Tori Clifford

Tori coordinates public relations, grassroots marketing campaigns, and co-marketing initiatives with our partners across the Americas. With solar industry experience both upstream and downstream, Tori is as comfortable coaching a homeowner through the solar adoption process as she is pitching the merits of fluoropolymer backsheets. Hailing from San Francisco, California, Tori is passionate about making solar energy approachable, accessible, and affordable for all.
