In this work, analyzes of existing devices for measuring the current-voltage characteristic were carried out in order to compare several devices. The purpose of this work is to develop a device for measuring the current-voltage characteristics of photovoltaic modules and the environmental factors affecting them. The paper discusses a system for monitoring solar module parameters that measure air temperature, module temperature, solar radiation, wind speed, current-voltage characteristic, maximum power point (MPP), efficiency, and fill factor (FF) and stores the data in a computer. The system is constructed around a programmable microcontroller with an analog-to-digital converter built in. The suggested system's program code also includes an algorithm for determining the maximum power point of the solar module. Because every parameter are taken into account automatically and written to the computer in the form of tables, the system performs all measurements in real time and is simple to use. In order to compare the suggested monitoring system with alternative commercial measuring equipment, the research looked at their properties. The proposal includes a circuit diagram for a monitoring system as well as an electrical circuit to measure current-voltage characteristics.
