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 module might create optimal 225 watts in PTC real-world problems. PTC Peak Watts are the REAL-WORLD ranked MAXIMUM DC power created under PVUSA Test Problems for sunshine and temperature.


according to daily problems, e.g (power stations). a 250 watt STC component might produce 195 watts in NOCT problems. Small Watts are the AVERAGE continual DC power created in daily problems for sunshine and temperature level. NOCT irradiance at 800 W per square meter, ambient temperature at 68F (20C), solar battery temperature level at 113F (45C), wind rate 2 mph


A higher % is much better, but be certain to stabilize that with the cost of the panel. Most basic solar panels have performance from 14% to 20%.
