How to test solar panel amps using a multimeter the first thing to do is place your solar panel outside in direct sunlight.
How to test a solar panel with a multimeter.
Measure at higher volts than what your panel is approved for.
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.
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.
Set multimeter to 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.
Make sure that you are measuring at the suitable voltage level for a solar panel.
Tilt the solar panel in order for your solar panel to have full sunlight exposure.
