This dataset primarily describes the support structures and civil works required for open-ground photovoltaic electricity generation systems, including photovoltaic panel mounting structures, foundations for mounts, foundations for inverters and transformers, cable laying, and land occupation. For the demolition, recovery, and disposal phases of related materials, it is assumed that the recycling rate for metals, reinforcing steel, and similar materials is 90%, with the remaining materials being disposed of via landfill.
