When the sun''s rays contact the bottom of a shallow pool, they heat the water adjacent to the bottom. When water at the bottom of the pool is heated, it becomes less dense than the cooler water above it, and convection begins. Solar ponds heat water by impeding this convection. Salt is added to the water until the lower layers of water become completely saturated. High-salinity water at the bottom of the pond does not mix readily with the low-salinity water above it, so when the

The capacity of a solar pond power plant depends on the size and heat storage capacity of the solar pond, as well as the power generation equipment used in the system. Solar pond power generation can be suitable for remote areas with ample sunlight and a need for decentralized power generation. However, it has certain limitations.
It is possible to set up a salinity gradient in a solar pond in a number of different ways. This method is one of the simplest and most commonly used in the world. A freshwater level of 1.3 m from the bottom of the solar pond is approximately equal to the thickness of the storage zone and half of the gradient layer.
