Solar light condensing system

A sunlight collecting system in which sunlight is reflected by a plurality of heliostats onto a heat receiving portion having a heating medium circulated therein and then energy is drawn from the heating medium, characterized in that

• the sunlight collecting system is configured such that:
• the heat receiving portin is formed by assembling a plurality of modules,
• each of the modules includes an upper header having a linear shape, a lower header, and plurality of heat receiving receiving tubes connecting the two headers.
• each module is a three-dimensional module formed such that the lower header is formed in a substantially chevron shape in a horizontal planar view, the chevron shape having two bottom corners at the opposite ends of the lower header and a vertex at the center,
• each of the modules is having a substantially quadrangular shape in a front view by including the upper header, the lower header, and the plurality of heat receiving tubes connecting the upper header and the lower header,
• each three-dimensional module is formed such that a linear distance between the opposite ends of the lower header is shorter than that between the opposite ends of the upper header wherein adjacent the upper header the heat receiving tubes are aligned in a substantially straight line and wherein adjacent the lower header the heat receiving tubes are aligned in a substantially chevron shape formation;
• and wherein the modules are connected such that the upper headers are connected together forming a polygon and the lower headers are connected forming a star shape, and
• the heating medium circulates in the modules.
