How To Test A Portable Solar Panel

To check the solar battery charger system s production you just need to press the amp volt button to toggle between three screens of information you can see this in our video.

How to test a portable solar panel.

The renogy solar system charge controller makes monitoring these portable solar panels easy. Step 3 measure current. 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.

Disconnect the solar panel completely from the battery and regulator angle the solar panel towards the sun ensure that the multimeter is set to measure volts measure the voltage between the ve and ve terminals by connecting the negative contact from. As long as the amp meter is rated higher than the solar panel you will be able to measure the output effectively. Attach the meter to the positive and negative terminals on the solar panel and make sure the panel is properly exposed to sunlight. 3 screens show you.

To measure open circuit voltage volts v oc. 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. Set the meter to above 200 vcd to ensure you get the most accurate reading possible. As most solar panels are 12 volts the solar panel test methods are basically the same.

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.
