BC photovoltaic panel management method and system applied to the Shago desert region

Abstract

The present application relates to the field of new energy technology, and in particular to a BC photovoltaic panel management method and system applied to the Shagohuang area. The purpose of this technical solution, that is, the preset requirement, is to ensure that the plants under the BC photovoltaic panels can get sufficient light during the day. Each BC photovoltaic panel has its corresponding planting area. First, it is necessary to divide the planting area corresponding to each BC photovoltaic panel, and then divide the planting area corresponding to each BC photovoltaic panel into grids, so as to monitor the illuminance value of each grid to determine the grid that needs to be supplemented with light. During implementation, the illuminance value statistics of each grid are performed once every short period. When the illuminance value of a certain grid is low within the period, the shadow of the current BC photovoltaic panel can be transferred to other grids by controlling the overall translation or disintegration translation of the current BC photovoltaic panel to prevent the plants from being in the shadow for a long time and unable to photosynthesize, resulting in poor development.

Description

Technical Field

[0001] This application relates to the field of new energy technology, and in particular to a BC photovoltaic panel management method and system for use in the desert region. Background Technology

[0002] "Shagohuang" is an abbreviation for desert, Gobi and arid regions. Data shows that the Shagohuang region is the richest in solar and wind energy resources. With the construction of large-scale wind and solar power bases, the Shagohuang region has become a new hotbed for energy.

[0003] In recent years, an increasing number of photovoltaic (PV) manufacturing companies have chosen to invest and build in the Gobi Desert region. Various manufacturing enterprises and raw material suppliers from upstream to downstream have successively settled in the area, and the PV manufacturing industry is expanding from being concentrated in one or two links to a coordinated layout across the entire industrial chain. At the Tengger Desert wind and solar power base, a new path of "new energy construction + protection and restoration of the Gobi Desert ecosystem" has been successfully explored, realizing a new business model of "power generation on the panel, planting between panels, and restoration beneath the panel." BC (back-contact) PV panels, as one of the most preferred PV panels currently available, can now be applied on a large scale in the Gobi Desert region for "new energy construction + protection and restoration of the Gobi Desert ecosystem."

[0004] During implementation, a single-pile high support for the BC photovoltaic panel is required, with the pile support point about 3 meters above the ground. Then, seeds of desert plants such as Artemisia argyi, Artemisia argyi, Artemisia argyi, Kochia scoparia, and Crassula mongholica are sown under the BC photovoltaic panel. Shrubs such as Salix psammophila and Salix matsudana can also be planted, thus forming a new forestry and desert industry model that combines light, forestry, and grass, realizing "power generation on the panel, planting between the panels, and restoration under the panel".

[0005] However, in the process of developing the new photovoltaic industry model of "power generation on the panel, planting between the panels, and restoration under the panel", some plants under the BC photovoltaic panels are not receiving enough sunlight every day due to the shadow of the BC photovoltaic panels, resulting in poor development and a clear difference from the surrounding plants. Summary of the Invention

[0006] To at least partially overcome the problem in related technologies that some plants under BC photovoltaic panels suffer from insufficient daily sunlight and thus poor development due to shading by the BC photovoltaic panels during the new business model of "power generation on photovoltaic panels, planting between panels, and restoration under panels", this application provides a BC photovoltaic panel management method and system applicable to desert areas.

[0007] The proposed solution is as follows:

[0008] According to a first aspect of the embodiments of this application, a method for managing BC photovoltaic panels applied in the Sago Desert region is provided, comprising:

[0009] Obtain weather information and generate BC photovoltaic panel management orders based on preset weather conditions and the weather information;

[0010] When the BC photovoltaic panel management order instructs the execution of BC photovoltaic panel management, the planting area corresponding to each BC photovoltaic panel is divided.

[0011] The planting area corresponding to each BC photovoltaic panel is divided into a grid;

[0012] Real-time acquisition of illuminance values ​​for each grid within the planting area corresponding to the current photovoltaic panel;

[0013] The changes in illuminance values ​​for each grid cell within a period of time are statistically analyzed; the period is no longer than one hour.

[0014] Based on the changes in the illuminance values ​​of each grid within the period, the current BC photovoltaic panel is controlled to be moved as a whole or disassembled and moved separately, so that the average illuminance of each grid within the day meets the preset requirements.

[0015] Preferably, based on the change in illuminance values ​​of each grid within a period, the current BC photovoltaic panel is controlled to undergo overall translation or disassembled translation, including:

[0016] Grids whose average illuminance in the previous period was lower than the first illuminance threshold are considered as grids to be supplemented with light in the current period.

[0017] When a grid to be supplemented with light appears in the current cycle, determine whether the grids to be supplemented with light are adjacent;

[0018] If the grids to be supplemented with light are adjacent, determine whether the grids to be supplemented with light are located in the central area of ​​the planting area;

[0019] If the grid to be supplemented with light is not in the central area of ​​the planting area, control the current BC photovoltaic panel to be shifted as a whole so that the average illuminance of each grid during the day meets the preset requirements;

[0020] If the grid to be supplemented with light is located in the central area of ​​the planting area, the current BC photovoltaic panel is controlled to disassemble and translate so that the average illuminance of each grid during the day meets the preset requirements;

[0021] If the grids to be supplemented with light in the current cycle are not adjacent, the current BC photovoltaic panel is controlled to disassemble and shift so that the average illuminance of each grid during the day meets the preset requirements.

[0022] Preferably, the method further includes:

[0023] Grids whose average illuminance in the previous period is higher than the second illuminance threshold are considered as grids to be converted to light in the current period.

[0024] Determine the change in illuminance of the grid to be supplemented and the grid to be converted after each translation of the current BC photovoltaic panel;

[0025] Based on the illuminance changes of the grid to be supplemented and the grid to be converted, a first stop condition and a second stop condition are set when the BC photovoltaic panel is translated, so as to control the overall translation or disassembly translation to stop.

[0026] The first stopping condition is that the increase in illuminance of the grid to be supplemented exceeds a first preset value;

[0027] The second stopping condition is that the decrease in illuminance of the grid to be converted exceeds a second preset value.

[0028] Preferably, the current BC photovoltaic panels are controlled to be shifted as a whole so that the average illuminance of each grid during the day meets the preset requirements, including:

[0029] Control the current BC photovoltaic panel to move as a whole in the current direction;

[0030] If both the first and second stopping conditions are met, then the translation stops.

[0031] If the first and second stopping conditions are not met simultaneously, the translation direction is adjusted and the translation is repeated until both conditions are met simultaneously.

[0032] Preferably, the current BC photovoltaic panel is controlled to disassemble and translate so that the average illuminance of each grid during the day meets a preset requirement, including:

[0033] Sequentially control each part of the current BC photovoltaic panel to translate in different directions;

[0034] Stop translating the current part when the first stopping condition and / or the second stopping condition are met after the current part has been translated.

[0035] After each part of the BC photovoltaic panel has completed one translation, the translation will stop if both the first and second stopping conditions are met simultaneously.

[0036] If the first and second stopping conditions are not met simultaneously, then control the remaining parts of the BC photovoltaic panel, excluding the stopped translation part, to adjust the translation direction in sequence and start translating again until the first and second stopping conditions are met simultaneously.

[0037] Preferably, the method further includes:

[0038] If there is no grid to be converted into light in the current cycle, the second stopping condition is assumed to be met when controlling the current BC photovoltaic panel to perform overall translation or disassembled translation.

[0039] Preferably, the method further includes:

[0040] Obtain an image of the planting area corresponding to the current photovoltaic panel;

[0041] Send the image of the planting area corresponding to the current photovoltaic panel, as well as the change of the illuminance value of each grid within the period, to the control center;

[0042] Receive translation commands from the control center;

[0043] The translation command controls the current BC photovoltaic panel to be translated as a whole or disassembled and translated.

[0044] Preferably, the method further comprises:

[0045] Real-time detection of the energy storage capacity of the current area energy storage unit corresponding to the current BC photovoltaic panel; the current area energy storage unit is used to supply power to the plant management system in the planting area corresponding to the current BC photovoltaic panel;

[0046] When the energy storage capacity of the current regional energy storage unit is higher than the first energy storage threshold, all the electricity generated by the current BC photovoltaic panels will be transmitted to the total energy storage unit.

[0047] When the energy storage capacity of the current regional energy storage unit is lower than the second energy storage threshold, all the electricity generated by the current BC photovoltaic panels will be transmitted to the current regional energy storage unit.

[0048] When the energy storage capacity of the current regional energy storage unit is between the first energy storage threshold and the second energy storage threshold, the electricity generated by the current BC photovoltaic panel is transmitted to the total energy storage unit and the regional energy storage unit of the corresponding planting area in a set proportion.

[0049] Preferably, the method further comprises:

[0050] Real-time monitoring of humidity on the underside of each BC photovoltaic panel;

[0051] An alarm will be triggered when the humidity in the bottom area of ​​the BC photovoltaic panel exceeds the preset humidity alarm threshold.

[0052] If, after an alarm is triggered, the humidity on the bottom surface of the BC photovoltaic panel remains higher than the preset humidity alarm threshold within the preset maintenance period, power will be supplied to the dehumidification module installed on the bottom surface of the BC photovoltaic panel.

[0053] According to a second aspect of the embodiments of this application, a BC photovoltaic panel management system for use in the Sakhalin Desert region is provided, comprising:

[0054] The weather acquisition module is used to acquire weather information and generate BC photovoltaic panel management commands based on preset weather conditions and weather information.

[0055] The area division module is used to divide the planting area corresponding to each BC photovoltaic panel when the BC photovoltaic panel management order instructs the execution of BC photovoltaic panel management;

[0056] The grid division module is used to divide the planting area corresponding to each BC photovoltaic panel into a grid.

[0057] The illuminance acquisition module is used to acquire the illuminance values ​​of each grid in the planting area corresponding to the current photovoltaic panel in real time;

[0058] The statistics module is used to count the changes in illuminance values ​​of each grid within a period; the period is no more than one hour.

[0059] The control module is used to control the current BC photovoltaic panel to perform overall translation or disassembled translation based on the changes in the illuminance value of each grid within the period, so that the average illuminance of each grid within the day meets the preset requirements.

[0060] The technical solution provided in this application may include the following beneficial effects: The BC photovoltaic panel management method applied to the desert area in this application includes: acquiring weather information, generating a BC photovoltaic panel management order based on preset weather conditions and weather information; dividing the planting area corresponding to each BC photovoltaic panel when the photovoltaic panel management order instructs the execution of BC photovoltaic panel management; dividing the planting area corresponding to each BC photovoltaic panel into a grid; acquiring the illuminance value of each grid in the planting area corresponding to the current photovoltaic panel in real time; statistically analyzing the change of the illuminance value of each grid within a period; the period is no more than one hour; and controlling the current BC photovoltaic panel to perform overall translation or disassembly translation based on the change of the illuminance value of each grid within a period, so that the average illuminance of each grid within the day meets the preset requirements.

[0061] The background of this technical solution is planting desert plants under BC photovoltaic panels. The purpose of this solution, namely the pre-set requirement, is to ensure that the plants under the BC photovoltaic panels receive sufficient sunlight throughout the day. During implementation, weather information is first obtained, and on sunny days, BC photovoltaic panel management is executed via a management command. Each BC photovoltaic panel has its corresponding planting area, which needs to be divided into grids to monitor the illuminance values ​​of each grid and determine which grids require supplemental lighting. During implementation, the illuminance values ​​of each grid are statistically analyzed at short intervals. When the illuminance value of a particular grid is consistently low within a period, the BC photovoltaic panel can be moved entirely or disassembled to shift the shadow of the current BC photovoltaic panel to other grids, preventing the plants from being in shadow for extended periods and hindering photosynthesis, thus preventing stunted growth.

[0067] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0068] Example 1

[0069] Figure 1 This is a flowchart illustrating a BC photovoltaic panel management method applied in the Sago Desert region, as provided in one embodiment of this application. (Refer to...) Figure 1 A method for managing BC photovoltaic panels in the Sago Desert region, comprising:

[0070] S11: Obtain weather information and generate BC photovoltaic panel management orders based on preset weather conditions and weather information;

[0071] In this technical solution, considering that the desert region also experiences rainfall and cloudy weather, weather information is acquired, and BC photovoltaic panel management commands are generated based on preset weather conditions and the weather information. Specifically, a BC photovoltaic panel management command to stop BC photovoltaic panel management is generated on cloudy or rainy days, and a BC photovoltaic panel management command to execute BC photovoltaic panel management is generated on sunny days.

[0072] In practice, weather information can be forecasts for the current location or current weather information obtained using devices such as cameras. Preset weather conditions can be either unsuitable or suitable for BC photovoltaic panel management.

[0073] If the obtained weather information is a weather forecast for the current location, the forecast information is matched with preset weather conditions to obtain a BC photovoltaic panel management order; if the obtained weather information is current weather information obtained using components such as cameras, the weather information needs to be analyzed first to draw a conclusion about the weather conditions, and then the conclusion about the weather conditions is matched with preset weather conditions to obtain a BC photovoltaic panel management order.

[0074] S12: When the BC photovoltaic panel management order instructs the implementation of BC photovoltaic panel management, divide the planting area corresponding to each BC photovoltaic panel;

[0075] In practice, the BC photovoltaic panels are spaced apart to allow for relocation. In this case, the planting area corresponding to the BC photovoltaic panel is larger than the area occupied by the BC photovoltaic panel.

[0076] S13: Divide the planting area corresponding to each BC photovoltaic panel into a grid;

[0077] In practice, grids can be divided according to the planting spacing of the plants. For example, if the planting spacing of the plants is 0.4m, then grids can be divided at intervals of 0.4m.

[0078] S14: Real-time acquisition of illuminance values ​​for each grid in the planting area corresponding to the current photovoltaic panel;

[0079] In this embodiment, the illuminance value of the grid can be obtained by setting up an illuminance sensor in the grid.

[0080] In specific settings, the light sensor should be positioned higher than the plant to prevent it from being blocked by the plant's shadow.

[0081] S15: Statistically analyze the changes in illuminance values ​​for each grid within a period; the period shall not exceed one hour.

[0082] Preferably, the change in illuminance values ​​of each grid is statistically analyzed within a half-hour period.

[0083] Preferably, the change in illuminance values ​​of each grid within a period can be presented using a graph.

[0084] S16: Based on the changes in the illuminance values ​​of each grid within the period, control the current BC photovoltaic panel to perform overall translation or disassembled translation so that the average illuminance of each grid within the day meets the preset requirements.

[0085] In this embodiment, a complete BC photovoltaic panel is composed of 4 or 6 BC photovoltaic sub-panels. Each BC photovoltaic sub-panel has an individual support underneath, and the support can drive the BC photovoltaic sub-panel to move horizontally through a transmission mechanism. If all BC photovoltaic sub-panels move in one direction, it is called overall horizontal movement. If each BC photovoltaic sub-panel moves in different directions, it is called disassembly horizontal movement.

[0086] Each BC photovoltaic panel generates electricity independently, and the electricity generated by each BC photovoltaic panel is then transmitted to the same energy storage unit.

[0087] It should be noted that the preset requirement in this embodiment is to ensure that the average daily illuminance of each grid is above the acceptable level for normal growth, that is, to ensure that the plants in each grid can receive sufficient sunlight during the day.

[0088] It should be noted that, based on the changes in illuminance values ​​of each grid within the period, the current BC photovoltaic panel is controlled to undergo either overall translation or disassembled translation, including:

[0089] Grids whose average illuminance in the previous period was lower than the first illuminance threshold are considered as grids to be supplemented with light in the current period.

[0090] When a grid to be supplemented with light appears in the current cycle, determine whether the grids to be supplemented with light are adjacent;

[0091] If the grids to be supplemented with light are adjacent, determine whether the grids to be supplemented with light are located in the central area of ​​the planting area;

[0092] If the grid to be supplemented with light is not in the central area of ​​the planting area, control the current BC photovoltaic panel to be shifted as a whole so that the average illuminance of each grid during the day meets the preset requirements;

[0093] If the grid to be supplemented with light is located in the central area of ​​the planting area, the current BC photovoltaic panel is controlled to disassemble and translate so that the average illuminance of each grid during the day meets the preset requirements;

[0094] If the grids to be supplemented with light in the current cycle are not adjacent, the current BC photovoltaic panel is controlled to disassemble and shift so that the average illuminance of each grid during the day meets the preset requirements.

[0095] Furthermore, the methods also include:

[0096] Grids whose average illuminance in the previous period is higher than the second illuminance threshold are considered as grids to be converted to light in the current period.

[0097] Determine the change in illuminance of the grid to be supplemented and the grid to be converted after each translation of the current BC photovoltaic panel;

[0098] Based on the illuminance changes of the grid to be supplemented and the grid to be converted, the first and second stopping conditions are set when the BC photovoltaic panel is translated, so as to control the overall translation or disassembly translation to stop.

[0099] The first stopping condition is that the increase in illuminance of the grid to be supplemented exceeds a first preset value;

[0100] The second stopping condition is that the decrease in illuminance of the grid to be converted exceeds a second preset value.

[0101] In this technical solution, grids with an average illuminance lower than the first illuminance threshold in the previous cycle are considered as grids requiring supplemental lighting in the current cycle. These grids are those with low illuminance in the previous cycle, and can be identified as grids in shadow in the previous cycle. Grids with an average illuminance higher than the second illuminance threshold in the previous cycle are considered as grids requiring conversion to sunlight. These grids have sufficient illuminance in the previous cycle, and can be identified as grids continuously exposed to sunlight. In this case, the shadows in the grids requiring supplemental lighting can be transferred to the grids requiring conversion to sunlight by controlling the translation of the current BC photovoltaic panels, thereby achieving a balance of overall illuminance across all grids during the day.

[0102] In this embodiment, it is first determined whether the grids to be supplemented with light in the current cycle are adjacent; if the grids to be supplemented with light in the current cycle are adjacent, it is determined whether the grids to be supplemented with light are located in the central area of ​​the planting area.

[0103] If the grid to be supplemented with light is not in the center of the planting area, it means that the shadow generated by the BC photovoltaic panel is at the edge of the planting area. In this case, the current BC photovoltaic panel can be moved as a whole.

[0104] If the grid to be supplemented with light is located in the central area of ​​the planting area, it means that the shadow generated by the BC photovoltaic panel is located in the central area of ​​the planting area. At this time, controlling the current BC photovoltaic panel to disassemble and translate can directly disperse the shadow in the center of the planting area.

[0105] If the grids to be supplemented with light in the current cycle are not adjacent, it means that the shadows generated by the BC photovoltaic panels are located in various directions of the planting area. At this time, it is necessary to control the current BC photovoltaic panels to disassemble and translate them. Multiple BC photovoltaic panels are displaced to simultaneously satisfy the first and second stopping conditions.

[0106] It should be noted that if the increase in illuminance of the grid to be supplemented after the current translation of the BC photovoltaic panel exceeds the first preset value, it means that the current translation of the BC photovoltaic panel has caused the grid to be supplemented to escape from the shadow, and this is taken as the first stopping condition for the translation of the BC photovoltaic panel.

[0107] If the illuminance decrease of the grid to be converted after the current BC photovoltaic panel is translated exceeds the second preset value, it means that the current translation of the BC photovoltaic panel has caused the grid to be converted to enter the shadow, and this is taken as the second stopping condition for the translation of the BC photovoltaic panel.

[0108] Specifically, the current BC photovoltaic panels are controlled to be shifted as a whole to ensure that the average daily illuminance of each grid meets the preset requirements, including:

[0109] Control the current BC photovoltaic panel to move as a whole in the current direction;

[0110] If both the first and second stopping conditions are met, then the translation stops.

[0111] If the first and second stopping conditions are not met simultaneously, the translation direction is adjusted and the translation is repeated until both conditions are met simultaneously.

[0112] It should be noted that in practice, there are multiple ways to perform a complete translation, for example:

[0113] 1) First, control the current BC photovoltaic panel to move as a whole to the north. If the first and second stopping conditions are not met at the same time, return to the starting point and adjust the translation direction to the northeast for overall translation. If the first and second stopping conditions are not met at the same time, return to the starting point and adjust the translation direction to the east for overall translation, and so on.

[0114] 2) First, control the current BC photovoltaic panel to move as a whole to the north. If the first and second stopping conditions are not met at the same time, move clockwise or counterclockwise around the starting point.

[0115] It should be noted that the above two overall translation methods are merely illustrative examples. In practice, other translation methods can also be used, as long as the first and second stopping conditions are satisfied simultaneously through the overall translation.

[0116] Specifically, the current BC photovoltaic panels are disassembled and shifted to ensure that the average daily illuminance of each grid meets preset requirements, including:

[0117] Sequentially control each part of the current BC photovoltaic panel to translate in different directions;

[0118] Stop translating the current part when the first stopping condition and / or the second stopping condition are met after the current part has been translated.

[0119] After each part of the BC photovoltaic panel has completed one translation, the translation will stop if both the first and second stopping conditions are met simultaneously.

[0120] If the first and second stopping conditions are not met simultaneously, then control the remaining parts of the BC photovoltaic panel, excluding the stopped translation part, to adjust the translation direction in sequence and start translating again until the first and second stopping conditions are met simultaneously.

[0121] In this embodiment, when controlling the disassembly and translation of the current BC photovoltaic panel, it is necessary to sequentially control each part of the current BC photovoltaic panel to translate in different directions. When the translation of the current part meets either the first or the second stopping condition, the translation of the current part stops, and the translation of the remaining part is used to meet the other stopping condition. When both the first and the second stopping conditions are met after the translation of the current part, the translation work is completed.

[0122] When moving the various parts of the BC photovoltaic panel (BC photovoltaic sub-panels), the same overall translation method described above can be used, and will not be repeated here.

[0123] It should be noted that the method also includes:

[0124] If there is no grid to be converted into light in the current cycle, the second stopping condition is assumed to be met when controlling the current BC photovoltaic panel to perform overall translation or disassembled translation.

[0125] The purpose of this technical solution is to ensure that the plants under the BC photovoltaic panel receive sufficient light throughout the day. Therefore, the prerequisite is that there is a grid of light to be supplemented in the current cycle. At this time, the shadows in the grid of light to be supplemented must be transferred by translating the BC photovoltaic panel.

[0126] Therefore, in practice, there may be situations where there is no grid to be converted into light within the current cycle. In this case, when controlling the current BC photovoltaic panel to perform overall translation or disassembled translation, there is no need to consider the second stopping condition. As long as the first stopping condition is met, the translation can be completed.

[0127] It should be noted that the method also includes:

[0128] Obtain an image of the planting area corresponding to the current photovoltaic panel;

[0129] Send the image of the planting area corresponding to the current photovoltaic panel, as well as the change of the illuminance value of each grid within the period, to the control center;

[0130] Receive translation commands from the control center;

[0131] The current BC photovoltaic panel is controlled to be moved as a whole or disassembled and moved according to the translation command.

[0132] In this embodiment, the image of the planting area corresponding to the photovoltaic panel and the change of the illuminance value of each grid within the period are also sent to the control center. This allows the staff at the control center to make manual fine adjustments based on the image of the planting area and the illuminance value of each grid, making it easier for the average illuminance of each grid to meet the preset requirements during the day.

[0133] The background of this technical solution is planting desert plants under BC photovoltaic panels. The purpose of this solution, namely the pre-set requirement, is to ensure that the plants under the BC photovoltaic panels receive sufficient sunlight throughout the day. Each BC photovoltaic panel has its corresponding planting area. First, it is necessary to divide the planting area corresponding to each BC photovoltaic panel, and then divide the planting area corresponding to each BC photovoltaic panel into a grid to monitor the illuminance value of each grid to determine which grids need supplemental lighting. During implementation, the illuminance value of each grid is statistically analyzed at short intervals. When the illuminance value of a certain grid is low throughout the period, the shadow of the current BC photovoltaic panel can be shifted to other grids by controlling the overall translation or disassembly translation of the current BC photovoltaic panel, thus preventing the plants from being in the shadow for a long time and thus being unable to photosynthesize, leading to poor development.

[0134] Example 2

[0135] It should be noted that the method also includes:

[0136] Real-time detection of the energy storage capacity of the current area energy storage unit corresponding to the current BC photovoltaic panel; the current area energy storage unit is used to supply power to the plant management system in the planting area corresponding to the current BC photovoltaic panel;

[0137] When the energy storage capacity of the current regional energy storage unit is higher than the first energy storage threshold, all the electricity generated by the current BC photovoltaic panels will be transmitted to the total energy storage unit.

[0138] When the energy storage capacity of the current regional energy storage unit is lower than the second energy storage threshold, all the electricity generated by the current BC photovoltaic panels will be transmitted to the current regional energy storage unit.

[0139] When the energy storage capacity of the current regional energy storage unit is between the first energy storage threshold and the second energy storage threshold, the electricity generated by the current BC photovoltaic panel is transmitted to the total energy storage unit and the regional energy storage unit of the corresponding planting area in a set proportion.

[0140] When implementing the new photovoltaic business model of "power generation on the panel, planting between panels, and restoration under the panel," the plants planted under the BC photovoltaic panels are managed automatically through a plant management system. This system typically includes water circulation and fertilization equipment to achieve automated plant management.

[0141] The plant management system is equipped with regional energy storage units to supply power to various devices.

[0142] In this embodiment, the electricity generated by the BC photovoltaic panel is transmitted to the regional energy storage unit in the plant management system to maintain the operation of various devices in the plant management system.

[0143] In practice, the electrical energy delivered to the regional energy storage units is allocated based on their energy storage capacity. When the energy storage capacity of a current regional energy storage unit is higher than the first energy storage threshold, it indicates that the current regional energy storage unit is sufficient to maintain the operation of all equipment in the plant management system, and no additional electrical energy is required. In this case, all the electrical energy generated by the current BC photovoltaic panels is delivered to the total energy storage unit, and the first energy storage threshold can be 80%.

[0144] When the energy storage capacity of the current regional energy storage unit is lower than the second energy storage threshold, it means that the current regional energy storage unit will soon be unable to maintain the operation of the equipment in the plant management system. At this time, all the electricity generated by the current BC photovoltaic panel will be transferred to the current regional energy storage unit. The first energy storage threshold can be 20%.

[0145] When the energy storage capacity of the current regional energy storage unit is between the first energy storage threshold and the second energy storage threshold, it means that the current regional energy storage unit can maintain the operation of each device in the plant management system, but still needs to be replenished. At this time, the electricity generated by the current BC photovoltaic panel is delivered to the total energy storage unit and the regional energy storage unit of the corresponding planting area in a set ratio. The set ratio can be 1:1.

[0146] Example 3

[0147] It should be noted that the method also includes:

[0148] Real-time monitoring of humidity on the underside of each BC photovoltaic panel;

[0149] An alarm will be triggered when the humidity in the bottom area of ​​the BC photovoltaic panel exceeds the preset humidity alarm threshold.

[0150] If, after an alarm is triggered, the humidity on the bottom surface of the BC photovoltaic panel remains higher than the preset humidity alarm threshold within the preset maintenance period, power will be supplied to the dehumidification module installed on the bottom surface of the BC photovoltaic panel.

[0151] The most significant feature of BC photovoltaic panels is that both the emitter and base electrodes are located on the back of the cell, thus reducing shading and improving photoelectric conversion efficiency. However, in the implementation of this technical solution, plants are grown beneath the BC photovoltaic panels, and a plant management system is installed. This system includes a water circulation device, which inevitably generates water vapor. This rising water vapor may adhere to the bottom surface of the BC photovoltaic panels, affecting their operation.

[0152] In this embodiment, a humidity sensor is installed on the bottom surface of the BC photovoltaic panel to detect the humidity of each BC photovoltaic panel in real time. When the humidity of the current BC photovoltaic panel bottom surface area is higher than the preset humidity alarm threshold, an alarm can be triggered by sending a text message to the mobile terminal of the management personnel.

[0153] If, after an alarm is triggered, the humidity in the area under the BC photovoltaic panel remains higher than the preset humidity alarm threshold within the preset maintenance time, it is determined that the management personnel have not arrived on site to handle the issue. In this case, power is supplied to the dehumidification module installed on the bottom of the BC photovoltaic panel to dehumidify the area under the BC photovoltaic panel.

[0154] This technical solution takes into account the high power consumption of the dehumidification module, so manual handling by management personnel is preferred first. Only when manual handling is not feasible will the dehumidification module be used for processing.
