Investigation of Power losses on Solar Photovoltaic Array Interconnections Under Mismatch Conditions [PDF]
Technology and Economics of Smart Grids and Sustainable Energy, 2021 The mismatch effect creates a difference between the sum of maximum power generated by individual Photovoltaic (PV) modules and the overall PV array power output. Mismatch effects can be classified into internal and external mismatch effects. Internal mismatch effect occurs because of factors such as manufacturing defects and ageing.
