Study the effect of the external reflector on the efficiency of pyramidal solar still (PSS)‎ in Basra city-Iraq

الملخص EN

This research a pyramidal solar still (PSS) has been manufactured in Basra city.

The experimental investigation was carried out on solar still under the same conditions.

The pyramidal solar still consists of a basin area of (0.25 m2).

Some additions have been made and examined in order to increase the performance of the still.

external reflector (dish covered with aluminum paper) was used to concentrate the solar rays towards certain region of the solar still(constructed manually in our laboratory).

The maximum efficiency has been got of the experimental still varies from (40% -70% ) pyramidal solar still
