Cogenra’s first technology release was a low concentration system for solar cogeneration of PV-based electricity and heat in 2010. Subsequent generations of this product were successfully deployed across 40 other sites in various geographies and diverse climates.
Customers include Facebook, Kendall Jackson Wines, Sonoma Wine Company, U.S. Department of Defense, Univ. of Arizona, Intercontinental hotel, Tucson Medical Center, among others.
The most recent generation of this low concentration PV system, called the T14, was certified, installed and commissioned at the University of Arizona’s SolarZone among other installations. This SolarZone project with a capacity of 1.1MW was financed and owned by Washington Gas Energy Systems.
The T14 drew on Cogenra’s deep heritage in solar cogeneration systems to combine high-efficiency silicon PV cells on an aluminum substrate which formed the receiver of the T14 system. This patent pending interconnection technology developed by Cogenra, called the Dense Cell Interconnect (DCI) improved the performance of the T14 system by up to 40% compared to previous generations.
Cogenra is further developing the DCI technology for concentrating and conventional PV applications. Leveraging expertise in concentrating tracking systems, Cogenra is developing a low-cost single-axis tracker for conventional PV modules.
