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.

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.

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.

Theses panels have done an incredible job of heating our pool throughout the years, thanks to Diablo Solar maintaining them. Recently we had to replace our roof. Diablo Solar worked closely with us to take the panels off and put them back on right before and right after our roof was replaced. The crew did an amazing job! They were super polite, friendly, knowledgeable, professional and considerate. Zach, Gary and Joe took the panels off. They carefully placed them in our yard and did not damage a single piece. Zach and Julian put the panels back on our roof perfectly. They look beautiful and are again heating our pool flawlessly. They helped to make our roof replacement so much easier and I truly appreciated their hard work. I would highly recommend Diablo Solar Services!

I offered to pay the one hour of labor that would he have been expected (as I simply wanted to system to work and felt this was fair). They arrived promptly and made the fix. Since then the system has been working fine. I suggested some changes to their customer service model as all of these issues could have been easily avoided. I appreciated his call and rapid response.

This is the worst company I have encountered when hiring contractors and paying for membership…read moreplans through the years. Green Air actually took over Certified Heating's clientele (I was with Certified for 2 years) and they were wonderful. After they took over, they already cut down our maintenance visits from 2x a year to 1x a year. I wasn't too happy about it but the techs that came were nice and cordial. However, I'm not really sure what's going on. Maybe new management. I had my last maintenance service done in 6/2025. I moved in Dec 2025 and transferred my service to the new address. I scheduled a maintenance service for end of this month and just last Thursday, I got an update email that they were downgrading and removing all HVAC tune ups, air filter changes and solar cleaning. Basically all the benefits that I chose to pay the membership. What really angers and frustrates me is how no one is picking up their phones and it goes straight to vmail. When I did finally get an email reply, they stated that they would only apply my 5 month payments to the maintenance fees, so they basically didn't count the previous months I paid at my old home. I feel like that is pretty unfair, that I paid a full year to have no maintenance included and I would have to pay more money on top to match whatever fee they say maintenance services are currently. They didn't offer a refund or that my service I already scheduled back in May would be taken care of. Now I just want to cancel and take it as a loss since I can't get a clear answer. I will have to find a new company that hopefully cares about their customers.

For the last 14 months, I've been paying my monthly fees faithfully, yet I haven't received a single service visit. No maintenance, no proactive calls, nothing. Their billing system is a disaster and their communication is nonexistent. The breaking point was a call I received today. They told me they updated their billing system and needed to collect payment again. When I pointed out that I've been paying for over a year without a single person showing up to do the work, and that they have zero records of calling me to schedule.. they flat out refused to admit it. I asked to speak to an owner or a manager to resolve the refund for the service I never got. Instead, a man got on the phone, spent the whole time talking over me, and then actually HUNG UP up on me. Now, every time I call back to finish the conversation, it goes straight to voicemail. It is honestly ridiculous that a customer has to chase a company down to get them to do the job they are already being paid for. To be treated with such disrespect after four years is a slap in the face. Save yourself the headache and go with a company that actually values its customers and answers the phone.

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.

Sue, the office manager, was great to work with--she was responsive, helpful, and kept us informed throughout the process. Joe came out to provide the estimate, and he and another installer completed the installation in just one day. They recommended using a pool cover to help retain heat overnight when temperatures drop, and that advice has worked well for us. Since installing the system and using the pool cover, our pool temperature has been averaging around 82°F in the morning and warming up to approximately 85-87°F during the day. We haven't experienced many really hot days yet, but so far the system is performing exactly as we had hoped. We're very happy with our decision and are glad we finally made the switch to solar.
