This document serves as the User Manual for Trina Solar's 166-cell Back Sheet-Glass Framed Modules, outlining essential information for their installation, maintenance, and safe operation.

Function Description:

The Trina Solar 166-cell Back Sheet-Glass Framed Modules are photovoltaic (PV) modules designed to convert sunlight into electricity. These modules are intended for use in solar energy systems, contributing to power generation. The manual emphasizes that installation and operation require specialized skills, and only professional personnel should handle the work. The modules can be connected in series to increase operating voltage or in parallel to increase current, allowing for flexible system configurations based on energy requirements.

Important Technical Specifications:

• Module Type: 166-cell Back Sheet-Glass Framed Module.
• Mechanical Load Bearing: The design loading of modules has been evaluated by TUV according to IEC61215 with a 1.5 times safety factor. The mechanical load bearing capacity is dependent on the mounting methods used.
  • 120 pcs Back Sheet-Glass Framed Module:
    • Mounting with Bolts: +3600 Pa / -1600 Pa (actual load +5400Pa/-2400Pa).
    • Mounting with Clamps: +3600 Pa / -1600 Pa (actual load +5400Pa/-2400Pa).
  • 144 pcs Back Sheet-Glass Framed Module:
    • Mounting with Bolts: +3600 Pa / -1600 Pa (actual load +5400Pa/-2400Pa).
    • Mounting with Clamps: +3600 Pa / -1600 Pa (actual load +5400Pa/-2400Pa).
    • Mounting with Single-axis Tracking System: +1600 Pa / -1600 Pa (actual load +2400Pa/-2400Pa). Mechanical Load Pressure under this method: 30 lbs.ft² max from the front side & 30 lbs.ft² max from the rear according to UL1703.
    • 2V Installation Method: +700 Pa / -700 Pa (Special Requirement, need confirm with Trina) (actual load +1050Pa/-1050Pa).
• Ambient Temperature Range: Recommended working ambient temperature of 20°C~50°C. Limit working ambient temperature range from -40°C to 85°C.
• Altitude: Maximum altitude less than or equal to 2000m.
• Output Cables: Stranded copper cables with a cross-sectional area of 4mm² (0.006in²), UV resistant, and suitable for direct sunlight exposure. Minimum bending radius of 43mm (1.69in).
• Connectors: Plug & play connectors.
• Fuse Rating: Typically 20A for maximum DC voltage in series with an array string. Actual module-specific rating can be found on the product label and datasheet.
• Grounding: All module frames and mounting racks must be properly grounded in accordance with appropriate National Electrical Code. Grounding conductor or strap may be copper, copper alloy, or other acceptable material. Grounding wire size (6 to 12 AWG solid bare copper) is specified for Tyco grounding bolts.
• Water Quality for Cleaning:
  • PH: 5~7
  • Chloride and Salinity: 0-3,000 mg/L
  • Turbidity: 0-30 NTU
  • Conductivity: 1500~3000 μs/cm
  • Total dissolved solids (TDS): ≤1000 mg/L
  • Water Hardness (calcium and magnesium ions): 0-40 mg/L

Usage Features:

• Installation Flexibility: Modules can be installed using mounting holes with bolts, clamps, or an embedded system on the frame. Specific mounting methods are detailed for different module types and orientations (portrait).
• Tilt Angle Optimization: Modules should be installed at an optimized tilt angle, typically not less than 10°, to maximize energy output. The ideal tilt angle is roughly equal to the project site's latitude, facing toward the equator.
• Site Selection: Modules should be positioned to minimize shading throughout the day and installed in a well-ventilated, waterproof, and dry place. Special considerations are given for installations in areas with high humidity, frequent lightning, or near the ocean.
• Safety Precautions: The manual emphasizes numerous safety precautions, including wearing dry insulation protection equipment, avoiding metallic jewelry, not installing in wet or windy conditions, and ensuring proper handling to prevent damage or electrical shock.
• Unpacking Procedures: Detailed steps for safe unpacking are provided, including checking product information, cutting packing belts, and handling modules by at least two persons.
• Storage Guidelines: Modules should be stored in their original packaging under dry and ventilated conditions. Specific stacking limits are provided for different module types (120-cell and 144-cell frame modules) in both project site warehouses and normal warehouses.
• Electrical Connections: Modules are connected in series to increase voltage or in parallel to increase current. Proper polarity must be observed to prevent damage to bypass diodes. All wiring must comply with local codes and international electrical standards.

Maintenance Features:

• Regular Visual Inspection: Modules in a PV array should be regularly checked for damage such as glass breakage, cable breakage, or junction box damage. A preventive inspection every six months is recommended.
• Cable and Connector Inspection: All cables and connections should be inspected to ensure they are tight, protected from direct sunlight, and away from water collection areas. Terminal bolt torque should be checked annually.
• Cleaning:
  • Frequency: PV modules should be cleaned when irradiance is below 200W/m².
  • Method: Use a soft cloth with mild detergent and clean water. Avoid severe thermal shocks, pressurized water exceeding 700 KPa, or steam cleaners. Do not spray water on the backside or cables.
  • Water Quality: Specific requirements for water quality (PH, chloride, turbidity, conductivity, TDS, and hardness) are provided to ensure effective and safe cleaning. Demineralized water is recommended if conditions permit.
  • Post-Cleaning Inspection: After cleaning, modules should be visually inspected for cleanliness, brightness, absence of stains, soot deposits, and proper support structure.
• Troubleshooting: If the installation does not work properly, users are advised to contact their installer or Trina Solar's after-sales service team.
• Module Replacement: Damaged modules should be replaced with the same type, following safety precautions such as covering the module surface with opaque material and isolating the affected array string.
