Dear Hhaleel

The temperature control in the solar pond depend mainly in controlling the salt concentrations in the pond layers in addition to the time of exposure to sun

I found this indian professor is amazing in explaining the solar ponds

you can use temperature data logger

The floor of the solar pond should be black to absorb as much solar energy as possible. The salt solution should be saturated at the bottom layer, with fresh water at the top layer. The maximized concentration of salt in the lower layer allows it to be denser than the top layer despite its higher temperature, thereby minimizing mixing.

Dear all

In addition to all the mentioned points by Dr Denur, when you build a solar pond you must minimize the effect of shadow as possible.

dear  sir Deur and sir Miqdam  i thank you for your answer s  but what about air wind at the top of the pond .

Strong winds may create waves that force mixing of the less dense cooler surface fresh water layer with the more dense salty deep layer (the density of a hot saturated salt solution exceeds that of cool fresh water). The problem of wind can be minimized by placing windbreaks around the solar pond. A windbreak has at least some effect at distances up to approximately 20 times its height. The windbreaks need not be tall enough to block much sunlight, and if made of transparent material such as Lucite they can be taller and may even enhance solar-pond performance.

Dear Colleagues

In solar salty ponds, a transparency cover must be used to cover the pond in high wind days and in dusty days as well. The dust and pollutants particles can reduce the solar radiation reaches the pond's bottom.
