1. Mismatch is the loss of power in series-connected photovoltaic modules. This is due to the different performance characteristics of the individual solar modules. If several modules are connected in series, the same current flows through all of them. The low-power PV module in a series circuit limits the current of all connected photovoltaic modules.
2. Mismatch is a term used in English, which is found mainly in PV systems whose modules are connected in series. The mismatch is characterized by a loss of performance, which can be caused by the following factors: differences in the performance of the PV modules, differences in the inclination of the PV modules, differences in the orientation of the PV modules or differences in the PV modules used.
