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.

Why do we need a solar PV Monitoring System?

Due to various environmental factors such as soiling, temperature, irradiance etc., the operation and functionality of solar PV systems can be affected. Thus, the accuracy and performance of the solar PV system can be improved by employing an efficient solar PV monitoring system .

How a solar PV power plant is monitored?

The monitoring of the solar PV power plant is performed either at the module, string, or system level. The monitoring of the solar PV at the system level provides information about the system exclusively. The monitoring technology related to panels and strings helps in identifying the root cause of the problem precisely.

Are solar PV Monitoring systems based on data processing modules?

Firstly, the review of solar PV monitoring systems based on data processing modules with its design features, implementation, comments or suggestions, and limitations is presented. Secondly, various data transmission protocols are studied for solar PV monitoring systems.

What are the different types of PV Monitoring Systems?

The PV monitoring systems can be broadly classified as ground based or space based monitoring systems. The former approach is more prevalent due to its quick response and accuracy in monitoring the PV system health.

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.
