SolarCity unveils world’s most efficient rooftop solar panel

SolarCity built the world’s most efficient rooftop solar panel, with a module efficiency exceeding 22%. The new panel is the same size as standard efficiency solar panels, but produces 30-40% more power.

The new SolarCity panel generates more power per square foot and harvests more energy over a year than any other rooftop panel in production.

SolarCity will begin producing the first modules in small quantities this month at its 100 MW pilot facility, but the majority of the new solar panels will ultimately be produced at SolarCity’s 1 GW facility in Buffalo, New York. SolarCity expects to be producing between 9,000 – 10,000 solar panels each day with similar efficiency when the Buffalo facility reaches full capacity.

The panel also performs better than other modules in high temperatures, which allows it to produce even more energy on an annual basis than other solar panels of comparable size.

The company initially expects to install the new, record-setting solar panel on rooftops and carports for homes, businesses, schools and other organizations, but it will also be excellent for utility-scale solar fields and other large-scale, ground level installations.
