A dataset of four years old PV modules under outdoor test conditions in Dhaka Bangladesh

The performance degradation data for 40 external photovoltaic (PV) modules placed on a five-story building in Mirpur, Dhaka, Bangladesh, during a four-year period is shown in this dataset. It comprises electrical characteristics that are measured in accordance with IEC60904-1 standard conditions, such as voltage, current, power, and fill factor. Additionally, the data includes image-based analysis that pinpoints elements such as microcracks, hotspots, and dust deposition. Researchers, legislators, and business experts interested in the long-term upkeep and dependability of photovoltaic systems in tropical regions would find this dataset to be beneficial.
