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


according to daily problems, e.g (SunGoldPower Solar Kits). a 250 watt STC module may produce 195 watts in NOCT conditions. Nominal Watts are the AVERAGE constant DC power created in day-to-day problems for sunshine and temperature level. NOCT irradiance at 800 W per square meter, ambient temperature level at 68F (20C), solar cell temperature at 113F (45C), wind speed 2 miles per hour


A greater % is much better, however make sure to stabilize that with the price of the panel. A lot of basic solar panels have effectiveness from 14% to 20%. Some greater performance panels can be dual the rate of ordinary performance panels.
