The invention relates to the technical field of solar heat utilization and discloses a solar flat plate heat collector. The heat collector comprises a front cover plate, a rear cover plate and a frame which are sealed to form a sealed cavity. A plurality of heat absorbing plates provided with dip angles which are local best vertical dip angles are arranged in the sealed cavity, each heat absorbing plate is connected with a heat collecting tube, and two ends of the heat collecting tube are respectively fixed on the frame. When the solar flat plate heat collector is installed in most of places facing due south or due south +/- 30 degrees, only the dip angles of the heat absorbing plates are required to be adjusted to be the local best vertical dip angles. When the solar flat plate heat collector is installed in a few places facing non-due south or due south +/- 30 degrees, the solar flat plate heat collector is first rotated for 90 degrees clockwise or anticlockwise, then the heat absorbing plates are adjusted
