DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0022] The terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish between different objects, not to describe a particular order. Furthermore, the terms "including," "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0023] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0024] See also Figure 1 , Figure 1 The present invention provides a flow chart of a method for evaluating the health status of a solar panel. Figure 1 As shown, the method includes: 101. Acquire current output power information of a solar cell panel to obtain first output power information, and acquire current environment information of the solar cell panel to obtain first environment information.

[0025] The current output power of the solar cell panel may be detected by a power detection device to obtain the first output power.

[0026] The current environmental information includes the current light intensity, temperature information of the solar panel, and humidity information.

[0027] Specifically, the current light intensity can be obtained through the light intensity sensor, and the temperature and humidity information can be obtained through the temperature and humidity sensor. The temperature and humidity sensor is set near the solar panel to detect the temperature and humidity information of the environment in which it is located.

[0028] 102. Determine reference output power information of the solar panel according to the first environmental information.

[0029] Specifically, a method for determining reference output power information of the solar panel according to the first environmental information includes: A1. Extracting light intensity information, temperature information, and humidity information of the solar panel from the first environmental information; A2. Determine first sub-output power information according to the temperature information and the humidity information; A3. Determine second sub-output power information according to the light intensity information; A4. Fusing the first sub-output power information and the second sub-output power information to obtain the reference output power information.

[0030] Among them, the output power of the solar panel will be affected at different temperatures. For example, when the temperature rises, its output efficiency will decrease, resulting in a decrease in output power. Therefore, the corresponding power can be determined based on the mapping relationship between the temperature value and the output power; at the same time, the corresponding power can also be determined based on the mapping relationship between the humidity information and the output power. Finally, the sum of the two powers is determined as the first sub-output power information.

[0031] As the light intensity increases, the corresponding output power increases, and as the light intensity decreases, the corresponding output power decreases. Thus, the output power corresponding to the light intensity indicated by the light intensity information can be determined, and the output power is determined as the second sub-output power information.

[0032] Finally, the sum of the first sub-output power information and the second sub-output power information is determined as the reference output power information.

[0033] 103. Determine output power correction information according to historical status information of the solar cell panel.

[0034] Specifically, a method for determining output power correction information based on historical status information of the solar cell panel includes: B1. determining output power fluctuation information according to the historical status information; B2. Determine output power correction information according to the output power fluctuation information.

[0035] A common power fluctuation information extraction method can be used to extract output power fluctuation information from historical state information. Finally, the output power fluctuation information is input into a preset power correction information model for prediction processing to obtain output power correction information. The power correction information model is a pre-trained model used to generate output power correction information, and its model structure can be a CNN model.

[0036] Specifically, another method for determining output power correction information based on historical status information of the solar cell panel includes: C1. Determine a state fluctuation graph based on the historical state information; C2. determining state deviation trend information according to the state fluctuation graph; C3. Determine output power correction information according to the state deviation trend information.

[0037] In a state fluctuation graph, each historical state information corresponds to a fluctuation point, and the fluctuation points are connected in chronological order to form a state fluctuation graph. In the state fluctuation graph, the state deviation trend information can be determined based on the slope change trend. Specifically, the slope change trend can be determined as the state deviation trend information.

[0038] Finally, a prediction can be made based on the state deviation trend information. For example, the output power can be predicted based on the value and slope change trend of the last fluctuation point in the state fluctuation graph to obtain a predicted value. Output power correction information can then be determined based on the predicted value. For example, the output power correction information corresponding to the state deviation trend information can be determined based on a mapping relationship between the predicted value and the output power correction information.

[0039] 104. Use the output power correction information to correct the reference output power information to obtain target output power information.

[0040] The product of the output power correction information and the reference output power information may be determined as the target output power information.

[0041] 105. Determine health status information of a solar cell panel according to the first output power information and the target output power information.

[0042] The target output power information can be determined by the following method: D1. Obtaining an offset between the first output power information and the target output power information to obtain a first power offset; D2. extracting an offset interval corresponding to the first offset; D3. Determine health status information based on the offset interval.

[0043] The offset between the first output power information and the target output power information can be understood as the difference between the power value corresponding to the first output power information and the power value corresponding to the target output power information. The difference can be positive or negative.

[0044] Different offset intervals have corresponding health status information, so the health status information corresponding to the offset interval corresponding to the first offset can be determined.

[0045] In this example, current output power information of the solar panel is obtained to obtain first output power information, and current environmental information of the solar panel is obtained to obtain first environmental information. Reference output power information of the solar panel is determined based on the first environmental information. Output power correction information is determined based on historical status information of the solar panel. The reference output power information is corrected using the output power correction information to obtain target output power information. Health status information of the solar panel is determined based on the first output power information and the target output power information. Therefore, health status assessment can be performed in combination with output power and environmental information, thereby improving the accuracy of health status assessment of the solar panel.
