What is photovoltaic system monitoring?

This chapter provides the rationale behind photovoltaic (PV) system monitoring, its purpose, the necessity of proper measuring, and the frequency required to produce meaningful results. The need for system monitoring comprises three groups: user feedback, performance verification, and system evaluation.

What is the difference between panel level and system level monitoring?

Monitoring at system level gives information about how the PV system is working as a complete unit. On the other hand, monitoring at panel level provides information on each panel performance. Panel level monitoring enables to identify problems related to PV system more accurately. This attribute improves the economic factor of PV system.

What is PV system monitoring?

PV system monitoring also makes it possible to compare power output from PV system with billing information. Even if the PV monitoring system is not checked regularly, it will send an alert whenever there is a predefined event that requires owner's concern. Monitoring for PV can be utilized at two levels which are, panel level and system level.

Are PV Monitoring systems suitable for large scale PV plants?

The cost and complexity of existing PV monitoring systems restricts their use to large scale PV plants. Over the past decade, different aspects of PV monitoring systems were reported in wide range of literature. In this paper, a comprehensive review of various PV monitoring systems is presented for the first time.
