The solar heat collector unit has the advantages that the heat absorption rate of the solar heat collector unit is increased to the greatest extent, the photo-thermal efficiency of the solar heat collector unit is greatly improved, the area of the solar heat absorber is greatly reduced, the size of the solar water heater is further reduced, the integrated combination space of the solar water heater and a building is widened, and meanwhile, the cost is greatly reduced. The sunlight reflecting plate in the technical scheme is planar, and cannot meet the high conversion rate of solar energy of the sunlight irradiation angle changing at any time.
