PTC Optimal Watts are the REAL-WORLD rated MAXIMUM DC power created under PVUSA Examination Conditions for sunshine and temperature.
according to everyday problems, e.g (Zendure Solar Kits). a 250 watt STC module may produce 195 watts in NOCT problems. Small Watts are the AVERAGE constant DC power generated in daily problems for sunlight 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, but be sure to balance that with the price of the panel. A lot of common solar panels have efficiency from 14% to 20%. Some greater efficiency panels can be double the cost of average performance panels. You may save a great deal of money merely by including one extra panel with typical performance to accomplish the same result.
