Short-circuit current

Current at zero voltage, standard conditions

Unit A

What it is

The current the module delivers into a short circuit at standard test conditions, in amperes. The circuit model is fitted through the short-circuit current and the open-circuit voltage at standard conditions and a third point set by the One-diode STC point step: the datasheet maximum-power point, or a maximum equal to the nameplate.

Typical values and how to get it

The module datasheet value. A PAN file carries it too. If not given: the module runs on the PVWatts DC model, which does not read it. The one-diode models need it: a request that names one of them without it is refused.
