Referring to FIG. 1, a solar panel 200 using a translucent member may be disposed between the frames forming the roof surface of the greenhouse 10. As shown in FIG. 1, the roof surface on which the solar panel 200 is installed can be oriented toward the south, and the angle a of the roof surface forms an angle of 30 to 35 degrees from the ground surface that is substantially perpendicular to the incident angle of sunlight. So that it can be designed to be most effective for power generation of the solar cell 214.

The solar panel 200 may be fabricated to replace a translucent member surrounding a typical greenhouse 10 for cultivating crops. Referring to FIG. 2, the solar panel 200 includes a first substrate 212 for emitting light, a plurality of solar cells 214 disposed on the first substrate 212, An adhesive layer 216 disposed on the solar cell 214 and serving as a cushioning material and an adhesive for preventing breakage of the solar cell 214, for example, an ethylevinyl acetate (EVA) And a second substrate 218 that seals the first substrate 212 and the solar cell 214 by the first substrate 212 and the second substrate 218. The first substrate 212 and the second substrate 218 using the translucent member serve to fix the arrangement of the solar cell 214 and to transmit sunlight to help the photosynthesis of the crop in the greenhouse, It is intended to protect against weather and wind and rain. The translucent member may be made of glass, plastic, transparent metal, vinyl, or the like, but is not limited thereto and may be made of a transparent material.

The solar cell 214 can generate sunlight and block the sunlight at the same time. Accordingly, the first substrate 212 and the second substrate 212 are arranged at regular intervals so that sunlight can be incident on the solar cells 214. In an embodiment of the present invention, the spacing of the solar cells 214 is set to be between 7 and 8 cm, but the present invention is not limited thereto. It can be modified depending on the kind.

The database unit and the drive control unit can be controlled through a wireless network such as a smart phone.

The drive control unit may control a capacitor (not shown), an inverter (not shown) and the rail 300.

The controller may be electrically connected to the capacitor and the inverter, respectively, to control driving of the capacitor and the inverter. The photovoltaic cells 214 are generated by the incident sunlight to generate DC power and store the generated DC power in the capacitor. The DC power stored in the capacitor can be converted into AC power using the inverter and output. The capacitor and the inverter are disposed in an arbitrary position in the greenhouse 10 and are electrically connected to the solar cells 214. Accordingly, the control unit controls the capacitor to output the DC power, The inverter can be controlled to output the AC power.

The control unit is electrically connected to the rail 300 to control the movement of the wheel 320 of the rail 300 according to the amount of power stored in the capacitor or the type and the weather of the crop input to the control unit The position of the solar panels 200 can be controlled by controlling the amount of light incident on the greenhouse 10 and thus the amount of light incident on the greenhouse 10 can be adjusted.
