Abstract
The recent laboratory tests are showing progresses in both materials and production technology of Photo-Voltaic (PV) modules, nevertheless their efficiency yet results relatively low. Moreover, efficiency is also a very critical issue for already installed PV modules, because they were produced employing a less performing technology. In this scenario, a diagnostic approach able to check the current state of health of each single PV cell assumes a strategic importance. This paper introduces a thermography-based diagnostics able to provide a detailed, clear and unambiguous information, thanks to a computer aided investigation based on the InfraRed (IR) analysis: the proposed method, in fact, provides a fine diagnostics (both in numerical and in qualitative form) for each cell of the PV module. In addition, the paper proposes a software platform that implements the workflow and automatically generates a report, so resulting a fast and effective tool for the professionals of the Operation and Management (O&M).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
