1. A method, comprising:
- measuring a parameter of an electronic module, the electronic module comprising an input attached to an output of a photovoltaic panel, and a power output;
creating a low impedance path between the input of the electronic module and the power output of the electronic module by activating a bypass link between the input of the electronic module and the power output of the electronic module; and
injecting a current into the electronic module, wherein the current is determined based on the measured parameter.

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.
