Features at a Glance

Key components: Monocrystalline solar cells, Anodized aluminum frame, Tempered glass, Junction box with bypass diodes, MC4 connectors, Mounting holes.

Installation

Unpack and inspect contents. Ensure all components are present and undamaged.

1. Choose location: Select area with maximum sunlight exposure, minimal shading.
2. Mounting: Secure mounting brackets to roof or ground structure using provided hardware.
3. Attach panel: Place panel onto brackets and secure with bolts.
4. Grounding: Connect grounding wire to frame grounding point.
5. Electrical connection: Connect panels in series/parallel using MC4 connectors as per system design.

WARNING! Installation should be performed by qualified personnel. Use proper safety equipment. Do not install during inclement weather.

First-Time Setup

After physical installation, configure electrical connections.

1. Verify connections: Ensure all MC4 connectors are securely mated and waterproof seals intact.
2. Connect to inverter: Route DC cables to inverter input terminals following polarity markings.
3. System check: Turn on inverter and monitor for proper voltage/current readings.
4. Monitor setup: Configure monitoring system (if applicable) to track panel performance.

CAUTION! DC electricity can be dangerous. Ensure all connections are correct before energizing system.

Controls and Monitoring

Panel itself has no active controls. System monitoring through inverter or external monitoring device.

Inverter Interface: Displays DC voltage, current, power, and energy production.

Monitoring Options: Web portal, mobile app, or display unit showing real-time and historical data.

Performance Indicators: Daily energy yield, peak power, system efficiency, and fault alerts.

Connecting to System

Series Connection: Connect positive of one panel to negative of next to increase voltage. Parallel Connection: Connect all positives together and all negatives together to increase current.

1. Turn off all system components before making connections.
2. Use proper gauge cables rated for outdoor use and system current.
3. Ensure polarity is correct (positive to positive, negative to negative).
4. Use weatherproof conduit and cable management.

Tip: Label all cables for easy identification during maintenance.

Performance Optimization

Maximize energy production through proper orientation and maintenance.

1. Orientation: Face true south (northern hemisphere) or true north (southern hemisphere).
2. Tilt angle: Set angle equal to latitude for year-round optimization.
3. Cleaning: Regularly clean surface to remove dust, pollen, and debris.
4. Shading avoidance: Trim vegetation and remove objects that cast shadows.
5. Monitoring: Regularly check performance data for deviations indicating issues.

WARNING! Never walk on panels. Use proper safety equipment when cleaning or inspecting.

Safety Features

Bypass Diodes: Minimize power loss from partial shading. Frame Grounding: Provides path for lightning and surge protection. IP67 Rating: Protects against dust and water ingress. Fire Rating: Class C fire resistance.

Care & Maintenance

Regular inspection and cleaning ensure optimal performance.

1. Visual inspection: Check for physical damage, corrosion, or loose connections quarterly.
2. Cleaning: Use soft brush and water; avoid abrasive materials or high-pressure spray.
3. Connection check: Verify MC4 connectors are secure and weather seals intact annually.
4. Professional inspection: Schedule comprehensive inspection every 3-5 years.

CAUTION! Do not use chemicals or detergents. Clean early morning or late evening when panels are cool.
