Definition and decision context

Definition

NREL reports low-irradiance losses of photovoltaic modules as a module-efficiency behavior considered in PV energy-performance analysis.

Verified August 28, 2026

Why it matters

NREL’s low-irradiance analysis treats the loss as module-dependent, not as proof of a particular system’s production advantage.
