PURPOSE:To enable to fold the title panel into a small size at the time of storage and to enhance the focusing ratio thereof at the time of expansion of the panel, by a method wherein each end on one side of plural support rods for positioning is jointed to a plate to which a solar cell is fixed, and each of the other ends thereof is jointed to a focusing lens or a reflector, in such a manner that the support rods are rotatable around the joints, and at the same time, one or more of the support rods for positioning is/are designed to be able to expand and contract. CONSTITUTION:Solar cells 2 are respectively disposed at nearly each focal position of linear Fresnel lenses 1, which focus linearly, and heat radiating plates 3 wider than the solar cells 2 are junctioned to the back of the solar cells 2. The interval between each linear Fresnel lens 1 and each solar cell 2 is held by support rods 4 and 5. The length of each support rod 4 is a fixed one, one end thereof is jointed to the linear Fresnel lens 1 and the other end thereof is jointed to the heat radiating plate 3, and the support rod 4 is jointed to the linear Fresnel lens 1 and the heat radiating plate 3 in a rotatable state the attaching pointwise. One end and the other end of each support rod 5 are respectively jointed to each linear Fresnel lens 1 and each heat radiating plate 3 at positions where the lens 1 and the plate 3 intersect with the diagonal line of the parallelogram, which consists of the linear Fresnel lens 1, the heat radiating plate 3 and two rods of the support rods 4, and the support rod 5 is jointed to the linear Fresnel lens 1 and the heat radiating plate 3 in a rotatable state the attaching pointwise. This support rod 5 can be freely expanded and contracted and becomes the shortest length at the time of expansion of the folding focusing-type solar cell panel. The interval between each linear Fresnel lens 1 and each solar cell 2 is made to nearly equal to the focal length. |
