Why This Kit Works

7.2kW DC System Size
Built with sixteen 450W modules for strong production in a compact footprint.

Ground Mount = Better Production
Install at the ideal angle and orientation for your site—no roof limitations.

Seasonal Adjustable Tilt
Maximize output year-round with adjustable angles from winter to summer.

Simplified Structural Design
The Sky-Rack system uses a streamlined component approach for efficient installs.

Seasonal Tilt Adjustment 

The Sinclair Sky-Rack 2.0 gives you the flexibility to dial in production across the seasons:

• Fixed Tilt Option: 5° to 35° for standard installs
• Seasonal Adjust Range: 15° to 60° for optimized year-round output

Real Benefit:

• Steeper tilt in winter (up to 60°) improves low-angle sun capture and helps shed snow
• Lower tilt in summer increases total daily production
• Adjustments can be made incrementally to maintain system performance

This flexibility translates directly into higher annual energy yield compared to fixed systems.

Sky-Rack 2.0 Ground Mount System

The Sky-Rack 2.0 is engineered for performance and install efficiency:

• Composed of four main structural components: C-channel posts, trusses, support struts, and Z-purlins
• Designed for fast installation and reduced complexity
• UL 2703 certified for bonding, grounding, and safety
• Built with galvanized steel components for durability
• Backed by a 25-year warranty
