- Insufficient Terrain Adaptability:Â Traditional steel and aluminum structures are difficult to install on irregular terrains such as slopes, hills, and ponds.
- Limited Wind Resistance:Â Traditional designs pose safety hazards in typhoon-prone areas.
- High Material Consumption:Â Extensive use of steel leads to increased carbon emissions, which contradicts the environmental philosophy of renewable energy.
- Low Installation Efficiency:Â Traditional systems require substantial on-site labor, resulting in excessively high labor costs.
The Qierjie Solar Flexible Mounting System employs a design philosophy combining pre-stressed cable structures with lightweight composite materials. Through systematic technological innovation, it achieves comprehensive breakthroughs in performance, cost-effectiveness, and adaptability for photovoltaic mounting solutions. The system comprises a high-strength flexible cable net, adaptive connectors, intelligent tensioning devices, and a dedicated anchoring system, forming an integrated load-bearing framework.
Revolutionary Structural Design
The core innovation of Qierjie’s flexible mounting system lies in its unique spatial cable-net structure:.
Bidirectional Pre-stressing System: Longitudinal load-bearing cables and transverse stabilising cables form a spatial grid, distributing loads uniformly.
Life-Cycle Economic Analysis
Over a 25-year operational cycle, the Chiljer Flexible Mounting System delivers significant economic benefits:
- Initial Investment Savings: Land costs reduced by 20%–40%, foundation engineering savings of 30%–50%
- O&M Cost Advantage: Simplified cleaning and maintenance, reducing annual O&M expenses by 15%–25%
- Power Generation Gains: Optimized ventilation conditions, improving system efficiency by 3%–8%
- Residual Value Recovery: Dismantlable design with material recovery rates as high as 90%
Comprehensive calculations show that adopting the Chiljer Flexible Mounting System can reduce the Levelized Cost of Electricity (LCOE) by 0.08–0.12 RMB/kWh and increase the Internal Rate of Return (IRR) by 1.5–2.5 percentage points.
