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

Got Watts installed two phases of solar panels on my roof, 67 panels in total. The job was massive,…read morethe price was fair, and the follow up service was excellent. There were hardware glitches after installation, but the Got Watts team reliably spotted them - without me realizing there was even an issue - and sent teams out to ensure my equipment worked as promised. Years later I noticed some leaks through my roof where some phase 2 panels were installed. I notified Got Watts and they sent large crews to my home to rectify the issue over several days. This was no small fix. They probably spent vastly more to rectify the leaks than they did to install the panels to begin with. No one likes to have problems with an install. But, it means a lot for a contractor to honor their commitment and spend vast sums to honor their warranty, and their word, to their customer. I've had "good companies" make promises they wouldn't honor once the initial check cleared. Got Watts was true to their word and treated me in a dignified manner that is rare these days. I would unreservedly recommend the good people at their firm. Special thanks to Sam Moore and Daniel Harrold for their excellent service.

My mom and I couldn't be happier with the service we were provided from start to finish. We contacted the business in late July of last year to see about installing a solar system on our home before the end of the year. Within in days, Alessandro was here to meet us in person and provided us with a comprehensive breakdown for solar options and pricing. We loved that we were treated like actual people instead of a number in a queue. Given that there was a slight backlog of jobs they had to work through we were assured that we would have our system fully installed and activated before the end of the year, which we did! It was great working with Nick who was our onsite rep and Juan was always available to answer any questions we had by phone (of which I had many). Despite the number of times I called, he was always patient with me and provided detailed answers that gave me a better picture of our installation and how our system would operate moving forward. I can't say enough about how amazing the whole process was. Looking at our electrical bills right now and we're in awe of all of the savings we're getting, which validates our decision to purposefully oversize our system. If and when we decide to install a car charging station in our home we're definitely going back to Sunlight!

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.

Having East Bay Power Systems design install and certify a rooftop solar panel system has been a…read morewonderful experience. Working with the team (Darlene, Jeff, David etc.) to get the system designed and installed was very easy, they took care of everything, including getting the city to approve the design/installation for PG&E. Installation was a simple one day process, and best of all, we were essentially off the grid the next day. Interestingly East Bay Power Systems use American made solar panels (Aptos) and an American made power backup system (Tesla). Not only does the system perform flawlessly, because of there high output of the Aptos solar panels (up to 450W per panel) the whole array of 10 panels is virtually unseen. As an added bonus, they set up a Tesla app on your phone so you can see at a glance how mush power the system is generating, how much is being used to power the house, how much is used to charge the backup system and how much power is being sold to PG&E. For a system this good, overall cost was relatively low, far less than what I was quoted 5 years ago by two different companies. You may have noticed all my reviews to date on Yelp have been 5 star, this is deliberate. Life is too short to focus on that which does not make us happy. This is why I restrict my reviews to those things/places/services that make me happy and appreciate life. Sure, I have been to some really dreadful shops, hotels and restaurants etc., but, like I said, life is too short to spend time thinking and writing about them.

The product is good, the process left us wanting…read more Eric, David, Jose and the crew did an excellent job. My frustration was with the post installation process. 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.

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. Down the street from us, a large cluster of neighbors hired Solar Technologies and I have only heard good things from those I've spoken to.

Enphase communicated to Solar Technologies what they need to do to solve all of our problems, but Solar Technologies is completely unresponsive.

The many moving parts to our residential solar plus battery system, including the various entities, such as PG&E, Tesla, City inspectors, and the financial backers we opted to use all progressed seamlessly and, for us effortlessly, thanks to hard working individuals behind the scenes. In particular, Skyler could not have been more helpful, managing our project and acting as a point of contact. Others included David in sales who demystified the process, Varon who coordinated with the utility to ensure we met all requirements, and Gino, who collaborated with Maxwell Power (formerly HDM Renewable Finance), the clean-energy company that helped finance our residential system. On site, the design and install team did a great job keeping things simple. The entire system, including battery and thirteen panels, was installed according to Ramiros's expert design within just four hours. Good quality hardware was used to tie to the roof, which was inspected by our roofer and given a big thumbs up for not causing problems. But even before that, David our site survey tech, gave us the sense that all would proceed well, as he collected necessary data by drone, and made a favorable first impression with his personable approach. Toward the end of the multi-month process, which included time to get a new roof installed, we passed city inspection with YES tech, Dario, an extremely courteous young man, present to ensure we made it through that last step and PTO (permission to operate). YES has an excellent and well-deserved reputation because of these people and others who worked on our behalf. The company can do better automating some of the process, and to be fair, they say they are working on transitioning to a CRM software solution for this purpose. But, I can say that over a period of several months, I had excellent communication with many helpful people. Skyler in customer service was my primary contact and that made all the difference. My thanks to YES for helping us make this wonderful and complex project a reality. We love our new YES-backed system and look forward to working with the company again in the future.

Wow, I cannot say enough good things about Ryan and his team! I hired them to remove our 69 solar…read morepanels and reinstall them after a re-roofing of our home. It's a nerve wracking process but Ryan gave me reassurance things would go well. Upon Ryan's recommendation, we also decided to replace the solar panel racking system installed by Sunrun because we were plagued with roof leaks due to improper sealing of their footings. Ryan and the Northstar team were absolute champs at removing and reinstalling the new system for us. Everyone we dealt with was so professional, kind and easy going. The work was beautifully done and based on all the photos and detail provided by Ryan I am confident we will be safe from leaks going forward. He also had to coordinate the reinstall with our roofer and everyone handled it so well. I 100% recommend Northstar and the team for this task, and also wouldn't hesitate to hire them for roofing based on their strong work ethic and product with our solar project. The price was fair and in line with other quotes I'd received. A couple of questions unrelated to this particular job have come up and Ryan has gone above and beyond to help me out by providing his professional input. So happy with these guys. Thank you!

Because of the good experience I had with having Clean Solar install panels at my house I reached out to them to see if they would service panels installed by another, and thankfully they accepted the job. After some back and forth with their customer support, they remotely assessed that the inverter failed and they would install a new one for a reasonable price. Clean Solar employee Jose arrived early for the install and he was very polite and relatable. He replaced the inverter and did not leave until he made sure that the system was back up and running and production was being reported in the app. I recommend Clean Solar to anyone needing their panels serviced or to install a new system.

**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).
