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 Top Watts are the REAL-WORLD rated optimum DC power generated under PVUSA Test Problems for sunlight and temperature level.

 

 

 

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


A greater % is much better, but be sure to balance that with the cost of the panel. Many standard solar panels have effectiveness from 14% to 20%.
