I first reached out to Diablo in 2020. I was solar-curious, but I determined at the time that it…read morewasn't what I needed. This year (2024) I decided that my electric bill was just too much, I was going to get solar eventually, and the longer I put it off the more it would cost me overall. I liked that they didn't harass me. Once some folks get your number they just wont stop calling. Diablo didn't bug me back in 2020 and they were not really trying the hard sale this time either. I called them, had a brief discussion about what I was looking for, and scheduled a visit. I didn't know much about solar installations, so I spoke with a friend who was familiar with these things. He told me what to look out for in terms of equipment. After I got the quote, the folks at Diablo were very helpful answering questions along these lines. Again just providing information, not trying to sell me. Diablo handled everything and scheduled a time to do the install. Overall it took about 3 days. Two days for most of the hardware and then a day about a week later to deal with the mess in my breaker box from some previous work done by another company. Then they handled everything with PG&E and about a month later everything was cleared on PG&Es end. This delay was due to PG&E processing paperwork. Overall it's working well. Just see the before and after photos below. Not of my roof but of my electric consumption. You can see some before and after values as well as how the system performed on a particularly hot day.

While their price was actually the highest of the 3 company bids received, the difference was marginal and the communication/information/responsiveness by Got Watts was far better. Day to day as the project proceeded, there were problems and we'd solve them. No project of this scale will proceed without a few hiccups. In retrospect I think it went very smoothly. I found 100% of the personnel to be professional, dedicated, knowledgeable, and cheerful. They did everything they said they would, at the price agreed-on, and I'm very pleased with the result. I'm glad I went with Got Watts.

My husband and I dug in our heels FOREVER, when it came to getting solar. There were all kinds of…read moresalespeople who came to our home on a monthly basis, and we just never had a real peace about being able to trust what we were being " sold", or told. My parents purchased solar from a HORRIBLE company that sounds a lot like 'SunFun'. After they passed away, and the house was sold...we were STILL making the monthly payments for over a year!!! That SunFun organization REFUSED to transfer the solar to the new homeowner, and eventually stopped taking or acknowledging our calls. It wasn't until we had to threaten the new homeowner with a lawsuit that SunFun finally transferred ownership. Due to this, we could not trust any of these solar companies...that is, until Kevin Bedard came to our home, and explained everything in great detail to my husband and I. He took the time to hear about our concerns, and he showed us how he truly cared. That same week, we spoke to two other families who shared their positive experiences about Ambrose Solar that made us feel that we would be in great hands. We had FINALLY FOUND A PEACE about getting solar on our home; KNOWING we would be in good hands, and we were ALL IN. It's been six months now, and we are beyond pleased with our solar panels, and the two Tesla batteries we have purchased. We are true fans, who have NOTHING but RAVE REVIEWS for this company. If you don't have solar, or if you need to add solar, Kevin Bedard is your man! and Ambrose is your company. Every employee has been amazing and helpful. In a world where customer service has taken a dump, this company has remained a class act. So again...if you are considering solar, call Ambrose, and tell them Albert and Rhonda sent you.

My project is now finished and it's been about 6 months turned on and functioning- I'm still so…read moreglad that I did this with Ambrose Solar. Any home renovation project has bumps, and this one had its fair share: after initial install they monitor the systems production remotely to see if it's doing what it's supposed to/expected to, and my system was initially under-performing. They caught it and sent out a team to problem solve it, which took a couple tries, but they didn't drag their feet, they kept on it and kept at it and got it resolved. It was no fault of theirs, just a technology glitch. Core fear was that they would give up after a couple failures and leave me following up with them to get it done, but I never had to worry about that. I also did not end up liking where they placed the control box- it was something that was going to make future maintenance of my house trim problematic down the line. They willingly moved it up a few inches for me (and my only complaint was the team that did that didn't patch the original hole as efficiently as they should have. If I had understood the box placement better on the first pass that would never have happened, so this is a bit of a complaint of my own making.) Jon Landsman, who sold me the system, stayed with us the whole time tracking the project, checking in, and following through on every detail, every question, every concern. He never made me feel like the demanding diva that I am, was always prompt and gracious! The bottom line is that start to finish, even with a few bumps in the road, I have zero question that this is a company that legitimately cares about doing what is right. The culture of deeply valuing customer service that they have built is unmatched by many businesses these days. I am SO pleased, and SO impressed, and I can promise that you will be too!

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.

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.

We could not be more delighted with the results we achieved working with the team at Your Energy…read moreSolutions. 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.

After a year of dealing with a non-functioning solar system, I finally found the right company to…read moreget everything back up and running. I can't say enough good things about the team, especially Andy, Carter, and Manny. From the very beginning, Andy was professional, responsive, and genuinely committed to finding a solution. He took the time to explain what was going on with my older system and walked me through the repair options without any pressure or sales tactics. Carter and Manny handled the installation schedule and repair work, and their knowledge and experience were immediately obvious. My solar system is over a decade old, and many companies would have simply tried to sell me a completely new system. Instead, they carefully diagnosed the problem, sourced the right equipment, and got my existing system operating again. Their attention to detail, workmanship, and pride in their work were impressive. What stood out most was the customer service. Every question was answered, communication was excellent throughout the process, and the entire team treated my home with respect. It's rare these days to find a company that combines technical expertise with genuinely outstanding customer care. The system is now producing power again, and I'm thrilled to see my solar investment back in action. If you have an older solar system that needs repair, or if you're looking for a company that truly stands behind its work, I highly recommend Your Energy Solutions and their entire team. Thank you all for your professionalism, honesty, and dedication. Five stars well deserved!

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).
