Claim:
1. A photovoltaic blind system, comprising: a plurality of blind slats configured such that photovoltaic panels are attached thereto, respectively; a power amount measurement unit configured to measure power amounts generated by the photovoltaic panels; an apparatus for hybrid solar tracking; and a drive unit configured to control directions of the blind slats according to directions of the photovoltaic panels determined by the apparatus for hybrid solar tracking; wherein the apparatus for hybrid solar tracking comprises: a first power output prediction unit configured to generate first predicted power output data by analyzing first measured power output data of the past through time series analysis; a second power output prediction unit configured to obtain a lagged error between the first measured power output data and the first predicted power output data, to construct an RA model for predicting second predicted power output data based on the first measured power output data, the first predicted power output data and the lagged error, and to derive the second predicted power output data; a third power output prediction unit configured to construct an ANN model for predicting third predicted power output data according to the following equation to derive the third predicted power output data: where {circumflex over (Z)} a solar tracking control unit configured to select either a method for solar tracking based on photovoltaic power output or a method for solar tracking based on location and time, depending on whether the second measured power output data of the present time falls within a filtering range based on a first error range of the second predicted power output data and a second error range of the third predicted power output data, and to determine the directions of photovoltaic panels according to the selected method for solar tracking, wherein the drive unit is operable to: control vertical directions of the photovoltaic panels on the blind slats by controlling angles of the blind slats in such a way as to wind or unwind ropes for the control of angles using wire pullers and motors according to the determined directions of the photovoltaic panels; and control horizontal directions of the photovoltaic panels on the blind slats hung from a housing including the drive unit and the apparatus for hybrid solar tracking by rotating the housing connected to a window frame in such a way as to drive gears, fastened to the housing and the window frame, respectively, using a motor.
