Magnetic Solar Panel Car Holder

An angled, magnetic mounting system designed specifically for small solar panels (approximately 27x17.5cm 10.6x6.8 inches). This dual-bracket system lets you easily attach your solar panel to the roof or hood of any stationary vehicle to keep your power stations or auxiliary batteries charged while camping.

The design utilizes strong magnets embedded in the bottom of each bracket for a firm hold on metal surfaces, tilting the panel at an optimal angle to maximize solar efficiency.

🛠 Required Hardware

To assemble the stand as shown in the project photos, you will need:

• Magnets: 2x Heavy-duty rectangular block magnets screwed into the bottom channels.

• Magnet Screws: 4x Small countersunk screws to secure the magnets to the printed base

• Panel Hardware: 4x Bolts, washers, and wing nuts for quick, tool-free panel removal

🖨 Print Settings & Material Advice

⚠ IMPORTANT: Do NOT use PLA for this print. Because this holder sits in direct, intense sunlight on top of a hot car roof, PLA will soften, warp, and deform very quickly.

• Recommended Filament: PETG, ASA, or ABS for proper UV resistance and high thermal stability.

• Print Orientation: Print the brackets flat on their sides. This eliminates the need for messy supports and ensures maximum layer-line strength under mechanical stress.

• Infill & Walls: 20-30% infill with at least 3-4 perimeters to guarantee durability when tightening the wing nuts.

🛑 Important Usage Notes

• Stationary Car Only: This mount is designed strictly for a parked/stationary vehicle. Do not drive with the solar panel attached to the roof!

• Paint Protection: To prevent the hard magnets from scratching your car's clear coat, consider adding a thin layer of electrical tape, thin rubber sheet, or felt to the bottom face of the magnets.
