PTC Height Watts are the REAL-WORLD rated optimum DC power generated under PVUSA Examination Conditions for sunlight and temperature level.
according to everyday conditions, e.g (solar kits). a 250 watt STC module may produce 195 watts in NOCT problems. Nominal Watts are the standard constant DC power generated in daily conditions for sunshine and temperature. NOCT irradiance at 800 W per square meter, ambient temperature level at 68F (20C), solar battery temperature level at 113F (45C), wind speed 2 miles per hour
