Measuring the electrical parameters of a photovoltaic module by means of a microprocessor measurement system

The paper presents an example of using a microcontroller and a bridge to automatically measure the electrical parameters of a monitored photovoltaic module. Special attention is paid to the analysis of the errors occurring during the conversion of analogue signals as a result of the quantisation of an analogue-to-digital converter. Measurement and calculations were carried out by means of a bridge, one that made it possible to minimise the share of the a/d conversion error in the pooled error while current was measured.
