NOVELTY - The device (15) has an angle bracket (29) provided with first and second bracket portions (43, 45) extending at an angle from opposing sides of a vertex edge, where the first bracket portion includes toothed outer surfaces (47) configured to engage opposing horizontally toothed inner surfaces. A nut (55) and a non-countersunk bolt (62) engage and secure first and second slots (49) and a third slot (51) for constraining the angle bracket to be adjusted horizontally along the horizontally toothed inner surfaces and vertically in discrete steps along height of a base portion channel (37).    USE - Adjustable solar panel tile roof mounting device for mounting equipment such as solar panel e.g. solar photovoltaic (PV) panel and solar thermal panel, to a roof with roofing tiles such as flat roof tiles and curved barrel tiles.    ADVANTAGE - The device is constrained to adjust in discreet steps in two directions and continuously in third direction after the mounting device is mounted to the tile roof, thus allowing an equipment-mounting portion of the mounting device to be adjusted in three directions relative to a position of the device attached to the tile roof, and hence simplifying installation as the mounting device allows flexibility in placement of the equipment racking system relative to the mounting device. The device can be placed to engage the rafters, and ensures two discrete step adjustments along direction of maximum stress as compared with continuous step adjustment, thus assuring minimum slippage in directions of stress while allowing for flexible adjustment along a line of less stress.    DETAILED DESCRIPTION - The first and second slots are longitudinal slots. The third slot is a transverse slot. The angled bracket is formed as a right angle L-bracket.
