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!

Throughout the process, they were punctual, hardworking, and handled all of the necessary approvals for San Francisco, which gave us real peace of mind. Steve and the team were outstanding--patient, responsive, and clear in their explanations of the system. They installed 22 panels with microinverters, plus a Franklin battery and Enphase monitoring, and everything has been working smoothly since day one. The best proof came just a week later, when a full-day neighborhood power outage didn't affect us at all--we had seamless backup power the entire time. The whole experience has been a solid success, and we're very happy to recommend Solar Pro Energy to anyone considering solar.

We were referred to Collin Lang through an extremely knowledgeable sales person from another solar provider whose systems would not meet our needs. Collin provided great detail on the solar system being considered and outlined the benefits, capabilities and warranties accurately and thoroughly. I am an extremely demanding customer requiring complete details and expect to have my questions answered thoroughly and without ambiguity. This is where Collin really impressed us. He spent many hours answering my questions over multiple meetings and discussions. We decided that Enphase systems with whole house backup using batteries was the best option for our needs. We were so impressed with Collin that we decided to put solar on both of our homes. Unfortunately, one of the homes required a new roof before solar could be installed. Collin helped us find a roofing company after soliciting several quotes. The company he recommended promptly installed the roof within a week and a half and passed all inspections without issue. The solar was then installed shortly after and operational within a month after acquiring Permission To Operate from PG&E. Both homes are producing enough energy to run the homes as well as generating PG&E credits to spare. I would also like to add that Collin has always made himself available for any questions or assistance during and after the installation without any hesitation. He even recently reached out to us to see if we needed any assistance with the mobile app that allows us to monitor our Enphase systems. I would highly recommend Collin Lang to anyone pursuing a solar option for their home or business. David and Nancy

I contacted Sunwise Solar Solutions in the third quarter of 2025.

So I had just been burned the end of the year that cost me 20K in extra taxes. I was mistrustful about the entire industry at that point, but I wanted solar and the tax credits were to be eliminated end of 2025. That's when I called Sunwise and met Ali. He stayed in contact with me, and then came to the house to do an evaluation. From the beginning there was something more human about his approach than my previous experience. He is professional, knowledgable, and an excellent customer service representative. After signing a proposal that was about the same amount of money as the previous one in 2024, we started figuring out delivery and installation. Because the tax credits were expiring, all solar companies had a rush of business. As with any project, there were a few glitches along the way. Ali was always available and able to smooth things to keep the project moving forward. Chris came with his team to install the panels and batteries. They knew what they were doing. I have gone into my attic months later during a big rain storm and there are no roof leaks. After the installation, there was a glitch with the batteries and I still remember Chris and Sam working in the rain, on the phone with the manufacturer until the system was working correctly. Also the previous solar company insisted(at the last minute) that I needed a sub panel for an extra 5K. Sunwise figured out how to install with no extra expense. Ali, Chris, and Sam are owners of the company and that's who I dealt with. All professionals. I can still write any of them and they respond quickly Even though my experience with the previous solar company was awful, things worked out best for me.
