This paper conducted an experimental study of a laboratory-scaled 2-stage parabolic dish-Stirling engine. Experimental investigation of the system was performed, using an actual sun and a 2-stage parabolic dish concentrator as a heat source. Results from the performance testing by using a generator with a solar radiation and a double reflection parabolic dish solar concentrator in May 2014 indicated that the maximum concentrator efficiency is 26.291 %, the engine produced a maximum power of 0.359 W at 55.6 rpm, electrical power of 0.27 W, the generator efficiency at the maximum of 79.021 %, and the maximum overall brake thermal efficiency of 0.25033 %, approximately. The average heat input to concentrator is 1936.07 W and to the engine in an average of 180.28 W, respectively. The gross solar-toelectric conversion efficiency is 3.71 %. [ABSTRACT FROM AUTHOR]
