In the fifth award announcement regarding a solar project or company this week, the US Department of Energy said it has offered a conditional loan guarantee commitment of $150 million to 1366 Technologies to help the Lexington, MA-based silicon PV innovator to scale and expand manufacturing of its DirectWafer technology. The company plans to use the funds to bring its first plant, a 20MW facility in Massachusetts, online in 2013, and then to begin construction on a second 1GW plant that same year in an as-yet undetermined US location.
