AB Photovoltaic (PV) modules are the core of every PV system, representing the power generationand their operation will affect the overall plant performance. It is one of the elements within aPV site with the higher failure appearance, being essential their proper operation to producereliable, efficient and safety energy. Quantitative analysis and characterization ofmanufacturing, soldering and breaking PV defects is performed by a combination ofelectroluminescence (EL), infrared thermography (IRT), electrical current voltage (I-V) curvesand visual inspection. Equivalent-circuit model characterization and microscope inspection arealso performed as additional techniques when they contribute to the defects characterization.A 60-cells polycrystalline module has been ad hoc manufactured for this research, with differentdefective and non-defective cells. All cells are accessible from the backside of the module andthe module includes similar kinds of defects in the same bypass string. This paper characterizesdifferent defects of PV modules to control, mitigate or eliminate their influence and being ableto do a quality assessment of a whole PV module, relating the individual cells performance withthe combination of defective and non-defective cells within the module strings, with theobjective of determining their interaction and mismatch effects, apart from their discreteperformance.
