This panel can also collect light from the back. To avoid an optimistic result, our calculation only counts its rated 220W front side.

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.

Regional evidence

Recommendations are not activated yet.

Two regional manufacturer specification profiles are documented in Products. Recommendation cards remain closed pending exact socket, package, image-rights and local purchase evidence. The calculator still works with your own values.

A documented specification profile alone does not establish a purchase recommendation.
