Abstract

The modules mismatch loss and strings mismatch loss in PV module is theoretically and universally recognized in the PV industry [1]. But for specific projects, how to calculate these losses as well as how to reduce the impact of these losses through external rational wiring was rarely studied. In this paper, the engineering calculation method will be summed up and the relevant formulae suitable for engineering calculation or equipment configuration principles such as cables can finally be obtained by constructing the DC side equivalent circuit model of the photovoltaic power station, and also calculating of modules and strings mismatch loss data based on circuit analysis, which can in turn provide the essential theoretical basis for the accurate efficiency calculation of the photovoltaic power plant system and provide certain theoretical support for engineering drawing optimization design as well.
