Napa Valley Winery Harvests the Sun for Sustainability & Savings
Novato and Sonoma based SolarCraft, a leading North Bay clean energy provider for over 35 years, recently completed the design and installation of a 177.5 kW DC solar electric system addition at St. Supéry Estate Vineyards & Winery in Rutherford, CA.
St. Supéry originally installed a 328.6 kW system in 2015 and with these additional panels, the winery has expanded its solar productivity to further reduce their carbon footprint and increase their utility savings even more. The 177.5 kW addition combined with the existing system brings St. Supéry’s solar production to 506.1 kW offsetting nearly 100% of the winery’s energy bills.
The solar power system addition consists of 473 high-efficiency 375-watt solar panels, producing 220,629 kWh annually. Partially roof mounted, the majority of the photovoltaic system add-on is mounted on multiple, custom engineered solar structures over the winery’s production area.
Environmental stewardship is incredibly important at St. Supéry, a winery that is certified Napa Green for both their Land (since 2008) and Winery (since 2012). They strive each day to “walk the walk” in the vineyards, in the cellar and in business practices. “This is an important step in our continuous improvement required for Napa Green recertification. Napa County permitting took over two years and we are thrilled to see this finally come to fruition,” says St. Supéry CEO Emma Swain.
As a 100% estate winery, St. Supéry has complete control over how their grapes are grown and how their wine is made from harvest through bottling. Through their commitment to sustainable winery and farming operations, they are protecting the land and environment for future generations.
Over 156 metric tons of carbon dioxide will be eliminated during the life of the solar power system addition. This impact is equivalent to removing air pollution produced by over 387,000 miles of driving annually or the pollutants removed by 204 acres of trees in one year.
