<p><P>PROBLEM TO BE SOLVED: To improve heat collecting efficiency of sunlight received by heliostats. <P>SOLUTION: The method of collecting sunlight in a multi-tower beam down type light collecting system has a selecting process of towers. In the field of having a plurality of beam down type light collecting towers, the multi-tower beam down type light collecting system is a system of secondarily reflecting light primarily reflected from the heliostats around each tower 4 by reflectors 2 of an upper part of the tower 4, and collecting it on a receiver 3 on the ground, and the tower selecting method is a process of comparing magnitudes of amounts of light received in the receivers 3 of the towers 4 when the heliostats 1 in optional positions have received sunlight and the sunlight is collected in two optionally selected towers 4, 4, and selecting a tower 4 having the relatively larger amount of light received. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
