I was hoping my interactions with this business would be positive, but it was not. I spoke to Jeff…read moreand unfortunately he was unprofessional and discourteous. 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.

It is late September 2024. And we just saw our latest PG&E bill. YIKES!…read more We got a random door knocker that came by to inform us about solar. I had previously talked to SunRun via Costco and am pretty nerdy, so I had done some homework by now. The door knocker talked about solar and battery storage and gave us a quote. That quote would be better than SunRuns. In my research about that quote, I found several reddit posts about solar and specifically Tesla PowerWalls and their pros/cons and service. One thing that kept on popping up was that the actual battery and system is great, the service and parts can be more miss than hit. But there were these Ask Me Anything posts from a guy named Jeff. He provided great advice to everyone. People with general questions, to people with problems to people that had just about had it with Tesla support. What I took away from that was that Jeff was a great guy, very knowledgeable and very open to helping people, even if they were not his clients. This is the kind of person that I be if I were to run a business and someone that I would want to support. I looked on yelp and found Jeff and East Bay Power Systems. All of the reviews there were pretty emphatic about Jeff and EBPS. I called EBPS and promptly was given a quote. Their number was very fair. So now we're nearly at the end of November and we get another huge PG&E bill. Couple that with the new administration coming in and not knowing if the solar/storage incentives will go away after the new year, I call up Jeff again and not only is he able to source a PowerWall, while other companies said they are all out of stock, Jeff said that if I signed within the week, he would be able to have us installed before the end of the year. We promptly signed and the wait began... All of a sudden, the previously non existent rains started to fall and our install date was getting pushed out. I started to get nervous as I didn't know if we would actually get this installed in 2024 or not. I was anxious about the incentive and would call EBPS pretty regularly. 5 days before Christmas and there is finally a open window. The skies have mostly cleared and it was safe for their crew to be on a roof. The install crew lead by Eric show up on time, panels are delivered and the battery is on site. By mid day, they are almost done. If not for things that were out of their control, they would have been able to complete the whole job within the day. It took them 2. Still, very fast and very professional work. Eric is a top notch installer and lead. Come time for the permit inspection, there were very small things that the inspector found which is pretty typical; those were subsequently rectified and we got signed off. In the interim, there was a hardware issue with the PowerWall. And almost to a T, the interaction went just as I had read so many times over and over again on the various Reddit posts. EBPS came out and did some diagnosis but they were not able to fix the issue that day. It really was a PowerWall issue. So I was told by Tesla, after nearly an hour on hold that they would send a Tesla tech out to look at it, but it could be up to 3 months from now. I kept in touch with EBPS and they were able to secure another unit. In maybe a couple of weeks, they were back out. They removed the old PowerWall and installed a new one in a couple of hours. If it wasn't for EBPS, I would likely still be waiting for Tesla. Just as many of the reddit posts said, it really comes down to your local installer and their customer service and their ability to pull strings over at Tesla. It was at this time that I really was glad that I went with EBPS. Because I got the Tesla PowerWall and gateway, it would be very easy to also install a Tesla charger. I purchased a universal charger and I had EBPS install that as well. That went swimmingly. Other than a few communication issues, and the timing anxiety that was totally out of their control, this has been as all of the other 5 stars have lead me to expect. I would absolutely use EBPS in the future and would recommend them to my friends and neighbors.

I desperately needed a roof on my house before the rainy season started. I also wanted to get…read moresolar because it was clear that energy prices are going to continue to rise and solar is the smart way to go in this climate. I also replaced my gas furnace with a heat pump, so our electric needs are significant. A new roof with complete tear off and new plywood is a big project. I started by getting a quote from Solar City but they weren't able to coordinate with a roofer. Their leasing agreement (aka PPA) also had some provisions that seemed pretty predatory. I don't remember if Solar Sesame cold called me or I called them, but I do remember that Marcel did a great job of explaining the process. I'm pretty knowledgeable about these kind of projects so I asked somre very detailed questions. When he wasn't able to answer them immediately, he didn't front, he just said he didn't know and called the office for better info. That's the best response. I was a little concerned that Solar Sesame used an outsourced the roofing to a vendor. But given the time constraints, that was a good decision. Also, the vendor they chose, Arts Roofing, was a joy to work with. They communicated well, and when there was a small problem, they handled it professionally and entirely to my satisfaction. The solar panels went up super fast and well. They system was generating power the as soon as the installers were done. Unfortunately, PGE took their sweet time getting the final inspection done. So PGE got some free kwh from the system. On the good side, we didn't start paying for the system until after PGE did the final turn on, so no problem for us. I monitor the system via the PGE site as well as the Tesla app. Those two systems match up perfectly so I am happy with the amount of power being created and sold back to PGE. Also, we had a short power outage in our neighborhood, and it didn't impact us at all. The only reason I knew about it was that PGE alerted us via text. I looked out my window and noticed that none of my neighbors had their lights on. Between Marcel (sales) and Mei (project management), I'm very happy with the end result and the process on this large residential project.

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.

I actually first contacted Sunlight Electri-Cal very early on this year, in April. I had closed on…read morea new home but knew we would want to get solar installed. Juan was very responsive and came out to take a look at our home right away. What I loved about Juan and his team is they are NOT sales people, they're real engineers who are focused on solving your problems and meeting your needs. Juan and his team are true solar experts and know exactly what they are doing - they were great at walking me through key details I should know about the system, how to best take advantage of having a solar system, and did their best to get me scheduled (in spite of multiple difficulties) for installation before the end of the year. Just for context, I've talked to another solar company where clearly they were just about trying to close the deal and sell sell sell, which really turned me off - it felt like they just wanted our money as opposed to wanting to understand what we really needed. Juan's team really shined here by just showing up to be real experts who are thoughtful about what system you need, as opposed to trying to close a deal. Juan and his team were also really patient and flexible. Our new home's solar system had to be turned on before we could start any work, and that process took months due to Sunnova going bankrupt. And, they were also really thoughtful when we mentioned we had added in some upgrades that would affect electricity use (ie saunas and outdoor electric heaters), and they reassessed their initial project and updated it to accommodate that. I thoroughly enjoyed working with them and am really grateful that we got our project done so well!!

Unreservedly recommend Clean Solar!…read more Had PV Solar installed when the house was built in 2006. Under our existing rate plan (time-of-use, meaning pay high rates 4-9 pm and low rates the rest of the time), and metering agreement (NEMS 2.0), we were selling more electricity (in $ terms) than we were using. However, we will be forced to switch to the new metering agreement (NEMS 3.0) in late 2026, which drastically cuts how much PG&E pays us for electricity we sell to them--we will end up paying money to PG&E. This motivated me to consider installing a whole-house battery storage system to do "rate shifting"--store the excess electricity generated by our PV system in the morning and early afternoon to power the house during the high rate period (4-9 pm). And of course provides energy in the event of a power outage. I also wanted to take advantage of the energy tax credit before it expires at the end of the year. Reading reviews on Yelp, Google, and other sites, I decided to contact Clean Solar along with 3 other companies. Clean Solar was the first to respond and I had a thorough conversation with a Senior Design Analyst, Art Balaoro. He listened and understood my goals, answered my (many) questions and said he would get back to me with options in a few days. Of the other 3 companies, 2 never responded to my inquiry at all! The other one did, but I had to repeatedly reach out to them to make any progress on getting a quote. In contrast, Art did as he said and responded within a week with several options, primarily around which battery vendor to go with (Tesla vs. Franklin, I preferred the latter) and the battery location. Clean Solar scheduled a technician to come out and look at our house: location and configuration of the main panel, possible battery locations, where the existing PV inverter was, etc. Took a lot of photographs and measurements to verify compliance with building codes. In contrast, the other vendor was sluggish to schedule someone to visit, so I ended up sending them photos and measurements from the Clean Solar visit. Because of the peculiarities of my house's main panel, it was going to be more difficult (and expensive) to install the Franklin battery. And although I would have preferred to put the battery inside my garage, building codes would have required a replacement of the entire smoke alarm system throughout the house, also adding significant expense. Art walked me through these issues thoroughly and so I went with the recommended (and cheaper) option, going with the Powerwall and an outside location. In contrast, the other vendor didn't do as thorough an analysis and wasn't aware of these issues until I pointed them out. When I did get a comparable quote from them (exact same system components), it was slightly more expensive than the Clean Solar quote. I started this process in June, and immediately Art said it was going to be a close thing to finish the project before the end of the year--so many people were wanting to install solar or battery projects and claim the tax credit. Art also walked me through the timeline for the whole process and how it would be managed on their end. Based on the interactions I had with him and others, I felt that Clean Solar was the best choice for my project--and my experience bore that out.

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!
