Product Description

Product Description

Factory Direct | Durable Aluminium Frame | Roof Mounting System
Designed for industrial, commercial and residential areas, the lightweight single-axis solar racking system uses high-purity aluminium frames (tensile strength ≥270MPa) and modular mounting technology to fit rooftop photovoltaic projects. The system improves power generation efficiency by 25%-35% through intelligent tracking technology (±45° dynamic adjustment) and offers a 10-year warranty on the main structure, helping customers achieve clean energy transformation.

Core Parameters.

Material: 6063-T5 aluminium alloy + anti-corrosion coating (passed ASTM B117 salt spray test ≥ 2000 hours)
Load capacity: 5 tonnes for single bracket, compatible with double-sided modules/182mm/210mm size
Protection: IP65 motor + wind pressure resistant design (wind load ≥100km/h)
Adjustment range: ±45° dynamic tracking + 10°-50° manual tilt adjustment
Key Advantages

1. Light weight and high strength design

The density of aluminium is only 2.7g/cm³, which is 40% lighter than steel bracket, reducing the load pressure on the roof.
The frame adopts triangular reinforcement structure, which increases the bending rigidity by 50% and is suitable for complex roofs with slopes ≤ 30°.

2. Corrosion resistance and environmental compliance

Triple protective coating: hot dip galvanised base coat + epoxy primer + polyurethane top coat, acid and alkali (pH 2-12) and UV aging resistant.
RoHS 2.0 certified: All materials are free of lead, cadmium and other harmful substances, complying with EU export standards.

3. Intelligent Installation and Efficient Operation and Maintenance

Pre-assembled design: 90% factory prefabrication rate, 50% reduction in on-site assembly time, daily installation capacity ≥ 5MW.
Low Maintenance Cost: Annual O&M cost <0.5% of power generation revenue, support remote monitoring and fault warning.

4. Compatibility and Expandability

Supports linkage with energy storage systems, microgrids, and adapts to PERC/HJT/Calcite technology.
Adjustable rail spacing up to 30-80mm, compatible with different brands of inverters (e.g. Huawei, SMA).

 Installation & Maintenance Guide
Installation Steps

Roof Survey.
Use laser range finder to check the roof loading ≥150kg/m², slope error ≤5°.
Bracket assembly.
Main beam bolt tightening torque 65N-m±5%, rail installation error ≤1mm.
System Integration.
Installation of IP65 protection motor and light sensor, calibration of initial inclination angle (accuracy ±0.5°).
Maintenance recommendations

Monthly inspection.
Clean the guide rail for dust accumulation, check the coating scratches (partial repair ≤ 3mm).
Tighten bolts with anti-loosening marks and lubricate the guide rails (lithium grease NLGI grade 2).
Annual maintenance.
Replace drive bearings (-40ºC~85ºC resistant grease), update control software.
Use coating thickness gauge to check zinc layer thickness (localised ≥60μm need to be re-coated).

 

Applications
Industrial and Commercial Rooftops: Distributed power generation for factories, warehouses and commercial complexes, suitable for highly polluted environments.
Residential PV: Compatible with sloped roofs and support access to home energy storage systems.
International assistance projects: CE/RoHS certification helps to enter the European, American and Southeast Asian markets.
Temporary power scenarios: Emergency disaster relief, temporary camps and other rapid deployment needs.

FAQ

 

Q1: What is the load-bearing capacity of the aluminium frame?

A: The single set of bracket has a load capacity of 5 tonnes and passed the IEC 62817 wind load test (wind speed ≥100km/h).

Q2: Does the system support double-sided modules?

A: Fully compatible! The backside gain is up to 20% and the height from the ground is adjustable from 1.5m-3m.

Q3: How to ensure anti-corrosion performance in coastal areas?

A: Triple protective coating design, laboratory tests show that the life expectancy in salt spray environment is ≥25 years.

Q4: What is the delivery cycle of 100MW project?

A: Standardised production + regional warehousing, 100MW project only takes 8-12 weeks from order to grid connection.

Q5: How to deal with deformation problem during the warranty period?

A: Free laser calibration service is provided and structural reset is completed within 24 hours.
