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
