Galvanized carbon steel photovoltaic (PV) mounts are used for positioning, installing, and securing solar panels in photovoltaic electricity generation systems. Each kg of galvanized carbon steel mount corresponds to 20 Wp of power capacity. This dataset includes key primary and auxiliary materials, energy inputs, atmospheric emissions, and waste from the production process. Infrastructure such as manufacturing equipment and facility construction is not included within the system boundary of this dataset. The end-of-life recycling phase of the photovoltaic mounting systems is included, assuming a 100% steel mass recycling rate; however, energy and material consumption during the disassembly and recycling stages are not included. The life cycle inventory is compiled from data from multiple sources. The production process of the photovoltaic mounting systems includes cutting and blanking, among other steps. Punching, assembly, welding, inspection, and other processes.
