Solar PV Wiring & BOS
UV-Resistant, Long-Life Cabling for Utility-Scale Solar Installations
Utility-scale solar plants operate for decades in UV-exposed, high-temperature, dusty, and wind-loaded environments. The Balance of System (BOS)—DC string wiring, AC collection, grounding, communications, and monitoring—must deliver long-term electrical reliability while minimizing O&M costs.
Farsince provides a Solar PV Wiring & BOS Solution engineered to protect signal integrity and power delivery across the full lifecycle of energy & low-voltage projects—from array field to inverter stations and plant control rooms.
Solution Overview
Built for Sun, Heat, and Time
Farsince’s solar BOS strategy focuses on three essentials:
- UV & Weather Resistance – Materials and jackets designed for continuous outdoor exposure
- Electrical Stability – Low loss, consistent insulation performance under heat
- System Scalability – Structured wiring that supports expansion and monitoring upgrades
This solution is ideal for utility-scale PV plants, solar farms, agrivoltaics, and large commercial arrays.
Solar PV Wiring & BOS Architecture
1. PV Array Field (DC Power Layer)
The most exposed section of the plant, directly under sun and weather:
- PV Solar Cables – UV-resistant, halogen-free insulation for long-term DC string connections
- Ruggedized & Waterproof Cables – Protection against abrasion, moisture, and temperature cycling
- Cable Management – Organized routing to reduce mechanical stress and shading impact
These components ensure stable DC power collection with minimal degradation over time.
2. Inverter & Combiner Station Wiring (AC & Control)
Where DC is converted and aggregated:
- Electrical / Power Cables – Reliable AC power transmission from inverters to transformers
- Fieldbus Cables – Deterministic communication for inverter control and diagnostics
- Panel Mount Cables & Waterproof Connectors – Secure, sealed interfaces inside outdoor enclosures
This layer supports safe power conversion and real-time operational control.
3. Plant Monitoring & Communication Network
Modern solar plants rely on data for performance optimization and fault detection:
- Industrial Ethernet Cables – Stable communication between inverters, sensors, and SCADA systems
- Fiber Optic Cables & Trunk Cables – Long-distance, EMI-immune links across large sites
- Fiber Distribution Frames (ODF) – Structured fiber management at control rooms and substations
- Fiber Tools – Installation validation and maintenance to keep optical loss within budget
4. Infrastructure & Low-Voltage Support
A reliable BOS requires organized physical infrastructure:
- Cabinets – Outdoor-rated enclosures for power and communication equipment
- PDUs – Stable power distribution for monitoring and control devices
- Access Control & Lighting Control Cables – Support for site security and night operations
- Network Testers & Tools – Commissioning, acceptance testing, and preventive maintenance
