Precision CNC Anodized Aluminum Corner Joints for Solar Panel
Frames
Product Overview:
Our Precision CNC Anodized Aluminum Corner Joints are engineered to
provide superior structural integrity and corrosion resistance for
solar panel frames. Manufactured using high-grade 6063/6005
aluminum alloy and processed with CNC machining, these corner
joints ensure tight tolerances (±0.15mm), durability, and seamless
assembly for photovoltaic (PV) modules. The anodized surface
treatment enhances weather resistance, making them ideal for harsh
outdoor environments
Key Features:
Material: 6063-T5 / 6005-T6 aluminum alloy (high strength-to-weight
ratio)
Precision Machining: CNC-milled for ±0.15mm tolerance, ensuring
perfect alignment
Surface Treatment: Anodized (10-25μm thickness) for corrosion & UV
resistance
Compatibility: Fits standard 30mm/35mm/40mm solar frame profiles
Load Capacity: Supports high wind/snow loads due to reinforced
design
Applications of CNC Machining in Solar Energy:
CNC machining is critical in solar panel manufacturing, enabling:
1. High-Precision Frame Components
CNC-machined aluminum extrusions for solar frames ensure ±0.5mm
length tolerance, crucial for panel stability.
Corner joints, mounting brackets, and rail splices are CNC-drilled
for seamless assembly.
2. Solar Tracking Systems
CNC-produced gearboxes, shafts, and brackets for solar trackers
ensure accurate sun-following motion.
3. Heat Exchangers & Micro-Machining
CNC-machined aluminum heat sinks optimize thermal management in
solar panels.
Laser-cut silicon wafers with micron-level precision enhance PV
cell efficiency.
Comparison with Traditional Corner Joints:
Aspect | Precision CNC Anodized Aluminum Corner Joints | Traditional Corner Joints |
Precision | Tight tolerances achieved through CNC machining for perfect
alignment. | Less precise, may lead to assembly issues. |
Corrosion Resistance | Superior resistance due to anodized aluminum. | Prone to corrosion in harsh environments. |
Aesthetics | Attractive anodized finish. | Often lack a refined appearance. |
Long - term Performance | Consistent performance over time with minimal degradation. | May deteriorate more quickly, requiring frequent replacement. |
Case Studies:
1. Commercial Solar Installation in Coastal Area: In a commercial solar installation near the coast, where salt -
laden air is a significant corrosive factor, our Precision CNC
Anodized Aluminum Corner Joints were used. Traditional joints would
have corroded rapidly, but our anodized aluminum joints maintained
their structural integrity and appearance even after years of
exposure to the harsh coastal environment. This led to reduced
maintenance costs and ensured the continuous operation of the solar
panels.
2. Residential Rooftop Solar Project: In a residential rooftop solar project in an area with frequent
rain and temperature fluctuations, the high precision of our CNC -
machined corner joints enabled quick and accurate installation. The
durability of the anodized aluminum material also meant that the
joints could withstand the changing weather conditions without
developing cracks or weakening, providing homeowners with a
reliable and long - lasting solar panel setup.
