3. Setup
3.1 Unpacking and Initial Inspection
Carefully remove the solar panel from its packaging. Inspect the panel for any signs of damage during transit. If any damage is found, do not use the product and contact customer support immediately.
3.2 Deployment
To deploy your solar panel for use:
- Unfold the solar panel completely on a flat, stable surface.
- Extend the integrated kickstands located on the rear of the panel.
- Adjust the angle of the kickstands to position the panel directly towards the sun. For optimal performance, aim for a perpendicular angle to the sun's rays.

3.3 Connection
Connect the solar panel to a compatible EcoFlow portable power station or other solar generator using the appropriate solar input cable. Ensure the connectors are fully inserted and secure. Refer to your power station's manual for specific connection instructions.
4. Operating Instructions
4.1 Solar Charging Principles
The solar panel converts sunlight into electrical energy. The bifacial design captures light from both sides, increasing efficiency. The front side captures direct sunlight, while the rear side captures reflected and diffused light from the ground or surrounding surfaces.
4.2 Optimizing Performance
- Angle Adjustment: Regularly adjust the panel's angle throughout the day to follow the sun's path. This ensures the most direct sunlight hits the panel.
- Clear Sky: Operate the panel in clear, sunny conditions for best results. Clouds, shade, and obstructions will significantly reduce power output.
- Clean Surface: Keep the panel's surface clean from dust, dirt, leaves, or snow. A dirty panel will have reduced efficiency.
- Reflective Surfaces: For bifacial panels, placing the panel over a light-colored or reflective surface (e.g., sand, light concrete, snow) can enhance the rear side's contribution to power generation.
5. Maintenance
5.1 Cleaning
To maintain optimal performance, clean the solar panel regularly:
- Use a soft, damp cloth to wipe down the surface of the panel.
- For stubborn dirt, use a mild, non-abrasive cleaning solution.
- Do not use harsh chemicals, abrasive materials, or high-pressure water, as these can damage the panel.
- Ensure the panel is dry before folding or storing.
5.2 Storage
When not in use, store the solar panel properly:
- Fold the panel completely and secure any latches or straps.
- Store the panel in a cool, dry place, away from direct sunlight and extreme temperatures.
- Protect the panel from physical impact and sharp objects.
