Abstract: Wall panel systems are provided. The systems use interlocking brackets to attach photovoltaic (PV), ceramic, or other rigid wall panels to an exterior wall of a building. The interlocking components include a plurality of wall mounting brackets configured to carry the dead loads of the respective wall panels, and a plurality of panel brackets that may be quickly hung from the wall mounting brackets. The wall mounting brackets are configured to be operatively fastened to an exterior wall surface, while each of the panel brackets is adhesively attached to the rear surface of a respective panel. Each of the wall mounting brackets and the nested panel brackets is substantially similar in dimension and configuration. Further, the system is configured to allow wall panels to be attached to the bracket assemblies in any sequence. A method for attaching architectural wall panels is also provided herein.
