Claim: Cell size: 62.5" x 32.5" = 2031.3 sq in = 1.31 sq m
2800 W / 1.31 sq m = 2137.4 W/m^2 > (1) Standard Test Conditions (STC) of 1000 Watts per square meter > irradiance, air mass of 1.5, 25oC cell temperature used in lab testing and > rating of photovoltaic modules. Performance: Pout/Pin => (2137.4 W/m^2) / (1000 W/m^2) => 214 % eff. Remarkable!!
