PV inverter current mismatch

Array Mismatch Losses

Strings in different orientations, connected to a same inverter, have different current, but similar voltages (except perhaps for temperature). The calculation (option Mixed orientation) shows that the resulting

Photovoltaics and electricity

PV cells are electrically connected in a packaged, weather-tight PV panel (sometimes called a module). PV panels vary in size and in the amount of electricity they can produce.

Current Flow Analysis of PV Arrays under Voltage Mismatch
