How to test a bare solar panel with a multimeter.

If you need a multimeter you can get the innova 3320 auto ranging digital multimeter here htt. Switched multimeter this type of multimeter manually switches between the ranges to get the most accurate reading. Some exceptions may apply based on panel type. Including the solar panels.

Touch the multi meter s red positive lead to your solar panel s positive wire. Using a multimeter to test a solar panel. Testing the 12 volt solar panel. 3 amps is about normal since your panel may not be currently getting maximum sunlight.

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. 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. All you need is a multimeter.

The amp reading on your multi meter should be close to or just under 3 5 amps. When you buy solar panels you need to check quite a few things to make sure you are getting the right kind including checking the solar panel output buying and installing solar panels requires some research to determine how many you need to get enough output to satisfy your electric needs. Simply touch the solar panel leads with the multi meter probes matching their corresponding polarity red to red black to black. 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.

A multimeter is a device that you can use to test the voltage and current of any device. For example if your solar panel is 20 volts rated your digital multimeter should be set to a reading of 200 volts for an accurate reading. I think i stuffed up explaining the amps setting on this one as some of the megas ma. 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.

The next step is to connect the black probe to the com labelled port and the red probe to the v ma labelled port. See how to test your solar panel for open voltage and current reading. While using this multimeter select. Testing your solar panel is easy.

You then need to touch your solar panel to the multimeter probe. Then touch the multi meter s black negative lead to your solar panel s negative wire.
