Our Company

The organization was founded as a development company in 2006 under the name Calisolar, with the goal of manufacturing low-cost photovoltaic (PV) solar cells from silicon designed specifically for the solar industry (“solar silicon”) rather than electronic-grade polysilicon. Among the company's founding members is solar energy pioneer Dr. Eicke Weber, Director of the Fraunhofer Institute for Solar Energy Systems ISE.

Supported by venture financing from Hudson Clean Energy Partners, LP, Advanced Technology Ventures and Globespan Capital Partners, the company built its management and engineering teams; in 2009, construction was completed on a 60 MW PV cell production facility, consisting of a vertically integrated ingot, wafer and cell manufacturing line in Sunnyvale, California.
