Disclosed is a method for attaching an interconnector of a solar cell panel. The method includes forming a first interconnector-jig coupling by fixing a plurality of first interconnectors to a jig, locating the first interconnector-jig coupling over a working table, fixing the first interconnectors and a first solar cell to each other, separating the jig from the first interconnectors, and attaching the first interconnectors to the first solar cell by applying heat to the first interconnectors and the first solar cell, which are thereby fixed to each other.
