Equivalent PR: every dual-string MPPT string brought up to the single-string reference, then capped at each inverter's ceiling (185 kW × its own setpoint) and at the site export limit. Same contract intervals and E_ideal as the real PR.

One pair of points per day (axis zoomed to the data, not from zero). The gap between them is the energy the dual-string MPPTs could have added after every ceiling is applied.

Dual ÷ single: median ratio of dual-string to single-string string power (bins above 200 W/m²), split by whether the inverter/site was at a ceiling. Allocation = strings match when unconstrained and only fall behind while limited (nothing to recover). Real loss = they fall behind even when nothing is limiting. Click a row for detail.

Each dot is one 15-min bin: x = single-string reference power, y = dual ÷ single. If the gap is power-limit allocation, the dots stay near 1.0 until a ceiling is hit and drop only in the limited classes; a real loss drops in the unconstrained class too.

Inverter AC power: actual, equivalent, and the ceiling it was held to.
