Thermographic Analysis of Photovoltaic Panels

Abstract

The paper proposes processing and

interpretation of the thermo-graphical images acquired on

a grid-connected photovoltaic plant (20 kWp). Infrared

analysis allows a reliable evaluation of the state of health

of the plant and at the same time the detection of the

actions needed of the maintenance. In particular the

identification of possible differences between the strings

and the rapid location of local hot spots, breakdowns or

other problems are presented.
