Tracker Height: Project specific Tracker Length: 304' (90 module
row)
Pile Count: 7 modules per pile
Modules per Row: Up to 90 modules
Module Mount: Self-aligning, auto spacing direct bolt
Slope Tolerance: Up to 10° n/s Tracking Range: Up to 110° (+/- 55°)
Standard Configuration: 1 in Portrait, 2 in Landscape (crystalline); 4 in Landscape (thin film)
Preventative Maintenance Required: None
Tracker Power Consumption: 31kWh per tracker/year or self-powered
Certifications: UL 2703 (2018) Key Features:
• Adaptable with crystalline or thin film, optimized for 1000V and 1500V modules and installation is easy with no prying, adjusting, or special tools;
• Self powered option now available, and independently driven rows provide easy access for mowing, cleaning, and other maintenance;
• Lower per-unit fixed costs for BOS savings; • Programmable technology to mitigate
inclement climatic conditions;
• Independent tables increase design flexibility to maximize land use;
• Smart backtracking reduces row shading to optimize energy production for high power density.
