Features at a Glance

Key components: Monocrystalline silicon cells, tempered glass surface, waterproof junction box, aluminum alloy frame, MC4 connectors.

Installation Guidelines

Unpack and inspect panel for damage. Ensure all components are present.

1. Choose location: Select area with maximum sunlight exposure, minimal shading.
2. Mounting structure: Use corrosion-resistant rails or brackets rated for panel weight.
3. Orientation: Tilt angle optimized for geographic latitude (typically 15-45 degrees).
4. Secure panel: Use provided bolts and clamps; do not overtighten.
5. Grounding: Connect frame to proper earth ground for lightning/surge protection.

WARNING! Panel is heavy; use two people for handling. Avoid contact with live electrical parts during installation.

Mounting Instructions

Use appropriate mounting hardware (not included).

1. Roof Mount: Use Z-brackets or rail system; ensure roof integrity and waterproofing.
2. Ground Mount: Use adjustable ground mounts; secure with concrete footings if needed.
3. Pole Mount: Use appropriate pole adapter kits.
4. Spacing: Maintain minimum 10mm gap between panels for ventilation.
5. Wind/Snow Load: Rated for 2400Pa wind load and 5400Pa snow load.

CAUTION! Do not drill into panel frame beyond mounting holes. Avoid shading from objects.

Wiring & Connections

Use UV-resistant PV cable (4mm² recommended) and MC4 connectors.

1. Series Connection: Connect positive (+) of one panel to negative (-) of next to increase voltage.
2. Parallel Connection: Connect all positives together and all negatives together to increase current.
3. Combiner Box: Use for multiple parallel strings with fuses/breakers.
4. Charge Controller: Connect to appropriate MPPT or PWM controller matching system voltage.
5. Polarity: Double-check positive/negative connections before making final connections.

Tip: Cover panel surface during wiring to prevent electrical shock from generated power.

System Configuration

Compatible with 12V, 24V, or 48V battery systems via appropriate charge controller.

1. For 12V system: 1 panel with MPPT controller (Vmp > battery voltage).
2. For 24V system: 2 panels in series or 1 panel with appropriate MPPT controller.
3. For 48V system: 4 panels in series or multiple strings with combiner box.
4. Battery Bank: Use deep-cycle batteries (AGM, Gel, Lithium) with proper capacity.
5. Inverter: Select pure sine wave inverter matching system voltage and power requirements.

WARNING! Always use properly rated overcurrent protection (fuses/breakers) between panels and charge controller.

Performance & Efficiency

Optimal performance requires proper installation and maintenance.

1. Sunlight Hours: Output varies with solar irradiance (peak sun hours).
2. Temperature: Efficiency decreases as temperature increases above 25°C.
3. Shading: Even partial shading can significantly reduce output; use micro-inverters or optimizers if shading unavoidable.
4. Angle Adjustment: Seasonal tilt adjustment increases annual energy yield.
5. Monitoring: Use charge controller display or external meters to track performance.

Expected Daily Output: 280W × Peak Sun Hours (e.g., 4 hours = 1120Wh daily).

Maintenance & Cleaning

Regular maintenance ensures optimal performance and longevity.

1. Cleaning: Use soft cloth or sponge with mild soap and water. Rinse with clean water.
2. Frequency: Clean every 3-6 months, or more frequently in dusty/polluted areas.
3. Inspection: Check for cracks, corrosion, loose connections, and vegetation shading.
4. Tightening: Inspect mounting hardware and electrical connections annually.

CAUTION! Do not use abrasive materials or harsh chemicals. Clean during cool morning/evening hours to avoid thermal shock.

Safety Precautions

Solar panels generate DC electricity whenever exposed to light.

• Electrical Safety: Treat panels as live electrical source; wear insulated gloves during installation.
• Fire Safety: Keep flammable materials away from panel and wiring.
• Fall Protection: Use proper safety equipment when working at heights.
• Disposal: Recycle according to local regulations; do not dispose in regular trash.
• Children/Pets: Keep away from installation area during work.

Emergency Shutdown: Cover panels completely to stop power generation if needed.
