SolarCity bragged of a module efficiency exceeding approximately 22 per cent, however Panasonic’s Eco Solutions division has now announced that their new prototype solar panel is said to sit at 22.

SolarCity has recently created the world’s most efficient rooftop solar panel that includes a 22 per cent conversion efficiency. The sun-powered startup that was founded by Lyndon and Peter Rive (Elon Musk‘s cousins), SolarCity, announced their construction last week.
