In order to provide a converging solar module which achieves effective electricity generation, as well as significant reduction of costs and driving energy required to track the sun, a cell stage 20 carrying solar cells 16 is provided opposite to converging lenses 10. Some elastic members are provided between a pair of adjacent side edges of the cell stage 20 and corresponding side walls of a vessel 18. Along the other pair of side edges, stage driving bars 24 are provided. The stage driving bars 24 are moved horizontally by opening/closing operations of feeder valves X1, X2, Y1, Y2 and drain valves X3, X4, Y3, Y4 thereby moving the cell stage 20 horizontally in the direction perpendicular to the direction in which the stage driving bars 24 have moved. With an action of the elastic members 22 and the stage driving bars 24, the position of the cell stage 20 is adjusted such that the solar cells 16 thereon are brought into a position where converged spots 14 are formed.
