4. Setup and Installation
The EF ECOFLOW 100W Rigid Solar Panels are designed for straightforward installation. They feature pre-drilled holes for easy mounting.
4.1 Mounting
- Choose a Location: Select a location that receives maximum direct sunlight throughout the day. Consider surfaces like RV rooftops, marine vessels, or fixed structures.
- Secure Mounting Brackets: Use appropriate mounting brackets (sold separately) such as Z-brackets or adjustable tilt mounting brackets. Align the brackets with the pre-drilled holes on the solar panel frame.
- Fasten Panels: Securely fasten the panels to your chosen surface using suitable hardware. Ensure all connections are tight to prevent movement, especially in windy conditions.
Warning: Ensure the mounting surface is structurally sound to support the weight of the panels and withstand environmental factors. Consult a professional if unsure.

4.2 Electrical Connection
- Identify Connectors: Each solar panel is equipped with standard MC4 connectors.
- Connect to Power System: Connect the solar panels to your EF ECOFLOW Power Kit or other compatible solar charge controller/battery system using appropriate solar cables (sold separately). Ensure correct polarity (+ to + and - to -) to avoid damage.
- Series or Parallel: Depending on your power system's requirements, you may connect multiple panels in series or parallel. Refer to your power system's manual for specific wiring diagrams and voltage/current limits.
5. Operating Instructions
Once installed and connected, your EF ECOFLOW 100W Rigid Solar Panels will begin generating electricity when exposed to sunlight.
- Sunlight Exposure: Position the panels to receive maximum direct sunlight. Any shading, even partial, can significantly reduce power output.
- Monitoring: If connected to an EF ECOFLOW Power Kit or a smart charge controller, monitor the input power and battery charging status via the device's display or app.
- Optimal Angle: For fixed installations, consider the optimal tilt angle for your geographic location to maximize annual energy harvest. Adjustable tilt brackets can help achieve this.

6. Maintenance
Regular maintenance ensures optimal performance and longevity of your solar panels.
- Cleaning: Periodically clean the surface of the solar panels with a soft cloth and mild, non-abrasive cleaner to remove dust, dirt, bird droppings, or other debris. Ensure the panels are cool before cleaning.
- Inspection: Regularly inspect the panels for any physical damage, such as cracks in the glass, loose frames, or damaged cables. Check electrical connections for corrosion or looseness.
- Shading: Ensure no new obstructions (e.g., growing trees, new structures) are casting shadows on the panels.
7. Troubleshooting
If you encounter issues with your solar panels, consider the following common troubleshooting steps:
- No Power Output:
- Check for sufficient sunlight exposure.
- Verify all electrical connections are secure and correctly polarized.
- Inspect cables for damage.
- Ensure the solar charge controller or power station is functioning correctly.
- Low Power Output:
- Clean the panel surface if dirty.
- Check for partial shading from nearby objects.
- Verify the panel's angle is optimized for the current sun position.
- Consider ambient temperature; extreme heat can slightly reduce efficiency.
- Physical Damage: If the panel glass is cracked or the frame is bent, contact customer support. Do not attempt to repair damaged panels yourself.
