In my first eight months at SunPower, I provided direct support to customers and dealers, handling inquiries and troubleshooting solar power systems. I then moved to an offline role, managing dealer inquiries via email, coordinating site follow-ups, confirming replacements, and reviewing technician reports. Later, I joined the Product Technical Support Engineering team, where I performed advanced troubleshooting and worked closely with Product Engineers on complex cases. I also expanded my expertise by learning about Tesla and Enphase products and received training in Tesla system installation and commissioning.
