We had an excellent experience with Nabu Energy and would highly recommend them. Their customer…read moreservice and project management were outstanding from beginning to end. They guided us through every stage of the process, communicated clearly, and made what could have been a complicated project feel smooth and straightforward. Their pricing was competitive, and the quality of both the planning and installation was excellent. Kishan and Bushan were especially great to work with--responsive, knowledgeable, and genuinely committed to making sure everything went well. Nabu installed approximately 12 kW of solar capacity along with two Tesla Powerwall 3 units for our fully electric home. The system has been working beautifully, with all of our household electricity flowing through the Nabu-installed system. We are extremely happy with the finished project and grateful for how easy the Nabu team made the entire experience. Five stars without hesitation.

We had solar installed by Nabu Energy in late 2025 to take advantage of the 30% Federal tax credit…read more After getting quotes from several companies, Nabu Energy was clearly the best. The cost for both the 10.1 kW and 12.4 kW systems with two powerwalls each for two properties made complete sense even before applying the 30% tax credit. The tax credit is just a nice icing on the cake. The team was professional. The installation went smoothly. We've already seen the savings and long-term benefits. Can you say all you can run AC in the summer? If you're shopping for solar and want excellent value without any of the usual markups, we highly recommend Nabu. I'm happy to share I referred brother to install solar with Nabu. He was very reluctant, but eventually came around. He got his 10.1 kW system with two powerwalls installed earlier this year so he missed out on the 30% Federal tax credit. However, he's still very happy he did it. You simply cannot go wrong with Nabu Energy and its amazing pricing.

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.

Wow, I cannot say enough good things about Ryan and his team! I hired them to remove our 69 solar…read morepanels and reinstall them after a re-roofing of our home. It's a nerve wracking process but Ryan gave me reassurance things would go well. Upon Ryan's recommendation, we also decided to replace the solar panel racking system installed by Sunrun because we were plagued with roof leaks due to improper sealing of their footings. Ryan and the Northstar team were absolute champs at removing and reinstalling the new system for us. Everyone we dealt with was so professional, kind and easy going. The work was beautifully done and based on all the photos and detail provided by Ryan I am confident we will be safe from leaks going forward. He also had to coordinate the reinstall with our roofer and everyone handled it so well. I 100% recommend Northstar and the team for this task, and also wouldn't hesitate to hire them for roofing based on their strong work ethic and product with our solar project. The price was fair and in line with other quotes I'd received. A couple of questions unrelated to this particular job have come up and Ryan has gone above and beyond to help me out by providing his professional input. So happy with these guys. Thank you!

Once again Sky Power has provided excellent help. All the extremely heavy rain lately has caused a…read moreproblem with my roof. While the problem was not with the Sky Power installation the preceding removed (by others) installation of pool solar had left some poorly installed and removed hold down bolts which the sealant began to fail. Sky Power technicians removed some of the solar electric panels and discovered and repaired the problems from the long removed pool solar panels. I am very greatly thankful for the prompt service by Tilmo and Anthony.

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!!

When my SolarEdge inverter failed, my solar panels stopped producing power. I reached out to Solar…read moreService Call, and during our initial conversation, they promptly identified that a replacement inverter was required. They took the initiative to contact SolarEdge on my behalf and successfully secured a replacement unit under my existing warranty at no cost. They informed me they would follow up once the new inverter arrived. Shortly thereafter, I received a message confirming its arrival and offering to schedule the installation. They were flexible and worked within my availability, which I found very accommodating. The technician who arrived was professional and respectful. Since my car was parked next to the inverter, he asked if I could move it so he would not accidentally damage it during the work. That level of thoughtfulness stood out to me. He completed the replacement efficiently, verified that everything was functioning correctly, and gave me time to ask any questions. The following day, I received an invoice for the labor, which was competitive. I believe the cost was considerably lower than what many other solar companies would charge for a similar service. Overall, I am completely satisfied with both the quality of work and the level of service. If your solar system is not functioning, I recommend reaching out to Solar Service Call. Even if you are considering calling your original installer, it may be worthwhile to see what Solar Service Call can offer. You could receive excellent service at a more competitive price.

Jeff reached out and helped me troubleshoot the problem first before we decided to have them come out. David the technician ended up coming out and found a really serious issue that could have been disastrous had it not been fixed. The communication and quality of the service overall are what really stood out. Between Marlene keeping me informed about the schedule and following up the day after to make sure things were operational to David's work to fix the issue and his communication afterwards and Jeff staying in touch the whole time, it was a great experience. Highly recommend East Bay Power!

The product is good, the process left us wanting…read more Eric, David, Jose and the crew did an excellent job. My frustration was with the post installation process. I got answers from Darlene that did not make sense. Sometimes her computer was down other times her phone was down. Sometimes she would call to give me a message only to realize that she had called the wrong customer. Did not enjoy working with her. Finally, Kara engaged and we got the Permission to Operate about two months after the install. Supposedly Jeff (the Business Owner) is no longer with the company and has gone back East, so not sure who is leading their future efforts. For future customers: hang on to a portion of the payment till the Permission to Operate is received not just the installation.

Synergy owner Eric Piekarczyk recently demonstrated proactive ethics that are hard to find. The…read morecompany failed to assist in diagnosing a component known as a Gateway in my pv system. Which resulted in prolonged failed solar generation. Eric, rather than blaming the problem on anything or on me offered 2 extra panels in compensation.
