solar panel mounting 3d model

Create a highly detailed yet 3D-print optimized model of a solar panel mounting system based on a real-world rooftop installation structure. The model must include a single rectangular photovoltaic solar panel mounted on a tilted support frame system. The entire structure should be designed as a unified but separable assembly suitable for multi-color 3D printing using PLA filament. The solar panel should have a flat rectangular shape with a clearly defined grid pattern on the top surface, representing photovoltaic cells. The grid should be evenly spaced and slightly engraved or embossed to ensure visibility after printing. The panel surface must be colored in matte black PLA, with subtle texture differences to distinguish the grid lines from the base panel. The panel frame should be thin but structurally defined, with clean edges, and integrated mounting brackets that connect to the support rails. Avoid overly thin geometry that may fail during printing. The support structure must c
