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


according to day-to-day conditions, e.g (solar generators). a 250 watt STC component may create 195 watts in NOCT problems. Nominal Watts are the AVERAGE continual DC power generated in daily problems for sunlight and temperature. NOCT irradiance at 800 W per square meter, ambient temperature level at 68F (20C), solar cell temperature at 113F (45C), wind rate 2 miles per hour
