This research explores the design, development, and performance evaluation of a compact, standalone solar still system for efficient water purification. With the growing challenge of freshwater scarcity worldwide, solar stills offer a sustainable approach by harnessing solar energy for desalination and purification. The proposed system is designed to be compact, affordable, and easy to install, making it particularly suitable for remote and off-grid locations. The construction of the solar still focuses on optimizing its dimensions to enhance solar absorption and condensation efficiency. Key design elements include a high-transparency glass cover for improved sunlight penetration, a black-coated basin to maximize heat absorption, and a well-sealed structure to reduce heat loss. A condenser composed of thermally conductive materials is incorporated to enhance the speed of condensation. To evaluate its efficacy, performance tests were executed under diverse climatic conditions, quantifying variables such as water output, sun radiation, ambient temperature, and humidity. The results demonstrate that, under ideal conditions, the system may produce up to 6.7 l of cleaned water per square metre per day, with maximum efficiency occurring during periods of high solar intensity. This study highlights the potential of a compact, standalone solar still as a reliable and sustainable solution for water purification, especially in regions facing freshwater shortages and lacking electricity access.
