A parabolic dish concentrating solar power unit has a reflector
diameter of 12.5
meters. It concentrates sunlight on a Stirling engine, heating the
helium working
fluid to 725ºC and rejecting heat to the ambient temperature 25ºC.
The engine has an
efficiency equal to one-half that of a Carnot engine operating
between these same
temperatures. Balance-of-system losses are 40% of the engine’s
output. What is the
power output of this unit given a direct beam insolation of 1
sun?
