How this is modelled

Compounds this panel’s own published first-year (2%) and annual (0.25%/yr) degradation figures against its 400 W rated (STC) output, then derates for the ambient and irradiance selected. Output is scaled roughly linearly with irradiance (1000W/m² against the 1000 W/m² STC reference). This is the dominant real-world effect at low light, whether from cloud, shading or soiling. Output is then further derated for heat, from this panel’s own NOCT (44°C) and temperature coefficient (-0.34%/°C), giving an estimated cell temperature of 60°C at that ambient and irradiance. A datasheet-derived estimate, not a field measurement or a warranty guarantee: it does not account for this panel’s own low-light efficiency response (a separate, less-consistently-published spec), or for wind and system design. See NOCT and temperature coefficient in the glossary.
