The EcoFlow 400W Lightweight Bifacial Foldable Solar Panel updates the classic 400 W folding module with a bifacial cell design that captures both direct sunlight on the front and reflected light on the back. It weighs 10.2 kg - nearly half of the previous generation - and folds to 65.9 x 96.7 x 3.6 cm, opening to 250.9 x 96.7 x 2.6 cm. N-Type TOPCon monocrystalline cells with a 25% efficiency rating and IP68 weatherproofing make it a serious tool for portable power stations. Note that the panel uses a permanently attached XT60 cable (3.5 m) instead of MC4 connectors and cannot be wired in series.

• 400 W max output (±5 W) with 25% panel efficiency across bifacial cells.
• Bifacial layout captures reflected light from the ground, roof or wall behind the panel.
• Integrated XT60 cable of 3.5 m plugs straight into an EcoFlow power station.
• Adjustable kickstand supports 30°, 45° and 60° positions; Solar Angle Guide helps hit 90° to the sun.
• Built-in handle keeps the 10.2 kg package easy to carry to the deployment site.
• IP68 water and dust protection covers rain, sand and outdoor storage.
