How to test a solar panel with a multimeter.

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. 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. 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.

Make sure that you are measuring at the suitable voltage level for a solar panel. Next you need to set your digital multimeter to amps settings dc after that you will need to set your multimeter to the highest amperage sensitivity to avoid blowing the digital multimeter s fuse. Measure at higher volts than what your panel is approved for.
