The installation costs of SPP plants are quite high. This situation increases the amortization period of investments. Lowering these costs during the installation phase will pave the way for more investments. One of the most important cost items of Solar Power Plants (SPP) is steel construction costs. In this study, it is aimed to reduce the cost by designing the best performance product by reducing the weight of C profiles, one of the steel constructions used during the installation of solar panels, with shape and topology methods. The results obtained show that shape and topological optimization can provide significant gains in terms of cost.eninfo:eu-repo/semantics/openAccessWeight ReductionSolar Energy SystemsStructural and Topology OptimizationSteel Construction ProfilesManufacturing EngineeringArticle10.26701/ems.1388159742852951214542
