2 X 2100 gal. for Kendall-Jackson
Kendall-Jackson decided on solar cogeneration. Wine operations require large amounts of hot water and electricity, and solar cogeneration provides both of these resources, cleanly and sustainably, and in one product. In addition to the unique benefit of dual energy production, Kendall-Jackson chose solar cogeneration for its quick payback time, simple integration into existing infrastructure and unparalleled environmental benefits.
The facility’s energy use called for 96 Cogenra PVT (photovoltaic-thermal) modules and two 2100 gal. Haase Energy Tanks to supply the building with approximately 1.4 million gallons of hot water annually. Working with SunWaterSolar, a leader in solar thermal technologies, Cogenra installed the 241kW turn-key system over roughly 9,000 square feet on the roof of the Kittyhawk plant—the largest solar cogeneration rooftop array to date.
About a month after construction began, the solar cogeneration system was completed and is currently generating enough solar hot water to wash seven 15,000 gallon tanks and one 100,000 gallon tank daily. The system also feeds electricity to the building’s grid to power lighting and cooling systems. The Cogenra array combines PVT panels, fully integrated hydronics, tracking controls and inverter in one system. Remote monitoring and performance diagnostics provide Kendall-Jackson with instant insight into system performance and the environmental impacts of the solar cogeneration system around the clock.
