    • An actuated feedforward controlled solar tracker system including a sub-frame supporting at least one solar panel, a post supporting the sub-frame, and a linking mechanism connecting the sub-frame and post, where the linking mechanism includes a first axle, second axle and body member. The linking mechanism's first and second axles are disposed orthogonal to each other and are separated by the body member.

    • Photovoltaic panel support base rotating simultaneously around two axes, i.e. around an horizontal axis (North - South direction) for the continuous correction of the swivel angle (ß), and around a vertical axis (East - West direction) for the continuous correction of the hour angle (?), the solar deviation (d) and the azimuthal surface (Y). The assembly comprises the tower (1), the base (2) with round profile, used for the anchorage and the seat of the assembly, the first drive mechanism (3) with ball bearings (16) for the rotation of the upper part around a vertical axis, the cantilevers' support assembly (4) of V shape, the rod (5), the second mechanism (7) for the rotation of the photovoltaic panels plane around an horizontal axis, the rotation axis (6) of the photovoltaic panels plane, the beams (8) of changing thin walled profile H and the series of transverse thin walled beams (9) of U profile. The frames of the photovoltaic panels rest on the frame formed by the U-shaped beams. The strong wind which falls at the photovoltaic panel plane is received and transmitted to the inner part of the construction, from one hand by the beams assembly (8) of shape H and from the other by the V-shaped assembly of the cantilevers (4). The strong forces' flow to the increasing profiles of the two assemblies (8) and (4) significantly decreases their strength to the inner part of the construction and as a result the two rotating drive mechanisms (3) and (7) substantially receive minimum dynamic stressing having the form of contact voltages (Hertz) created to their ball bearings (16). The electric motors of the two rotation mechanisms are driven by means of satellite control in order for the combination of ß, ?, d and Y to provide the instantly desired result cos? = 1 or ? = 0, i.e. the incident solar radiation to always be vertical with regard to the panels plane.

    • Longitudinally adjacent plane mirrors (106?114) are pivotally interconnected in a columnar array (56) by non-stretching linkages (120) which constrain movement of the mirrors such that their normal vectors (115) remain parallel. Pivotable couplings (122, 124) in two mirrors permit movement of the mirrors with respect to mutually perpendicular axes (x, y) and prevent movement of the mirrors with respect to a third axis (z). Two actuators (117A, 117B) coupled to one of the pivotable couplings controllably move a selected mirror with respect to the mutually perpendicular axes (x, y). A first frame (116) couples the mirror columns together so that movement of the selected mirror moves all the mirrors in unison. The actuators controllably move the mirrors to orient the normal vectors such that the mirrors specularly reflect incident light in a preselected direction.
    • 纵向相邻的平面镜(106〜114)通过非拉伸连杆(120)以柱状阵列(56)枢转地相互连接,这限制了反射镜的运动,使得它们的法向矢量(115)保持平行。 两个反射镜中的可转动联轴器(122,124)允许反射镜相对于相互垂直的轴线(x,y)移动,并防止反射镜相对于第三轴线(z)移动。 联接到可枢转联接器之一的两个致动器(117A,117B)可相对于相互垂直的轴线(x,y)可控地移动所选择的反射镜。 第一框架(116)将镜柱连接在一起,使得所选择的镜子的运动一致地移动所有的镜子。 执行器可控制地移动反射镜以使法向矢量定向,使得反射镜以预选的方向镜面反射入射光。
