UniSolar PVL-136 136W 24V Flexible Amorphous Solar Panel MC3 Peel Stick NOS

UniSolar PVL-136 136W 24V Flexible Amorphous Solar Panel MC3 Peel Stick NOS

The UniSolar PVL-136 is a 136-watt, 24-volt flexible amorphous thin-film solar panel built on United Solar Ovonic's PowerBond laminate substrate. It features a peel-and-stick adhesive backing that bonds directly to flat or metal surfaces — no mounting hardware, brackets, or penetrations required. The panel is lightweight and rollable, making it well suited for low-profile roof applications and portable setups. These units are new old stock (NOS), pulled from a sealed carton of 30 panels and stored in a temperature-controlled warehouse since manufacture. The PVL-136 has been discontinued; no longer in production, remaining inventory is increasingly scarce.

Applications

The PVL-136 was designed primarily for commercial flat roofs and standing-seam metal roofs, where its adhesive laminate backing bonds directly to the roofing surface without penetrations or racking systems. Because it is flexible and rollable, it is also widely used on RVs, boats, truck rooftops, and trailer roofs where a rigid panel would be impractical. The panel's 24V nominal output makes it compatible with standard 24V battery banks and charge controllers common in off-grid, marine, and mobile applications. Amorphous silicon technology gives it better low-light and high-temperature performance compared to crystalline panels, which makes it well suited for regions with diffuse sunlight or hot climates. The PVL-136 is part of UniSolar's broader PVL series, which was manufactured by United Solar Ovonic in Auburn Hills, Michigan — one of the few thin-film solar lines produced domestically in the United States. The line was discontinued in the early 2010s, and NOS panels like these are the last available supply for installers maintaining existing PVL-based systems or building new installations that require the adhesive-laminate form factor.
