The casing includes a frame ( 12 ) having two side plates ( 14 a, 14 b ) and inlet and outlet end plates ( 16 a, 16 b ), a base plate ( 11 ) hermetically assembled to a bottom end of the frame. Inlet and outlet partition plates ( 15 a, 15 b ) arranged in the casing divide an inner space of the casing into an inlet region ( 31 ), an outlet region ( 41 ), and a heat-collecting region ( 211 ). The solar collector includes a heat-absorbing set ( 22 ) and a transparent panel ( 13 ) hermetically assembled to a top end of the frame. The heat-absorbing set is arranged in the heat-collecting region and divides the heat-collecting region into an upper heat-storage cavity ( 24 ) and a lower heat-absorbing cavity ( 25 ). The inlet and outlet regions communicate with opposite ends of the heat-absorbing cavity of the heat-collecting region, respectively.
