A cost-benefit analysis for reconfigurable PV modules under shading

摘要: Abstract Non-uniform conditions within a PV module lead to significant energy losses in conventional topologies. Some of the lost due partial shading can be recovered by installing reconfigurable modules. In order explore potential benefits topologies installations where non-uniform are dominant, three scenarios simulated throughout year, both for and This allows evaluation performance each topology estimation long-term gains. Using cost function, which includes additional investment cost, gain translated financial terms. Through this, locations beneficial, terms, identified. The methodology is applied case modules with snake-like configuration. Simulation results show that these allow higher production compared under all scenarios. However, they remain economically profitable over 20 years only expected occur daily, either full year or at least period generation high.
