We have had an Enphase solar installation for 10 years now, which has always worked beautifully…read more However, due to regular PG&E outages in our area (Fremont, CA), we decided to add a backup battery to the system. After careful research, we chose Highlight Solar (HS) to handle this installation. We chose the Franklin battery, and Highlight Solar came out to handle the installation in Nov 2025. Sadly, we had some serious issues with the functionality of our solar infrastructure, after the Franklin equipment was installed... the Enphase solar monitoring device (called Envoy) started having trouble communicating with the panels, and therefore would disable them. HS made a couple of different attempts to fix this issue (which was delayed when they went on vacation for a month), so I had to keep cycling the breaker for the panels every morning to get the system working for another day. Fortunately, they were persistent in pursuing the issue, and after returning from vacation in late January, Samir came out and spent a couple of hours on the phone with Enphase support, who suggested a possible solution for this issue. HS then had someone come out to implement Enphase's suggestion, and now my system is working solidly and reliably (Feb 2026). I'm glad HS didn't just give up on us; I'm sure they were just as frustrated as we were by this situation. We certainly didn't expect this to take three months to resolve, but it is working now.

We met with multiple solar companies and settled on Highlight due to both the great recommendations…read moreas well as our experience during the initial process. We asked a LOT of questions, then we asked more, and then some more. Ali, our salesman, remained patient and communicated thoroughly via email or phone, and at all hours even after we had signed the paperwork. The installation process was honestly better than the sales process. The combination of Chris (the foreman who found a solution for all our requests) and his team which worked in awful weather to get our project installed on schedule were amazing. Our inspection, and final handoff were handled by Samir, who answered even more questions, and made sure we were fully set up. From end to end we had a great experience with Highlight Solar and will recommend them as they were to us. Pro tips: If you get a battery you will need to store it until it is installed. Your solar data might not show up on the app for 24-48 hours after installation...don't panic, it will show up eventually and you will see the money you are not spending with PG&E.

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!

When I first inquired, Tim (the owner) reached out and scheduled a consultation/evaluation of my existing system for the following day. He arrived on time, was professional and very knowledgeable. He sent me over a couple different proposals that he believed would be best for me and my usage. I reached out to competing companies to test the market and one company found out that I was on a different NEM standard than we previously thought. This discovery made me second guess getting solar for the time being. I reached out to Tim and he said that he estimated I would still need to upgrade but that I could give it a few months to see how my energy bills were in the winter and early spring. To say he was right was an understatement! My bills went from $60 to over $300 some months. Now that I knew that adding to my system was worth it and had more information, I reached back out to Tim. He didn't miss a beat in suggesting a system that maximized my output and didn't break the bank. (Mind you, he spent hours going back and forth with me answering questions and concerns I had) Ultimately, I chose to go with Tim because of his expertise (he was an electrician prior to starting Golden State Solar), professionalism, customer service and honesty. He never pushed me to make a decision and gave me multiple options that he believed were best. The permit and installation process were painless and completed within a couple months (mostly waiting for the permit). The system drastically increased my solar output and I couldn't be more happy with my choice to go with Golden State Solar!

Tim, Nick, and their team installed our new system within just a few days.

After installation, one panel showed as offline. The team promptly replaced the microinverter, but the system still wasn't performing optimally. They came back out and replaced the panel, ensuring everything was working as it should. Recently, I noticed an error with one of the microinverters on the app. I reached out to Tim, and he responded within a day to resolve the issue.

We were tired of dealing with PG&E power outages and wanted to reduce our electric bill. Simmitri was one of the businesses we got in touch with. Nick and Cole were very helpful with getting us a quote for solar and roof replacement. Especially with the crunch for people wanting solar right now due to the NEM 3.0 changes that are coming in April. They even got me on a 4-way conference call with the owner to answer some of my questions. Ultimately we ended up going with another company due to them having better financing but I wouldn't hesitate to recommend Simmitri to others. When I told them that I was using someone else they didn't try to dissuade me or tell me how bad the other company was. In fact, they knew the sales rep from the other company and told me I was in good hands. Class act all the way with these guys.

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.
