Water scarcity is a growing global challenge, particularly in areas where traditional water sources are inadequate. In such environments, sustainable solutions are needed to secure potable water access. Atmospheric water generators (AWG) can be a viable solution; however, most AWG require high humidity for operation, or lack design optimization, which limits their adaptability in low to moderate humidity regions or off grid regions. This paper presents an experimental study on a solar powered atmospheric water (AWG) generator using thermoelectric coolers (TECs) to condense water in low to moderate relative humidity (RH) from (35-65 %). The system consists of four TEC modules arranged in parallel with optimized airflows and heat dissipation mechanisms. This system was tested in both controlled laboratory condition and ambient outdoor settings, the proposed AWG achieved a maximum water generation rate of 25.5 ml/h at 65 % RH and 35 degrees C, and 11.5 ml/h at 35 % RH, demonstrating reliable performance in dry climates. Additionally, physicochemical analysis confirmed that the collected water is in accordance with WHO standards for drinking water. This study contributes to a self-powered, efficient AWG system tailored for semi-arid regions and highlights the feasibility of decentralized clean water solutions using renewable energy.
