New module that generates more power per square foot than any rooftop solar panel in production will also be the highest-volume solar panel manufactured in the U.S.
Oct 02, 2015

SAN MATEO, Calif. – SolarCity (NASDAQ: SCTY) has built the world’s most efficient rooftop solar panel, with a module efficiency exceeding 22 percent.  The new SolarCity panel generates more power per square foot and harvests more energy over a year than any other rooftop panel in production, and will be the highest volume solar panel manufactured in the Western Hemisphere.

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.

SolarCity’s panel was measured with 22.04 percent module-level efficiency by Renewable Energy Test Center, a third-party certification testing provider for photovoltaic and renewable energy products. SolarCity’s new panel—created via a proprietary process that significantly reduces the manufacturing cost relative to other high-efficiency technologies—is the same size as standard efficiency solar panels, but produces 30-40 percent more power. SolarCity’s 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.

SolarCity 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.
