Standard Package

Includes world-class engineering, stamped structural packages, and project management support to ensure success on every size project

Speed Package

Bolsters the standard package with the inclusion of components specially designed for maximum adjustability, and delivery of ready-to-install, pre-assembled parts. Perfect for projects where installation efficiency is the top priority.


Tell Me About Pricing and Lead Times

Through universal parts and a module-independent design, GeoPro can be offered at the industry’s lowest price point and with the shortest lead times.

GeoPro is Ideal for Projects of What Size?

GeoPro is an ideal solution for utility-scale and commercial solar projects of 100 kW and larger.

What Tilt Angles are Possible?

GeoPro’s tilt can range from 10° to 30°.

What Foundation Options Exist? Do you Have a Ballasted Ground Mount Option?

The system offers maximum foundation flexibility for soils of all types, including i-beam, round post, screw pile, helical pile, ballast or a hybrid of more than one.

Can GeoPro be Installed in Harsh Environments?

GeoPro can be adapted to any commercial or utility-scale PV project site and optimized for a project’s unique wind, snow and geotech conditions in even the world’s harshest environments.  The system is able to accommodate snow loads of up to 70 psf and wind loads of up to 160 mph.

ROLLING TERRAINCan the System Be Installed on Difficult Terrain?

The ground mount solar system boasts an industry-leading 20 percent east-west terrain following capability on both constant slope or rolling terrain, while allowing piles to be installed plumb.

What Modules Can Be Installed on the GeoPro System?

GeoPro can accommodate all major framed and frameless PV modules. In addition, the system is module independent – able to accommodate last minute module choice changes without requiring any changes to project design. Customers can choose landscape or portrait module orientation depending on their commercial or utility-scale solar project priorities.

Can I use First Solar modules with GeoPro?

Yes. SunLink is a First Solar Optimized Vendor Partner, and our mounting systems work seamlessly with First Solar modules.

What Sort of Project Density Is Possible with GeoPro?

Small table sizes arrays can be sized incrementally to maximize a site’s installed solar.

How Can GeoPro Mitigate Pile Driving Refusals?

It is possible to swap in a ballasted foundation without changing the system configuration.

What Wiring Advantages does GeoPro Offer?

Both wire management and grounding are integrated into the racking, simplifying total balance of system complexity and significantly lowering both labor and material costs.
