The contemporary challenge facing human society is the pressing need to satisfy the substantial demand for freshwater, which is dwindling rapidly due to the burgeoning human population and rapid urbanization. Solar stills offer an economical means of obtaining fresh water, as they rely solely on the abundant and freely available energy from the sun for operation. However, a significant constraint in conventional solar stills lies in the requirement to maintain a large surface area of water with minimal water depth. To address this constraint effectively, inclined solar stills emerge as a preferred solution, as they offer a large surface area of water while maintaining a shallow water depth. In pursuit of enhancing the performance and efficiency of inclined solar stills, numerous efforts have been directed towards increasing the free surface area of water. Studies have shown that passive inclined solar stills yield distillate ranging from 1000 to 8100 ml/m2, while active inclined solar stills produce distillate yields ranging from 1045 to 9000 ml/day. This review aims to analyze the current status of various designs in inclined solar stills with the objective of inspiring further research in inclined solar still technology. By delving into the present advancements and challenges in this field, this review endeavors to foster innovation and development in inclined solar still technology to effectively address the growing demand for fresh water.
