Solar stills are simple, small-scale desalination systems that use solar energy to evaporate seawater and condense freshwater. They are often used for producing potable water in off-grid or emergency situations.
• Applications: Remote or off-grid communities, individual households, small island nations, and emergency water supply.
• Advantages: Low cost, easy to install and maintain, requires no external power source, and is ideal for small-scale desalination needs.
