    About this item

    Product details

    The EcoFlow 400W portable solar panel offers higher wattage and better efficiency than standard solar panels thanks to their monocrystalline cells. Unlike fixed solar panels, portable solar panels can be easily repositioned and adjusted to follow the sun's movement throughout the day.

    Convert sunlight into clean, renewable energy using 400W portable solar panels, perfect for camping, RVs, and home use.

    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.

    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 up to 23%, we use multi busbar monocrystalline cells, so you get even more energy to recharge your portable power.

    EcoFlow's 400W portable 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.

    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 27.5 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.

    Our 400W portable 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.

    Powerful, Well-Built, and Easy to Use

    The EcoFlow 400W Portable Foldable Solar Panel has been outstanding. It delivers strong, consistent power in good sunlight and pairs perfectly with EcoFlow power stations. Setup is quick, the folding design is convenient, and it’s easy to reposition to track the sun. Build quality is excellent—sturdy materials, solid connectors, and it feels made for outdoor use. Despite its size, it’s manageable to transport and stores neatly when folded. This panel has been a reliable way to recharge during outages and off-grid use. If you need serious portable solar power, this panel is worth the investment. Highly recommended.

    Great panel!

    The solar panel works as it's supposed too. Gets close to the wattage, if placed correctly in the sun. Charged my EcoFlow Delta within 3 hours from 50% on a sunny and warm day. I did have an issue with the kickstand and had to prop it up using outdoor furniture, but I'm assuming that was user error. :-) One of the accessory hooks broke, but they replace it very promptly.

    Convenient and charge quickly.

    Solar panels are great and provide faster charging than I thought they would. They are extremely heavy however and I was unable to move them around well. Also, they are floppy and it is difficult to easily reposition them for sunlight. If you are not very strong and small in stature, you should consider a smaller panel set.
