PowerLight Installs Large Solar Arrays in California

Two Sonoma County vineyards are now relying on sunshine for more than its propensity to ripen grapes. A 766-kilowatt system built by PowerLight Corporation and covering 60,000 square feet of roof space atop Rodney Strong Vineyard's barrelhouse recently began providing a significant portion of the winery's power needs. The system went online earlier this year, and PowerLight is in the process of installing a 457-kilowatt system for St. Francis Winery in Santa Rosa to be completed in May. Vineyards may be particularly appropriate for solar power applications due to their customary flat-roofed storage areas and sunny locations. See PowerLight's press releases on the installations.

PowerLight is also responsible for installing the largest city-owned solar installation in the country, a similar 60,000 square-foot flatroof installation on San Francisico's Moscone Center. Mayor Gavin Newsome dedicated the 675-kilowatt system on March 18. In addition to the array, the Moscone Center installed new building controls and energy efficient lighting. According to PowerLight, the solar power and the energy-efficiency measures together will make available more than five million kilowatt-hours annually. See the press release.
