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.

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!

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.

We hired Alcor Solar to install new thermal solar panels for our pool, and the entire experience…read morewas very positive. 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.

Responses were slow and vague; I could not even get a ballpark estimate without repeated follow-ups. My last email requesting scheduling went unanswered, and then--three weeks later--Joe called on May 6 saying he was eight minutes away. I had no idea I'd been scheduled, and I was just lucky to be home. Bottom line: if you can get on Joe's calendar, you'll likely be happy with the repair.

I will sectionalize this review because there were some things in the process I think deserve…read moredifferent ratings. Initial survey and installation scheduling: 3 Stars We signed up to get the solar roof from Tesla in February 2022. In march we had the roof survey. I was told by the surveyor the work that would need to be done to the roof to get it ready for the solar tiles. This price was also reflected in my quote. I was also told there was a delay in the install times due to supply chain issues. I was told to expect a call for scheduling in May or June. By early November, I had not heard anything yet. So, I called customer service to check the status. The rep was very helpful and got my install scheduled for the 3rd week of November. About a week or so before the install, I was called by Tesla and told that after reviewing my plans further, it looked like a small area over my garage didn't meet the pitch requirement for the solar tiles so, an alternate roofing material would have to be used. I was also told it would blend in nicely. I was also told the price would be a little more for this additional material (3k more). They told me they wanted to let me know before the job so I could back out if I wanted to. I was happy they told me about and proceeded with the install time. This part of the process I rated 3 stars because I was not called by Tesla for the install time and the small area of the roof that didn't meet the requirement wasn't mentioned on the initial survey. Installation Crew: 5 Stars The installation week arrived and the crews that came out did a great job. The crew leader's name is Geronimo and his team is called "Colussus" out of Martinez. They were on time, worked quickly, were very polite and accommodating. The whole install went off without a hitch. They did it over 2 weeks. The first week was sub-contracted where they did the tear down, decking, underlayment and the area of the garage that was not going to have tiles. This took 3 days. The second week they did the Powerwall install and solar tile install. This took 3 days as well. After the Powerwall was installed, the crew went over the Tesla App and all features in it with us. This was very helpful. Geronimo also went over with me the hazards and safety things if I have to walk on the roof for work on my HVAC system. He even provided a safety mat to put on the roof to prevent slipping while walking on it. He and his crew had great customer service. Initial Roof Completion: 3 stars When the roof was initially "finished," the untiled area over the garage did not blend well or look good with the solar tiles. This is because that part of my roof was coded in the design plan as a "Flat-roof," even though that part is just under a 3:12 pitch. Therefore, it was finished with a black rolled composite material you find on flat roofs. This wasn't the fault of the install crew because they can only do what is in the plan. But, this was an issue with the initial survey. Project Advisor: 5 Stars My Project Advisor's name is Michael Kielbasa. He was great! He was very knowledgeable about the product and answered all my questions prior to the install. He was very responsive and got things done quickly. When the roof was initially "finished" I sent him a picture and told him the material over my garage does not blend well and it made the roof look unfinished. I asked him if there is any way we can put non solar producing tiles in the section after all since there is some pitch and it's not flat. If not, I asked him if we could have a different finished installed instead. He sent the pictures and my concerns to the operations and install team. He arranged for the install crew leader, Geronimo, from the install team come out and measure the pitch of that section to reassess if it actually is possible to have the tiles installed there. Geronimo said he was comfortable that it could be done with no pooling/drainage issues, but had to get clearance from his supervisor. Shortly after, Michael emailed me and told me they got the green light to install the tiles in that section after all. They had the crew out the next day and they completed it over 2 days! They also did not charge me anything additional. Michael was great and I was very happy to have a Project Advisor that helped put our minds at ease during the entire process with great customer service! Actual Roof Completion: 5 Stars After the crew came back out and finished that untiled section, I was very happy with the finished product. The roof has held up will through a couple weeks of heavy rain and wind. It has been producing well although I have not yet seen its full potential because of the weather and clouds. Overall Experience: 4 Stars I'm rating my experience as a whole as 4 stars because although a lot went right, I did have to be my own advocate with certain parts of the process (Scheduling, Initial finished look). However, they were quick to correct these things
