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.

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.

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!

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.

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.
