The ZOUPW 480W is a folding bifacial portable solar panel built for off-grid charging of power stations and battery banks. Its composite surface is pitched as more durable than common ETFE and laminated panels, and the bifacial cells collect light on both faces, which ZOUPW says can add up to 30% output, roughly 144W, from rear-side reflection. That puts it among the higher-output folding panels, but the extra wattage depends on what sits behind it, so a reflective or light-colored ground matters. Owners rate it highly for output and build; expect it to be heavy and to need a stand or prop to angle it well.

Owners rate the ZOUPW 480W highly, praising its output and sturdy composite build. Most criticism centers on weight and the setup needed to get the most from the bifacial rear side.
The ZOUPW 480W is a portable, foldable bifacial solar panel. It collects sunlight on both sides, which can increase total energy generation by up to 30%. Under optimal conditions, light reflected onto the rear side can add up to 144W of output.
The panel surface is a composite material. It uses custom N-Type cells made with a non-destructive cutting process, which avoids micro-cracks caused by mechanical stress. Built-in auto bypass diodes activate under partial shading to maintain output, reduce energy loss and prevent hotspot damage.
The panel weighs 22.5 lbs, a power-to-weight ratio of 21.3 W/lb. It folds for transport and can be used for RV, camping and home backup.
