PTC Top Watts are the REAL-WORLD ranked optimum DC power created under PVUSA Test Problems for sunshine and temperature level.
according to daily problems, e.g (solar panels). a 250 watt STC component may create 195 watts in NOCT problems. Small Watts are the AVERAGE constant DC power produced in day-to-day conditions for sunshine and temperature level. NOCT irradiance at 800 W per square meter, ambient temperature at 68F (20C), solar cell temperature level at 113F (45C), wind speed 2 miles per hour
