PTC Peak Watts are the REAL-WORLD ranked optimum DC power generated under PVUSA Test Conditions for sunshine and temperature level.
according to everyday conditions, e.g (solar panels). a 250 watt STC component may produce 195 watts in NOCT conditions. Nominal Watts are the standard continuous DC power created in EVERYDAY conditions for sunshine 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 mph
