Study of defects in PV generators using image analysis techniques with Matlab

Abstract

It is evidence that the useful life of the photovoltaic generator, as its correct operation, define the production and the profitability of a photovoltaic installation. There are several aspects that cause descents in the level of production of the generator and therefore losses in the installation. Based on it, it has developed numerous of both corrective and preventive maintenance that avoid these circumstances. Along the document there are revised the possible defects that the photovoltaic generator can have and the techniques of detection of the same ones. Inside the techniques of analysis and examination [1] we will center on the very concrete one: the visual inspection and its development by image analysis tools with Matlab. The techniques used are part of the tool “Image processing toolbox” that provides a finished set of algorithms of standard reference and graphic hardware to the prosecution, the analysis and the visualization of images and the development of complementary algorithms. Across the employment and the adaptation of some of the included algorithms it will be claimed to approach a step more specializing in the conventional visual analysis used in the maintenance of the plants of photovoltaic solar energy.
