The Fast Rack GMX Ground Mount for 24 x LONGi 505W Bifacial Solar Panels is a heavy duty ground mounting solution designed for Canadian residential, commercial and off grid projects. Built around Fast Rack’s GMX rail system, this package is sized to support twenty four LONGi 505W bifacial modules, giving you up to 12,120 W of DC capacity when fully populated.

The GMX structure is engineered for Canadian snow and wind loads and uses a galvanized steel and aluminum design for long term corrosion resistance. Adjustable tilt options allow you to optimize array angle for your latitude or site specific energy goals, while the ground mount format keeps panels accessible for cleaning and maintenance without roof work.

This configuration is ideal for larger off grid systems, homesteads, farms and small commercial installations that want a dedicated solar field paired with battery storage and inverter systems such as EG4. With a clean layout, proven hardware and clear installation guidelines, the Fast Rack GMX Ground Mount provides a stable foundation for high output LONGi bifacial arrays.
