Xunlight XLS11-45 45W 12V Flexible Amorphous Solar Panel Battery Charging 155cm

The Xunlight XLS11-45 is a 45-watt, 12-volt flexible amorphous thin-film solar panel designed for portable and permanent battery charging applications. Unlike rigid crystalline panels, this panel uses an amorphous silicon (a-Si) thin-film construction laminated onto a flexible substrate, allowing it to roll up compactly for transport and storage. It measures approximately 61 × 24 inches (155 × 61 cm) when unrolled and rolls down to roughly 12 inches in diameter — making it far more packable than a conventional glass-faced panel of similar output.

Applications

Amorphous thin-film solar panels like the Xunlight XLS11-45 are used wherever a rigid panel is impractical — on curved surfaces, boat decks, RV roofs, tents, vehicle canopies, and portable off-grid setups. Amorphous silicon technology performs relatively well in low-light and diffuse conditions compared to monocrystalline panels, which makes it a practical choice for marine and overcast-climate deployments. The roll-up form factor is particularly suited to applications where the panel must be stowed when not in use. At 45W/12V, this panel is sized for trickle or maintenance charging of 12V lead-acid, AGM, or lithium batteries, or for use with a charge controller as part of a small off-grid system. Xunlight Corporation, based in Toledo, Ohio, was a manufacturer of roll-to-roll deposited amorphous silicon thin-film panels, and the XLS11 series was among their lightweight portable product lines.
