The final zone is the constant, high-temperature zone near the exit at the top of the storage tank, where both Θl and Θs take values of unity. In the first zone, the filler is completely cooled by the cold molten salt ( Θl = 0) pumped into the storage tank, and thermal equilibrium exists between the two phases.

A solar thermal storage tank is an essential part of a solar thermal system, which harnesses the sun''s energy to produce heat. This heat is then stored in the tank and can be used for various applications such as space heating, domestic hot water, or industrial processes. In this section, we will discuss the definition and function of solar

Thermal energy storage at temperatures in the range of 100 °C-250 °C is considered as medium temperature heat storage. At these temperatures, water exists as steam in atmospheric pressure and has vapor pressure. Typical applications in this temperature range are drying, steaming, boiling, sterilizing, cooking etc.
The thermal energy-storage capability allows the system to produce electricity during cloudy weather or at night.

Most solar energy storage systems have a lifespan between 5 and 15 years. However, the actual lifespan depends on the technology, usage, and maintenance. Lithium-ion batteries generally have a longer lifespan (around 10-15 years), while lead-acid batteries may need replacement after 5-10 years (Dunlop, 2015).
