In the study of Stirling power generation technology, Hu [10,11] has developed an energy system that uses solar energy as the driving energy to drive Stirling generator for power generation in the daytime and thermal storage unit (TSU) as the driving energy to drive Stirling for power generation at night. The system is simple and convenient.
It seems that solar energy can be one of the best alternatives to non-renewable sources due to its unlimited and non-polluting nature , .The amount of energy from sunlight reaching the earth in one hour is equivalent to the energy used by people in one year .This form of energy can be converted into electrical energy using photovoltaic (PV) and concentrated
The solar energy can be used to produce electricity, heat water and homes, also, the development of thermal energy storage technology suggests that some of the unused solar energy could be stored
Two-tank direct storage was used in early parabolic trough power plants (such as Solar Electric Generating Station I) and at the Solar Two power tower in California. The trough plants used mineral oil as the heat-transfer and storage
4.1.1.1.1 Solar thermal storage. Solar thermal energy is usually stored in the form of heated water, also termed as sensible heat. The efficiency of solar thermal energy mainly depends upon the efficiency of storage technology due to the: (1) unpredictable characteristics and (2) time dependent properties, of the exposure of solar radiations.
Solar thermal power (STP) technology is a promising renewable energy power generation technology, which has attracted lots of attention. When the water is used in the STP system as the heat transfer fluid (HTF), it can generate high-temperature and high-pressure steam to drive the steam turbine, greatly reducing the heat transfer process''s energy loss.
Solar collectors and thermal energy storage components are the two kernel subsystems in solar thermal applications. Solar collectors need to have good optical performance (absorbing as much heat as possible) , whilst the thermal storage subsystems require high thermal storage density (small volume and low construction cost), excellent heat transfer rate
Solar photo-thermal power generation refers to use large it with thermal storage as a valid method to increase the flexibility of the system and reduce costs; (3) suggested hybrids, both with
Thermal energy storage (TES) is a key element for effective and increased utilization of solar energy in the sectors heating and cooling, process heat, and power generation. Solar thermal energy shows seasonally (summer-winter), daily (day-night), and hourly (clouds) flux variations which does not enable a solar system to provide heat or

Roof-mounted close-coupled thermosiphon solar water heater. The first three units of Solnova in the foreground, with the two towers of the PS10 and PS20 solar power stations in the
Liu et al. (2020), in a crosstalk analysis of the thermal performance of sensible and latent heat thermal energy storage systems in CSP plants,” developed new ways of selecting the thermal storage materials for the concentrated solar power (CSP) plant” .
For the generation of electricity in far flung area at reasonable price, sizing of the power supply system plays an important role. Photovoltaic systems and some other renewable energy systems are, therefore, an excellent choices in remote areas for low to medium power levels, because of easy scaling of the input power source , .The main attraction of the PV
A research method of solar medium and low temperature heat storage technology was proposed by combining simulation and experiment investigation.

STSs are TES systems where the source of heat is provided by the solar field, capturing the excess of energy not directly converted into power or other useful utility. As such, most TES
In particular, this Solar thermal energy is acquiring significant escalating portions of global generation of power. Thermal power plants based on solar energy under construction or completed have increased significantly as a way of energy production in the USA, Southern Europe, Australia, and Africa.
It is important to note that, while using renewable energy sources such as solar power, storage methods based on non-recyclable materials or methods that consume significant amounts of energy may

For solar thermal power generation, the functions of a storage system are to adjust loading, reduce the device capacity and investment cost, further improve solar resources and device use ratio, and
Thermal energy storage (TES) is a technology that reserves thermal energy by heating or cooling a storage medium and then uses the stored energy later for electricity generation using a heat engine cycle (Sarbu and Sebarchievici, 2018) can shift the electrical loads, which indicates its ability to operate in demand-side management (Fernandes et al., 2012).
The heat capacity increases with the increase of temperature, and the heat storage density increases. The heat storage density is 1218.75 kJ/kg (1000°C). Heat capacity increases with temperature due to intensified lattice
Thermal energy storage (TES) is a technology that stocks thermal energy by heating or cooling a storage medium so that the stored energy can be used at a later time for heating and cooling
