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


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


A higher % is much better, yet make certain to balance that with the cost of the panel. A lot of conventional photovoltaic panels have effectiveness from 14% to 20%.
