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 Optimal Watts are the REAL-WORLD rated MAXIMUM DC power produced under PVUSA Test Conditions for sunshine and temperature level.


according to everyday conditions, e.g (solar inverters). a 250 watt STC component may generate 195 watts in NOCT problems. Nominal Watts are the standard continuous DC power created in day-to-day problems 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 mph


A greater % is better, yet make certain to balance that with the price of the panel. Many standard solar panels have performance from 14% to 20%. Some higher effectiveness panels can be dual the price of typical performance panels.
