Step 1: Measure Open Circuit VoltageStep 2: Measure Short Circuit CurrentStep 3: Measure Operating CurrentDifferent solar panels will have information on the sticker on the back showing how to test. (1) Using a voltage meter, locate the open-circuit voltage (Voc) on the specifications label on the back of your solar panel. Write it down for later use. To measure the voltage of a DC circuit, you should prepare your multimeter by plugging the black probe...See more on toolsweek UNI-T Meters
