How to Test Solar Panels with a Multimeter (3-Step Guide)

Step 2: Measure Short Circuit Current (Isc) The short circuit current (Isc) on a circuit panel is located on the specifications label on the back of the panel. Record this number for later use. To prepare your multimeter to measure amps, move the red probe to the amperage terminal and set your multimeter to the amp setting (A).
