This study investigates the feasibility of using a hybrid photovoltaic (PV)-wind-battery power system to sustain a Mars base under varying seasonal and climatic conditions. The Mars Climate Database was utilized to simulate the effects of seasonal changes, diurnal cycles, and dust storms on the system's power generation.
The analysis shows that a single 1,000 m^2 PV array, a 33.4 m diameter wind turbine, and a 312 kWh battery can support a six-person Mars base across 32.1% of the Martian surface during the equinoxes and solstices, including global dust storms. This coverage can be expanded to 51.7% by using three sets of PV arrays and wind turbines.
Additionally, 24 out of the 47 proposed landing sites from the "First Landing Site/Exploration Zone Workshop for Human Missions to the Surface of Mars" can be supported throughout the solstices and equinoxes by a single PV array, wind turbine, and battery, even during global dust storms. The top three sites with the highest energy production potential are Hebrus Valles, Huygens Crater, and Noctis Labyrinthus.
The wind turbine's contribution to the total power production ranges from 0-20.9% during the solstices and equinoxes without global dust storms, and increases to 8.4-89.2% during global dust storms, highlighting the importance of incorporating wind power as a backup to the PV system.
These findings are expected to guide further research on hybrid renewable power systems for Mars exploration and support the development of sustainable human settlements on the Martian surface.
