Abstract
This paper details an investigation into the appearance of hot-spots in two large grid-connected photovoltaics (PV) plants, which were detected after the visual inspection of trackers whose energy output was decreasing at anomalous rate. Detected hot-spots appeared not only in the solar cells but also in resistive solder bonds (RSB) between cells and contact ribbons. Both types cause similar irreversible damage to the PV modules, but the latter are the main responsible for the detected decrease in energy output, which was confirmed in all experimental testing campaign. The results of this investigation, for example, how hot-spots were detected or their impact oil the output power of PV modules, may be of interest for the routine maintenance of large grid-connected PV plants.
