advantages of using more efficient Stirling dishes rather than less efficient solar panels http://hackaday.com/2009/09/08/diy-solar-panels/
Unlike conventional photovoltaic (PV) solar cells which register at between 10% and 18% efficiency, dish/Stirling systems are capable of converting around 25% of available energy from sunlight into electricity.
A dish/Stirling system includes two components; the solar dish, which is simply a parabolic mirror or set of mirrors, and a Stirling engine, a closed-cycle engine that operates silently using any heat source. Efficiency for the Stirling engine approaches maximum theoretical efficiency for any engine, known technically as Carnot cycle efficiency.
