Before testing photovoltaic solar panels, you need to understand the test conditions: test principles, test tools, test standards (environment), and test parameters. The following is a detailed description for everyone.

Test principle

The working principle of the test system is: when the flash shines on the battery under test, the electronic load is used to control the current change in the solar cell, and the voltage and current on the battery’s volt-ampere characteristic curve, temperature, light intensity, and test data It is sent to a microcomputer for processing, display and printing.
