How To Test Voltage On A Solar Panel With Multimeter

Make sure that you are measuring at the suitable voltage level for a solar panel.

How to test voltage on a solar panel with multimeter.

For example if your panel has approval for 30 volts set the multimeter to have a higher reading. Some exceptions may apply based on panel type. You want to choose a voltage range capable of displaying the maximum possible voltage of the panel in open circuit this means that if you have a panel rated for 20 volts you should set the multi meter to read up to 200 volts to ensure that you receive an accurate reading. To test a 18v solar panel voltage output directly put your solar panel in direct sunlight set your multi meter to the dc volts setting.

Measure at higher volts than what your panel is approved for. Next you need to set your digital multimeter to volt settings dc. You will want to ensure that you place the positive to positive and negative to negative when attaching your multimeter to the connection on the back of your solar panel. Simply touch the solar panel leads with the multi meter probes matching their corresponding polarity red to red black to black.

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. As most solar panels are 12 volts the solar panel test methods are basically the same. How to test solar panels for volts using a digital multimeter the first thing to do is place your solar panel outside in direct sunlight. Testing your solar panel is easy.
