This is because short-circuit current is a parameter used to measure the quality of solar panels, which can only be detected by a module tester. Multimeters themselves are loads, so the parameter to be checked is the working current data. In addition, the testing conditions for solar panels are 1000 watts/square meter and 25 degrees Celsius, and the testing should be carried out under standard light intensity. Solar panels will encourage users to equip themselves with solar panels that meet local requirements based on different purchasing areas and climate conditions.
