Sinclair Sky Rack 2.0 – 12 Panel Commercial Ground Mount Solar Racking Kit (Seasonal Adjustable)
The Sinclair Sky Rack 2.0 12-Panel Commercial Ground Mount Solar Racking Kit is a durable, ground-mounted solar panel support system designed for commercial photovoltaic installations using large-format solar modules.
Manufactured in the USA by Sinclair Designs & Engineering, the Sky Rack 2.0 provides a flexible mounting solution for solar projects where ground installation is preferred for optimal solar exposure and array positioning.
This 12-panel commercial configuration is designed for large-format solar modules measuring approximately 89.6" x 44.6". Its seasonal adjustment system allows the solar array's tilt angle to be modified throughout the year, helping accommodate changing sun positions and seasonal sunlight conditions.
The Sky Rack 2.0 features a streamlined structural design built around four primary components: C-channel posts, trusses, support struts, and Z-purlins. This simplified configuration is engineered to support efficient installation while providing a durable foundation for commercial solar arrays.
With seasonal tilt adjustment capabilities ranging from 15° to 60°, UL 2703 certification, and a 25-year manufacturer warranty, the Sinclair Sky Rack 2.0 offers a versatile mounting solution for commercial ground-mount solar installations.

Seasonal Tilt Adjustment System
The Sky Rack 2.0 features a seasonal adjustment mechanism that allows installers to modify the solar array's tilt angle according to the changing position of the sun.
The seasonal adjustment configuration provides an adjustable tilt range of 15° to 60°, offering flexibility to optimize panel positioning for different times of the year.
-
Winter Position: Steeper panel angles help capture lower-angle sunlight and can assist with snow shedding.
-
Summer Position: Lower panel angles accommodate the higher position of the sun.
-
Seasonal Flexibility: Allows the array to be repositioned as sunlight conditions change throughout the year.
The adjustment mechanism uses a dedicated seasonal adjustable jack connecting the truss and C-channel post. Sinclair's installation manual specifies making adjustments in 5-degree increments at each post to help prevent damage to the solar array.
For installations requiring a fixed mounting configuration, the Sky Rack 2.0 also supports fixed tilt angles between 5° and 35°.
Structural Design and Construction
The Sinclair Sky Rack 2.0 uses four primary structural components to create a reliable and efficient ground-mounted solar support system.
-
C-Channel Posts: Provide the primary vertical structural support for the solar mounting assembly. The manufacturer specifies structural steel posts with a G235 coating and Chem-Guard protection.
-
Trusses: Form the main structural framework supporting the solar modules.
-
Support Struts: Provide additional reinforcement and structural stability to the mounting assembly.
-
Z-Purlins: Serve as the mounting interface for attaching solar modules to the structure.
The system also accommodates optional Strongback reinforcement where required by project-specific structural conditions, including certain high-wind and high-snow-load environments.
Commercial Solar Panel Compatibility
This specific configuration is designed for large-format commercial photovoltaic modules with the following nominal dimensions:
Solar module dimensions, frame specifications, mounting holes, and clamp compatibility should be verified before ordering.
The Sky Rack 2.0 supports module attachment using either compatible mounting hardware or approved end-clamp and mid-clamp assemblies, depending on the module and installation configuration.
Structural and Electrical Certifications
The Sinclair Sky Rack 2.0 is tested and recognized to UL 2703 standards for solar mounting system safety, electrical bonding, and grounding.
The manufacturer also identifies compliance with UL 1703 fire standards.
According to the installation manual, the system is designed for photovoltaic modules with a maximum series fuse rating of 20A.
For clamp-based installations, module compatibility must be checked against Sinclair's UL 2703 Qualified Modules list.

Site Planning and Installation
The Sinclair Sky Rack 2.0 is designed for ground-mounted solar installations and can be installed on suitable low-sloped terrain.
The manufacturer recommends selecting a site that is as level as possible, ideally with an East-West slope of approximately ±5 degrees.
Foundation and post installation requirements depend on site-specific conditions. The manufacturer's installation manual describes several foundation approaches, including:
-
Driven C-channel posts.
-
Concrete footings.
-
Concrete ballast blocks.
Post embedment depth and foundation dimensions must be determined according to regional conditions, applicable building codes, and engineering requirements.
Additional installation considerations include:
-
Soil characteristics and foundation requirements.
-
Structural post spacing and array configuration.
-
Local wind and snow loading conditions.
-
Solar module compatibility and mounting requirements.
-
Electrical bonding and grounding.
-
Applicable building codes and permitting requirements.
Sinclair recommends consulting a licensed professional engineer to determine appropriate structural requirements and foundation design.
Installation should follow the manufacturer's instructions and applicable electrical and building codes. The manufacturer also recommends that installation and subsequent modifications be performed by a factory-authorized representative.
