PERTURB & STABILIZE

Device-aware photovoltaic operation.

Conventional MPPT primarily determines the operating point that maximizes instantaneous power. Perturb & Stabilize considers the relationship between operating conditions, device degradation, and long-term harvested energy.

01Problem

Instantaneous maximum power does not necessarily describe long-term device behavior.
