Compare the efficieney of a utility-scale single axis solar PV power station that operates on average at 15% efficiency with a concentrated solar thermal system that utilises a power tower. At that location the diffuse radiation averages 20% and the mirrors are 90% reflective. Assume the efficiency of conversion of the light to heat on the receiver is 90%, to produce steam at 600kPa and 600°C that enters the turbine. The turbine has an efficiency of 90%. The pump is ideal, and the condenser pressure is 4kPa.
