1. A method comprising:
- activating a bypass link between an input of an electronic module and an output of the electronic module;
performing a flash test on a photovoltaic panel while the bypass link is activated, wherein the photovoltaic panel is connected to the input of the electronic module; and
deactivating the bypass link between the input of the electronic module and the output of the electronic module responsive to a determination that the flash test is complete.

Abstract
A method for testing a photovoltaic panel connected to an electronic module. The electronic module includes an input attached to the photovoltaic panel and a power output. The method activates a bypass to the electronic module. The bypass provides a low impedance path between the input and the output of the electronic module. A current is injected into the electronic module thereby compensating for the presence of the electronic module during the testing. The current may be previously determined by measuring a circuit parameter of the electronic module. The circuit parameter may be impedance, inductance, resistance or capacitance.
