The invention relates to a method for positioning a reflective surface in relation to the sun, so that the reflected light falls on a target point, using a solar sensor and a two-axes angular mechanism. The method can be used to position a reflective surface (R) in relation to the sun (S), said reflective surface being mounted on a mechanical system having two axes of rotation (azimuth-elevation), using a solar sensor (1) that is positioned facing the reflective surface in a fixed orientation. The solar sensor measures the angles (2) formed by the projected incident light vectors in relation to two orthogonal planes (4). The method is applied independently and simultaneously to both axes of rotation and can be used to calculate the relative position of the ray (3) reflected from the reflective surface in relation to the orthogonal planes (4) of the solar sensor (1). Once the relative position is known, the position of the reflective surface (R) is altered in both independent axes, by means of a suitable movement of two motors, until the relative position (2) of the reflected ray (3) coincides with the perpendicular of the solar sensor (1).
