CSLB License # 979146 Meet Our Team Hans Rosenberger, President / Chief Engineer Altadena Energy & Solar was founded by Hans Rosenberger out of a belief that good engineering and financing are important for the development of environmentally friendly solar energy systems and buildings. There is a strong demand for energy savings and ‘green power,’ but too few practitioners who understand both engineering and finance. Hans majored in Physics at Goshen College, and completed his Masters of Electrical Engineering at Penn State. He pursued a career in radiometry-based remote sensing at NASA’s Jet Propulsion Lab (JPL) in Pasadena, CA, where he was staff engineer for 5 years in ground- and air-based microwave systems. His work included field engineering at communication ground stations in California and Spain and airborne experiment campaigns in Florida and Sweden. He left JPL to pursue further aspirations in business and completed his MBA at USC’s Marshall School of Business. During this time he pursued internships focusing on electrical efficiency and demand management for the frozen food warehouse industry in Delaware, and wind energy finance in Tehachapi, CA. After his MBA, he started a property partnership in Berlin, Germany, to test the theory that there was unmet demand for green-oriented real estate development. The real estate work led to the founding of Altadena Energy & Solar, and its partner firm in Germany, RSF Solar, with a focus on technically sophisticated solar and energy efficiency solutions for residential and commercial clients. Hans is an active member of Pasadena Rotary Club; a taskforce member of Senator Carol Liu's Green 21 initiative; and a member of the Pasadena Mennonite Church.
