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

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


A greater % is much better, but make sure to stabilize that with the price of the panel. The majority of typical photovoltaic panels have efficiency from 14% to 20%.
