Solar stills are simple and eco-friendly devices used for desalination and purification of water by utilizing solar energy. The performance of a solar still is significantly influenced by several operating parameters, among which the inclination angle of the glass cover plays a crucial role. This review paper presents a comprehensive analysis of solar stills with different inclination angles and their effects on productivity, heat transfer, condensation rate, and overall efficiency. Various experimental and theoretical studies reported in the literature are examined to identify the optimum inclination angle under different climatic conditions. The review highlights that the inclination angle affects solar radiation absorption, condensate flow, and thermal losses, thereby influencing freshwater yield. It is observed that the optimal angle generally depends on the geographical location, latitude, seasonal variation, and design configuration of the solar still. Furthermore, the paper discusses different types of solar stills, modifications adopted to improve performance, and comparative analyses of inclined and conventional designs. The findings of this review provide useful insights for researchers and engineers in designing efficient solar still systems for sustainable freshwater production in water-scarce regions.
