Energy Eng. 2012;134(4):041007-041007-9. doi:10.1115/1.4006891 Figure Legend: The solar dissociation experimental system and associated losses. The arrows pointing left from the system (red arrows) comprise the receiver losses—due to heat losses and reflection from the cavity. Accounting only for these losses gives the receiver efficiency. Adding these to the flux spillage, dish reflectivity, tracking error and heat exchanger losses gives all the losses in the system, which are accounted for in the solar-to-chemical efficiency.
