Desert PV Aluminum Frame

Abrasion-Resistant Surface Selection

Prioritize a uniform, dense anodic coating. Evaluate AA15 to AA20 based on wind-and-sand severity and the maintenance method.

Low-Sand-Accumulation Section

Minimize unnecessary horizontal sand-collecting surfaces and enclosed dead zones, coordinating sand outlets, drainage holes, and installation orientation.

Thermal-Cycle Compatibility

Control length, angles, hole positions, and assembly clearances to reduce internal stress and connection-loosening risks during thermal cycling.

Precision Corners

Natural anodizing may be prioritized for evaluation in high-temperature environments; black surfaces must be confirmed against module temperature rise and appearance requirements.

Drainage-Hole Design

Keep slots and sand outlets burr-free to prevent trapped sand and damage to sealing materials

Surface Texture

Provide appropriate assembly clearance at corner connections to accommodate dimensional changes during thermal cycling.

Sampling Inspection of Coating Thickness, Appearance, and Abrasion Resistance

High-/Low-Temperature and Thermal-Cycle Validation

Sand/Dust Ingress and Sand/Water Drainage Inspection

Capacity

Global 125GW Annual Capacity

Customization

Support for Various Length and Cross-section Designs Based on Client Drawings

Packaging

Export-standard Protective Packaging to Prevent Deformation During Sea Freight

Q1: Do desert frames simply need to be made thicker?

A:  No. The section should be optimized for the support span, mounting method, and wind load. Increasing thickness without analysis adds cost and weight.

Q2:  Can black frames be used in desert environments?

A: Yes, but dark surfaces may absorb more heat. Their suitability should be validated against the module temperature class, ventilation conditions, and appearance requirements.

Q3: Can a sand-and-dust test prove the service life of an entire PV plant?

A: No. Environmental testing helps identify weak points; it does not constitute a quantitative service-life guarantee for a specific project.
