These ratings can be used to compare panels. Attempt to avoid a panel with high STC or factory-rating, however a reduced NOCT or everyday score, about an additional panel. as noted by the manufacturer, e.g. 250 watt photovoltaic panel is qualified of creating maximum 250 watt constantly under ideal Conventional Test Problems.


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


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


A higher % is better, however make sure to stabilize that with the expense of the panel. A lot of conventional photovoltaic panels have effectiveness from 14% to 20%. Some greater effectiveness panels can be dual the cost of ordinary effectiveness panels.
