Near-Static Shading Exploration for Smart Photovoltaic Module Topologies Based on Snake-like Configurations

摘要: Variable shading due to clouds and nearby objects has a severe impact on the energy yield of photovoltaic installations. Due industry's standard permanently series-connected cells in (PV) module, partial creates mismatches between Current-Voltage (I-V) characteristics cells. This article proposes an alternative configurable intramodule cell interconnection topology whereby connections can be adapted during operation allow optimized power production. The proposed outperforms significantly conventional 10 × 6 module under heavy shade. Moreover, this is achieved quite flexible way with negligible overhead uniform irradiation conditions.
