A method for the automated control of a solar protection installation (INST), comprising:reflecting slats (B1, B2, B3) having parallel longitudinal axes, the slats having a face (F) provided with teeth (D) which flanks (Fl), intended to be exposed to the light rays, called “useful” flanks, lie in parallel planes (P1, P2, P3, P4);means (CPU, CLK, ASUN) for determining a main direction of incidence (ASUN1; ASUN2) of the light rays on the slats; anda motor (MOT) for tilting the slats at least substantially about their longitudinal axis,the method of control including a step of automatically tilting the slats so as to orient the plans of the useful flanks depending on the main direction of incidence of the light rays.
