Cogenra Solar has installed the United States’ largest rooftop solar cogeneration system to date at Kendall-Jackson’s Kittyhawk winery in Windsor, California.

The project, which expands on Kendall-Jackson’s existing energy and water conservation initiatives, is a 96-module, 241kW hybrid solar photovoltaic (PV) and thermal array that is expected to save approximately $30,000 in annual energy costs.

Smart Meters reports that the power generated will be used to supply solar hot water and electricity to power the winery’s tank and bottle washing operations. The solar cogeneration system provides up to 60 per cent of the building’s hot water needs, with the electricity powering lighting and cooling.
