A San Jose company, SunPower, has won the contract to build solar panels for the company's North Carolina datacenter, a filing with the state's Utilities Commission reveals. "Each of the photovoltaic installations will consist of multiple SunPower E20 435-watt photovoltaic modules on ground-mounted single axis tracking systems," the document reads. The solar farm is being built in phases, and could be ready to supply power in October.
