Connector Compatibility

Check connectors like XT60, Anderson, or DC plugs match your gear. Multi-port connectors offer flexibility for different brands. Adapter cables may be needed.

Ensure the panel includes connectors compatible with your specific power station model.

Durability

ETFE coatings resist scratches and UV damage better than standard layers. Sturdy frames handle wind and impacts. Look for certifications for quality.

Look for ETFE coatings and robust frames to extend the service life of your panel.

Warranty and Support

A 3-year warranty is standard while some offer longer. Technical support helps resolve issues quickly. Check brand reputation.

Prefer brands offering a 3-year warranty and accessible technical support for peace of mind.

Efficiency

Efficiency rates from 20% to 25% affect power output per area. Higher efficiency means faster charging. This depends on cell quality.

Opt for panels with 23%+ efficiency for better energy conversion in limited space.

How to Use and Care for Your 350W Solar Panel

To maximize efficiency, position the panel to face the sun directly during peak hours. Adjust the angle using the kickstands to capture more light as the sun moves. Ensure the surface is clean and free of debris to prevent shading and heat buildup.

Store the panel in its included bag when not in use to protect against scratches and environmental damage. Keep connectors dry and covered to prevent corrosion. Avoid placing heavy objects on the panel or stepping on it to avoid cracking cells.

Regularly check for dirt or dust on the surface and wipe gently with a soft cloth. Avoid using harsh chemicals or abrasive tools. Follow safety guidelines and bypass diodes to ensure stable operation during use.
