In the present study, we are looking for a low cost and highly efficient system. If several Tokyo Tech beam down systems are placed adjacently (multi-tower system), it is expected that utilization efficiency of heliostats will increase by using of optimum layout and operation. In this report, we show the superiority of the multi-tower beam down system. For that, we simulate heliostat field efficiency in a layout of repeated equilateral triangles and calculate the variation in the receiver incidence power on both multi-tower control and single-tower control by using TSUBAME-sol (multi-purpose solar concentration simulator). In the result, we find that multi-tower control is more effective than the single-tower control as the heliostat field efficiency and the receiver incidence increases about 10% in average and 20% tops.
