STC irradiance at 1000 W per square meter, cell temperature at 77F (25C), air mass AM 1.5. according to PVUSA test conditions, e.g. a 250 watt STC module might produce optimal 225 watts in PTC real-world conditions. PTC Height Watts are the REAL-WORLD ranked MAXIMUM DC power produced under PVUSA Test Problems for sunshine and temperature level.


according to day-to-day problems, e.g (Zendure Solar Kits). a 250 watt STC module might produce 195 watts in NOCT problems. Nominal Watts are the AVERAGE continual DC power produced in day-to-day problems 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 rate 2 miles per hour


A greater % is much better, however make certain to balance that with the cost of the panel. Most standard photovoltaic panels have efficiency from 14% to 20%.
