The objective of this study is to analyze the influence of various parameters on the expected lifespan of transformers, assess the economic viability for utilities and end-users to implement photovoltaic generation systems, and measure the extension of transformer lifetime. For power distribution transformers, understanding the working temperature and humidity is crucial. Abnormal values of these parameters result in electrical and mechanical stress, ultimately affecting the transformer’s lifespan. As an alternative, distributed solar generation systems with storage in batteries were explored. Different scenarios involving solar panels and inverters were analyzed to determine the optimal solution for load relief, reduction in operating temperature, and improvement in the utilization factor, consequently enhancing the overall lifespan.
