Photovoltaic solar energy has been highlighted every day as one of the main sources of renewable energy. Its main advantage is associated with the isonomic availability of the fundamental resource for the production of electricity through photovoltaic modules, sunlight. In this context, knowing and understanding the various phenomena associated with this conversion is a fundamental step for the development of this technology. Therefore, this work was based on the study of the effect of mechanical stress on a monofacial photovoltaic module with monocrystalline silicon cells. Initially, the module was characterized through several tests that included: maximum peak power, electrical isolation, electroluminescence. Then, the equipment was subjected to static mechanical load testing according to MQT 16 of IEC 61215:2016 and later characterized again with the same initial tests. During the mechanical test there was no evidence of circuit opening – indicating the quality of the interconnections between cells and buses. Furthermore, the results showed that the M7K photovoltaic module, after mechanical stress, showed a reduction in maximum power (3.6%) - a result of the appearance of longitudinal and transversal cracks, as well as the breakage of six cells. Another significant impact refers to the increase in series resistance and also in shunt resistance.
