Designing a data logger for an Arduino-based PV analyzer. The goal is to analyze the energy yield of PV. The sensors used are current and voltage sensors integrated into the data logger board to measure parameters that affect the efficiency value of the PV array. Analyzers help measure and record output parameters of PV systems such as current, voltage, and power. The device also can store parameter data such as Temperature affecting PV performance. The advantage of using data loggers is that data can be collected automatically over some time. Additionally, the data can be displayed in the form of V-I and P-V diagrams for analytical purposes. This sequential design can be used for PV systems that provide many components with a specific power. Test-bench results were recorded at a maximum output of 20,016W. This type of data logger can be used as a portable recorder for measuring PV performance in different areas.
