What material does a solar pond contain *?

A solar pond is simply a pool of water, which collects and stores solar energy. It contains layers of salt solutions with increasing concentration and therefore density to a certain depth, below which the solution has a uniform high salt concentration.

How does a solar pond work?

The solar pond works on a very simple principle. Similarly, in an ordinary pond, the sun’s rays heat the water and the heated water from within the pond rises and reaches the top but loses the heat into the atmosphere. The net result is that the pond water remains at the atmospheric temperature.
