Mismatch losses minimization in photovoltaic arrays by arranging modules applying a genetic algorithm

Photovoltaic (PV) arrays consist of series and parallel connections of PV modules. Difference in current–voltage (I–V) characteristics among a batch of modules form an array causes power losses in PV systems referred to as mismatch losses. These power losses are conventionally reduced by module sort...
