Computer simulation of the effects of electrical mismatches in photovoltaic cell interconnection circuits

A Pascal program, PVNet, has been developed at the Commission of the European Communities Joint Research Centre, Ispra, to model the electrical behaviour of solar cell interconnection circuits. The program calculates three-quadrant solar cell current-voltage (I–V) curves using a lumped parameter equivalent circuit model, combines them to obtain the resultant I–V curve of any interconnection circuit, and calculates the operating point of each...
