Our 400W portable solar panel offers high solar output, conversion efficiency,
and a convenient folding design, making it ready to grab and go at any time.
Pair two 400W portable solar panels with your DELTA 3 Plus, which supports up
to 1000W solar input, to ensure you’re fully powered up, no matter where your
adventures take you.

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, giving you even
more energy to recharge your portable power.

Our 400W portable solar panel can keep collecting energy even during a downpour.
With a protective ETFE film and a high IP68 resistance level, the solar cells can
withstand environments from humid and wet to dry and dusty.
