Roam Gear Black Solar Bracing Plates (4 Pieces)

Aluminium is the preferred choice for off grid travel because it naturally resists corrosion and rust, particularly in coastal environments. Steel brackets are often heavier and can begin to rust at the mounting points if the protective finish is scratched or chipped during installation.

Using aluminium keeps the total weight down on your roof racks while providing a solid fix that handles the constant vibrations of corrugated outback tracks. It is a long term choice that avoids the maintenance issues associated with steel in harsh Australian conditions.

These aluminium brackets are designed to be universal and work with almost any rigid solar panel featuring a standard aluminium frame. The pre drilled holes in the brackets usually align with the factory mounting holes on the panel frame, though you can easily drill new ones for a custom fit.

This versatility makes them a practical choice for securing your power source to a variety of surfaces. Using a universal bracket allows you to mix and match hardware without worrying about brand specific compatibility. It is a straightforward way to keep your setup flexible as your needs change.

A set of four brackets is usually sufficient to secure the corners for a standard solar panel under 100W. If you are mounting a larger unit, such as a 160W or 200W panel, adding two extra side brackets is a smart move to prevent the frame from flexing in high winds or during off road travel.

Extra support points help distribute the wind load and reduce the stress on individual fasteners. This is a practical way to maintain a secure setup on long outback hauls where constant vibration is a factor. Keeping the panel stable helps protect the glass and internal cells from damage over time.

Mounting to a 4WD roof rack involves bolting the brackets directly through the rack mesh or rails using stainless steel hardware. Most platform style racks have T slots or channels that allow for a clean installation without needing to drill into the rack itself.

This creates a mechanical connection that is highly resistant to shaking loose on corrugated roads. Always make sure there is an air gap beneath the panel to allow for cooling. Proper airflow beneath the cells helps maintain charging performance even during the peak of a hot Australian afternoon.
