How to test a solar panel using a micrometer.

Testing the 12 volt solar panel. To test a 12v panel meters should always be set to the dc voltage area which usually identified by the symbol below. In this section we outline how to do this using a multimeter to measure current amps and voltage. 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.

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. Results will vary depending on sun strength time of day angle of light and temperatu. Sometimes you will want to check that your solar system is performing properly or you may simply want to know what output your panel is giving. Testing solar panels for volts to test solar panel voltage output put your solar panel in direct sunlight set your multi meter to the volts setting and.

Test your solar panel regulator. You want to choose a voltage range capable of displaying the maximum possible voltage of the panel in open circuit that is when not connected to the battery or charge controller. You can test your completed 63 watt solar panel by using your multi meter like you did before with your solar cells and your stringers.
