Stay off the grid with EcoFlow 400W Solar Panel. Made up of the efficient mono crystalline silicon cells, it can recharge DELTA and your electric devices, and keep your equipment running without interruption when connected to our portable power station.

400W Portable Solar Panels
Our 400W portable solar panel offers high solar output, conversion efficiency rating, and a convenient folding design so it’s ready to grab and go at any time.



Ready for the outdoors.
Made from durable and flexible materials, the portable solar panel is perfect for off-grid living and travel. Its multi-layered design offers high impact resistance for the rugged outdoors, while its 16 kg light-weight means effortless carrying to a campsite. A rigid layer embedded in the carry case protects the panel from overbending when you carry or store it.

Built to weather the storm.
Our 400W solar panel can carry on collecting energy even during a downpour. With a protective ETFE film and a high IP resistance level of 68, the solar cells can withstand environments from humid and wet to dry and dusty.

Take solar power on the go.
EcoFlow’s 400W solar panel is a camping or RV must-have. The compact design saves valuable space for your other travel essentials. When you’re ready to head off on your next adventure, simply collapse the panel down to store in your van or car.
