    This research delves into the quantitative impact of design modifications on solar still performance, specifically examining the role of fins on the glass cover. Comparative analyses were conducted on two solar stills, SSref (Solar Still reference) and SSmod (Solar Still modified with fins), considering temperature variation, energy transfer, energy evaporation, hourly water output, and internal efficiency. SSmod consistently exhibited superior performance, maintaining lower temperatures (peak difference of 10 °C), achieving an average energy transfer of 555 W/m², a higher energy evaporation rate (335 W/m² on average), and an increased hourly water output (0.59 mL peak). The internal efficiency for SSmod averaged 0.741%, surpassing SSref's 0.713%. These quantified results highlight the crucial contribution of fins in enhancing distillation processes, providing a valuable foundation for designing solar stills with improved energy efficiency and resource utilization

    Cooling Effect on a solar still condenser

    A data logging system has been deployed to monitor two solar panels positioned at distinct inclination angles. This system records crucial parameters such as current, voltage, solar radiation incident on the panels, and panel temperatures. Comprising an Arduino microcontroller, a current sensor, a current and voltage sensor, and a Memory Card, the data logger captures and stores data in .txt files at 20-minute intervals. Employing a real-time acquisition system, the obtained results indicate that the data logger effectively archives and presents a wealth of information about solar panel characteristics. Notably, the data reveals superior performance of the solar panels at a 35-degree tilt angle compared to 32 degrees during April in the Ouargla region of Algeria
