The invention relates to a solar heat collection wall which comprises a casing, solar heat collection panels, an input pipeline and an output pipeline. A plurality of solar heat collection panels are sequentially fixed on the inner side of the casing from top to bottom and meet the requirement that the solar heat collection panels are approximately and vertically fixed with solar rays, one ends of heat conduction pipes or heat conduction cavities located on the rear sides of the solar heat collection panels are collected to be communicated with a main input pipe, and the other ends of the heat conduction pipes or the heat conduction cavities are collected to be communicated with a main output pipe. According to the solar heat collection wall, a single wall or a plurality of walls can be parallelly fixed on a sunny slope wall of a building, enough sunny areas are provided by means of supporting of the building, and solar energy resources are utilized as much as possible. The solar heat collection panels in the solar heat collection wall keep perpendicular relationships with the solar rays so that the heat energy conversion efficiency is highest. Angles of the solar heat collection panels in the solar heat collection wall can be arranged to be rotatable to adapt to different daylight deflection angles in four seasons. The solar heat collection walls are combined to form an outer wall with a decorative effect, and ornamental values are achieved.
