Under development for launch in July 1998, Deep Space One (IX 1 ) is the first flight of NASA’s New Millennium Program, chartered to validate selected technologies required for future low-cost space science programs. Advanced technologies chosen for validation on DS 1 include solar electric propulsion, high-power solar concentrator arrays, autonomous on-board optical navigation, two low-mass sc...

solar radiation data play an important role in solar energy relevant researches. these data are not available for some locations due to the absence of the meteorological stations. therefore, solar radiation data have to be predicted by using solar radiation estimation models. this study presents an integrated artificial neural network (ann) approach for estimating solar radiation potential over...

A solar-driven water-splitting cell is generally comprised of light absorbers, electrocatalysts, membrane separators and an electrolyte solution in a specic system geometry. The overall solar-to-hydrogen conversion efficiency of such a system depends on the performance and materials properties of all the individual components as well as the design of the system. Signicant research efforts are...

this paper proposes a new configuration for solar energy conversion systems. one challenging issue of the photovoltaic (pv) systems is partial shading, and in this paper module integrated converters (mic) are used to overcome this problem in pv arrays. a few boost converters are employed as mics to mitigate the shading effect. furthermore, to reduce the cost and to increase the system performan...

A solar chimney is designed and tested to pump outside air through an underground cooling tube during summer for building cooling. Both theoretical analysis and experimental results show that the solar chimney can be used to power the underground cooling system during daytime without use of electricity. This paper presents the theoretical design principals of the solar chimney, detailed experim...
