Coastal salt production, involving solar evaporation of seawater, followed by artificial evaporation of salt using the open-pan technique in structures known as 'salterns'. [ 3 ] Inland salt production , using brine from natural brine streams flowing over buried salt deposits that were pumped up from the ground and evaporated using the open-pan ...
Solar salt may refer to: Sea salt, a salt produced by the evaporation of seawater; Solar salt, a eutectic molten salt mixture which is used for thermal energy storage
Modern sea salt production is almost entirely found in Mediterranean and other warm, dry climates. [5] "Fleur de sel" sea salt, Île de Ré. Such places are today called salt works, instead of the older English word saltern. An ancient or medieval saltern was established where there was: Access to a market for the salt [6]
Solar Evaporation Ponds in the Atacama Desert. The largest operating solar pond for electricity generation was the Beit HaArava pond built in Israel and operated up until 1988. It had an area of 210,000 m² and gave an electrical output of 5 MW. [3] India was the first Asian country to have established a solar pond in Bhuj, in Gujarat.
Salt pans are shallow and open, and metal pans are often used to evaporate brine. They are usually found close to the source of the salt. For example, pans used in the solar evaporation of salt from seawater are usually found on the coast, while those used to extract salt from solution-mined brine will be found near the brine shaft.
The total salt precipitated in solar evaporation at the Dead Sea plants is tens of millions of tons annually, but very little of the salt is marketed. Today, salt from groundwater brines is generally a byproduct of the process of extracting other dissolved substances from brines and constitutes only a small part of world salt production.

Solar process heating systems are designed to provide large quantities of hot water or space heating for nonresidential buildings. [21] Evaporation ponds are shallow ponds that concentrate dissolved solids through evaporation. The use of evaporation ponds to obtain salt from sea water is one of the oldest applications of solar energy.
