Abstract: In order to fully utilize the total heliostat reflected area and collect the maximum solar radiation for central receiver plants, one should minimize the heliostat shaded and blocked areas. This condition must be satisfied during the day and around the year. Based on the criterion of no blockings and no shadowing, the heliostat fields is subdivided into zones. Each zone is characterized by a predominant shadowing or blocking effect. The minimum yearly radial spacing between two adjacent heliostats for no blocking and no shadowing condition is calculated for all zones. Results for sites at latitude angles of 101°, 20°, 20° and 40°, and for daily operation periods of 4, 6 and 8 hours are obtained.
