When the PV module louver 60 is installed between the two brackets 20, the pivot shaft 22 of the bracket 20 is inserted into the insertion hole of the vertical frame 12, The electric wire 62 of the louver 60 is passed through the protective cap 61 and then passed through the through hole 23 at the center of the pivot shaft 22. [

Referring to FIG. 3, the angle adjusting portion includes a fixing plate 30, a rod bar 40, a turning cap 50, and the like. The angle adjuster mechanically couples to the end of the solar power generator louver 60 to adjust the angle.

The fixing plate 30 is fixed to the window frame to support the solar photovoltaic louvers 60 so as to be rotatable. The fixing plate 30 is formed in a bar shape having a predetermined length in the vertical direction and has through holes 31 formed at regular intervals to receive the pivot shaft 22 of the bracket 20 described above.

Referring to FIG. 7A, the solar sensor 90 according to the present invention is provided in a predetermined space Sp1 at one point of the horizontal frame 11. As shown in FIG. The space Sp1 is formed as a space enlarged toward the front so as to receive the sunlight in a state without indirect sunlight and is formed at a position protruding from the wall so as not to be covered by a wall or the like.

The solar sensor 90 includes at least two unit solar photovoltaic modules 91a, 91b, and 91c that are perpendicular to each other. The unit solar photovoltaic module according to the present embodiment includes a total of three units: the first unit solar photovoltaic module 91a, the second unit solar photovoltaic module 91b, and the third unit solar photovoltaic module 91c . The first unit solar photovoltaic module 91a is provided parallel to the horizontal plane, and the second unit solar photovoltaic module 91b and the third unit solar photovoltaic module 91c are installed in a vertically erected state. At this time, the first unit solar photovoltaic module 91a, the second unit solar photovoltaic module 91b and the third unit solar photovoltaic module 91c are provided so as to form right angles, respectively, It is preferable to be able to perform the measurement.

As shown in FIG. 7 (b), each of the unit solar photovoltaic modules 91a, 91b ', and 91c' may be provided to have the same surface area. However, as shown in FIG. 7 (a) It is possible to calculate the altitude position related data of the sun for adjusting the angle of the solar power generating louver to be described later by calculating the current amount per unit area.

8, the current collected through the solar sensor 90 is measured by the current amount measuring unit 910 for each unit of the individual solar power generation modules, and the sun position calculating unit 920 or Is used as basic data for calculating the position of the sun by the louver control unit 930 or for adjusting the angle of the solar power generating louver.

Specifically, the current amount measuring unit 910 measures the amount of current generated from each of the unit solar photovoltaic modules 91a, 91b, and 91c, and transmits the measured current amount to the sun position calculating unit 920 or the louver controlling unit 930.

The sun position calculating unit 920 calculates the vertical component per unit area and the horizontal component per unit area of the amount of current from the amount of current of the first to third unit solar photovoltaic modules 91a, 91b, 91c measured by the current amount measuring unit 910 And provides the louver control unit 930 with the altitude of the sun.

7, assuming that the shape of the first unit solar photovoltaic module 91a is a right-angled isosceles triangle, and the length of the adjacent equilateral sides is La, each of the first through third unit solar battery modules 91a, The horizontal component per unit area of the total current is equal to the amount of current per unit area 2 [1] of the first unit solar battery module 91a when the currents measured from the first unit solar battery modules 91a, 91b, 91c are respectively [I1], [ I1] / La ²⁾ per unit area, the vertical component of this is, the total current can be calculated by synthesizing the amount of current of the second unit photovoltaic module (91b) and the third unit of PV modules (91c). In other words, per unit area, the vertical component is a ([I2] + [I3] ) / (2 La 2).

A relatively large horizontal component means that the altitude of the sun is high, and a large vertical component means that the altitude of the sun is low. In addition, the direction of the sunlight, the position of the sun, the intensity of the sunlight, and the like can be calculated by calculating a vector having the vertical component and the horizontal component as factors. The intensity of sunlight can be calculated through the absolute value of the corresponding vector.

The louver control unit 930 calculates the altitude of the sun from the current amount ratio and current amount of the unit solar photovoltaic modules 91a, 91b and 91c or receives the data from the sun position calculation unit 920, So that the rotation angle of the photovoltaic louver 60 can be adjusted to achieve the optimum power generation efficiency.

Specifically, the louver control unit 930 may have a power generation amount table per unit area estimated according to the calculated altitude of the sun. The power generation amount table may be provided with a vector or a vector component as an estimated power generation amount according to the sun altitude at the position where the louver window is installed. Such estimated power generation amount data can be used for predicting the outside environment such as clouds, calculating the intensity of the reflected light instead of direct light, or determining the lifetime or performance of the unit photovoltaic generation module through comparison with the calculated vector value have.

For example, an absolute value of a vector having a vertical component per unit area and a horizontal component per unit area may be calculated and then compared with the power generation amount table to determine whether or not the optimum angle control of the solar photovoltaic louver is possible. If the power generation efficiency is lower than the predetermined reference efficiency through the comparison, the control for the efficiency of the solar power generation is abandoned, and the humidity or temperature measurement unit 970, which is measured through the humidity measurement unit 960, It is also possible to control it according to the conventional method based on the temperature measured by the temperature sensor.

On the other hand, the azimuth angle of the sun, that is, the position in the horizontal plane, can be calculated by comparing the amount of current measured from the second unit solar photovoltaic module 91b and the third unit solar photovoltaic module 91c. The azimuth data and the current vector values are accumulated and calculated every day, so that it is possible to predict the location of the date, time, and louver window even in an environment where there is no separate network.

In the case of the louver control unit 930, when the outside air humidity measured by the humidity measuring unit 960 is equal to or higher than a certain standard, the solar control louver is closed or the inside air temperature is compared with a predetermined desired temperature, The control for determining whether the louver is open or closed can be performed in parallel with the control for the optimum efficiency of the photovoltaic power generation. In addition, data on the operating state of the air conditioner corresponding to the position of the louver window can be received, and when the air conditioner is in operation, control for optimal efficiency of the solar power generation can be performed in a state in which the solar power louver is opened .
