St Supery Estate Vineyards Winery

St. Supéry originally installed a 328.6 kW solar power system in 2015 to lower their energy bills and offset their carbon production. Increasing energy rates prompted the addition of a 177.5 kW solar system designed and installed by SolarCraft, which 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 photovoltaic system addition consists of 473 high-efficiency 375-watt solar panels, producing 220,629 kWh annually. Partially roof mounted, the majority of the solar system add-on is mounted on multiple, custom engineered solar structures over the winery's production area.

"This is an important step in our continuous improvement required for Napa Green recertification. The Napa County permitting took over two years and we are thrilled to see this finally come to fruition." - Emma Swain CEO, St. Supéry Estate Vineyards & Winery.

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.

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.
