| Wine Service Co-Operative dedicates two solar arrays  The Wine Service Co-Operative dedicated a 428 kW solar electric system for their Napa Valley facilities, furnished by PowerLight Corporation. Comprised of two solar electric systems, 197 kW and 231 kW, the projects are installed atop the Wine Co-Op’s St. Helena and South Napa facilities. These solar arrays will generate enough electricity during the day to power over 400 homes, and combined with energy efficiency measures, provide up to 100% of the facilities annual energy needs, substantially reducing operating costs. The PowerLight tilted solar roof system at the Wine Service Co-Op features modules with a 10-degree tilt to maximize exposure to Napa’s abundant sunshine.The lightweight, photovoltaic roofing assembly generates clean solar electricity, protects the roof from the damaging effects of weather and UV radiation, and is installed without penetrating the roof surface. The solar arrays, which consist of 2,085 high efficiency solar modules manufactured by Sharp, cover a total of 38,000 square feet. These solar arrays leverage an unused asset—the facilities’ roofs—to generate clean power and reduce operating costs. When combined with lighting upgrades, the solar generation system will substantially eliminate the facilities annual electricity requirements. Over the next 30 years, this solar electric system will spare the environment from tons of polluting emissions, such as CO2, NOx, and SO2, that contribute to smog, acid rain and global climate change. In addition to solar generation, PowerLight deployed energy-saving lighting upgrades at the Napa warehouse using high efficiency, high output linear fluorescent technology. Additional energy efficiency measures performed by the Wine Co-Op included additional insulation in the roofing system, and the replacement of air conditioning package units. write your comments about the article :: © 2005 Construction News :: home page |
