PURPOSE:To make solar energy collection of high efficiency possible, by a method wherein a columnar lens whose cross section is a right triangle is mounted on the surface of a solar in the manner in which the light receiving surface can turn up and down according to the position of the sun, and horizontal rotation is performed once a day so as to track the sun. CONSTITUTION:A columnar lens whose cross section is a right triangle is mounted on the surface of a solar, in the manner in which the solar ray with a low incidence angle is subject to a total reflection in order to make an incidence into the solar vertically or almost vertically. An equipment is provided which retains the above lens and makes the light receiving surface turn up and down according to the position of the sun. The equipment performs horizontal disc-type rotation once a day, and further it is provided with an equipment to remove snow and an equipment to remove dust. For example, a bag-type sheet is put on the solar, and an assembly of the lens and a frame is mounted theron. When a liquid in the bag is discharged, one surface which pinches a shaft as a supporting point reses up vertically. When the sun reses over a certain angle, the bag is made full of liaued to make the inclined surface of the lens turn upward. |
