How To Test A 12v Solar Panel

This is the most common volts rated for solar panels therefore the testing methods will be typically similar.

How to test a 12v solar panel.

If the solar panel is used the reading might be lower. The system i tested includes two 120 w solar panels in parallel a pulse width modulation pwm charge controller and 225 ah wet deep cycle battery. As most solar panels are 12 volts the solar panel test methods are basically the same. This is quite usual.

Set the meter to above 200 vcd to ensure you get the most accurate reading possible. Testing solar panels for amps to test solar panel amperage output put your solar panel in direct sunlight set your multi meter to the dc amps setting. Connect the positive lead of the multimeter to the positive wire or terminal of the solar panel and the negative lead of the multimeter to the negative wire or terminal of the solar panel. This article describes how to test a small 12 v solar power system.

To ensure that you don t blow your device s fuse set the maximum amperage sensitivity to well above your expected reading. You can always check if your solar panels are healthy as well as getting more detailed information about the status of your battery. Results typical 12v nominal panel. The multimeter will now show the open circuit voltage of the solar panel.

Ensure that the multimeter is set at 10a at least to start with. To test a 12v panel meters should always be set to the dc voltage area which usually identified by the symbol below. Measure the current by connecting the ve lead on the voltmeter to the ve on the panel and the ve from the voltmeter to the ve on the panel. Disconnect the alligator clips only after you have switched off the multimeter.

Angle the solar panel towards the sun. 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. Then touch the multi meter s black negative lead to your solar panel s negative wire.
