What parameters are measured in photovoltaic monitoring systems?

Besides the above parameters, additional parameters are measured in photovoltaic monitoring systems to diagnose faults in any component (modules, connection lines, converters, inverters, etc.) or better understand the system's performance.

What is a solar photovoltaic (PV) system?

A solar photovoltaic (PV) system includes the main components of PV modules, a solar inverter, and a bias of system (BoS), which can generate AC and DC power. However, the desired efficiency of PV systems relies on many factors as well as understanding the component functionality and configuration.

How do you measure the electrical characteristics of PV modules?

Measurement of monitoring systems parameters The electrical characteristics of the PV modules are stated by current–voltage (I-V) and power–voltage (P-V) curves (Kharb et al., 2014, Boutana et al., 2017, Aranda et al., 2009). It is important to measure current and voltage values to monitor the power generation of the PV module.

How does a PV module monitoring system work?

The proposed monitoring system detects energy losses over 5% in the PV module through a comparison between the predicted and measured energies. Moreover, in ref. , the specifications of a PV module were simulated under various weather conditions to track the performance degradation of the PV module.

What is a photovoltaic monitoring system?

Local and remote photovoltaic monitoring systems are primarily used to collect data about solar panels for the purpose of maintenance and repair. Additionally, monitoring systems are used to measure and analyze energy production performance data. Another objective is to minimize hazards to personal safety associated with periodic manual controls.

Can a PV module monitoring system detect a defective PV module?

PV module monitoring systems that measure the total data of the inverter or PV array are insufficient for detecting a defective PV module. To improve the efficiency of PV systems, cost-effective, compact systems that can provide data acquisition and monitoring data at the PV module level are required.
