Xunlight XRD12-100 100W 20V Flexible Amorphous Solar Panel Off-Grid Solarlok

Xunlight XRD12-100 100W 20V Flexible Amorphous Solar Panel Off-Grid Solarlok

The Xunlight XRD12-100 is a 100-watt flexible amorphous silicon solar panel built on a stainless steel substrate and encapsulated in ETFE and EVA for long-term outdoor durability. At 70 × 35 inches, it rolls down to approximately 12 inches in diameter for compact storage and transport, making it well suited to mobile, marine, and off-grid installations where rigid panels won't fit. These panels were manufactured at Xunlight's Toledo, Ohio facility between 2012 and 2015 and are intended for battery charging and off-grid applications — not for grid-tie use.

Applications

Flexible amorphous silicon panels like the Xunlight XRD12-100 are used in off-grid battery charging systems where weight, flexibility, or curved mounting surfaces make rigid crystalline panels impractical. Typical applications include RV and van builds, marine/boat deck installations, portable power systems, and remote off-grid cabins. Because amorphous silicon captures a broader spectrum of light than monocrystalline or polycrystalline cells, these panels can produce usable power in diffuse or overcast conditions. Xunlight's stainless steel substrate construction made their panels unusually robust for a thin-film product — the cells resist cracking under flex that would destroy glass-laminate panels. Xunlight operated in Toledo, Ohio and closed around 2015; no equivalent replacement panel has been manufactured using the same process, making remaining stock genuinely scarce for buyers who need this form factor. These panels are for off-grid and battery charging use only and are not rated or intended for grid-tie inverter systems.
