Rooftop PV Aluminum Frame

Where residual roof load capacity is limited, the self-weight of the modules and mounting system must be assessed as a whole.

With many roof types, clamps, rails, and hold-downs in use, the frame must be matched precisely to the mounting system.

Restricted installation space means repeated drilling, adjustment, and rework at height increase both cost and safety risks.

Precision Corners

Lightweighting must be based on structural calculations and module certification; critical load-bearing areas must not simply be thinned.

Drainage-Hole Design

Prefabricated grounding and mounting holes must match the electrical design and clamping system to avoid arbitrary on-site drilling.

Surface Texture

Coordinate drainage holes with the roof slope to reduce standing water, dust accumulation, and frost-heave risks in the slots.

Q1:  Is a lightweight frame better simply because it is lighter?

A: No. Lightweighting must remain within the limits of strength, stiffness, connection reliability, and module certification. Critical load-bearing areas must not be thinned arbitrarily.

Q2:  Can the frame guarantee that the roof will not leak?

A: No. Roof waterproofing depends on clamps, rails, penetrations, sealing, and workmanship. The frame only provides the module's perimeter structure and mounting interface.

Q3: Can additional mounting holes be drilled freely on site?

A: This is not recommended. On-site drilling may affect strength, drainage, grounding, and warranty coverage. Holes should be prefabricated to approved drawings or confirmed by the designer.
