PURPOSE: A sunlight tracking sensor unit is provided to improve sunlight tracking precision and increase collection efficiency by reducing the width of an opening for inducing sunlight inside. CONSTITUTION: A sunlight tracking sensor unit comprises a body(110), a large light-guiding part, a small range light-guiding part, a photo-electro transform part(160), a drive part(170), and a controller(180). The body has a main body(112), and a light incidence guide pipe part(114). The light incidence guide pipe part is expanded upward. The sunlight is incident to the inside of the light incidence guide pipe part. The large light-guiding part is installed in the main body along the columnar direction and receives sunlight. The large light-guiding part comprises multiple optical fibers. The small range light-guiding part guides the guided light income through the opening of the light incidence guide pipe part. The drive part rotates the body in the first direction and the second direction. The controller rotates the body through the drive part. |
