Concentrating Solar: Due Week 5 Calculate and compare the efficiency of a utility-scale single axis solar PV power station that operates on average at 16% efficiency with a concentrated solar thermal system that utilises a power tower. At that location the diffuse radiation averages 20% and the mirrors are 95% reflective. Assume the efficiency of conversion of the concentrated light to heat on the receiver is 91%, to produce steam at 610kPa and 560oC that enters the turbine. The turbine has an efficiency of 93%. The pump is ideal, and the condenser pressure is 6kPa
