STC irradiance at 1000 W per square meter, cell temperature at 77F (25C), air mass AM 1.5. according to PVUSA examination conditions, e.g. a 250 watt STC module might generate maximum 225 watts in PTC real-world problems. PTC Peak Watts are the REAL-WORLD ranked MAXIMUM DC power produced under PVUSA Test Problems for sunshine and temperature.


according to daily conditions, e.g (solar inverters). a 250 watt STC module might produce 195 watts in NOCT problems. Nominal Watts are the standard continuous DC power created in EVERYDAY problems for sunlight and temperature level. NOCT irradiance at 800 W per square meter, ambient temperature at 68F (20C), solar battery temperature level at 113F (45C), wind speed 2 miles per hour
