When we reported on SolarCity’s record panel claim late last year, it boasted an oddly precise 22.04 percent module-level efficiency as measured by the Renewable Energy Test Center (not a designated test facility). The silicon-based bifacial PV cell combines n-type substrates, copper electrodes, thin-film passivation layers, and a tunneling oxide layer that yields high conversion efficiencies. At the time, SolarCity claimed that its module would be "the highest-volume solar panel manufactured in the Western Hemisphere."

The record panel was manufactured on the company's 100-megawatt pilot production line -- its Buffalo factory won't be at full production until 2017, with a target of 10,000 solar panels per day at full capacity.
