Is there an ideal distance between solar stills for increased output?

Solar Stills Arrangement

When building multiple solar stills, it’s essential to arrange them to maximize sunlight exposure. A commonly recommended spacing is 1-2 meters between each still, depending on the size and shape of the stills. This distance allows for minimal shading and ensures that each still receives a substantial amount of direct sunlight, resulting in increased water output. Keep in mind that too close of a spacing can lead to shading issues, while too far apart can reduce overall water collection efficiency.

Solar Stills Orientation

Solar stills should be oriented to face the equator, typically south in the northern hemisphere, to maximize sunlight exposure. The stills should also be positioned to minimize direct sunlight on the water surface during the hottest part of the day, which can cause evaporation and subsequent loss of water. A tilt of about 10-20 degrees from the horizontal can help achieve this balance.

Stills Placement in Relation to Obstacles

When building solar stills, it’s crucial to consider the placement of the stills in relation to obstacles, such as trees, buildings, or rocky terrain. Avoid placing stills near structures that can cast shadows on the stills during critical hours, as this can significantly reduce water output. Instead, position the stills near open areas or use structures to create a clear path for sunlight to reach the stills.
