The research aimed to enhance solar dryer technology by integrating Phase Change Materials (PCMs) and photovoltaic (PV) panels to provide consistent drying conditions. A novel solar dryer was designed with PCM tubes placed horizontally behind a copper plate to store thermal energy, ensuring continuous drying at off-sunny hours. The research investigated the process of drying potato slices in different weather conditions to assess the enhanced dryer’s performance. Key findings from our extensive testing show that the PCM-integrated solar dryer significantly improves drying efficiency. Specifically, we observed a 30% reduction in drying time, a 25% increase in moisture removal rates, and a 20% increase in overall drying efficiency compared to traditional solar dryers. These improvements highlight the effectiveness of integrating phase change materials in enhancing the performance of solar drying systems. This study provides valuable insights into the development of more efficient and sustainable solar dryers for agricultural products. This technology aims to minimize losses after harvesting, enhance the products quality as well as offer economic advantages to farmers. The research demonstrates the potential of PCM-integrated solar dryers as a sustainable and efficient solution for agricultural drying, with future studies needed to explore its application across different crops and regions.}, number={2}, publisher={Uluslararası Uygulamalı Termodinamik Derneği İktisadi İşletmesi}
