Safety Precautions

Photovoltaic modules produce DC electricity when exposed to light, which presents electrical shock and fire hazards. Always follow these safety rules.

Hazard	Precaution
Electrical Shock	Cover modules with an opaque material during installation and wiring. Use insulated tools and wear appropriate PPE (gloves, safety glasses).
Fire Hazard	Do not install near flammable gases or materials. Ensure all electrical connections are tight and comply with local codes.
Mechanical Injury	Modules are heavy and have sharp edges. Use proper lifting techniques and wear cut-resistant gloves. Install with at least two people.
Arc Flash	Do not disconnect under load. Ensure system is de-energized before working on DC or AC circuits.

WARNING! Installation should only be performed by qualified personnel in accordance with all applicable local, regional, and national electrical and building codes.

Installation Planning

Proper planning ensures optimal performance and system longevity.

Site Assessment: Ensure the installation site has no shading (trees, chimneys) during peak sun hours (9 AM - 3 PM). Assess roof/ground structural integrity.
Orientation & Tilt: For maximum annual yield in the Northern Hemisphere, orient modules true South. Optimal tilt angle is typically equal to the site's latitude.
Spacing: Maintain minimum spacing between rows to avoid inter-row shading. Follow mounting system manufacturer's guidelines.
Tools & Materials: Prepare insulated tools, torque wrench, multimeter, appropriate mounting hardware, and DC cabling.

CAUTION! Never drill into the module frame or glass. This will void the warranty and compromise safety.

Mechanical Installation

Modules must be securely mounted using a certified mounting system compatible with the module frame.

Mounting System: Use only Jinko-approved or certified mounting systems (e.g., clamps, rails).
Clamp Placement: Attach clamps to the long frame sides only, within the marked clamping zones (typically 200-300mm from module ends). Use mid-clamps between modules.
Torque Specifications: Tighten all bolts to the mounting system manufacturer's specified torque (typically 20-30 Nm). Overtightening can damage the frame.
Wind/Snow Load: Ensure the mounting configuration meets local wind and snow load requirements as per IEC 61215.
Ground Clearance: Maintain a minimum clearance of 10cm between the module rear and the mounting surface for ventilation.

WARNING! Do not stand or walk on the modules. Do not apply any concentrated loads to the glass surface.

Electrical Installation

Correct electrical wiring is critical for safety and performance.

String Configuration: Calculate the maximum number of modules in series based on the inverter's maximum DC input voltage and the module's Voc at the lowest expected ambient temperature.
Connecting Modules: Use the provided MC4 compatible connectors. Ensure they are fully engaged and hear a "click". Weatherproof all connections.
Polarity: Double-check polarity (+ to +, - to -) before making final connections. Incorrect polarity can damage the inverter.
Grounding: The module frame MUST be grounded according to local electrical codes, typically using a dedicated grounding lug on the frame.
Cable Management: Secure cables to the mounting rails using UV-resistant cable ties. Avoid sharp bends and ensure cables do not touch the roof surface.

Tip: Label all DC strings at the combiner box for easy identification during maintenance.

System Commissioning

Final checks before energizing the system.

Visual Inspection: Check for physical damage, secure mounting, proper cable routing, and intact junction boxes.
Electrical Tests: Use a multimeter to measure:
- Open-Circuit Voltage (Voc): Should match calculated string voltage (±5%).
- Short-Circuit Current (Isc): Measure under full irradiance, should be near STC Isc.
- Insulation Resistance: Should be >1 MΩ per local standards (e.g., IEC 62446).
Inverter Startup: Follow the inverter manufacturer's instructions to power on the system. Monitor initial operation for errors.

Operation & Maintenance

Minimal maintenance is required for optimal performance.

Cleaning: Clean glass surface with water and a soft cloth or sponge if soiling (dust, pollen, bird droppings) reduces output. Do not use abrasive materials or harsh chemicals.
Inspection: Perform periodic visual inspections for damage, loose connections, corrosion, or vegetation shading.
Monitoring: Regularly check system performance via the inverter monitoring platform to detect any significant output drops.
Snow: Do not use sharp tools to remove snow. It will usually slide off on its own due to the smooth glass and tilt angle.

CAUTION! Never spray cold water on hot modules, as thermal shock can crack the glass.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No/Reduced Power Output	Shading, soiling, faulty connection, inverter issue.	Check for shading/soiling. Inspect all connectors and cables. Verify inverter status and error codes.
Hot Spot on Module	Cell mismatch, partial shading, or internal defect.	Identify and remove shading source. If hot spot persists, the module may be defective - contact Jinko support.
Ground Fault Alarm	Insulation failure, water ingress, damaged cable.	De-energize system. Use a megohmmeter to locate the fault. Check junction boxes for moisture.
Module Cracked or Delaminated	Physical impact, thermal stress, manufacturing defect.	Stop using the module. Isolate it electrically. Contact Jinko for a warranty claim assessment.
High String Voltage/Current Error	Incorrect string configuration, temperature miscalculation.	Re-calculate max string size for lowest site temperature. Reduce the number of modules in the string if necessary.
