The invention discloses a solar heat source system and method. The solar heat source system comprises a transmitting insulation case, a reflector, a condensation device, a heat absorption device and a heat storage device, wherein a heat absorber is used for receiving solar radiation while receiving reflective condensation radiation; the transmitting insulation case is provided with a plane mirror and regularly distributed convex reflectors, and the surfaces of the two kinds of reflectors are crossed; the distribution rule of the convex reflectors is that: the center distance of two adjacent heat absorption tubes equals to triple the diameter of the convex reflectors; and the heat storage device outputs a heat storage medium or output heat energy through multiple paths of heat exchangers. According to the solar heat source system, the defect that traditional solar energy cannot be condensed by utilizing a reflector can be overcome, and the requirement for a temperature which is higher than that of boiled water can be fulfilled. The solar heat source system has good use effect and high solar utilization rate, can realize industrialized, standard, universal and serial production by utilizing the equipment, and belongs to the field of solar utilization.
