Synergy owner Eric Piekarczyk recently demonstrated proactive ethics that are hard to find. The…read morecompany failed to assist in diagnosing a component known as a Gateway in my pv system. Which resulted in prolonged failed solar generation. Eric, rather than blaming the problem on anything or on me offered 2 extra panels in compensation. This says that the company like all of us is imperfect and that the owner has a high ethical bar. In a time when our country is being governed corruptly something like Eric's behavior shines. That's my Synergy story. Richard Kamp

I highly recommend Synergy! I thoroughly investigated different vendors for my home solar system,…read moreand Synergy really stood out for their professionalism, knowledge and customer service.

A neighbor referred a company to me, and ultimately I fired them as they ghosted me. Then, I started with company number two. Again I was ghosted. In 2024, Chris and Kingdom Solar were recommended to me. When I talked with Chris, he assured me that he would not ghost me and he has been true to his word. The work and the communication from Kingdom Solar has been top notch. The system on the main house was completed in 2024 and the one for the ADU in 2025. There were some small issues along the way, but Chris and his team were communicative and helpful in resolving the issues. I highly recommend Kingdom Solar.

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!!

This is my second time around with Clean Solar, and they are just as stellar as the first time, if…read morenot better and more efficient. We needed to add panels because we purchase an EV and needed more solar to offset PG&E. The impeccable experience started with Art the consultant, he gave 4 scenarios and explained in detail what each means and provided detail report including all the tech details and break even timing. To be honest, it was too much for me, I really just wanted pricing and how long it takes to install haha but was good to know he has such knowledge and I was confident he is looking out for my best interest. Then we had Patrick the PM, arrived for site inspection on time and courteous and explained the whole process. Then come the impressive installation team Luis, Alberto and Kevin. The 3 arrived on time and with smiles, just overall a great vibe from them. Luis walked me through the installation plan and gave a few choices taking into consideration aesthetics of the house and then got to work. 4 hours later, clean line, fine craftsmanship and symmetrical matching placement from last system is in place and ready to tangle with PG&E (attaching some photos) I really really can't recommend any higher to go with Clean Solar on your solar projects. Seamless is what you'll experience with them. Until next time Clean Solar!

**Update: Carl contacted us to apologize for the few negative experiences and they will definitely…read moretake our feedback seriously and will address and improve these issues. Btw I was going to bump this review to a 4 but working with Nick we decided on 5.** We had a complicated full house renovation this year and signed with Clean Solar for either the Tesla tiles or solar panels and we ended up choosing solar panels + Tesla power walls. I want to give special thanks (and the only reason why I didn't give a 0 star) and appreciation to the members listed as they deserved beyond 5 stars Bill, Nick, Jeremy, Rodger, Louis, Kevin, Albert, Alberto, Carl (CEO). Bill was amazing and helpful in explaining the process and helping us secure the initial funding. You are probably wondering why I am giving this solar company a 3 star. Well it takes 1 bad apple to ruin a team and this is the case. A three day project ended up taking 3+ weeks & we understand that the workload is extremely busy this time of year. However when 1 person is acting unprofessional, crossing the line, asking homeowners to borrow a usb cable to charge their cell phone, super loud, tries to impress (why), doesn't listen to clients (would walk away in mid conversation), act as if he is the owner of the company, talks way too much (not in a good way), talking about his side hustle business, a bit juvenile, not completing and complaining about the job in front of clients plus not showing up when he said he would to complete the job, leaving tools at the site and asking the homeowners to put it in their garage until he returns to pick it up, calls in sick last minute leaving the load to other team members plus more well then this becomes a problem and 0 stars (if possible) especially the amount of money you invest into this project. We also requested that this person not show up again but they kept sending him back. At the end of the project half of the Tesla walls were connected and working but the other half wasn't connecting. At one point our bedrooms electricity didn't work, it wasn't the breakers and Nick was awesome enough to take our after hours call and help us manually override those other 2 disconnected wall panels. The dream team (Nick, Kevin and Albert) resolved the connection and all is working now. Also, Nick stayed late to make sure our Tesla walls were configured and updated properly. Plus , a shout out to Jeremy for staying late as well to help fix a broken issue. Feedback: Organize a team that works well together to effectively complete the project. Provide sexual harassment training (this is excluding people listed here). If a female client doesn't feel comfortable with a person don't resend them back. Also if a homeowner (regardless of being the wife) calls and leaves a message please out of courtesy call back after all I am the client, work and pay the bills too (even though this is my husband's project).

I got answers from Darlene that did not make sense. Sometimes her computer was down other times her phone was down. Sometimes she would call to give me a message only to realize that she had called the wrong customer. Did not enjoy working with her. Finally, Kara engaged and we got the Permission to Operate about two months after the install. Supposedly Jeff (the Business Owner) is no longer with the company and has gone back East, so not sure who is leading their future efforts. For future customers: hang on to a portion of the payment till the Permission to Operate is received not just the installation.

I was in a tough position when my original installer had gone out of business and I had a part fail 4 days after warranty exprired.

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!
