Project Summary

Cogenra Solar has developed, prototyped and validated the technical performance of an innovative concentrating photovoltaic (CPV)/ thermal co-generation technology and conducted a 80 kW demonstration at the Sonoma Wine Company. The field performance of the system was measured and used to refine economic and financing models and optimization over multiple tariff structures. This project also looked at modifying the co-generation system so that it can support tri-generation of electricity (heating and cooling), expanding the market to include commercial sites that require cooling and lower amounts of hot water. Additionally, Cogenra Solar modified the system to provide energy storage for use during peak demand and coordination with PG&E on grid integration.
