Description

The EF EcoFlow 400W lightweight portable solar panel combines bifacial design with N-Type solar technology to deliver up to 445W output under BNPI test conditions. The dual-panel system captures energy from both the front primary panel and rear-side panel that harnesses ambient light, generating significantly more electricity from the same sunlight compared to traditional monofacial panels. With industry-leading 25% conversion efficiency, this portable solar solution recharges your power station faster whilst remaining constructed with advanced lightweight materials for easy transport and deployment. Ideal for off-grid living, camping, outdoor events, or backup power systems, the EcoFlow 400W combines high-energy capture with practical portability to maximise solar charging performance wherever you need it.

Key Features

The EF EcoFlow 400W delivers up to 445W output under BNPI test conditions thanks to its bifacial design with primary and rear-side panels.

N-Type solar technology enables a high conversion efficiency of 25%, allowing faster recharging of compatible power stations.

Bifacial design captures ambient light on the rear-side panel, generating more electricity than traditional monofacial solar panels from equivalent sunlight.

Advanced lightweight materials make the EcoFlow 400W portable solar panel easy to transport and suitable for camping, off-grid, and outdoor applications.

Dual-panel energy capture system maximises solar output efficiency in diverse lighting conditions and installation angles.
