The present invention relates to an optimal inclination angle and azimuth angle selection notification system of a solar cell module, in detail, considering regional characteristics (dust concentration, regional temperature, regional solar radiation, airflow) and geographic requirements (pole location, power plant site availability) To provide an installation location selection system for a solar cell module that can calculate the optimal location of a solar power plant.

In general, the photovoltaic panel of the angle-controlled photovoltaic power plant is appropriately selected by selecting the fixing hole 14 formed in the adjusting unit 13 for adjusting the angle of the photovoltaic panel 11 as shown in FIG. By fixing the photovoltaic panel 11 to the supporting part 12,

By adjusting the orientation angle of the photovoltaic panel 11, it is configured to be able to manually manipulate the orientation angle of the photovoltaic panel 11 to any one of a plurality of different orientation angles fixed to have a constant unit interval. , it is known that when the angle of the photovoltaic panel 11 is adjusted at an appropriate time, the efficiency can be increased by about 5% compared to the fixed panel.

A photovoltaic power generation system as shown in FIG. 2 may be configured by using such an angle-controlled photovoltaic panel, and the photovoltaic system is electrically connected to a plurality of angle-controlled photovoltaic panels 1 . The connection panel 2 for providing the generated power provided from each angle-adjustable photovoltaic panel 1 to the grid connection unit 3, and the DC power output through the connection panel 2 into AC power and a grid connection unit 3 that converts and provides directly to the load, and a power storage unit 4 that stores some of the generated power and provides it for a specific purpose, wherein the grid connection unit 3, the power storage unit (4) and the connection panel (2) connected to the management to detect the amount of power generated according to the operation of each angle-controlled photovoltaic panel (1), detect an abnormality due to a decrease in output, and notify the manager It may include a server 5 .

The photovoltaic power plant is more preferred because it has the lowest location restrictions if it is an area where the sun shines, and it can be manufactured in a variety of shapes desired by operators from small facilities to large facilities.

However, the current location of the solar power plant is being installed without considering the electrical stability and geographical characteristics.

Future power systems should be selected with optimization criteria due to generational changes in power generation methods, but the current situation is not.

As a reference, prior art Patent Registration No. 10-814345 (applied on October 02, 2006) has a rotating operation unit that rotates the solar panel around a horizontal support so that the position of sunlight can be tracked, and the solar panel is moved up and down. A high-level operation part that rotates in the direction, and a rotation operation part

And there is disclosed a solar position tracking power generation device comprising a control driving unit for driving and controlling the altitude operation unit. With this structure, when the solar altitude changes according to the season, the rotation operation unit and the altitude operation unit can respond to the solar altitude change by varying the inclination angle of the solar panel.

However, in the prior art, the rotation operation part and the high operation part that rotate the solar panel have a complex structure such as a motor and a gear structure built-in, and a controller operated by electricity, so a lot of manufacturing cost was generated. .

In addition, since it is necessary to continuously install a plurality of solar location tracking power generation devices over a large area for large-capacity solar power generation, a lot of construction costs have been incurred, and these solar location tracking power generation devices There was a problem in that the structure in which the devices are interlocked is very complicated, and the maintenance cost of the facility is also high as a result.

Due to the above problem, as described above, the technology of the solar position tracking power generation device including an altitude operation unit for rotating the solar panel in the vertical direction, and a control driving unit for driving and controlling the rotation operation unit and the altitude operation unit is not used.

In other words, the technology that automatically adjusts the inclination and azimuth angles of solar panels is not economically viable and has been withdrawn from the market.

For this reason, the solar panel is mounted on a fixed structure whose inclination and azimuth angles are not adjusted.

When designing the structure, most of them set the angle of inclination and azimuth based on their own experience without precise data.

The present invention was devised in consideration of the above problems of the prior art, and the optimal location of a solar power plant in consideration of regional characteristics (dust concentration, regional temperature, regional solar insolation, airflow) and geographical requirements (jeon pole location, power plant site availability) It is a task to provide a system for selecting the installation location of a solar cell module that can calculate

The configuration will be described with reference to the accompanying drawings.

In the solar cell panel 10 for measuring the inclination angle and the azimuth angle that can set the inclination angle and the azimuth angle of a plurality of solar cell modules 50 that are installed on the entire site of the photovoltaic power plant 60 or are scheduled to be installed,

The solar cell panel 10 has a pole 11, and the bracket 12 is connected to the upper side of the pole 11,

There is a support frame 13 for supporting the solar cell panel 10 on the bracket 12, and a solar cell panel 10 is attached to the upper side of the support frame 13 in a plane, the support frame 13 and a hinge 14 connected to the connection part of the bracket 12 and the

Rotating the hinge 14 as the center so that the inclination angle of the solar cell panel 10 is variable,

The configuration will be described again with reference to the accompanying drawings and an embodiment thereof will be described as follows (see FIGS. 1, 2, 3 and 4).

The mini (for example, the size of about 300 mm in length and within 300 mm in width) of the present invention solar cell panel 10 is the solar cell panel 10 in advance before constructing the photovoltaic power plant 60 at the photovoltaic power plant site. to set the optimal position and optimal inclination and azimuth as shown below.

Thereafter, a plurality of solar cell modules 50 are constructed based on the set data.

In this way, the plurality of solar cell modules 50 may be constructed at various inclination angles and azimuth angles.

for reference here. Airflow and sunlight vary according to regions and places. However, since the conventional mini-solar cell panel 50 for measurement as in the present invention is not used, the inclination angle and azimuth angle of a plurality of solar cell modules 50 are uniformly constructed and have.

Therefore, conventional effective development cannot be expected.

In the configuration of the present invention, the solar cell panel 10 for measuring the inclination and azimuth angles capable of selecting the inclination and azimuth angles of a plurality of solar cell modules 50 that are installed on the entire site of the photovoltaic power plant 60 or are scheduled to be installed,

The solar cell panel 10 varies the solar cell panel 10 for measurement at a plurality of different inclinations or azimuth angles within a set time, and then makes them stay at different angles for a set time, and then the power collected at the different angles It is characterized by providing a system that monitors and notifies the optimal angle (inclination angle, azimuth) that produces the optimal power.

The azimuth angle refers to the rotation of the solar cell panel 10 with the support 11 as the center, and the inclination angle refers to the angle at which the solar cell panel 10 is inclined.

The solar cell panel 10 of the present invention has a pole 11, and a bracket 12 is connected to the upper side of the pole 11,

The bracket 12 has a support frame 13 for supporting the solar cell panel 10, and a solar cell panel 10 is attached to the upper side of the support frame 13 in a flat plane, the support frame 13 and the Connected to the connection part with the bracket (12) with a hinge (14),

Rotating the hinge 14 around the inclination angle of the solar cell panel 10, and

A hinge shaft 15 is connected to the connection portion between the bracket 12 and the support 11 so that the solar cell panel 10 has the hinge shaft 15 as a central axis of the solar cell panel 10 . It is configured to rotate in a plane that is an azimuth.

The hinge 14 may be a driving shaft of the first driving motor 20 , and the hinge shaft 15 may correspond to a driving shaft of the second driving motor 30 .

Therefore, when the first driving motor 20 is rotated by a preset program, the inclination angles of the bracket 12 and the solar cell panel 10 are varied.

And when the second driving motor 30 is rotated, the azimuth angle of the bracket 12 and the solar cell panel 10 is changed.

Furthermore, Figure 4 is an embodiment showing the state of monitoring the amount of power generated in a plurality of places by installing a plurality of the optimal inclination angle azimuth angle selection notification system of the photovoltaic power plant of the present invention in the photovoltaic power plant site (敷地) to be.

As described above, since the airflow or the amount of sunlight may be different in a plurality of places, after measuring the power generation output at each place, the inclination angle and the azimuth angle of the solar cell module may be different according to the characteristics of the terrain. This can be said to be the most effective development method.

In addition, in the case of monitoring the amount of power generated in multiple places by installing a plurality of solar power plants on all sides of the site (in various directions such as left and right with the center of the site as the center), the inclination angle and azimuth angle are varied according to the season. Thus, the optimal power production angle can be selected.

This applies to structures that can artificially modify the inclination and azimuth angles of solar cell modules already installed at the photovoltaic power plant site.

An example of the configuration is as follows (see FIG. 2).

First, the inclination angle of the solar cell panel 10 is made to be a plurality of inclination angles 10a.

For example, the first inclination angle 30 is 15 degrees and the amount of power generation is measured at 15 degrees for a set time, and then the second inclination angle 31 is 20 degrees and the power generation is measured at 20 degrees for a set time, , then the third inclination angle 32 is set to 30° and the amount of power generation is measured at 30° for a set time.

The following describes the azimuth (see Fig. 3).

The azimuth angle 40 of the solar cell panel 10 is made to be a plurality of azimuth angles.

It means that the solar cell panel 10 rotates in a state in which the solar cell panel 10 faces the sky with the hinge axis 15 as the central axis at the inclination angle of the solar cell panel 10 .

For example, after rotating the solar cell panel 10 by 15° in the state where the solar cell panel 10 is stopped, the amount of power generation is measured for a set time in the 15° state, and then rotated to 20° and then rotated at 20° Measure the amount of power generation during the set time and then rotate it by 30° to measure the amount of power generated during the set time in that state.

In such a sequence, a plurality of inclination angles 10a and azimuth angles 40 are sequentially measured, and power production is sequentially measured at the inclination angles and azimuth angles.

As shown in FIG. 5 by measuring as described above, the inclination angle and the azimuth angle of a plurality of solar cell modules are selected at the photovoltaic power plant site.

The generation amount measurement as described above can be measured by a user directly at the site of the photovoltaic power plant site, if necessary, and can be measured by interlocking with a monitoring device installed inside the connection panel with a connection panel to be described later. .

In contrast, the Hall element or the fuse element may be used to measure the current by being installed on the cable leading from the solar cell panel to the connection panel and the inverter.

The communication unit may collect and transmit current data measured by the current measurement unit. The communication unit may be installed inside the housing housing the junction panel, and the current data measured by the current measurement unit installed on the junction panel and cable leading into the housing may be collected and transmitted to the monitoring unit.

The solar cell panel 10 is a configuration for cleaning the surface of the solar cell panel 10 by operating the brush 41 by the third driving motor 40, and the embodiment will be described in detail later. The configuration to be described later is filed on the same date as the patent application of the present invention as another configuration and embodiment.

Looking at the following configuration, (refer to Figures 7 and 8)

a current sensor unit for detecting a cable entering the inverter from a plurality of solar cell modules 100, a communication unit 320 for collecting and transmitting current data measured by the current sensor unit 310;

In the solar power generation system monitoring device comprising a monitoring unit 400 for determining whether one of the solar cell array 100, the connection panel 200 and the inverter 300 is abnormal,

The solar cell module 100 outputs a DC current and provides it to the connection panel 200, but is connected to the driving unit of the driving motor 500 at a position close to the solar cell module 100 and moves according to the movement of the driving unit. By installing 520

The amount of power generated by the first solar cell panel 100a cleaned through the brush 520 and the amount of power detected through the sensing unit h

The amount of power generated by the second solar cell panel 100b that is not cleaned is compared with the amount of power detected through the sensing unit h.

If there is a difference more than the standard value, the monitoring unit monitors the entire plane of the solar cell module 100, but

The driving motor 500 is connected to the driving motor 500 and the battery 500a by a circuit 500b so as to receive power from the battery 500a.

The driving motor 500 is controlled according to a signal from the control unit 500d, and the control unit 500d is connected to the raindrop sensor 500e for detecting rain water.

When rain is detected through the rain drop sensor 500e and the control unit 500d, the control unit 500d supplies power from the battery 500a to the driving motor 500 through the circuit 500b to supply the driving motor 500 ), the first brush 520 in close contact with the surface of the solar cell panel 100a moves according to the operation of the solar cell panel 100a to monitor the configuration for cleaning the surface of the solar cell panel 100a.

The driving part of the driving motor 500 and one side of the brush 520 are connected, and the other side of the brush 520 is in close contact with the surface of the solar cell panel 100a.

Therefore, when the forward and reverse rotations of the driving motor are repeated, the brush reciprocates left and right to clean the surface of the solar cell panel 100a.

When the driving motor 500 rotates, the brush 520 may also rotate to clean the surface of the solar cell panel 100a.

The surface of the solar cell panel can be cleaned by moving the brush in various ways with the rotational force of the driving motor 500 .

A driving motor 500 is installed on one side of the solar cell panel 100a.

and install the brush 520 on the driving part 510 of the driving motor 500,

The driving motor 500 is connected to the driving motor 500 and the battery 500a by a circuit 500b so as to receive power from the battery 500a.

The circuit 500b is connected to a switch 500c to turn on/off the power flowing through the circuit 500b, the switch 500c is controlled according to a signal from the controller 500d, and the controller 500d is the humidity. In a state provided with a rain drop sensor (500e) for detecting and a temperature sensor (500f) for detecting the external temperature

When rain is sensed through the rain drop sensor 500e, the control unit 500d supplies power from the battery 500a to the driving motor 500 through the circuit 500b to drive the brush according to the driving of the driving motor 500. 520 is moved to clean the surface of the first solar cell panel 100a

When the external temperature is detected through the temperature sensor 500f and the control unit 500d and the detection result is above the preset temperature, the driving motor 500, the brush and the first solar cell panel 100a are not frozen. and turn on/off the switch 500c so that the power of the battery 500a flows to the driving motor 500

When the external temperature is detected through the temperature sensor 500f and the control unit 500d and the detection result is below the preset temperature, it is determined that the drive motor 500 brush and the first solar cell module 100a are frozen. It is configured to turn off/off the switch 500c so that the power of the battery 500a flows to the driving motor 500 .

The set temperature is the temperature at which the winter temperature freezes the surroundings is less than the set temperature

The ambient temperature without freezing is higher than the set temperature.

The reason for doing this is to prevent the driving motor from operating when the operating parts such as the driving motor are frozen when the temperature is lower than the set temperature in winter.

In particular, when heavy snow falls below the set temperature, snow accumulates and freezes on the surface of the solar cell panel 100a, but the brush cannot sweep away the frozen snow. When the driving motor 500 operates in that state, the driving motor overheats could lead to a topic of discussion.

However, even if it snows in winter, if the temperature is higher than the set temperature, the falling snow continuously melts and flows down from the surface of the first solar cell module.

The drive motor is not loaded.

The raindrop sensor is a sensor that detects rain or snow, and the technology related to this raindrop sensor includes a stand-alone raindrop sensor of Registration No. 20-0370408, Publication No. 2003-0005887,

Please refer to Publication No. 10-2017-0070533.

A diode may be installed. A plurality of connection panels may be connected to one inverter.

The inverter 300 may convert the generated power provided in the form of direct current from the connection panel 200 into alternating current and supply it to a load terminal (not shown). The inverter 300 is installed inside the electrical room, and each inverter 300 is connected to a plurality of connection boards 200 and cables to receive DC power.

8 and 9 are block diagrams of a solar power generation system monitoring apparatus according to an embodiment of the present invention.

Referring to FIGS. 8 and 9 , the monitoring device of a solar power plant according to an embodiment of the present invention includes a current sensor unit 310 installed in a cable 301 leading into an inverter 300 , an inverter box or a junction box inside. It may be configured to include a communication unit 320 for performing data communication and a monitoring unit 400 for receiving current data from the communication unit 320 to monitor the solar power plant.

First, the current sensor unit 310 may be installed for each cable 301 introduced from the solar power plant connection panel to the inverter 300 . The current sensor unit 310 may be, for example, a ring-shaped current transformer installed on each of the cables 301 introduced into the inverter 300 . The current sensor unit 310 may measure a current for each cable 301 introduced into the inverter 300 and transmit current data to the communication unit 320 . Unlike this, it is installed in each of the cables 301 introduced into the inverter 300 using a Hall element or a fuse element to measure the current.

The communication unit 320 may collect and transmit current data measured by the current sensor unit 310 . The communication unit 320 may be installed inside the housing accommodating the inverter 300 and the current sensor unit 310 installed in the cable 301 connecting the connection board 200 and the inverter 300 leading into the housing. The current data measured by the may be collected and transmitted to the monitoring unit 400 .

The monitoring unit 400 classifies the current data received from the communication unit 320 according to the junction panel 200 that is received for each inverter 300, and compares the junction panel current data for each inverter with each other to connect the solar cell array, It can be determined whether at least one of the half and the inverter is abnormal.

In addition, the monitoring unit 400 may be configured to further include a display device that displays data classified according to the connection panel introduced for each inverter 300 .

The monitoring unit 400 may be installed inside an electrical room accommodating a plurality of inverters or implemented in a management room or a situation room outside the electrical room.

That is, the monitoring unit 400 may receive current data from a plurality of inverters or electrical rooms and use them to determine whether the entire solar power generation system is abnormal or whether individual abnormalities are present, and transmits the situation information to the outside through the display device. can be displayed

The motoring unit 400 may determine that an abnormality has occurred in the connection panel when the current data of the connection panel connected to the specific inverter is out of a preset ratio range. That is, when the current data of the connection panel greatly deviates from the absolute value, the monitoring unit 400 may determine that an abnormality has occurred in the corresponding connection panel without comparison with the current data of the other connection panel. When an abnormality occurs in a connection panel, the current data of the entire solar cell array connected to the connection panel appears to be out of a normal value, so it is possible to determine whether there is an abnormality using the current data of the connection panel without comparing each other. For example, the monitoring unit 400 may determine that an abnormality has occurred in the corresponding connection panel when it is out of the range of 90% compared to the current value during normal operation, and the ratio range may be changed by setting.

Also, the monitoring unit 400 may determine that an abnormality has occurred in the corresponding inverter when all of the current data of the connection panel connected to the specific inverter is out of a preset ratio range. That is, the monitoring unit 400 may determine that an abnormality has occurred in the corresponding inverter when all the current data of the plurality of connection panels connected to the individual inverters are out of normal values.
