Napa Valley Winery Solar Panels

Napa Valley Winery Solar Panels

Napa Valley SolarThis solar array, installed in November 2013, had to be carefully fit between a row of closely spaced grape vines and a property line drainage ditch. Equipment access was minimal. The architect, also the owner, used a helical anchor system for support which mitigated the need for pumping concrete. Wind load controlled the support design, which was determined by the geotechnical expertise of The Sutton Group. Pipe pipe columns welded to the helical piers, raised the panels 8 feet off the ground to create a “wing” 160 feet long. Our firm began work on this low-lying, expansive clay site in 1999 with a geotechnical investigation for the main residence. The vineyard was established in 2002 and their first harvest was in 2005. We assisted with engineering for the secondary residential building (2300 sf) in 2003, built on a passively reinforced, ribbed raft foundation. From 2009 through 2011, we assisted with engineering and construction of a 3000 square foot barn, with a wine oriented functional lower level (2000 sf) and a 1000 sf guest unit upstairs. This ICF-walled building is supported on a post tensioned, “waffle box” coffered slab.
