The invention relates to the solar engineering, particularly to devices for heat-transfer agent heating at the expense of the solar energy. The solar heat collector-accumulator comprises a heat-insulated body (1) with a transparent coating (2), lateral walls (3) and a back wall (4), heat-transfer agent admission and drainage branches, a light-absorbing partition (7), installed between the transparent coating (2) and the back wall (4), forming two chambers (8 and 9). The chamber (9) between the light-absorbing partition (7) and the back wall (4) is filled with heat-accumulating material with phase transition in the working temperature range. The collector-accumulator also comprises flow-type heat exchangers (10, 11, 12) connected in parallel to the heat-transfer agent admission and discharge branches, at the inlet of each of them being installed shut-off-and-regulating elements, one heat exchanger (12) is placed in the chamber (9) between the light-absorbing partition (7) and the back wall (4), into the layer of the heat-accumulating material. At least two heat exchangers (10, 11) are placed in the light-absorbing partition (7) covering the whole surface thereof, at least one of which is made multichannel. In the chamber (9) with heat-accumulating material may be placed a breather (20), communicating with the atmosphere. The heat-insulated body (1) and/or the transparent coating (2) and/or the light-absorbing partition (7) and/or the flow-type heat exchangers (10, 11, 12) are made of glass-reinforced resin and/or composites.
