Streszczenie:
The choice of measuring instruments for the experimental
determination of the dark VAR of the PV module as a function of the dark currents from
the applied voltage, taking into account the range of their change under real
operating conditions, is substantiated. A measuring circuit and a working model of the
bench extension with switching devices for rapid change of polarity of the applied
voltage, and measuring devices for the direction and range of current
values of dark currents are developed
