Application of Solar Array and Analysis of Key Technologies in Deep Space Exploration

Since lunar exploration is initiated in 1958, after decades' development, great achievements have been made in the field of deep space explortation. The paper introduces the application of solar array in the fields of inferior planets exploration, superior planets exploration and celestial body landing exploration, analysis the critical technologies of solar array facing different conditions in these fields, thus points out the technical requirements of solar array and the critical problems that will be solved for different deep space exploration tasks, then generalizes the development trend of solar array technologies will be higher efficiency, environmental self-adaption, higher weight power ratio and capacity power ratio in deep space exploration.
