Solar module washer clip
A washer clip device includes a first clip arm, a second clip arm, at least one grounding element at the first clip arm and/or the second clip arm, and a fastening aperture extending through the first clip arm. The first and second clip arms are joined together at a first end of the washer clip device to define a first internal clip area adjacent the first end, and the first and second clip arms are spaced apart from one another at a second end of the washer clip device to define a receiving gap between the first and second clip arms and adjacent to the second end. This washer clip device is movable between a coupling configuration and a receiving configuration, with the receiving gap being larger when in the receiving configuration than when in the coupling configuration.
