Abstract

A data logger is an electronic device that senses temperature, relative humidity, and other characteristics such as voltage and pulse by combining analog and digital measurements with programming methods. Thus, data acquisition systems (DAQSs) are frequently used in PV facilities to capture all system data to analyze and optimize plant performance. The major purpose of the project is to create a low-cost DAQS. The suggested monitoring system has been used to continuously gather and display the electrical output characteristics of a stand-alone PV system. PV produced voltage, current, and power are examples of such parameters. Furthermore, because the PV module short circuit current is directly proportional to the molar concentration, the global solar radiation may be determined by monitoring it. The proposed system is considered a good solution for collecting the system database to be ready for the analysis and optimization of the PV plant’s performance. The configurations of software and hardware of the proposed system are presented, and the proposed system's performance is tested when integrated with a small size PV system.
