How to know solar panel voltage.

Using a multimeter for solar panel tests step 1. Step 2 measure amperage. What you ll see over to the right is an example of a voltmeter measuring voc with a junction box. Voltages can be read on a pv module with the use of a voltmeter or multimeter.

Locate the converter box. The power rating tells you how much power a solar panel was designed to produce. This would be the view from the back of the pv module. It measures the wattage of a panel when it is operating at standard test conditions.

Open circuit voltage can vary depending on your solar panel but the readings we are usually looking for are in the range of 15 to 23v. Some exceptions may apply based on panel type. Wattage power voltage x current. So you need to measure both the voltage and the amperage of the solar panel to determine the power production that you will get from the system and whether or not it will be sufficient for you.

Measuring voltage and solar panel testing. Simply touch the solar panel leads with the multi meter probes matching their corresponding polarity red to red black to black.
