When not in use, fold the solar panel and store it in a dry, cool place away from direct sunlight and extreme temperatures. The magnetic handle and compact design facilitate easy storage and transport.
Troubleshooting
- No Power Output:
- Ensure the solar panel is exposed to direct sunlight.
- Check all cable connections for secure fit.
- Verify that the connected power station or device is compatible and functioning correctly.
- Low Power Output:
- Adjust the panel's angle using the kickstands to optimize sun exposure.
- Clean the panel surface to remove any dirt or obstructions.
- Ensure no shadows are cast on the panel.
- Overheating:
- While the panel is designed for outdoor use, avoid prolonged exposure to extreme heat without proper ventilation.
