An aluminum alloy tripod ballast system is a non-penetrating mounting solution designed primarily for flat or low-slope roofs. Its defining feature is the triangular support structure (often referred to as an A-frame or tripod) constructed from high-strength aluminum alloy profiles, which provides a stable, elevated platform for solar modules while incorporating integrated features for ballast containment .

Core Functional Principles

• Non-Penetrating Attachment: The system relies entirely on gravitational ballast—typically concrete blocks, pavers, or gravel placed in integrated trays or on base beams—to resist wind uplift and sliding forces. This eliminates any roof penetrations, preserving the integrity and warranty of the waterproofing membrane .

• Triangular Structural Efficiency: The tripod (triangular) geometry is inherently stable and efficient. It distributes wind and snow loads through the frame and down to the roof surface via three primary contact points, minimizing stress on individual components .

• Optimized Tilt Angle: The height differential between the front and rear legs creates an elevated tilt angle (typically 5° to 15° for flat roofs, up to 30° or more for higher yield) that maximizes solar energy production .

• Modular, Scalable Design: Multiple tripod units can be connected in rows using mounting rails, allowing arrays of any size to be configured and easily expanded .

Geometric Configuration: The Aluminum Tripod

The defining feature is the triangular frame structure:

• Front Leg (Lower): The shorter vertical or angled support positioned at the lower edge of the array. It determines the minimum elevation of the panels above the roof .

• Rear Leg (Higher): The taller support positioned at the upper edge, creating the tilt angle. It may be fixed or adjustable to vary the angle .

• Base Beam / Horizontal Member: The bottom member connecting the front and rear legs, completing the triangular structure. This member often incorporates features for ballast retention
