Solar panels promise a lot – a cleaner, cheaper, renewable energy source, harnessed from the abundant rays of the sun. But the technology created to pull in that sun power can only go so far per square foot, depending on the panel.
SolarCity, the sun-powered startup founded by Elon Musk’s cousins Lyndon and Peter Rive, announced today that it has created the world’s most efficient solar panel, with a 22 percent module-level efficiency. Compare that to SunPower’s close rival X-Series panels at 21.5 percent module-level efficiency.
