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


according to daily problems, e.g (Jackery Solar Kits). a 250 watt STC component might create 195 watts in NOCT conditions. Nominal Watts are the AVERAGE continual DC power generated in day-to-day problems for sunlight and temperature level. NOCT irradiance at 800 W per square meter, ambient temperature at 68F (20C), solar battery temperature level at 113F (45C), wind rate 2 mph


A greater % is better, however be sure to stabilize that with the price of the panel. A lot of common solar panels have performance from 14% to 20%.
