NOVELTY - A bracket system for use with a photovoltaic (PV) panel frame system, comprises a fastener adapted to extend through the elongated slot and the hole to secure the first and second members fixedly to a frame system component, and further such that the first member can be secured at a desired inclination relative to the frame system component.    USE - The bracket system is used with a PV panel frame system (claimed).    ADVANTAGE - Adjustable mounting bracket for a PV panel frame system is provided. The bracket assemblies can thus be quickly and easily configured to the desired inclination. Because of the significant degree of inclination adjustability that the bracket assemblies provide, the bracket assemblies can be used in a wide variety of applications where different degrees of inclination are needed. For a manufacturer, this significantly simplifies the manufacture of a PV frame system, as well as reducing the inventory of individual component parts that need to be kept on hand to meet the needs of different installations. Also, if the installer begins an installation and realizes that the needed degree of inclination for a PV panel system is slightly greater or lesser than originally planned for, this is no problem with the bracket assemblies. Minor variations in the needed degree of inclination can easily be accommodated.    DETAILED DESCRIPTION - A bracket system for use with a PV panel frame system, comprises a bracket assembly including: a first member having a neck portion and a foot portion extending non-parallel to the neck portion, the foot portion having a radius of curvature; a second member having a first surface having a radius of curvature that generally matches the radius of curvature of the foot portion; and one of the first member and the second member having an elongated slot formed in it and the other one of the first member and the second member having a hole; and a fastener adapted to extend through the elongated slot and the hole to secure the first and second members fixedly to a frame system component, and further such that the first member can be secured at a desired inclination relative to the frame system component.
