Photovoltaic (PV) modules have been in operation in the field for more than 20 years, and policies and technologies for the recycling of PV modules for resource reuse have been developed and implemented. Even PV modules that have been in operation for more than 20 years retain more than 80% of their initial performance. If there are no failures that affect output mismatch, such as hot spots or cell cracks, they can be reused. In this study, a 50 kWp reused PV system was built using PV modules collected from PV systems that had been in operation for more than 10 years, and the performance of the PV system after operation for 1 year was analyzed. In addition, the PV system was built with the same capacity as new PV modules to compare it with the new modules, and a comparative analysis was performed. IR, EL, and monitoring data analysis were also performed. If the performance of the PV system using reused PV modules can be secured, growth is expected not only in the repowering field but also in the construction of new power plants using reused PV modules.
