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


according to everyday conditions, e.g (solar panels). a 250 watt STC module might generate 195 watts in NOCT conditions. Small Watts are the AVERAGE constant DC power produced in daily conditions for sunshine and temperature. NOCT irradiance at 800 W per square meter, ambient temperature at 68F (20C), solar cell temperature at 113F (45C), wind speed 2 mph


A higher % is better, yet be sure to stabilize that with the expense of the panel. A lot of basic photovoltaic panels have efficiency from 14% to 20%.
