Abstract :
Curved surface renewable solar cell is applied to provide a near space airshippsilas energy system the power to drive the high altitude electromotor and propeller in a long term. The solar flux incident on the solar cell is calculated through integral transform and some revised correlations from tilted surface solar radiation flux calculations. In view of the solar radiation flux and the wind speed fluctuation and randomicity, wavelet analysis and genetic algorithm aided neural networks are combined to make the solar radiation flux predictable and real-time with higher precision than solar constant radiation spatial interpolation.
