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


according to day-to-day conditions, e.g (Jackery Solar Kits). a 250 watt STC module may produce 195 watts in NOCT conditions. Small Watts are the AVERAGE continual DC power produced in EVERYDAY conditions for sunshine and temperature. NOCT irradiance at 800 W per square meter, ambient temperature level at 68F (20C), solar cell temperature level at 113F (45C), wind speed 2 miles per hour


A higher % is better, yet make certain to stabilize that with the cost of the panel. The majority of common photovoltaic panels have effectiveness from 14% to 20%. Some greater performance panels can be double the cost of ordinary efficiency panels.
