RUN

Sunrun Inc.

A US company that puts solar panels and home battery systems on rooftops, letting homeowners power their houses with sunshine through its BrightBox storage service and pay-as-you-go plans rather than buying panels outright. Founded in 2007 in a San Francisco attic by Lynn Jurich and Ed Fenster, classmates at Stanford's business school, it grew into one of the nation's largest residential solar providers. The name "Sunrun" evokes the sun's daily journey across the sky, capturing the steady rhythm of panels soaking up energy from dawn to dusk.
