“…Solar energy is the main energy source for the SPT system which consists of a series of well‐placed heliostats field that are used to direct the sun's rays all day long to the receiver which is placed at the top of the tower. The received reflected solar energy is processed based on conventional thermodynamic cycles which considers the effects of several parameters such as Stirling, Brayton, Gas Turbine, Ericsson, and others 2‐5 . These conventional thermodynamic cycles allow for a generated electricity 6‐8 .…”

The present study focuses on the optimization of solar tower power plant heliostat field by considering different heliostat shapes including rectangular, square, pentagon, hexagon, heptagon, octagon, and circular heliostat shapes. The optimization is carried out using an in-house developed code-based MATLAB program. The developed in-house code is validated first on a wellknown PS10 Solar Thermal Power plant having rectangular heliostats shape and the resulting yearly unweighted heliostat field efficiency of about 64.43% could be obtained. The optimized PS10 heliostat field using different heliostat shapes showed that the circular and octagon heliostat shapes provide better efficiency with minimum land area. The yearly efficiency is increased from 69.65% for the rectangular heliostat shape to 70.96% and 71% for the octagon and circular shapes, respectively. In addition, the calculated field area (land area) is reduced for the case of circular and octagon heliostat shapes with a gain of about 11.10% and 10.93% (about 42.0436 × 10 3 and 41.4036 × 10 3 m 2), respectively, in comparison with the PS10 field area.
