The energy of the solar airship comes from the solar cell array, and the amount of solar radiation received by the array determines the endurance of the airship. The rigid crystalline silicon cells and flexible thin-film cells used in the airship were modeled. By considering the size and shape of the actual panel cells, the differences in received energy between the oblique plane array of the rigid cell and the curved array of the flexible cell were compared. The effect of airship size on the received energy of the two arrays was also analyzed. Then, four oblique plane array arrangements for rigid cells were set up, and the effect of the size and shape of the solar panels in the oblique plane array on the received energy was compared. The results show that the oblique plane array of the rigid cell at the low and middle latitudes receives higher solar radiation energy than the curved array of the flexible cell throughout the year, and the opposite is true in the high latitude area. For rigid cells, the size of the solar panels in the circumferential direction of the airship will significantly affect the solar radiation energy received by the oblique plane array. In low-latitude areas, the length of the solar panel in the circumferential direction should be increased to obtain more radiation energy, while in high-latitude areas, the length should be reduced.
