Measuring Open Circuit Voltage with a Photovoltaic Multimeter
To quickly test your solar panel, first, check the panel's Voc (open-circuit voltage) and Isc (short-circuit current) from the label. Measuring the Voc is a straightforward process: (See Also: How to Test Computer Power Supply with Multimeter? Simple DIY Guide) Prepare the multimeter: Set your multimeter to the DC voltage (VDC) setting. Based on real PV installation scenarios, the following five multimeter measurement techniques cover nearly all high-frequency operations at solar project sites and can significantly improve safety and diagnostic accuracy.
