Different from the mainstream single case costing studies in the existing literature, which produces results highly specific to the grid configuration and gives limited reference value for future projects, this paper contributes to the knowledge base by gathering publicly available data.
Summary: Selecting the best bracket material for solar photovoltaic systems impacts durability, cost, and energy efficiency. This guide explores aluminum, steel, and composite options, backed by industry data and real-world examples, to help installers and project developers.
