The computational model of a solar array on an irregularly curved surface for its application to a stratospheric airship was established using numerical discrete method, and parameter investigations under different heading angles of the airship were carried out. A layout optimization platform based on the solar radiation and solar array models was developed to optimize the area of the solar array, and the optimum layouts of the solar array under different heading angles were obtained. Results indicated that flat and curved surfaces can lead to large differences in the performance of the solar array, and the heading angles strongly affected the output power of solar cells. The proposed optimization method can help effectively reduce the area and weight of the solar array under the condition of sufficient output energy of the solar array. Moreover, the area of the solar array was reduced by 21.9% when the heading angle was 90°.
