Panasonic claims to have toppled a world record for module efficiency announced only days ago by SolarCity and will be demonstrating the new module at next week’s Solar Energy UK exhibition organised by PV Tech's publisher, Solar Media. Panasonic said the new record built on cell-level efficiencies of 25.6% recorded last year. “The new panel efficiency record demonstrates once again Panasonic’s proven leadership in photovoltaics and our ongoing commitment to move the needle in advanced solar technology,” said Daniel Roca, senior business developer at Panasonic Eco Solutions Europe.
