Uni-Solar PVL-128 128W Flexible Amorphous Solar Panels 24V Metal Roofing Qty 30

This is a carton of 30 Uni-Solar PVL-128 128-watt flexible amorphous silicon solar panels. The PVL-128 is a peel-and-stick, thin-film photovoltaic panel designed to bond directly to metal and membrane roofing surfaces without roof penetrations or mounting hardware. At 18 feet long and just over an inch wide in the flat profile, the panels ship coiled on a roll inside a single carton, ready to unroll and adhere.

Applications

The Uni-Solar PVL series is a line of building-integrated photovoltaic (BIPV) panels developed by United Solar Ovonic, a Michigan-based thin-film solar manufacturer. The PVL-128 was designed specifically for low-slope commercial and industrial roofing, where traditional glass-framed crystalline silicon panels cannot be used due to added structural load or the risk of roof penetrations voiding waterproofing warranties. The adhesive backing bonds the panel directly to standing-seam metal roofs or single-ply membrane systems, making it a common choice for retrofit solar on warehouses, distribution centers, and large commercial buildings. Amorphous silicon thin-film technology performs better than crystalline silicon in diffuse and low-angle light conditions, which gives these panels a production advantage on overcast days and in early morning or late afternoon hours. The PVL-128 is still used in commercial BIPV installations, off-grid applications, and custom solar projects where flexibility and light weight are priorities. Installers and integrators working with legacy Uni-Solar systems also source these panels for replacements and expansions.
