I could move it so he would not accidentally damage it during the work. That level of thoughtfulness stood out to me. He completed the replacement efficiently, verified that everything was functioning correctly, and gave me time to ask any questions. The following day, I received an invoice for the labor, which was competitive. I believe the cost was considerably lower than what many other solar companies would charge for a similar service. Overall, I am completely satisfied with both the quality of work and the level of service. If your solar system is not functioning, I recommend reaching out to Solar Service Call. Even if you are considering calling your original installer, it may be worthwhile to see what Solar Service Call can offer. You could receive excellent service at a more competitive price.

Do not purchase solar from this company!!…read more We purchased the system in 2021. Come to find out, they overcharged us by a significant amount and gave us an older inverter and did not actually recommend enough panels. We didn't do our research but shame on them for not being ethical. Our true up bill has been about $600 each year so that is expected and still saving us money even with the over charge and too few panels. However starting in 2024 things changed. The timeline of failures: 2024 System Failure: The system was completely offline for multiple weeks over the year, causing our utility true-up bill to increase from ~$600 to over $2,000. Delayed Service: We reported the outage in December 2024. Service was not completed until April 2025, extending the period of failed production. April 2025 Service & New Failure: Technicians restored solar production on April 11 but caused the system's battery to fail, rendering it useless for backup or consumption. (We requested the battery to be switched to max consumption which never happened so we have been losing money from that as well.) September 2025 Catastrophic Failure: During a battery replacement, the technicians caused an electrical short that destroyed the inverter. The system is now completely inoperable with zero production from solar or battery. Ongoing Impact: A replacement inverter is not expected until December 2025, exposing us to further excessive utility costs from 100% grid consumption - literally it's as if we have no solar but we are still paying our monthly loan amount and paying for all the power from the grid. Management continues to deny any compensation for lost production, stating they don't guarantee performance issues. There are no performance issues, literally there is zero performance as there is no inverter and no battery. Do not buy from this company, as you can see from BBB and other reviews they are not to be trusted!!!
