OMCO Solar

OMCO Solar is a premier manufacturer of solar racking and tracker solutions for community, commercial & industrial, and utility scale projects. Their expertise in fixed tilt and single-axis tracker systems stems from decades of steel manufacturing, beginning in 1955 when OMCO Holdings was founded. OMCO developed the first American steel fabrication and assembly facility specific to the utility-scale solar market. As a major manufacturer, OMCO has been driving innovation for solar structures and construction for over 20 years.

Pierceton Plant-Origin and CHOICE

Posts per row: Dependent on soil conditions, type of posts and row length — average is 11 to 13 per row.
Row lengths: While 96 modules per row is most common, OMCO Solar can customize to accommodate up to 112. Unique bearing technology allows long straight rows — 4 strings when others can only mount 3 — fewer motors and controllers per MW.

Slope Tolerances: Up to 15% for a North-South Slope

Design:  OMCO Origin 2L (2-in-Landscape) Bifacial Trackers are primarily constructed of galvanized steel and cast aluminum.  Bearings include a wear surface composed of a unique long-life, low-friction, self-lubricating acetal blend. A balanced design allows for more accurate targeting and reduced energy consumption. Some subassemblies are factory preassembled and shipped as single units for labor, time and cost savings. The unique bearing adjusts to accommodate post misalignment. OMCO Origin 2L Bifacial Trackers are open on the back — no torque tube blocking the cells — for highest energy production. The height of the tracker is low — like 1-in-portrait trackers — to minimize installation labor. Foundation options include OMCO-produced driven C posts (preferred) and driven I or W posts, and ground screw foundations.

Factory Preassembled: Some subassemblies are supplied as single, preassembled units for installation labor savings.
Balanced Design: Axis of rotation at the center of mass of the table — improves targeting accuracy, increases energy production and minimizes energy consumption.
Long Wear Life: Bearings tested to more than 40 years equivalent life.
7 Dimensions of Adjustment: Bearings adjust to accommodate post misalignment, avoiding project delays.
Over 20% Higher Back Side Production: The open back allows uniform backside irradiance, which is critical for long cell and module life.
Shortest Lead Times: Partners benefit from expedited delivery due to OMCO Solar’s four strategically located U.S. manufacturing plants. Lead times are typically 8 to 12 weeks.

Domestic Content: OMCO makes all structural components with domestic steel and is well positioned for IRA ITC benefits.

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.

Vanguard 2P is a two in portrait independent single axis tracker. The newly designed tracker features an innovative multidrive system comprising of three linear actuators connected by cardan transmission bar. Vanguard 2P utilizes W pile as its foundation along with patented spherical bearings and highly reliable square torque tube. Additionally, Vanguard 2P uses reinforced purlins to optimize layouts with the new Trina Solar 600W+ large format modules.

The construction starts with driving the piles, installing the bearing supports, linear actuator supports, bearing housing/ lever /torque tube pre-assembly. Pre-assembly is an assembly of several components pre-assembled on the ground and installed on the structure for a more efficient installation process. Each project site will have different pre-assemblies for different sections of the tracker. The install manual and construction sequence documents will be project specific and optimized for an easier installation process. Adjustments can be made prior to applying the torque and if re-adjustment is needed, it can be done.

The next step is installing the linear actuator in the specified positions, and then the joining clamps to connect the torque tubes. After that, the transmission system supports are installed on the torque tubes. Following that, the transmission bar and cardon are installed. After that the purlins pre-assembly is prepared and installed before installing the modules. Then the TCU, self-powered panel and grounding strap.
