High Solar Output

A single solar panel with a unique folding design, our 400W solar panel combines powerful energy production with portability. To achieve a higher solar conversion efficiency of 23%, we use multi busbar monocrystalline cells, so you get even more energy to recharge your portable power station.

Optimize your energy. 

An Integrated, Self-supporting Stand

EcoFlow’s 400W solar panel comes complete with a protective case that doubles as a sturdy supporting stand. Simply set up your panel anywhere and conveniently adjust its angle to get the most sun possible.

Balancing Portability With Protection

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 35.3 lb 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.

IP68 Waterproof Rating

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. 

Water and dust resistance were tested under controlled laboratory conditions with a rating of IP68 under IEC standard 60529 (maximum water depth of 1 meter for up to 72 hours.)

 Frequently Asked Questions

Are portable solar panels effective?

Portable solar panels are an extremely effective, clean, and renewable way to charge a portable power station. EcoFlow 400W portable solar panels have a larger wattage than typical solar panels and are more efficient due to their monocrystalline cells. String up to three 400W portable solar panels and use with a DELTA Pro portable power station for an input of 1200W. Additionally, EcoFlow portable power stations use an MPPT algorithm to ensure a constant energy supply. Unlike static solar panels, portable solar panels are easily moved and adjusted depending on where the sun is in the sky.

Where do you place portable solar panels?

Positioning portable solar panels at an angle between 30-45 degrees, facing the sun's direction, is best. EcoFlow portable solar panels have a built-in stand that can be adjusted depending on the time of day.

Which solar panels are best for camping?

Solar panels that are portable, foldable, and lightweight are the best kind for camping. Pair with a portable power station for immediate power that is clean, green, and renewable.
