Installation

Unpack and inspect contents. Handle with care using proper PPE.

Mounting: Secure to compatible racking system using provided hardware.
Orientation: Position facing true south (northern hemisphere) at optimal tilt angle.
Spacing: Maintain minimum clearance for airflow and maintenance access.
Grounding: Connect frame to grounding system as per local electrical codes.
Electrical Connection: Connect panels in series/parallel per system design.

WARNING! Panels are heavy and fragile; use two people for handling. Install only in suitable weather conditions.

First-Time Setup

After installation, verify system connections before activation.

Visual Inspection: Check for physical damage, secure mounting, and clean surface.
Electrical Check: Verify all connections are tight and polarity is correct.
System Integration: Connect to charge controller/inverter following manufacturer instructions.
Initial Test: Monitor voltage and current output during first sunlight exposure.
Documentation: Record serial numbers and installation details for warranty.

CAUTION! Solar panels generate DC electricity when exposed to light. Cover panels during connection work.

Controls and Connections

No active controls on panel. Electrical connections via junction box.

Junction Box: Contains bypass diodes to minimize shading losses. Positive (+) and negative (-) terminals clearly marked.

Connectors: Standard MC4 type. Male/female connectors prevent reverse polarity connection.

Labels: Rating label on back shows electrical specifications, serial number, and certifications.

Connecting to System

Series or parallel connection depending on system voltage/current requirements.

Turn off all system components before making connections.
Connect panels using weatherproof MC4 connectors (click when fully engaged).
For series: Connect positive of one panel to negative of next panel.
For parallel: Use branch connectors or combiner boxes.
Route cables properly using clips; avoid sharp bends.
Final connection to charge controller/inverter per their manual.

Tip: Use appropriate gauge cables for current and distance to minimize losses.

Operation & Monitoring

Panels operate automatically when exposed to sunlight.

Daily Operation: No user intervention required after installation.
Performance Monitoring: Check via connected inverter monitoring system.
Seasonal Adjustment: Optional tilt adjustment for optimal seasonal performance.
Snow/Ice: Generally self-clearing due to smooth surface and tilt.
Shading: Minimize shading from trees, vents, or other obstructions.

WARNING! Do not attempt to disconnect under load. Always follow lockout/tagout procedures.

Safety Features

Bypass Diodes: Minimize power loss from partial shading. Frame Grounding: Provides path for fault current. Tempered Glass: Shatter-resistant. Fire Rating: Meets UL fire safety standards.

Care & Maintenance

Regular inspection ensures optimal performance.

Cleaning: Use soft brush and water only when cool. No abrasive materials or chemicals.
Inspection: Check quarterly for dirt, debris, bird droppings, physical damage.
Connections: Annual check for tightness and corrosion (by qualified personnel).
Vegetation: Trim nearby trees/plants that may cause shading.

CAUTION! Never spray cold water on hot panels. Work from ground when possible; use fall protection if roof access required.
