Abstract:

With increasing use of photovoltaic (PV) modules, their reliability is a matter of keen interest for the research community as well as the manufacturers. Different techniques have been utilized for the reliability analysis of the PV module such as the use of IV/PV curve tests, electroluminescence (EL), photoluminescence (PL), and infra-red (IR) imaging. Amongst them, EL imaging, which can effectively determine defective regions (inactive areas) in the modules, is a commonly used tool on the commercial level. This paper presents the development of a low-cost EL imaging setup for PV modules. A commercially available DSLR camera was modified into a specialized EL camera by using an IR filter. EL imaging was performed in a dark environment to avoid stray light from entering the testing area. The pre and post-processing of the images obtained by means of the setup were performed using MATLAB software. The development of the setup followed the use of standard operating conditions and international standard IEC 60904-13. The images obtained by the indigenously built setup were compared with those obtained by commercially available EL setup. The available EL setups in Pakistan are imported from abroad at high cost while this setup was developed using commercially available inexpensive components to make it economical, Furthermore, image analysis technique was applied on the EL images obtained through this setup. Cracks were detected manually as well as through image analysis in MATLAB.
