STC irradiance at 1000 W per square meter, cell temperature level at 77F (25C), air mass AM 1.5. according to PVUSA test problems, e.g. a 250 watt STC component may produce optimal 225 watts in PTC real-world problems. PTC Height Watts are the REAL-WORLD ranked MAXIMUM DC power created under PVUSA Test Problems for sunlight and temperature level.


according to daily conditions, e.g (SunGoldPower Solar Kits). a 250 watt STC module might create 195 watts in NOCT problems. Nominal Watts are the AVERAGE continual DC power generated in EVERYDAY problems for sunlight and temperature. NOCT irradiance at 800 W per square meter, ambient temperature level at 68F (20C), solar battery temperature level at 113F (45C), wind speed 2 mph


A greater % is better, but be sure to stabilize that with the expense of the panel. The majority of common photovoltaic panels have efficiency from 14% to 20%.
