St. Supéry
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.

Congratulations to Napa Green Certified @cliffamily for winning the RISE Leadership Award for Supply Chain & Waste Management Excellence!
Clif Family attended our first conference & committed to reducing their bottle weight and waste. They set upon an inspiring journey to change their packaging based on their outdoors loving and mountaineering inspired founders. They were able to..
• lighten the weight of a case of their wine by almost 8 lbs!
• reduce their carbon output by 42 metric tons!
• institute fully recyclable, bio based shippers that keep wine cool!
• eliminate all foils!
• eliminate all plastic & metal moving fully to renewable cork enclosures!
Their customers responded with absolute enthusiasm.
“This story is not just about wine packaging or supply chain decisions. It’s about how we do business. It’s leading with values. It’s about remembering that the best way to climb higher.. is to carry less.” - Sarah Richmond, Clif Family Winery.

Napa Green’s vineyard team is trained to develop regenerative, whole-farm Carbon Farm Plans (CFPs). These plans review all of the current beneficial practices that are increasing soil and ecosystem health and storing carbon, and identify additional opportunities to regenerate the soil and vineyard ecosystem and simultaneously maximize carbon capture in a given property. Each vineyard’s goal is to become carbon neutral (or negative) and increase the resilience of vineyards, businesses, and our community.

Forests are not only our largest terrestrial carbon sink, they are also home to 80% of the world’s on-land diversity. We need healthy forests, which means a balanced density of native trees and plants. Healthy forests experience lower intensity fires with less tree mortality, meaning higher carbon retention and ecosystem function.
