    My system working to power my home without the need to pull from the grid. Screw PG&E!
    Jen L.

    Building a custom home in the Bay Area taught me a lot. The city of Hayward refused to release my electric meter until after solar was installed. I contacted multiple companies and after getting pricing and information I decided to move forward with Nabu. I liked that they do not work on commission which allowed their price to be $10k lower than the others for the same products. The most important part to me was the service. I needed everything ASAP to keep construction on track and they jumped through so many hoops and maintained communication. I was rushing to get the system installed before the end of the year to get the tax credit before it ended. Nabu had their team at my house on New Years Eve to ensure we met the deadline. They even contacted me after to make sure everything went according to plan and we DID get the tax credit which was $15k! I have a black metal roof and Nabu even painted the conduit pipes black instead of leaving them silver to ensure it looked amazing. I highly recommend Nabu!

    5 stars, and I'd give more if I could. I came to Nabu Energy on a friend's recommendation for what I thought would be a straightforward solar panel reinstall. Nabu took my project from start to finish and turned a complicated situation into a seamless experience. The wrinkle: my original inverters had been discontinued, which meant a standard reinstall wasn't an option. Rather than pushing me toward a full replacement, The engineering team at Nabu found a way to keep my existing panels -- which were still in great shape -- and upgrade the system to dual Tesla Powerwalls. They managed the design approval with PG&E and handled all the coordination I didn't want to deal with. Going into this, Powerwalls weren't on my radar. The engineering team made a clear, honest case for why they made sense long-term, and once I ran the numbers with federal incentives factored in, it was hard to argue. I ended up with a significantly better system than I started with and didn't blow my budget to get there. The installation quality is excellent -- clean, professional, and exactly what you'd want. Check out the photo I attached. If you need solar work done and want someone who will actually think through your situation, Go with Nabu

    Had my solar system: solar + battery installed in 2025. Overall quite satisfied with Nabu's services. They are local companies and I like to work with local installers. Price: Nabu's offer has better value vs the other 2 good-review local installers I spoke with. Although slightly higher than a larger regional brand, I still prefer local installers. Services: installation/permit process was overall smooth. Project manager kept me updated. And they were quite reasonable with all my personal, detailed requests during installation. I did have some hiccups on installation appointment and needed reschedule. I called Bhushan, he always took care of it. Product: solar/rec panel is strong in my area and tesla powerwall3 performs as expected. No complaints so far. My tip: consider getting 2 power wall3 batteries if you have the budget and the math of value return works out. My solar often max out battery in daytime and has to export quite some to pg&e. Know-how: from my experience, the owner and sales: Bhushan is quite knowledgeable on their product and offering, this is quite distinctive from all other companies I spoke with. Bhushan answered all my technical questions and concerns, with good faith and honesty. For reference, my installation time line: Contract signed on feb 1st, system online on May 15.

    Highlight Solar

    (247 reviews)

    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.

    Clean Solar

    (477 reviews)

    North San Jose

    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!

    Hello everyone, I…read morehad a great experience with Solar Sesame. I had my system installed in December 2025 and wanted to wait a bit to see how SS and GoodLeap handle follow-up on the project, Closeout issues, and customer service follow-up. Since my December 2025 installation and the January 2026 activation with PG&E, I have been more than happy with their service. I had put off getting solar for a while (bad decision on my part), so when the $1,100 PG&E bill came in last summer, I knew it was time for a change. Solar Sesame's pricing consultation was pleasant and informative. I had done plenty of research, so I knew my stuff, and being in Construction helped as well. Both their Sales Rep and Installation Lead were informed and knew their stuff. My Project Submittal documents to the City of Danville were professionally done. The building permit was obtained quickly, and the installation was completed within a few days. We did have an initial hiccup with the materials delivery; it arrived too early, but SS had it picked up and redelivered the following week. All in all, a solid performance from Solar Sesame!
