Can imaging technologies be used to analyze faults in photovoltaic (PV) modules?

This paper presents a review of imaging technologies and methods for analysis and characterization of faults in photovoltaic (PV) modules. The paper provides a brief overview of PV system (PVS) reliability studies and monitoring approaches where fault related PVS power loss is evaluated.

Can a thermographic inspection improve PV maintenance decisions?

Starting from well-known mathematical models of PVMs, Pinceti et al. propose an innovative approach to correlate the results of a thermographic inspection with the power losses and the consequent income reduction, as a valid tool for supporting decisions about the maintenance actions on PV plants .

Can aerial scanning improve power production in large-scale PV plants?

The development of imaging techniques will continue to be an attractive domain of research that can be combined with aerial scanning for a cost-effective remote inspection that enable reliable power production in large-scale PV plants. 1. Introduction

What is the expected electrical mismatch loss of production run PVMs?

The expected electrical mismatch loss of production run PVMs in arrays of various sizes, whether connected as series, blocks or parallel strings, is typically less than 1 % of the nominal power , , , .

What are PVM IRT image patterns observed in outdoor measurements?

Summary of PVM IRT image patterns observed in outdoor measurements, their description and possible fault modes. Single cells are warmer, lower parts and close to frame hotter than upper and middle parts. The table is modified from .

How effective is IRT imaging for characterization of PVMs?

IRT imaging has been identified and widely researched as comprising an effective and powerful tool for qualitative characterization of PVMs, enabling detection of faults that could not be discovered visually.
