Cobalt Power Systems

Recently, my 20-year-old solar system faded into non-action. Through my neighborhood list serve, I received a referral to Cobalt Power Systems. Following an inspection by Alex Harrison, the lead engineer, I agreed it was time to put in a new system. The old panels were dismantled and by the end of May my new system was in place and up and running. In addition to Alex, who led the project, I met the team of three, led by Mikey, who completed the installation. For anyone either new to solar systems or looking to replace an old one, I highly recommend Cobalt Power Systems for three reasons. (1) Time will tell, but I would say product quality is excellent. (2) Alex provided me with accurate and reasonable cost estimates, so I know what to expect. He also offered payment options. (3) Everyone on the team was a good communicator--ready to answer my questions and accommodate my travel schedules. The funniest thing happened on the first installation date--it rained! The team cheerfully used the time to help me clear out my garage, put the new panels in my garage and organize them so they are ready to use. Everything was completed in less than three months, despite my travel.

Since writing my original review, Cobalt has reengaged with their top leaders, apologized for the shoddy service, and made things right with some additional products and services at no cost. I appreciated them taking the feedback seriously and feel like they've more than made up for the poor service.

Thank you Cobalt Power for providing excellent service! After my installation, I was placed in the hands of Alex H., a Field Technician Manager. He acted as the "closing pitcher"--responsive, communicative, and dedicated to seeing the final details through to completion.

A final update: We are nearing the end of our 'solar journey' after a few final hiccups, but I think I can stick a fork in this review. Cobalt managed to install the panels and batteries in a single day (12/13), hitting the critical year-end tax credit deadline. While I was told they were juggling 14 jobs that day, the 'all-hands-on-deck' effort was impressive. However, I wasn't told until afterward that it would take another 5-7 weeks for PG&E to replace the meter collar (the 'BUS install'). Since this is a prerequisite for PowerWall 3 systems to feed power back into the panel, my system sat in standby mode for over a month waiting for a five-minute PG&E visit. While the utility's timeline is outside Cobalt's control, it did take the wind out of my sails, so to speak. Regarding the pre-install process, the experience shifted once I voiced 'strong concerns' via a Yelp review and my sales rep. Following that, I received true white-glove service; dates stopped slipping, and check-ins became frequent. This proved critical when my PowerWall 3 failed and required an RMA just before the PG&E visit. To Cobalt's credit, they handled the replacement swiftly, finishing with literally hours t

TL/DR-Stay far, far away. We evaluated 3 companies for a solar project. Decided to use Cobalt in July 2025 and we regret the decision greatly. We were told by our salesperson that our job would start 2-3 months after signing the contract. The contract itself estimated that work would commence September 8th and finish on November 8th, in plenty of time for the expiring tax incentives. Permits were issued by the end of August and things spiraled from there. I received a call from the PM in early October (3 weeks after the estimated start date) indicating that work would start in 2-3 weeks. Come October 28th, nothing had been communicated. I reached out to the PM only to learn that she had left the company and no replacement was provided, leaving us in a black hole. The salesperson and GM (who has responded to many reviews on this site) were unresponsive to an email that I left asking for an update. It took me reaching out to the person who recommended Cobalt to get things back on track via that salesperson.
