A review and summary of cell and module mismatch losses from theoretical and experimental studiesStudies on power loss due to photovoltaic (PV) cell and module parameter mismatch were reviewed. The losses result from the current voltage (I-V) characteristics of cells which vary over a manufactured lot. The peak power and the peak power I-V point vary from cell to cell. The largest parameter variation occurs in the cell photocurrent generation and the most significant loss occurs in series connections since all cells are essentially limited by the lowest photocurrent. Most theoretical studies address only photocurrent variation effects, which consider shunt and series resistance, ideality factor and saturation current to be comparatively insignificant. One study is identified which specifically configured the study of mismatch loss effects. Experimental results consist of estimates based on limited data not taken from specially configured tests.
