Thermography Diagnostics of Photovoltaic Panels

Abstract:

The technologies based on photovoltaic effect, which achieve their fulfilment from small applications to some big power stations that can be in size of few square kilometers, still come to the fore more. The growth of the interest and installations of these technologies brought also amount of technical, legislative or financial problems and also in issues of safety of its operation, of its service, of intervention of rescue squad and last but not least of recycling. Solar thermography is the use of an infrared camera to inspect photovoltaic solar systems for problems that can cause; damage to the cells, loss of efficiency, and fire hazards. In this work were observed temperature distributions for solar panel using digitized thermal imagers and the detected problems with the overheated connections at the junction box from the front of the panel and problems with a defective cell. Also were detected problems of photovoltaic panel with the overheated place caused by dirt on the panel.
