(Received 11April 1977; in revised[orm 31 August 1977) Abstract--The total number of heliostats in the collecter field determines the approach to the optical simulation problem. For large central receiver systems, it is desirable to introduce a cell model which establishes an array of representative heliostats (see Ref.[l] for central receiver systems). We now have an arsenal of computer programs which allows us to optimize the arrangement of heliostats in the collector field subject to the approximations of the cell model. Each cell contains an arbitrary regular two dimensional array of heliostats. For practical reasons we have limited our current study of the 100MWe commercial model to four categories of heliostats arrangement; {1) radial cornfields, (2) radial staggers, (3) N.-S. cornfields, and (4) N.-S. staggers. The most important results from the 100MWe commercial model optimization study are: (1) Staggers are better than cornfields. (2) The increased cost of the tower and receiver subsystems has moved the solution to a larger cell size and a shorter tower. (3) No panels should be deleted from the south side of the cykindrical receiver, and t4) The collector field trims to a 360° configuration, The center of the collec
