Energy, 1981, vol. 6, issue 6, 485-501

Abstract: A net energy analysis (NEA) of the Solar Power Satellite System is performed. Two options are compared using either silicon (Si) or gallium-aluminum-arsenide (Ga-Al-As) photovoltaic cells. The analysis is based on the DOE/NASA reference system. Maintenance and material energy costs are considered and are shown to be valid. Results show a net energy ratio (electrical output vs primary thermal input) of the order of 2–5 for the silicon cell option and 14–18 for the gallium-aluminum-arsenide option.
