Solar Panel STC vs NOCT Rating: What 400 W Really Means
Solar panel STC vs NOCT rating compares a laboratory nameplate measurement with a standardized operating-temperature estimate. STC uses 1,000 W/m² irradiance and a 25°C cell temperature, while NOCT uses approximately 800 W/m², 20°C ambient air, and natural heating. STC ranks modules; NOCT helps estimate field behavior.
