Photovoltaic Module Metal Frame segmentation by type isolates three material families—aluminum, steel, and composite frames—each delivering distinct performance attributes that affect market sizing. Aluminum frames, comprising roughly 55 % of the market, dominate due to their high strength‑to‑weight ratio, corrosion resistance, and compatibility with automated extrusion processes, making them the default choice for residential and many commercial modules. Steel frames, representing about 30 % of shipments, are favored in utility‑scale and high‑wind environments where superior tensile strength and rigidity are required, albeit at the cost of increased weight and the need for protective coatings. Composite frames, currently around 15 % of the market, blend polymer matrices with reinforcing fibers to achieve lightweight structures with enhanced thermal expansion control, appealing to niche applications such as bifacial modules and floating PV farms. The relative share of each type directly influences raw‑material procurement, manufacturing equipment investment, and overall market revenue. Lifecycle cost analysis indicates aluminum’s lower upfront price, steel’s superior durability, and composites’ higher upfront cost offset by weight‑related efficiency gains, influencing OEM frame selection in long‑term project economics.
