The disclosure describes various stackable corner protector configurations. The corner protectors can have curved lateral surfaces that allow the corner protectors to be decoupled from a photovoltaic module to which they are coupled to by rotating one end of the corner protectors away from the object. This removal process works even more efficiently with multiple stacked corner protectors as the stacked corner protectors can be concurrently removed from the object by rotating the stacked corner protectors away from the object together. The corner protector can also include one or more attachment features for securing the corner protector to the object. For example, when the corner protector is installed on a photovoltaic module, the attachment feature can engage a lip defined by a recess or channel of the photovoltaic module.
