Conclusions This paper proposes a dish solar thermal power system equipped with lunar regolith heat storage to achieve a continuous and efficient energy supply on lunar days and nights. A theoretical model using finite-time thermodynamics analysis is established in MATLAB Simulink to analyze system performance.
The resulting beam of concentrated sunlight is reflected onto a thermal receiver that collects the solar heat. The dish is mounted on a structure that tracks the sun continuously throughout the day to reflect the highest percentage of sunlight possible onto the thermal receiver.

The dish/engine system is a concentrating solar power (CSP) technology that produces smaller amounts of electricity than other CSP technologies—typically in the range of 3 to 25 kilowatts—but is beneficial for modular use. The two major parts of the system are the solar concentrator and the power conversion unit.
Thermal energy storage. is integral to CSP because it enables this heat-based form of solar to generate electricity at night and during cloudy periods, so it is a flexible and dispatchable form of solar energy.
In solar thermal systems, concentrators are used to extract the energy from solar irradiation and convert it into useful form. Among different types of solar concentrators, the parabolic dish solar concentrator is preferred as it has high efficiency, high power density, low maintenance, and potential for long durability.
