| Freshwater scarcity affects over 40% of the global population, demanding sustainable solutions. Solar stills (SS) present an eco-friendly desalination method, utilizing solar energy for freshwater production. This comprehensive review critically examines design enhancements and operational strategies to optimize SS performance. Notable advancements include the integration of phase change materials (PCMs), nanofluids, and photovoltaic (PV) panels, alongside innovations in fin designs, wick materials, and reflectors. Key findings reveal that incorporating PCMs like paraffin wax can enhance productivity by up to 87.4%, while CuO nanofluids and rotating wick systems achieve a remarkable 350% improvement in freshwater yield. Moreover, PV-integrated SS systems amplify water and electricity generation, with efficiency gains up to sixfold compared to conventional designs. Novel configurations, such as pin-finned absorbers paired with condensers, demonstrate a 76.5% boost in output, while optimal water depths (0.5 cm) yield 4.5 L/m² daily. The study highlights the dual benefits of integrating renewable technologies, balancing sustainability and scalability. It also addresses challenges like cost-effectiveness and environmental impacts, proposing multidisciplinary approaches involving IoT and advanced computational tools. By identifying actionable strategies, this work establishes a pathway for advancing SS technology as a global cornerstone for sustainable freshwater production. | ||
