The objective of the solar PV monitoring system is to analyze all the possible data, which affects the performance of solar PV system in real time and to give the correct information about the that occurred in the solar PV system.
The PV current and voltage are obtained through the current and voltage sensors. The output of the two sensors is then transmitted to the microcontroller of the Arduino UNO board. During the acquisition process, the data obtained are stored and plotted in real-time in the Excel spreadsheet. This project is linked to this research paper .
The faults in the PV panel, PV string and MPPT controller can be effectively identified using this method. The detection of fault is done by comparing the ideal and measured parameters. Any difference in measured and ideal values indicate the presence of a fault.
This sensor is usually used in grounded PV systems and requires the additional measurement of the surface magnetic field which may be generated by the electric current generated by each solar panel. Such measurement can detect both the cluster failure and panel failure.
Despite the above listed challenges, I-V and P-V curve measurement is the actual industry standard technique for inspecting and evaluating the performance of a solar plant. Another alternative is to deploy current and voltage sensors for online monitoring of the PV plant which are typically deployed inside the inverters.
Fault detection is an essential part of PV panel maintenance as it enhances the performance of the overall system as the detected faults can be corrected before major damages occur which a significant effect on the power has generated.
