Our EarthBallast mounting option is ideal for most terrain types, particularly when excess soil or crushed rock is available on-site. The geotextile fabric creates a trampoline effect when it's pulled tight and has a minimum 2" air gap above the ground before the soil or rock is placed on the geotextile fabric. This is what creates the down force for holding the frames down in high wind situations.

 A skid-steer loader or tractor can be used to evenly distribute earth fill over the included geotextile material that is stretched across and epoxied to the top of each solar rack frame prior to the solar panels being installed, creating a strong heavy ballast with a clean and natural look when completed. The EarthBallast system can also be used with sand bags for ballast.

PRO TIP: Ballast with light sand or crushed light colored rock for increased bifacial gain

*1" Conduit Pipe / EMT (NOT included) is required to link the frames together and can be sourced at any local hardware or electrical supply store in 10' lengths, which is enough to cover two panels.

*We recommend using this system with two 3/4" round concrete forming steel stakes for each frame to provide added strength and easy leveling of the system.
