Core Advantages: "Double Subversion" of Process Performance
Revolution in installation efficiency
Integrated bending process: The length of a single frame is 2.5 m (1.5 m in the tradition), and the installation speed of the module is increased by 50% (measured data of LONGi).
Splice-free design: 90% reduction in corner code/bolt connection points, and $0.05/W reduction in labor costs.
Structural performance jumps
Wind pressure enhancement: The stiffness of the continuous frame structure is increased by 25%, and it has passed the IEC 61215 mechanical load test (5400Pa).
Upgraded sealing: IP68 waterproof grade (DIN 40050-9), suitable for high-pressure environments of double-glass modules.
Economic and environmental friendliness
Lightweight and weight reduction: The density is 2.72g/cm³, which is 65% lighter than the steel frame and 30% lower transportation cost (saving $1500 per MW).
Zero-carbon aluminum: hydropower aluminum accounts for ≥80% (carbon footprint< 1.5tCO₂e/ton) to avoid EU CBAM carbon tariffs.
International application scenarios
1. Large-scale ground power stations
Middle East Desert Photovoltaic Farm (ACWA Power, Saudi Arabia): 2500mm aluminum coil integrated bending frame, anti-sand and dust wear (Mohs hardness ≥3), installation speed of 1MW/day (traditional process 0.6MW), shortened construction period by 40%.
First Solar, California, USA: Wind pressure resistance of 60m/s (UL 2703 certification), no splicing joint design reduces leakage points by 95%, and power generation efficiency is increased by 7%.
2. Distributed PV and BIPV
European industrial and commercial roofs (IBC Solar, Germany): lightweight frame (1.5mm thick) reduces the load-bearing capacity by 35%, adapts to old factories (EN 1991-1-1 standard), and shortens the payback period of the project to 5 years.
Japanese residential photovoltaic tile (Panasonic HIT): curved surface integrated bending technology, roof integration increased by 90%, zero damage record in typhoon season.
3. Offshore floating power stations
China Coastal Floating Project (Three Gorges Energy): salt spray > 5000 hours (ISO 9227), 2500mm width reduces connectors by 80%, and maintenance costs are reduced by 50%.
Norwegian Fjord Power Station: -30°C low temperature impact toughness (ISO 148-1), ice floe impact resistance, extended service life up to 30 years.
Future Trends: The "Technology Frontier" of Ultra-Wide Aluminium Coil
1. Breaking through the width limit
2800mm R&D: Adaptable to 2300mm ultra-large modules (LONGi Hi-MO 7), cutting loss reduced to 0.5% (mass production in 2025).
Tailored laser welding technology: local widening to 3500mm to meet the integration requirements of double-row modules (JinkoSolar experimental line).
2. Intelligent bending system
AI real-time compensation: Vision sensors dynamically correct bending angles (KUKA robot solution) with an accuracy of ±0.1°.
Digital twin pre-installation: virtual simulation of frame stress distribution (Dassault 3DEXPERIENCE) with a first-time installation pass rate of > 99.9%.
3. Green material upgrades
Closed-loop recycled aluminum: The direct melting recycling rate of scrap aluminum > 95% (Hydro CIRCAL technology), and the cost is reduced by 15%.
Perovskite module adaptation: moisture-resistant coating (water and oxygen transmittance <10⁻⁵g/m²·day), compatible with next-generation photovoltaic technology.
4. Application scenario revolution
Space photovoltaic power station: radiation-hardened aluminum (NASA certification), low earth orbit service life > 10 years (SpaceX Starlink program).
Movable photovoltaic system: folded frame design, deployment speed increased by 80% (U.S. military field energy project).
