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 may generate optimal 225 watts in PTC real-world problems. PTC Height Watts are the REAL-WORLD rated optimum DC power created under PVUSA Examination Problems for sunlight and temperature level.

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

A greater % is much better, however make sure to balance that with the expense of the panel. A lot of typical solar panels have efficiency from 14% to 20%.
