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.

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.

Not only did they offer high-quality equipment and strong expertise, but their pricing was highly competitive and well below several of the other bids we received, which immediately caught our attention. Like many homeowners in California, we were trying to get our solar and Enphase backup battery installed before the end-of-2025 rebate deadlines. Sierra was absolutely slammed with new contracts at the time, yet they still worked incredibly hard to try to get us online before the cutoff. Unfortunately Mother Nature had other plans and some inclement weather delayed the final steps, but we genuinely appreciated that the company prioritizes safety for their crews rather than rushing risky work. That actually gave us even more confidence in the company. From the very first conversation through final activation, the entire process was smooth, organized, and professional. Every person we interacted with was knowledgeable, responsive, and clearly cared about doing the job right. Francis was our initial point of contact and helped us scope the project and walk through multiple system options and pricing. He was extremely knowledgeable and patient while we evaluated what made the most sense for our home. Alex, our lead project manager, was fantastic throughout the process. He was always quick to respond to emails and texts, answered every question we had, and took the time to educate us on how the system works so we felt confident using it. Carlos and Francisco handled the installation and did an outstanding job. They were professional, skilled, and communicative, and the installation itself was impressively efficient and clean. Blair helped bring the system online and walked us through the hardware components and operation once everything was up and running. And behind the scenes, Symone and Gianna in client care and administration kept everything organized and communicated updates promptly, which made the whole process feel seamless. Overall, the experience was excellent from start to finish. High-quality equipment, a skilled team, and outstanding communication every step of the way. We're extremely happy with our solar and battery system and would absolutely recommend Sierra Roofing & Solar to anyone considering going solar.

By the time the solar panels were installed in late 2025, we had signed three contracts with them due to a series of delays dealing with all the idiosyncrasies of our old house. Through it all, our sales contact, Jason Coolman, was patient and knowledgeably answer our questions as they came up. Everyone at Solar Technologies that we worked with was great. They made sure that things went smoothly and on time. We are thrilled with our new solar system. Solar Technologies has been a Bay Area Sunshares vendor for many years and a lot of other reviewers sound like they're as happy as we are.

Unreservedly recommend Clean Solar!…read more Had PV Solar installed when the house was built in 2006. Under our existing rate plan (time-of-use, meaning pay high rates 4-9 pm and low rates the rest of the time), and metering agreement (NEMS 2.0), we were selling more electricity (in $ terms) than we were using. However, we will be forced to switch to the new metering agreement (NEMS 3.0) in late 2026, which drastically cuts how much PG&E pays us for electricity we sell to them--we will end up paying money to PG&E. This motivated me to consider installing a whole-house battery storage system to do "rate shifting"--store the excess electricity generated by our PV system in the morning and early afternoon to power the house during the high rate period (4-9 pm). And of course provides energy in the event of a power outage. I also wanted to take advantage of the energy tax credit before it expires at the end of the year. Reading reviews on Yelp, Google, and other sites, I decided to contact Clean Solar along with 3 other companies. Clean Solar was the first to respond and I had a thorough conversation with a Senior Design Analyst, Art Balaoro. He listened and understood my goals, answered my (many) questions and said he would get back to me with options in a few days. Of the other 3 companies, 2 never responded to my inquiry at all! The other one did, but I had to repeatedly reach out to them to make any progress on getting a quote. In contrast, Art did as he said and responded within a week with several options, primarily around which battery vendor to go with (Tesla vs. Franklin, I preferred the latter) and the battery location. Clean Solar scheduled a technician to come out and look at our house: location and configuration of the main panel, possible battery locations, where the existing PV inverter was, etc. Took a lot of photographs and measurements to verify compliance with building codes. In contrast, the other vendor was sluggish to schedule someone to visit, so I ended up sending them photos and measurements from the Clean Solar visit. Because of the peculiarities of my house's main panel, it was going to be more difficult (and expensive) to install the Franklin battery. And although I would have preferred to put the battery inside my garage, building codes would have required a replacement of the entire smoke alarm system throughout the house, also adding significant expense. Art walked me through these issues thoroughly and so I went with the recommended (and cheaper) option, going with the Powerwall and an outside location. In contrast, the other vendor didn't do as thorough an analysis and wasn't aware of these issues until I pointed them out. When I did get a comparable quote from them (exact same system components), it was slightly more expensive than the Clean Solar quote. I started this process in June, and immediately Art said it was going to be a close thing to finish the project before the end of the year--so many people were wanting to install solar or battery projects and claim the tax credit. Art also walked me through the timeline for the whole process and how it would be managed on their end. Based on the interactions I had with him and others, I felt that Clean Solar was the best choice for my project--and my experience bore that out.

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!

The process was smooth, the communication was quick, and the installation was top notch! The icing on the cake was when the inspectors came and told us that "the solar panel installation was the best" that they've seen. When I asked why they said this, they said that the panels were not drilled into the roof tiles, and that we would never have to worry about a damaged roof or leaks. Those words were very reassuring and definitely gives us peace of mind. Working with Wyndon, Michelle and their crew was a pleasure. Even after the install, we received excellent support and all our questions were answered. We highly recommend them!

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!
