Solar Stack eliminates the need for rails and racks. Instead, your additional mounting hardware can be installed directly to Solar Stack. This allows you to install solar panels directly to our pedestal.

Contractors can either run their wire management from pedestal to pedestal with cable ties or they can use solar panel clips.
