How are the strings connected?

Panels in a string are connected in series. The calculation distributes identical strings across the station’s modeled inputs; extra strings on one input are parallel. This is not a wiring diagram.

Only identical panels and equal string lengths are modeled. Fuses, cable gauge, grounding and local installation rules need a separate check.

Sources first

No regionally documented model for this edition yet.

None of the shared product records is tied to a source that documents this model for this edition's market. Without that evidence we show no shortlist, no "best match" and no buying link. The calculation above keeps working on your own input.

A model only appears here when its own cited source documents this market's execution.
