Short-circuit current test of photovoltaic panels
To measure the short circuit current (Isc) of a solar panel, you connect a multimeter set to DC amps directly across the panel's positive and negative terminals while the panel is in full sunlight. This gives you the maximum current the panel can produce, since there's no load slowing the flow of. One key aspect of solar panel performance is the short circuit current (Isc), a critical parameter that indicates how much current a solar panel can produce under ideal conditions.
