In this case, the first support unit 120 coupled to one end of the transfer member 303 is adjusted to an altitude angle of the solar cell module 10 together with the support frame 110 at a position of the sun. Control of the elevation angle is made.

And, as shown in Figure 2, the main body 300 is the first drive motor (M1) and so as to adjust the azimuth and altitude angle of the solar cell module 10 according to the movement trajectory of the sun over time It includes a control unit 500 for controlling the second driving motor (M2), respectively.

FIG. 5 is a block diagram schematically showing the configuration of the controller 500 shown in FIG. 2.

As shown in FIG. 5, the control unit 500 is composed of a GPS module 510, a communication module 520, a weather module 530, and a control module 540, and the first and second driving motors. By controlling the altitude and azimuth angle of the solar cell modules (10).

Here, the meteorological module 531 receives the information obtained from the communication module 520 or the GPS module 510 to receive the yellow dust mode 531, the typhoon mode 532, the snow cover mode 533, and the monsoon mode 534. ) Is transmitted to the control module 540.

The yellow sand mode 531 after the end of the power generation in preparation for the yellow dust dust in Mongolia between March and May, so that the direction of the solar cell module 10 toward the southeast direction of the opposite direction from which yellow sand is flying.

That is, when dust of yellow dust generated in Mongolia is deposited on the surface of the solar cell module 10, the power generation efficiency decreases by that amount. By being located in the opposite direction to the coming direction it can be prevented before the yellow sand is settled on the surface of the solar cell module 10.

The typhoon mode 532 according to the meteorological office data for the last 100 years, 90% of the typhoons that affect our country is from July to September, so that the impact of the wind pressure during the typhoon most occur during the period of the solar cell The module 10 is controlled to be horizontal to the ground to wait.

That is, when typhoons or strong winds blow, the typhoon or wind strength information may be previously obtained from the GPS module 510 or the communication module 520 in order to minimize the damage of the photovoltaic device 100 according to the present invention. The receiving typhoon mode 532 analyzes it and transmits it to the control module 540, and the control module 540 moves the first driving motor and the second driving motor so that the solar cell modules 10 face the sky. By controlling it, the damage from typhoons and winds can be minimized.

The snow mode 533 receives information on snow from the GPS module 510 or the communication module 520 in advance, analyzes the snow information, and transmits the snow information to the control module 540, and the control module 540 is configured to receive the snow information. The solar cell modules 10 may be controlled to be perpendicular to the ground to minimize damage from the eyes.

That is, when snow accumulates on the surface of the solar cell modules 10 due to the snow, the main body 300 may be deformed or damaged by the load of the eye, including the support frame 110 supporting the solar cell modules 10. If there is a risk of receiving weather information that is snowing or snowing in real time, the snow mode 533 is determined and transmitted to the control module 540, the control module 540 is the first drive motor And controlling the second driving motor so that the solar cell modules 10 are perpendicular to the ground.

The monsoon mode 534 is a season in which the summer starts in June, and the inland temperature is higher than the ocean temperature in consideration of the characteristics of the monsoon blowing from the sea to the land. The west side should face west. In addition, in October-December, considering that the inland temperature is lower than the ocean temperature, the solar wind modules 10 may be least affected by the wind, considering the characteristics of the monsoon winds that blow from the northwest Siberia. Facing the direction of the whipwind.

In addition, considering the dew in fall or the sister in the winter season, if the dew or snow accumulates on the upper surface of the module, it affects power generation, so that the inclination angles of the solar battery modules 10 2 drive motor.

Here, the monsoon means that the ocean heat capacity is larger than that of the continent, so the continent warms quickly and cools quickly. Therefore, in summer, the continents have a higher temperature than the ocean and become a low pressure part, and in winter, the temperature becomes a high pressure part, so the wind blows from the ocean to the inland in the summer and from the inland to the ocean in the winter.

Accordingly, in the seasonal wind mode 534, the direction of the solar cell modules 10 is controlled according to the seasonal wind by controlling the drive motor M to be optimal to prevent damage to the solar cell generator.

The photovoltaic device 100 according to the present invention as described above is the direction of the solar cell modules 10 according to the weather information through the controller 500 programmed separately to control the first drive motor and the second drive motor. Control to the optimum direction.

Previously, trekkers could only control the trekkers in the controller and monitoring program. However, when the solar installation capacity was large, the trekkers could not be controlled by the monitoring program. Although it was possible to control only where it is installed, it is possible to control the azimuth and altitude angles of the solar cell modules 10 freely through typhoon mode, yellow dust mode, snow cover mode, and monsoon mode to improve power generation efficiency and damage damage. You can prevent it.

Here, the GPS module 510 receives a GPS signal from a satellite, that is, acquires weather information such as temperature, humidity, and wind, and transmits the weather information to the controller 540 through the weather module 530, and further, the GPS signal. The module 510 notifies the location where the photovoltaic device 100 is installed and at the same time knows the current time.

The communication module 520 generates about 15 photovoltaic devices into one group by using RS 485 communication, simultaneously receives detection signals of each photovoltaic device and transmits them to the control module 540 to transmit each photovoltaic power generation. Control the device the same. Meanwhile, group control may be performed for each group.

Hereinafter, with reference to the drawings will be described in detail the operational effects of the photovoltaic device 100 according to the present invention.

6 to 8 are side views illustrating that the arrangement angle of the solar cell module 10 shown in FIG. 1 changes according to the altitude change of the sun. Like reference numerals denoted below denote like components.

The straight line L connecting the surface of the solar cell module 10 from the sun should be in a vertical state to maximize the light collecting efficiency.

As shown in FIG. 6, the altitude h1 of the sun at the sunrise is maintained at the lowest state. In this case, the arrangement angle θ1 of the solar cell module 10 should be the largest inclination angle from the ground.

To this end, one end of the transfer member (see FIG. 4, 303) should be drawn out to push up the first support unit (see FIG. 1, 120) as much as possible.

In this case, since the transfer member 303 is discharged upwardly from the vertical driving part 300, the arrangement angle of the solar cell module 10 is the largest inclination angle.

At this time, the direction toward which the solar cell module 10 is directed should be the east direction where sunrise begins.

As shown in FIG. 7, as time passes, the sun moves from east to southeast, and accordingly the altitude h2 is also increased.

Reflecting the direction and altitude change of the sun, when the controller (see FIG. 2, 500) controls the first driving motor M1, the solar cell module is rotated by the rotation of the first driving motor M1. (10) rotates to look southeast.

On the other hand, the conveying member 303 pulls the first support unit 120 to raise the height (h2) of the support frame together.

When the transfer member 303 is pulled, the upper end of the solar cell module 10 is flipped backward, and the arrangement angle θ2 is smaller than the ground in FIG. 6.

As shown in FIG. 8, as time elapses and the sun reaches the highest altitude h3, the sun is located south.

At this time, the solar cell module 10 is rotated to face south by the first driving motor (M1), one end of the transfer member 303 is pulled up to the first support unit 120 to the maximum support The angle of the frame 110 is made to be almost the same angle as the ground.

In this case, since the first support unit 120 coupled to one end of the transfer member 303 is pulled downward to the maximum, the inclination angle of the solar cell module 10 is the smallest.

Therefore, the arrangement angle θ3 of the solar cell module 10 may maximize the light collection efficiency by forming the smallest inclination angle.

As time passes, the sun moves in the southwest direction, and the altitude of the solar cell module 10 is also lowered. Accordingly, the first driving motor M1 causes the solar cell module 10 to move southwest. Rotate to face

And, reflecting the lowered altitude, the height of the first support unit 120 in which one end of the transfer member 303 is engaged is also raised to achieve a larger inclination angle.

As the sunset approaches, the sun is on the west side, and the altitude of the solar cell module 10 is also lower.

Reflecting this, the first driving motor M1 performs a rotational movement so that the solar cell module 10 faces the west direction.

In addition, one end of the transfer member 303 is located at a portion of which the height of the first support unit 120 is lowest, in consideration of the solar altitude of the state.

Therefore, the arrangement angle of the solar cell module 10 forms a maximum inclination angle. And after the sun is set after sunset, the solar cell module 10 is rotated to face the east direction before the start of the next sunrise so that the solar cell module 10 can focus again at the next sunrise.

Therefore, the photovoltaic device 100 according to the present invention automatically rotates to maximize the condensing efficiency according to the change in the altitude of the sun and the change in the azimuth angle of the sun over time, and also according to the change of the season. In response to the change in the altitude of the sun, it is possible to adjust the altitude and azimuth angle according to time and season.

In addition, through the control unit 500 is expected to more effectively control the altitude and azimuth angle corresponding to the position of the sun.
