In addition, according to the present invention, the plurality of solar panels 10 are arranged spaced apart by a predetermined distance (refer to the reference numeral e in Fig. 3) on the facility structure in order to secure sunlight necessary for the growth of crops. Can be.

In addition, each of the plurality of solar panels 10 includes a light-transmitting base member; And a plurality of photoelectric conversion cells disposed on the light-transmitting base member in an N*M matrix form (a 9*4 matrix form is exemplified in FIGS. 3 to 5). By including, between the plurality of photoelectric conversion cells A light-transmitting area through which light is transmitted through the light-transmitting base member and a light-shielding area in which light is shielded by the plurality of photoelectric conversion cells, corresponding to a predetermined space (see reference numeral f in FIG. 4) formed in It can be built to exist. In this way, when a system using a transmissive module through which a certain amount of light is transmitted by securing the separation distance between solar cells connected in series inside the module, additional light for utilization of the space under the facility can be secured when operating the solar power generation system. There is also an effect that can be [see Fig. 4].

At this time, the number of solar panels 10 installed is a light shielding area by a plurality of photoelectric conversion cells in the plurality of solar panels 10 compared to the area of the planting area in which the crop will be planted in the crop cultivation area. The ratio of the area occupied may be determined by the maximum number of panels that can be installed within a range that does not exceed the maximum allowable shading rate, based on the light saturation point of the crop to be planted.

In general, the rate of photosynthesis in plants is proportional to the intensity of light, but the rate does not increase when the light saturation point is reached. Therefore, the light saturation point is different depending on the type of crop, and the strong light of 70~80klux is the light saturation point for watermelon and tomato, and the medium light of 40~45klux for cucumbers, pumpkins, cabbage, and peas is the light saturation point. On the other hand, lettuce and sweet potatoes have a weak light saturation point of about 25klux. Therefore, if the distance between the solar panel and the solar cell module of the panel (i.e., photoelectric conversion cell) is adjusted in consideration of the shading rate that does not affect the growth of the solar structure depending on the target crop, agricultural production will be hindered. It is possible not to receive it. In 2017, Korea South-East Power reported the empirical result that the difference in the yield between the site where the photovoltaic power generation was conducted and the control site that did not have a solar power generation was 5% as a result of the first demonstration of solar power generation in parallel with rice farming in Korea. In this regard, FIG. 6 is a schematic diagram of the appropriate shading rate design value of the solar structure considering the light saturation point for each crop, and the crop to be planted by using the tabled data of the relationship between the light saturation point and shading rate design value for each crop. Each shading rate can be properly designed.

In addition, according to the embodiment of the present invention, the solar power generation system that performs the function of the fruit tree crop cultivation house can be used as a structurally stable fixed solar power generation system in normal times, and the southern middle altitude of the sun according to seasonal changes When the azimuth of the module needs to be changed according to the change or change of the installation location, it can be designed as a structure capable of changing the angle of the upper solar cell even when the system is installed according to the ridge direction of the fruit crop being cultivated.

To this end, it may include an angle change unit 50 for changing the installation angle of the solar panel 10. In this case, the angle changing unit 50 includes an azimuth changing means for changing the azimuth angle in the horizontal direction while maintaining the inclination angle of the light incident surface of the solar panel 10 as it is, and the solar panel 10 It may include an elevation angle changing means for changing an elevation angle in a vertical direction to change an inclination angle of the light incident surface, and a driving actuator providing a driving force to the azimuth angle changing means and the elevation angle changing means. 9 and 10 do not present a clear structure with respect to the configuration of the angle changing unit 50, but the above-described elevation angle changing means/azimuth angle changing means and driving actuator are parts that can be sufficiently designed and applied even with known technical means. In bar, those skilled in the art will be able to easily understand and infer the structure.

In addition, the solar power generation system performing the fruit tree crop cultivation house function of the present invention includes a control unit for controlling the operation of the driving actuator to perform at least one of a change in an azimuth angle and an elevation angle of the solar panel 10 to be executed; Can include.

In addition, according to an embodiment of the present invention, the facility structure includes an illuminance sensor, an insolation sensor, and a carbon dioxide measurement sensor; A temperature sensor, a humidity sensor, a soil temperature/humidity sensor, an electrical conductivity sensor, etc. may be installed, and various operation controls may be performed based on a sensing result accordingly (see FIG. 7 ).

For example, when the light intensity measured according to the sensing result of the illuminance sensor is out of the range of the planned insolation value for the crop, the controller generates a control command for changing the elevation angle of the solar panel 10 By transmitting to the driving actuator, the size of the shadow area generated by the solar panel 10 as a ratio of the area occupied by the light shielding area can be changed (see FIG. 8).

As another example, when the light intensity measured according to the sensing result of the illuminance sensor has a value lower than the light saturation point of the crop, the control unit generates a control command to increase the elevation angle of the solar panel 10 By transmitting to the driving actuator, the area ratio occupied by the light shielding area may be reduced. In addition, the control unit generates a control command for changing the azimuth angle of the solar panel 10 only when the light intensity measured according to the sensing result of the illuminance sensor has a value higher than the light saturation point of the crop. Control command for changing the elevation angle of the solar panel 10 while allowing the light incidence surface of the solar panel 10 to track the moving position of the sun according to the change of time by day by transmitting it to the driving actuator Can be generated and transmitted to the drive actuator to track changes in altitude of the sun.

As another example, the control unit may issue a control command for changing the azimuth angle of the solar panel 10 when the humidity value measured according to the sensing result of the humidity sensor reaches the humidity value pre-scheduled for the crop. By generating and transmitting it to the driving actuator, it is possible to change the size of the shadow area generated by the solar panel 10 according to the change of time per day.

According to the solar power generation system that performs the function of the fruit tree crop cultivation house according to the above, it is possible to perform solar power generation and farming activities of fruit tree crops at the same time, and to install a photovoltaic power generation device, a large scale in the forest field. Not only does it not destroy the environment such as civil engineering works, but also does not destroy agricultural land, it has the effect of providing the structure, shape, and function of the solar power generation system that functions as a fruit crop cultivation house that improves the amount of solar power generation. have. In addition, it is possible to simultaneously operate solar power generation and farming activities of fruit tree crops at low cost, and it is possible to construct an economical system by not installing a separate solar cell module holder for parallel development of agriculture, but also functioning as an existing crop rain cover house. It is possible, and it is easy to maximize the amount of power generation through a structure capable of varying the angle of the solar panel even if the crops of the existing orchard are not facing south.

The above has been described with reference to the embodiments of the present invention, but those of ordinary skill in the relevant technical field variously modify the present invention within the scope not departing from the spirit and scope of the present invention described in the following claims. And it will be easily understood that it can be changed.
