SolarCity announces ‘world’s most efficient’ rooftop solar panel

By eeNews Europe

SolarCity claims the solar panel – which has a module efficiency exceeding 22% – generates more power per square foot and harvests more energy over a year than any other rooftop panel in production. The company says it 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 the company’s 100-MW pilot facility. However the majority of the new solar panels will ultimately be produced at the company’s 1-GW facility in Buffalo, New York. SolarCity expects to be producing between 9,000 to 10,000 solar panels each day with similar efficiency when the Buffalo facility reaches full capacity.

SolarCity’s panel was measured with 22.04% 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% more power.

SolarCity’s panel is also claimed to perform 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 solar panel on rooftops and carports for homes, businesses, schools and other organizations, but it will also be suitable for utility-scale solar fields and other large-scale, ground level installations.
