Installation

Unpack and inspect contents. Ensure mounting surface is clean and dry.

Choose location: Select area with maximum sunlight exposure, avoiding shadows.
Mount panel: Use provided grommets and adhesive/straps for secure attachment.
Connect cables: Attach MC4 connectors to corresponding cables (positive to positive, negative to negative).
Route wiring: Secure cables away from sharp edges and potential damage.

WARNING! Do not install during rain or high winds. Ensure all electrical connections are dry before making contact.

First-Time Setup

Connect to charge controller or power system; verify operation.

Connect to charge controller: Attach panel outputs to controller's solar input terminals.
Verify polarity: Ensure positive (red) and negative (black) connections are correct.
Check voltage: Use multimeter to confirm open-circuit voltage matches specifications.
Secure connections: Weatherproof all connectors with provided caps or sealant.

CAUTION! Never connect panel directly to battery without charge controller to prevent damage.

Controls and Connections

No active controls on panel. All management through connected charge controller.

Connections: MC4 connectors (male/female) for positive and negative terminals. Junction box with bypass diodes for partial shade protection.

Monitoring: Check charge controller display for voltage, current, and power output. Some models include LED indicator in junction box for connection status.

Connecting to Power Systems

For 12V systems: Connect directly to compatible MPPT or PWM charge controller. For higher voltage: Connect multiple panels in series (positive to negative) to increase voltage.

Turn off all connected equipment before making connections.
Connect panels: Use MC4 branch connectors for parallel/series configurations.
Connect to controller: Ensure controller rating matches panel array voltage/current.
Connect controller to battery: Follow controller manual for proper battery connection.

Tip: Use appropriate gauge wiring to minimize power loss over distance.

Operation and Monitoring

Panel operates automatically when exposed to light. No user intervention required.

Daily check: Ensure panel surface is clean and free of obstructions.
Monitor output: Check charge controller readings regularly for expected performance.
Seasonal adjustment: Tilt angle can be adjusted for optimal seasonal sun exposure.
Shading avoidance: Keep entire panel surface unobstructed for maximum output.

WARNING! Do not attempt to disconnect under load. Cover panel with opaque material or disconnect at controller first.

Maintenance & Storage

Clean periodically with soft cloth and water. Store properly when not in use.

Cleaning: Use mild soap solution and soft cloth. Rinse with clean water.
Inspection: Check for physical damage, loose connections, or discoloration.
Storage: Keep in dry, cool place away from direct sunlight when not installed.
Long-term storage: Store flat or rolled with protective layer between surfaces.

CAUTION! Do not use abrasive cleaners or high-pressure water. Do not fold sharply beyond specified bend radius.

Safety Information

Electrical hazard: Panel produces DC voltage whenever exposed to light, even dim light.

Always wear insulated gloves when working with electrical connections.
Disconnect at charge controller before servicing panel connections.
Do not install near flammable gases or materials.
Keep children and pets away from installation area.
Follow all local electrical codes and regulations.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No power output	Shading, dirty surface, connections	Clean panel surface; check all connections; ensure no shading.
Low power output	Cloudy weather, incorrect angle	Adjust tilt angle; check for partial shading; verify controller settings.
Physical damage	Impact, bending beyond limit	Inspect for cracks or delamination; contact support if damaged.
Overheating	Poor ventilation, high ambient temperature	Ensure rear ventilation; avoid dark mounting surfaces that retain heat.
Water ingress	Damaged seals, improper installation	Check junction box seals; ensure MC4 connectors fully engaged and sealed.

Reset: Disconnect and reconnect all connections starting from charge controller.
