Water scarcity is a growing threat due to population growth, urbanization, and climate change. This problem hinders sustainable development, making innovative solutions crucial distillation, which utilizes solar energy to convert brackish or saline water into clean drinking water, is emerging as a promising approach. While various solar designs exist, identifying the most efficient and cost-effective option for residential and industrial applications remains a challenge. This paper presents a comparative analysis, focusing on practical, between the traditional spherical solar still and an improved design incorporating a fan. We conducted our research in Baghdad, Iraq in June, utilizing real-world temperature and solar radiation data from the Iraqi Meteorological and Seismic Monitoring Authority. The key finding is that the inclusion of a fan within the solar system still significantly increases production efficiency by 31.8% compared to the conventional design. Furthermore, this study contributes valuable numerical simulations, empowering researchers to design efficient and low-cost solar stills. This technology holds particular promise for regions struggling with polluted water, especially in southern Iraq.
