SUNLIGHT ORIENTED SOLAR CELL PLATE CONTROL METHOD

摘要

PURPOSE: A method for controlling a sunlight oriented solar cell plate is provided to improve the efficiency of the solar cell plate by positioning the solar cell plate to be perpendicular to sunlight regardless of the season or duration of sunshine. CONSTITUTION: A plurality of optical sensors(3) symmetrically installed with respect to the post(2) on a solar cell plate(1) receives the sunlight. Each of the outputs from the sensors(3) is compared with each other. The outputs are calculated with a calibrating value being an amount of the inclination to two vertical axes perpendicular to the sunlight. The solar cell plate(1) is inclined to be perpendicular to the sunlight according to the calibrating value.
