摘要
A solar concentrating arrangement that does not rotate about a vertical axis has a primary linear focusing element 101 able to rotate 104 about a horizontal axis 103 and a linear array of secondary focusing elements 107 able to rotate about an axis 108 which is orthogonal to that of the primary element. The elements can be parabolic or Fresnel mirrors or cylindrical lenses that focus light on target areas 302 of an energy convertor 105. Extra mirrors 303 help reflect light when the sun is considerably off-axis. The secondary elements 107,303 can also be curved in a transverse direction, depending on the focal length of the primary element 101.
