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.

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

We can't say enough great things about our experience with our solar installation from Northstar…read moreSolar in Danville. From start to finish, we were so comfortable with every individual we interacted with. Our salesman, Patrick was no pressure, extremely helpful and very responsive. Danielle in the office was a joy and our project manager Jason was there for us all along the way. The install crew was phenomenal and completed the entire project in two days. 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. If you are considering solar power, we highly recommend giving Northstar Solar an opportunity.

Jason and his team jumped right on it and sent someone over to look at it. They went back and forth with Tesla and re-ran some lines, and I was back up and running very quickly!

All of a sudden the panels at my mom's house stopped producing energy and I was in a pickle because…read morethe installer went bankrupt years ago. 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. Jose is an excellent employee and my mom had a great experience working with him.

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!

We first contacted Solar Technologies about putting solar panels on our home in late 2019. We…read moresigned a contract with them in January 2020, right before the Pandemic shut everything down. 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.

Sarah is the nicest and great worker has been my only contact and she is not a technician. I requested a pre site visit to review the job and draw up plans and I was told it is billable. So no pre site visit was ever completed. So removal went well. Install is a disaster. We are now 5 days in and I have no working system. I had 2 inverters and wanted to go to one. I was told the Tesla inverter could do that. Today the team removed my 2 old inverters and mounted the Tesla inverter. They then went to the panels and there was no Tesla MCI to connect to the panels. 18 of my panels might not be compatible with the Tesla inverter. 1, I do not have a building permit. This work is being performed while it is in process. 2. There is no install plan. Every time the installers came I had to be project manager. They did not know I was going to 1 inverter. 3. Even when the inverter was in the truck the team did not know I am going to one inverter. 4. My old inverters have been removed and are not usable. Save yourself my pain hire a reputable solar company.

We have had an Enphase solar installation for 10 years now, which has always worked beautifully…read more However, due to regular PG&E outages in our area (Fremont, CA), we decided to add a backup battery to the system. After careful research, we chose Highlight Solar (HS) to handle this installation. We chose the Franklin battery, and Highlight Solar came out to handle the installation in Nov 2025. Sadly, we had some serious issues with the functionality of our solar infrastructure, after the Franklin equipment was installed... the Enphase solar monitoring device (called Envoy) started having trouble communicating with the panels, and therefore would disable them. HS made a couple of different attempts to fix this issue (which was delayed when they went on vacation for a month), so I had to keep cycling the breaker for the panels every morning to get the system working for another day. Fortunately, they were persistent in pursuing the issue, and after returning from vacation in late January, Samir came out and spent a couple of hours on the phone with Enphase support, who suggested a possible solution for this issue. HS then had someone come out to implement Enphase's suggestion, and now my system is working solidly and reliably (Feb 2026). I'm glad HS didn't just give up on us; I'm sure they were just as frustrated as we were by this situation. We certainly didn't expect this to take three months to resolve, but it is working now.

We met with multiple solar companies and settled on Highlight due to both the great recommendations…read moreas well as our experience during the initial process. We asked a LOT of questions, then we asked more, and then some more. Ali, our salesman, remained patient and communicated thoroughly via email or phone, and at all hours even after we had signed the paperwork. The installation process was honestly better than the sales process. The combination of Chris (the foreman who found a solution for all our requests) and his team which worked in awful weather to get our project installed on schedule were amazing. Our inspection, and final handoff were handled by Samir, who answered even more questions, and made sure we were fully set up. From end to end we had a great experience with Highlight Solar and will recommend them as they were to us. Pro tips: If you get a battery you will need to store it until it is installed. Your solar data might not show up on the app for 24-48 hours after installation...don't panic, it will show up eventually and you will see the money you are not spending with PG&E.

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.

I provided the necessary information for my solar installation (including usage and current costs), but he was very combative when it came time to discuss my project. He refused to discuss a power purchase agreement, instead he tried to force an outright solar panel purchase, which I made clear was not an option. He offered no apology and no clear explanations about his actions. Free advice: if you are not interested in the job, just say so politely. Don't be rude, discourteous, and unprofessional.
