PTC Height Watts are the REAL-WORLD ranked optimum DC power produced under PVUSA Test Conditions for sunshine and temperature level.
according to everyday conditions, e.g (Bluetti Solar Kits). a 250 watt STC component may generate 195 watts in NOCT conditions. Small Watts are the standard continuous DC power generated 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 speed 2 mph
