Manufacturing of Solar Panels | Module Testing Process

Once the modules are manufactured, they will move on to the final 3 tests to ensure the quality of the finished product. Firstly an insulation resistance test will be carried out, DC current will pass through the component for one minute, if the panel can endure the current, it is passed else failed.
The second is the power test. The output current, voltage, power, etc. of the components will be tested and form label information, and the staff will stick them on the backboard for distinction.
Finally, the second EL test and visual Inspection are carried out to minimize the detection error.
