Foshan Shishi New Energy Photovoltaic Power Generation System
Foshan Shishi New Energy
The Foshan Shishi New Energy Photovoltaic Project was completed and accepted for power in February 2024. Yanghua Kechuang's 1600A high-current flexible busbar was deployed at the access section of the photovoltaic power generation system. At three outdoor turn points along the cable route, the flexible busbar achieved direct bending without the need for additional joint boxes or elbow connectors. The point-to-point connection and integrated product laying method reduced the number of joints required, significantly improving the safety and stability of system power supply while reducing both material and construction costs, achieving an overall cost reduction of 10%. The Datang Town Industrial Park leverages abundant factory rooftop space for distributed photovoltaic construction, contributing to a park-wide PV promotion rate of 42% with 139,711 kWp installed capacity.
Project Background & Challenges
The outdoor cable route featured three sharp turns that would normally require joint boxes or elbow connectors, increasing cost and introducing potential failure points. The project required a solution that could navigate turns without joints while maintaining high current capacity.
- Three outdoor turns in the cable route required either joint boxes or specialized elbow fittings with conventional rigid busbar systems
- Each intermediate joint represented a potential hotspot and failure point under sustained 1600A loading conditions
- Traditional solutions at each turn point added significant material and labor costs for joint fabrication and waterproofing outdoors
- The project needed to meet stringent safety and stability requirements for continuous power supply to the PV system
Solution
Yanghua deployed a 1600A high-current flexible busbar capable of achieving direct bends at all three outdoor turn locations, using a point-to-point integrated laying approach that eliminated intermediate joints entirely.
- Utilized 1600A high-current flexible busbar with inherent bending capability to negotiate three outdoor turns without any joint accessories
- Implemented point-to-point connection topology from the PV array to the grid-connection cabinet, simplifying the entire power path
- Leveraged the integrated insulation and weather-resistant construction of flexible busbar for direct outdoor routing without additional protective conduit
- Achieved single-piece continuous busbar runs that enhanced overall system safety by eliminating intermediate connection weak points
