It has the lowest part count per MW and integrated wire management. The patented Gravity Clip reduces module install time by 35 percent. The 3-rail design is an excellent solution for bifacial modules, providing low backside shading. The TITAN has the industry’s strongest C-pile with opportunities for adjustment. The screws are telescoping providing 18” of adjustability for topography.

RR PRe Engineered Kit

Number of pieces: varies for each project – avg. 548 pieces for a 12KW project

Installation: The Ready Rack Pre-Engineered Kit is great for smaller projects and comes in two module increments. The kit has multiple foundation types and provides a solution for all subsurface conditions. It comes with everything needed to install the racking and is delivered on a 4’x12’ pallet. Additionally, there is no need to source any pipes or concrete with this product. The layout and dimensions are site specific and can be easily referenced in the provided plans. The helical and ground screw foundations are simply installed by using a skid steer and auger attachment.

Advantages: Designed specifically for smaller residential and commercial solar installations, it comes with all required components and has approved engineering documentation already completed and included; just pick your parameters and go. The design is a simple configuration that allows contractors to install the system fast. A 10 kW system, for example, can be installed in one day. Integrated features allow for onsite adjustment and anchors paired with quick-install bracing make this simple system extremely robust.

APA Racking A Frame
Three pieces: Ground screw or helical, leveling flange, A-Frame.

Design: The helical piles or ground screws are driven with a rotary head. Then the A-Frame is attached to the piles with four bolts. The A-Frame uses a standard I-beam section to the solar tracker system. This allows seamless transition from driven I-beams to the A-Frames, leaving connection hardware the same. The leveling flanges allow for up to 20 in. of height adjustment to keep the A-Frame plum and level. The dual post design allows for ground screws or micro helicals for the foundation and are driven using a rock drill.

Advantages: The A-Frame advantage is its dual post design, allowing developers to substitute the traditional pile-driven foundation for a dual ground screw or dual helical foundation to accommodate rocky or softer subsurface conditions. The adjustability in the A-Frame also aids in dealing with topography and managing in-field adjustments to maintain the design of the array. Helicals are designed for softer soils, while ground screws are best suited for rocky or harder subsurfaces that have cobbles or other obstructions.

Turnkey specialties:

  • APA provides a full turnkey service from installing the foundation to the module installation. Anchor testing is also provided.
  • Hardware-only orders, giving customers the exact amount of hardware and foundation pieces they need to complete a project at a competitive price.
