Installation & Setup

Unpack and inspect contents. Choose optimal location for solar exposure.

Unroll panel completely on flat surface or attach via grommets.
Position in direct sunlight: Angle toward sun for maximum efficiency.
Connect device: Use provided or certified USB cable to connect device to USB port.
Monitor LED: Status indicator should show charging activity.

WARNING! Do not bend panel sharply or puncture cells. Avoid shading portions of panel.

First-Time Use

For initial use, ensure proper orientation and connections.

Fully unroll panel on clean, dry surface in full sun.
Connect your device using appropriate USB cable.
Observe status LED: Solid or blinking light indicates charging.
Allow time for charging: Output varies with sunlight intensity.
Disconnect device when charged or when storing panel.

CAUTION! Do not look directly at sun when positioning panel. Keep panel away from extreme heat sources.

Solid Green/Blue: Panel receiving sunlight, device connected and charging.
Blinking Green/Blue: Charging in progress, lower light conditions.
No Light: Insufficient sunlight, no device connected, or panel fault.
Red Light/Blinking Red: Error condition (overcurrent, short circuit).

Physical Features: USB output port (sealed when not in use), attachment grommets, roll strap.

Connecting Devices

Compatible with most USB-powered devices using appropriate cables.

Ensure panel is in sunlight and device is powered off or in charging mode.
Connect one end of USB cable to device.
Connect other end to panel's USB output port.
Observe device charging indicator and panel status LED.

Tip: For best results, charge device while it is powered off. Some devices may charge slowly in bright sun.

Charging Operation

Optimize charging by managing sunlight exposure and device load.

Sunlight: Position panel perpendicular to sun's rays. Adjust every 1-2 hours.
Clean Surface: Wipe panel surface clean before use for maximum efficiency.
Avoid Shading: Even partial shading significantly reduces output.
Temperature: Output may decrease in very hot conditions.
Charging Time: Varies by device battery capacity and sunlight intensity.
Power Banks: Can be used to store solar energy for later use.

WARNING! Do not attempt to charge non-USB devices or modify output. Do not submerge panel in water.

Storage & Transport

Proper storage extends panel life and maintains performance.

Disconnect all devices and cables.
Clean panel surface with dry cloth (see Care & Cleaning).
Roll panel gently around core or as designed. Secure with strap.
Store in cool, dry place away from direct sunlight when not in use.
Transport in protective sleeve or case if provided.

CAUTION! Do not store with sharp objects. Avoid creasing or folding panel.

Care & Cleaning

Regular maintenance ensures optimal performance.

Unroll panel and disconnect any devices.
Use soft, dry cloth to wipe away dust and debris.
For stubborn dirt, dampen cloth with water only. Wipe gently.
Allow panel to dry completely before rolling for storage.
Inspect for damage to cells, substrate, or cables periodically.

CAUTION! Do not use chemicals, solvents, or abrasive cleaners. Do not spray water directly on panel or ports.

Troubleshooting

Symptom	Possible Cause	Corrective Action
No charging (LED off)	Insufficient sunlight, shading	Move to full, direct sun; remove any shadows covering panel.
LED on but device not charging	Faulty cable, device issue, low power	Try different USB cable; ensure device accepts 5V input; power off device and retry.
Intermittent charging	Cloud cover, moving shadows, loose connection	Reposition for consistent sun; check cable connections at both ends.
LED blinking red/error indication	Overcurrent, short circuit, overheating	Disconnect device; allow panel to cool; reconnect. If persists, stop use.
Reduced charging speed	Dirty panel, low sun angle, high temperature	Clean panel surface; adjust angle toward sun; provide ventilation if hot.
Physical damage (cracks, tears)	Impact, sharp bend, puncture	Discontinue use. Contact customer service for repair/replacement options.

Reset: Disconnect all devices, roll up panel, wait 1 minute, unroll and reconnect in sun.
