SolarCity dethrones SunPower with new most efficient rooftop panels


Feb 9, 2012
Huh... the first article states that SolarCity is able to produce the panels this month, and Panasonic is able to do so only mid-to-end 2016. Meanwhile the second article stated that Panasonics prototype "can be immediately scaled into volume production."
Kinda makes a huge difference whether there is a year between the two releases or not. Either way, good to see that competition in this segment is alive and well.
