Andrew L.
Cobalt Power Systems installed a 10 kW Maxeon system with a Tesla Powerwall. The team was incredibly professional and the system has been flawless. Over 20 years of experience really shows.
Rachel S.
We went with Cobalt because of their SunPower Elite status and Tesla Powerwall certification. The installation was smooth, the panels look great, and we have not paid an electric bill since.
Kevin P.
Experienced and reliable company. The Maxeon panels are top quality and the Enphase monitoring is excellent. Installation took three days for our larger commercial system but everything went well.
