description: The global water crisis demands innovative solutions, and solar desalination is a promising avenue. However, traditional systems often suffer from low yields. This study centres on the development, assessment, and economic feasibility of the Enhanced Hybrid Solar Still (EHSS), a pioneering approach to sustainable clean water production. Integrating photovoltaic technology, the EHSS targets a minimum daily output of 15 L/m2. Computational Fluid Dynamics (CFD) simulations guide the design optimisation, identifying an optimal configuration of 4 mm basin thickness, a 2 mm glass cover thickness, and a 56° slope. The EHSS is a single component that comprises of passive operation and advanced components integration, including monocrystalline solar panels, a hybrid MPPT inverter, a deep cycle battery, and a custom water heater, to enhance the yield. The EHSS undergoes a comprehensive assessment encompassing distillate quality, efficiency, and economic viability. In passive mode operation (solely using solar radiation), clean water yields range from 4.7111 L/m2·day to 2.1309 L/m2·day. Transitioning to active mode operation (employing photovoltaics and additional components) significantly enhances yields to a range of 19.7 L/m2·day. Impressively, the EHSS consistently delivers an average daily water yield of 16.85 L/m2, and also its purity meets World Health Organization standards for drinking water. The PV systems exhibit a charge rate of 14.28  per hour on clear days and 9 to 11  per hour on semi-cloudy days, with the battery depleting at 16.66  per hour at 70 °C operational temperature. Comparative analysis against traditional systems showcases an efficiency increase from 25.61  to an outstanding 64.01  for the optimised EHSS (PV system and appurtenances). A strong correlation (coefficient of 0.9701) between experimental and simulation results indicates robust relationships. Over a 20-year lifespan, cost analysis reveals a per-litre cost of 0.0892 US dollars for the EHSS, compared to 0.0374 US dollars for traditional systems. Extended lifespans further underscore the economic feasibility of the EHSS, emphasizing its role in providing sustainable clean water solutions. © 2024 Elsevier B.V.
