Winery Solar Electric Installation Project Profile

solar panelsNovato and Sonoma based SolarCraft designed and installed a 400 kW solar electric power installation at The Duckhorn Portfolio’s Migration Winery at 1451 Stanly Lane in the beautiful Carneros region of Napa Valley.  This large solar power system demonstrates Duckhorn’s commitment to the environmental sustainability of its operations, benefitting their surrounding communities and their bottom line.

The winery was purchased with an existing, aging solar system. Aiming to improve sustainability of the facility and increase the efficiency and production of the solar, the old panels were removed and replaced with state-of-the-art high-efficiency solar PV panels for increased offset of their energy usage. An innovative ‘critter guard’ was also installed around the entire solar array to prevent birds and animals from nesting under the solar panels in this beautiful riverside facility.

The SolarCraft PV system is projected to produce 612,630 kWh annually, providing approximately 75% of Migration’s electricity needs for the winery’s 60,000-square-foot building.  Through Net Energy Metering, or NEM, the winery is able to sell excess solar power back to the utility, granting them additional income and reducing the strain on the local power grid. With a 25-year performance warranty on the major system components, this system will be saving Migration hundreds of thousands of dollars in operating costs for decades to come.

The annual clean energy production will offset 434 metric tons of carbon dioxide that would otherwise be emitted by fossil-fuel based utility power. This impact is equivalent to removing the air pollution produced by over 1 million miles of driving annually or the pollutants removed by 514 acres of trees. Over the life of the system, over 3.2 million gallons of water use will be avoided that would otherwise be used for fossil fuel energy production.
