Offline Solar Electric
About Offline Solar Electric
Offline Solar Electric is a locally owned and operated solar installation company based in Mariposa, California, serving Mariposa and Eastern Madera Counties. Founded in 1982 by Don and Cynthia Loweburg, the company has installed over 1,000 on-grid and off-grid solar systems throughout the Sierra foothills and Central Valley. Current owners Brooke and Karen Hanner continue the company's tradition of custom-designed solar solutions tailored to each customer's specific property and energy goals. Offline Solar offers three primary services: grid-tied solar installations, which provide the financial benefits of solar while maintaining grid connectivity; off-grid solar systems for customers without electrical service access or those seeking full energy independence; and battery-backup systems configurable to power a single room or an entire home, with or without accompanying solar panels. The company emphasizes building systems that customers own outright rather than lease, and states that its installations provide decades of clean, secure energy while increasing property value. Owner Brooke Hanner brings more than 30 years of electrical industry experience and personally lives in an off-grid, sun-powered home he designed and built in Mariposa County. Offline Solar has been a pioneer in Central California solar since its founding over four decades ago.
