Description

Solar panel backup system and method thereof

The present invention relates to a backup system and method thereof, in particular to a solar panel backup system and method thereof.

In recent years, with the rise of environmental awareness, how to obtain electricity in a more environmentally friendly way has become one of the problems that manufacturers are eager to solve.

Generally speaking, traditional green energy generation includes: solar energy, hydropower, wind power, tidal energy, geothermal energy, etc. Among them, solar power generation is the most common and popular. However, solar panels are easily damaged by factors such as typhoons, flying sand and rocks, which in turn affects the efficiency of photovoltaic conversion. When damage actually occurs, it is impossible to provide maintenance in time, so there is a problem of poor timeliness of maintenance of solar panel devices.

In view of this, some manufacturers have proposed a technical means of integrating sensors to determine whether the solar panel is damaged by real-time sensing of its operating status. If so, the maintenance personnel will be notified to replace it. However, this method still has a long window period from notifying the maintenance personnel to the actual completion of the maintenance, so it still cannot effectively solve the problem of poor timeliness of maintenance of solar panel devices.

In summary, it can be seen that the maintenance timeliness of solar panel installations has long been a problem in previous technologies, so it is necessary to propose improved technical means to solve this problem.

The following will be used in conjunction with diagrams and examples to explain in detail the implementation of the present invention, so that the process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

Please refer to "Figure 1" first. "Figure 1" is a system block diagram of the solar panel backup system of the present invention. The system includes: a remote device 110 and a double-sided solar panel device 120. The remote device 110 is used to receive a warning signal containing a unique identification code. In actual implementation, each solar panel has a unique identification code. The unique identification code contained in the warning signal represents the unique identification code of the damaged solar panel. The damaged solar panel can be known by the unique identification code.

The bifacial solar panel device 120 has a frame, a rotating shaft is passed through the horizontal center line of the frame, and solar panels with unique identification codes are respectively arranged on opposite sides of the frame. The bifacial solar panel device 120 includes: a sensor module 121, a drive module 122 and a communication module 123. Among them, the sensor module 121 is used to set a plurality of sensors on the solar panel, and continuously sense the ratio of the normal operation quantity and the abnormal quantity of the sensor to calculate the integrity of the solar panel, and record the unique identification code of the abnormal solar panel. In actual implementation, the sensed normal operation quantity and the abnormal quantity are negatively correlated, and the higher the abnormal quantity, the lower the integrity. For example, when the number of anomalies is 60%, the integrity is 40%; when the number of anomalies is 80%, the integrity is 20%, and so on. In addition, the bifacial solar panel device 120 allows the first solar panel and the second solar panel to operate simultaneously for photoelectric conversion, the first solar panel faces the sky to directly absorb sunlight, and the second solar panel faces the ground to absorb sunlight reflected by the ground, so as to improve the overall photoelectric conversion efficiency.

The drive module 122 is connected to the sensor module 121 to drive the stepper motor to control the rotation of the shaft when the integrity of the solar panel is lower than the allowable value, so that the double-sided solar panel device flips. In actual implementation, the stepper motor can control the rotation of the shaft by 180 degrees to flip the double-sided solar panel device 120 vertically. In addition, the allowable value can be a pre-set percentage. For example, assuming that the allowable value is "40%", when the number of abnormalities is 80%, the integrity is 20%. At this time, the integrity is lower than the allowable value, so the drive module 122 will drive the stepper motor to control the rotation of the shaft.

The communication module 123 is connected to the driving module 122, and is used to generate a warning signal containing a recorded unique identification code to be transmitted to the remote device 110 when the stepper motor stops rotating and the double-sided solar panel device 120 completes flipping. In actual implementation, the frame may include an unlocking element, which allows receiving a replacement signal from the automatic device 130 after the double-sided solar panel device 120 transmits the warning signal, and enables the unlocking element according to the received replacement signal to unlock the solar panel facing the ground for replacement. In fact, before enabling the unlocking element, the stepper motor can be driven to rotate the shaft so that the double-sided solar panel device 120 is parallel to the horizon to facilitate the removal of the solar panel. In addition, the communication module 123 can transmit the warning signal to the remote device 110 through the network (such as Wi-Fi, ZigBee, CoAP (Constrained Application Protocol), MQTT (Message Queuing Telemetry Transport) or similar wireless transmission technologies.

Please refer to "FIG. 2", which is a flow chart of the method of solar panel backup of the present invention, wherein the steps include: a rotating shaft 320 is provided through the horizontal center line of the frame 310, and solar panels (311, 312) with unique identification codes are respectively provided on opposite sides of the frame 310 to form a double-sided solar panel device 300, and a plurality of sensors are provided on the solar panels (311, 312) (step 210); the double-sided solar panel device 300 continuously senses the ratio of the normal operation quantity and the abnormal quantity of the sensors to calculate the solar panel (311, 312), and records the unique identification code of the abnormal solar panel (311, 312) (step 220); when the integrity of the solar panel (311, 312) is lower than the allowable value, the bifacial solar panel device 300 drives the stepper motor to control the rotation shaft 320 to rotate, so that the bifacial solar panel device 300 turns over (step 230); when the stepper motor stops rotating and the bifacial solar panel device 300 completes the turning over, the bifacial solar panel device 300 generates a warning signal including the recorded unique identification code to be transmitted to the remote device (step 240). Through the above steps, a double-sided solar panel device 300 can be formed by respectively arranging solar panels (311, 312) on opposite sides of a frame 310, a rotating shaft 320 is passed through the horizontal center line of the frame 310, and a plurality of sensors are arranged on the solar panels (311, 312) to continuously detect the completeness of the solar panels (311, 312). When the sensor detects that the integrity of the solar panels (311, 312) is lower than the allowable value, the stepper motor is driven to control the rotation of the shaft 320, thereby completing the flip of the double-sided solar panel device 300, and at the same time, a warning signal containing a unique identification code is transmitted to the remote device to notify the administrator to replace the damaged solar panels (311, 312).

The following is explained in the form of an embodiment in conjunction with "Figure 3" and "Figure 4". Please refer to "Figure 3" first. "Figure 3" is a schematic diagram of a double-sided solar panel device to which the present invention is applied. In actual implementation, the double-sided solar panel device 300 has a frame 310, a rotating shaft 320 is passed through the horizontal center line of the frame 310, and solar panels (311, 312) with unique identification codes are respectively arranged on opposite sides of the frame 310, and the solar panels are simultaneously provided with multiple sensors. In actual use, the double-sided solar panel device 300 can face the sun to obtain better photoelectric conversion efficiency. When the double-sided solar panel device 300 is hit by an external force, causing the solar panel 311 on the first side to be partially damaged, the corresponding part of the sensor will not work. At this time, the sensor module 121 will calculate the integrity of the solar panel 311 according to the ratio of the normal operation quantity and the abnormal quantity of the sensor (for example, if the abnormal quantity is 80%, the integrity is 20%), and record the unique identification code of the solar panel 311. Then, assuming that the integrity is lower than the preset allowable value (for example, 50%), the drive module 122 will drive the stepper motor to control the rotation shaft 320 to rotate, so that the double-sided solar panel device 300 is turned over, and the solar panel 312 on the second side faces the sun. Next, when the stepper motor of the bifacial solar panel device 300 stops rotating, that is, when the bifacial solar panel device 300 has completed the flipping, a warning signal containing a recorded unique identification code is generated and transmitted to the remote device 110. In this way, the administrator of the remote device 110 can determine that the fault is the first solar panel 311 according to the unique identification code in the warning signal, and even further instruct the maintenance personnel to go for maintenance. At the same time, because the bifacial solar panel device 300 has flipped, the good second solar panel 312 is turned upward to face the sunlight, effectively and immediately avoiding the first solar panel 311 from being partially damaged and affecting the photoelectric conversion efficiency.

As shown in FIG. 4 , which is a schematic diagram of replacing a solar panel using the present invention, it is assumed that the second solar panel 312 is damaged and its integrity is lower than the allowable value. After the double-sided solar panel device 300 sends a warning signal to the remote device 110 , the double-sided solar panel device 300 allows receiving a replacement signal from the automatic device 130 , and enables the unlocking element ( 411 , 412 ) according to the received replacement signal to unlock the solar panel 312 facing the ground for replacement. In actual implementation, the mobile device 130 can be a portable device such as a tablet computer, a smart phone, a laptop computer, etc., and can trigger the generation of a replacement signal through instant messaging software, text messages, or emails. In particular, in order to facilitate the removal and replacement of the second solar panel 312, before enabling the unlocking element (411, 412), the stepper motor can be driven to rotate the shaft so that the double-sided solar panel device 300 is parallel to the horizon.

In summary, the difference between the present invention and the prior art is that solar panels are arranged on opposite sides of a frame to form a double-sided solar panel device. A rotating shaft is provided through the horizontal center line of the frame, and multiple sensors are provided on the solar panel to continuously detect the integrity of the solar panel. When the sensor senses that the integrity of the solar panel is lower than the allowable value, the stepper motor is driven to control the rotating shaft to rotate, thereby completing the flipping of the double-sided solar panel device, and at the same time, a warning signal containing a unique identification code is transmitted to the remote device to notify the manager to replace the damaged solar panel. This technical means can solve the problems existing in the prior art, thereby achieving the technical effect of improving the timeliness of the maintenance of the solar panel device.

Although the present invention is disclosed as above by the aforementioned embodiments, it is not intended to limit the present invention. Anyone familiar with similar techniques can make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be subject to the scope of the patent application attached to this specification.
