Product Testing

After receiving the product, you can use the following methods to
test the productʼs performance.
Required tools: multi meter;
1. Connect a crocodile clip cable to the solar panelʼs output cable and
adjust the multimeterʼs setting to 200V. Connect the red probe to the
red crocodile clip and the black probe to the black crocodile clip.
Check the value that is displayed on the multimeter. The value should
fall between 20±2V (this may vary according to weather conditions).
2. Connect a cable with a crocodile clip to the solar panelʼs output line
and set the multimeter to electrical current testing mode. Collect the
red probe to the red crocodile clip and the black probe to the black
crocodile clip. Check the value that is displayed on the multimeter
and compare it with the short-circuit current value printed on the
label attached to the rear of the solar panel. Under good lighting and
temperature conditions, these two values should be close.
