Description

TECHNICAL FIELD

[0001] The present application relates to the field of photovoltaic technology, and particularly relates to a photovoltaic cell panel support control method and device based on temperature and season. BACKGROUND

[0002] In today's society, with the increasing demand for energy and growing concern about environmental issues, solar energy as a clean and renewable energy has received widespread attention. As the core component of solar power generation systems, the power generation efficiency and performance of photovoltaic cell panels play a key role in the overall system benefits.

[0003] Currently, in the application of photovoltaic cell panels, the traditional installation method is usually to fix the cell panels at a certain angle and position. This fixed posture installation method has many limitations. On the one hand, since the position of the sun in the sky changes constantly with factors such as season and time, the fixed posture of the photovoltaic cell panels cannot always receive solar radiation energy at the best angle, resulting in low power generation efficiency, especially during the transition period of different seasons, energy loss is more significant. On the other hand, environmental factors such as light intensity and temperature also have an important impact on the working state of the photovoltaic cell panels. When the light intensity is weak or the environmental temperature is too high, the power generation performance of the cell panels will be inhibited, and the fixed posture cannot adapt to these environmental changes, further reducing the power generation efficiency and the service life of the equipment.

[0004] In addition, existing photovoltaic cell panel support control methods based on temperature and season often only consider a single factor, such as simple adjustment based on the solar elevation angle or light intensity, ignoring the complex influence of multiple environmental factors interacting with each other, making it difficult to achieve precise and dynamic posture adjustment, and unable to meet the needs of high-efficiency and stable operation of photovoltaic systems under different environmental conditions.

Detailed Implementation

[0022] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0023] The following description, with reference to the accompanying drawings, describes a method, apparatus, electronic device, chip, and storage medium for controlling photovoltaic panel supports based on temperature and season.

[0024] Figure 1 This is a schematic diagram of a process for controlling a photovoltaic panel support based on temperature and season, provided as an embodiment of this application.

[0025] As one implementation, the temperature and season-based photovoltaic panel support control method of this application embodiment can be configured in a temperature and season-based photovoltaic panel support control device. The temperature and season-based photovoltaic panel support control device can be applied to any electronic device so that the electronic device can perform the temperature and season-based photovoltaic panel support control function.

[0026] Among them, electronic devices can be any device with computing capabilities, such as mobile terminals, which can be hardware devices with various operating systems, touch screens and / or displays, such as mobile phones, tablets, personal digital assistants, wearable devices, etc.

[0027] As another implementation, the photovoltaic panel support control method based on temperature and season in this application embodiment can also be executed by a chip with processing capabilities. The chip includes an image signal processing chip (ISP), a central processing unit (CPU), an application-specific integrated circuit (ASIC), a digital signal processor (DSP), a field-programmable gate array (FPGA), a system on a chip (SOC), a reduced instruction set computer (RISC), etc., which will not be listed here.

[0028] It should be noted that all data collection operations related to users in this application are conducted with the user's authorization and in strict compliance with relevant laws and regulations such as privacy and security.

[0029] like Figure 1 As shown, the method may include the following steps: Step 101: Collect information on the light intensity, ambient temperature, and season of the environment where the photovoltaic panels are located; Step 102: Based on the preset three-dimensional mapping model of light-temperature-season, calculate the target height, target pitch angle and target horizontal orientation angle of the photovoltaic panel; Step 103: Drive the height adjustment mechanism, pitch angle adjustment mechanism and horizontal rotation mechanism to move so that the photovoltaic panel reaches the target height, target pitch angle and target horizontal orientation angle.

[0030] In this embodiment, light intensity, ambient temperature, and seasonal information are simultaneously collected within the environment where the photovoltaic panel is located. Light intensity reflects the strength of solar radiation, ambient temperature relates to the equipment's operating status, and seasonal information reflects the macroscopic variations in solar altitude angle and sunshine duration. This data is acquired in real time through corresponding sensors, providing a precise basis for subsequent attitude adjustments.

[0031] Based on a pre-defined three-dimensional mapping model of light intensity, temperature, and season, the collected light intensity, ambient temperature, and seasonal information are input and processed by a complex algorithm to derive the target height, pitch angle, and horizontal orientation angle of the photovoltaic panel. This three-dimensional mapping model comprehensively considers the influence of various environmental factors on the optimal attitude of the photovoltaic panel, and can accurately calculate the optimal attitude parameters according to different environmental conditions to maximize the reception of solar radiation energy.

[0032] After obtaining the target attitude parameters, the height adjustment mechanism, pitch angle adjustment mechanism, and horizontal rotation mechanism are driven sequentially. These mechanisms are responsible for adjusting the height, pitch angle (i.e., the angle between the solar panel and the horizontal plane), and horizontal orientation angle of the photovoltaic panel, respectively. Through precise mechanical transmission and control, the photovoltaic panel smoothly and accurately reaches the calculated target height, target pitch angle, and target horizontal orientation angle, thereby achieving dynamic attitude adjustment and improving the power generation performance and operational stability of the photovoltaic panel.

[0033] Optionally, the calculation of the target altitude, target pitch angle, and target horizontal orientation angle includes: Spectral analysis of light intensity is performed, and the target elevation angle is determined based on the ratio of visible light to infrared light. The target height is determined based on the difference between the ambient temperature and the operating temperature of the photovoltaic panel. Determine the target horizontal orientation angle based on the current seasonal trend of solar altitude angle changes.

[0034] In this embodiment, the calculation process for the target altitude, target pitch angle, and target horizontal orientation angle is explained in detail: Target pitch angle determination: Spectral analysis is performed on the collected light intensity data to deeply analyze the spectral characteristics of the light. By calculating the ratio of visible to infrared light intensity, and based on the preset correspondence between this ratio and the pitch angle, the initial pitch angle of the photovoltaic panel is determined. Different wavelengths of light have different effects on the power generation efficiency of photovoltaic cells. The ratio of visible to infrared light reflects the spectral distribution characteristics of solar radiation. Adjusting the pitch angle accordingly can optimize the panel's light energy reception.

[0035] Target Height Determination: By measuring the ambient temperature and comparing it with the operating temperature of the photovoltaic panel, the difference between the two is calculated. Based on a pre-established mapping relationship between temperature difference and height adjustment, the target height of the photovoltaic panel is determined according to this difference. When the ambient temperature is high, appropriately lowering the panel height can reduce heat accumulation; conversely, when the ambient temperature is low, appropriately raising the panel height helps maintain a stable operating temperature, thereby ensuring that the photovoltaic panel maintains good operating condition under different ambient temperatures, improving power generation efficiency and extending service life.

[0036] Target horizontal orientation angle determination: Based on the current season, analyze the changing trend of the solar altitude angle. The solar altitude angle exhibits regular changes in different seasons. By studying its changing trend, combined with the geographical location and installation conditions of the photovoltaic panels, calculate the appropriate target horizontal orientation angle. This angle is determined to ensure that the photovoltaic panels face the sun to the maximum extent throughout the year, fully receiving solar radiation energy and improving overall power generation efficiency.

[0037] In one possible embodiment, the hardware preparation of the system includes: Install a three-degree-of-freedom actuator on the bracket: a) Electric linear actuator (height adjustable, travel 0–60 cm, step 0.5 cm) b) Pitch angle servo motor (-10° ~ +60°, 0.1° step) c) Horizontal rotary servo motor (0° ~ 360°, 0.1° step) Sensor deployment: Illuminance meter (0–150,000 lx, sampling per second) Ambient temperature probe (-40 °C ~ +85 °C, sampling per second) GPS / BeiDou module (obtains accurate date, time, latitude and longitude for seasonal determination) Control unit: Industrial-grade MCU + 4G gateway, supporting OTA upgrades.

[0038] Optionally, the step of performing spectral analysis on the illumination intensity and determining the target elevation angle based on the ratio of visible light to infrared light includes: Determine the intensity ratio of the visible light to the infrared light; The light intensity ratio is collected through a preset time window, and the power spectrum corresponding to the light intensity ratio within the time window is determined. The pitch angle correction amount is determined based on the light intensity ratio and the spectral characteristics corresponding to the power spectrum, and the target pitch angle is determined based on the pitch angle correction amount and the pitch angle reference amount.

[0039] In this embodiment, the step of performing spectral analysis on light intensity to determine the target pitch angle is further refined and supplemented: Light intensity ratio determination: Using a high-precision spectral analysis instrument, the collected light intensity data is spectrally decomposed to accurately distinguish and measure the intensity of visible and infrared light, thereby calculating the light intensity ratio between the two. This light intensity ratio is a crucial basis for subsequently determining the pitch angle correction, and its accuracy directly affects the precision of photovoltaic panel support control based on temperature and season.

[0040] Power Spectrum Acquisition and Analysis: A preset time window, such as 10 minutes or 30 minutes, is set, and the intensity ratio data of visible and infrared light is continuously acquired within this time window. Power spectrum analysis is performed on this data to determine the power spectrum corresponding to the intensity ratio within the time window. The power spectrum reflects the energy distribution characteristics of the intensity ratio at different frequencies, revealing the regularity and stability of light intensity changes over time, providing crucial information for subsequent pitch angle correction calculations.

[0041] Pitch angle correction determination: Taking into account the spectral characteristics corresponding to the light intensity ratio and power spectrum, the pitch angle correction is determined through a preset algorithm and logical judgment. Based on this correction, the initial pitch angle is adjusted to obtain the target pitch angle. This process fully considers the spectral and temporal characteristics of light intensity, making the pitch angle adjustment of photovoltaic panels more precise and accurate, better adapting to complex and changing lighting environments, and improving power generation efficiency and stability.

[0042] In one possible embodiment, a spectral sensor is used to detect light intensity, wherein The dual-channel digital spectral probe includes: Channel A: 400–700 nm (visible light, VIS); Channel B: 700–1100 nm (near-infrared, NIR). Sampling frequency is 1 Hz, with 16-bit quantization. 2 C output.

[0043] Read the light intensities V and N from both the VIS and NIR channels per second. Calculate the instantaneous ratio R = V / (V+N) and normalize it to 0–1.

[0044] The light intensity ratio is averaged within a time window to obtain the average light intensity ratio R̄, thus suppressing high-frequency noise.

[0045] R̄ is cached into a circular queue of length 256 (≈4 min of data) for the next FFT step.

[0046] Perform FFT on the 256-point R̄ sequence to obtain the power spectrum P(k).

[0047] Extracting power in the main frequency bands: Low frequency band (k = 0–3): Clouds, slowly changing atmosphere, denoted as P_low; Mid-frequency band (k = 4–15): transient shadowing and scattering, denoted as P_mid; High frequency band (k = 16–127): Noise, discard.

[0048] Define the spectral characteristic S = P_mid / (P_low + P_mid). A larger S indicates a higher proportion of scattered / infrared light in sunlight; a smaller S indicates that direct visible light is dominant.

[0049] Optionally, determining the pitch angle correction based on the light intensity ratio and the spectral characteristics corresponding to the power spectrum includes: In response to the light intensity ratio being greater than or equal to a first threshold and the spectral characteristics being lower than a second threshold, the pitch angle correction is determined to be 0. In response to the light intensity ratio being less than the first threshold and greater than or equal to the third threshold, and the spectral characteristics being greater than or equal to the second threshold and less than the fourth threshold, the pitch angle correction amount is determined to be a preset first correction amount; In response to the light intensity ratio being less than the first threshold and the third threshold, and the spectral characteristics being greater than or equal to the fourth threshold, the pitch angle correction amount is determined to be a preset second correction amount; the second correction amount is greater than the first correction amount.

[0050] In this embodiment, the part that determines the pitch angle correction based on the spectral characteristics corresponding to the light intensity ratio and power spectrum further refines and clarifies the processing logic under different conditions: When the ratio of visible light to infrared light intensity is detected to be greater than or equal to the first threshold, and the spectral characteristics corresponding to the power spectrum are lower than the second threshold, it is determined that the current lighting environment is relatively stable and dominated by visible light, so there is no need to correct the pitch angle. Therefore, the pitch angle correction is set to 0. At this time, the photovoltaic panel can maintain a good power generation state by maintaining its original pitch angle, avoiding unnecessary adjustment operations and improving the stability and reliability of the system.

[0051] When the light intensity ratio falls between the third and first thresholds (i.e., less than the first threshold and greater than or equal to the third threshold), and the spectral characteristics fall between the second and fourth thresholds (i.e., greater than or equal to the second threshold and less than the fourth threshold), it indicates a change in the lighting environment and that the ratio of visible to infrared light is in an intermediate state. In this case, the pitch angle correction is determined to be the preset first correction value. This first correction value, determined through extensive experiments and data analysis, effectively addresses the power generation needs under these specific lighting conditions. By adjusting the pitch angle, the photovoltaic panels can better receive solar radiation, thereby improving power generation efficiency.

[0052] If the light intensity ratio is less than the third threshold and the spectral characteristics are greater than or equal to the fourth threshold, it indicates that the lighting environment is dominated by infrared light and the light intensity changes drastically. In this case, the pitch angle correction is determined to be the preset second correction, which is greater than the first correction. The larger correction aims to ensure that the photovoltaic panels can still optimize their posture under these unfavorable lighting conditions, reduce energy loss, and guarantee the normal operation and power generation efficiency of the power generation system.

[0053] In one possible embodiment, the reference pitch angle θ_base is calculated from the solar altitude angle α: θ_base = 90°–α.

[0054] If R̄ ≥ 0.65 and S ≤ 0.30 (direct visible light intensity): Δθ = 0°, maintaining θ_base.

[0055] If 0.45 ≤ R̄ < 0.65 or 0.30 < S < 0.50 (mixed light): Δθ = +3° (slightly towards the sky dome to enhance scattered light collection).

[0056] If R̄ < 0.45 or S ≥ 0.50 (dominated by infrared / scattered light): Δθ = +8° (larger elevation angle to reduce ground reflection loss and prioritize NIR absorption).

[0057] The target pitch angle θ_target = θ_base + Δθ, restricted within the 5°–55° safety range.

[0058] Optionally, determining the target height based on the difference between the ambient temperature and the operating temperature of the photovoltaic panel includes any of the following: In response to the ambient temperature being higher than the operating temperature of the photovoltaic panel, calculating an elevation value based on the difference, and determining the target height according to the elevation value; In response to the ambient temperature being less than or equal to the operating temperature of the photovoltaic panel, maintaining the current target height.

[0059] In this embodiment, when it is monitored that the ambient temperature is higher than the operating temperature of the photovoltaic panel, the difference between the two is calculated. According to the preset mapping relationship between the temperature difference and height adjustment, the corresponding elevation value is calculated. Based on this elevation value, the target height of the photovoltaic panel is determined, and the height adjustment mechanism is driven to raise the panel to the target height. Raising the panel helps increase air circulation, remove excess heat, prevent the panel from degrading in performance due to overheating, ensure its stable operation in a high-temperature environment, and maintain the power generation efficiency.

[0060] If the ambient temperature is less than or equal to the operating temperature of the photovoltaic panel, the current target height is maintained unchanged. At this time, the photovoltaic panel is in a relatively suitable operating temperature range and no height adjustment is required. Through this conditional judgment and corresponding processing, precise control of the height of the photovoltaic panel is achieved, enabling it to maintain the best operating state under different ambient temperature conditions and extending the service life of the equipment.

[0061] In one possible embodiment, a temperature-efficiency correction table is established: The empirical formula η(T) = η25[1 - β(T - 25)], where β ≈ 0.0045 / °C and T is the ambient temperature.

[0062] When the ambient temperature is >45°C, the height of the bracket is increased by 0.5cm for every 1°C increase to increase ventilation at the back.

[0063] Optionally, determining the target horizontal orientation angle based on the current seasonal trend of solar altitude angle variation includes: The rate of change at each point in time is obtained based on the changing trend of the solar altitude angle in the current season. Determine the azimuth sensitivity parameters based on the noon value of the solar altitude angle in the current season; The azimuth correction value is determined based on the azimuth sensitivity parameter and the rate of change. The target horizontal orientation angle is determined based on the azimuth correction value and the base azimuth.

[0064] In this embodiment, the rate of change is obtained by deeply analyzing the changing trend of the solar altitude angle in the current season. Through establishing a mathematical model and utilizing astronomical data, the rate of change of the solar altitude angle at each point in time is calculated. This rate of change reflects the speed at which the sun's trajectory in the sky changes over time, providing crucial time-dimensional information for subsequent calculations of the target horizontal orientation angle. This helps photovoltaic panels track the sun's position in real time, improving power generation efficiency.

[0065] Azimuth sensitivity parameter determination: Based on the noon value of the solar altitude angle for the current season, combined with the geographical location and installation conditions of the photovoltaic panels, the azimuth sensitivity parameter is determined using a preset algorithm and table lookup methods. This parameter reflects the sensitivity of the noon solar altitude angle to azimuth adjustment, and can quantitatively represent the extent to which the azimuth angle of the photovoltaic panels needs to be adjusted to adapt to changes in the solar altitude angle under different seasons and geographical locations, providing a basis for accurately calculating the azimuth correction value.

[0066] Azimuth correction calculation: Taking into account the azimuth sensitivity parameter and the rate of change of solar altitude angle at various time points, the azimuth correction value is calculated by establishing a mathematical relationship model. This correction value reflects the magnitude and direction of the azimuth angle adjustment required for photovoltaic panels under the current seasonal conditions to ensure that they always face the sun and receive solar radiation energy to the maximum extent.

[0067] Target horizontal orientation angle determination: By combining the calculated azimuth correction value with the preset base azimuth angle, and through operations such as coordinate transformation and angle calculation, the target horizontal orientation angle of the photovoltaic panel is finally determined. This angle determination fully considers the patterns and characteristics of seasonal changes in solar altitude angle, enabling the photovoltaic panel to accurately track the sun's position at different times of the year, thus improving the working efficiency and overall performance of the power generation system.

[0068] In one possible implementation, the current date D (cumulative day 1–365) is read using GPS / RTC.

[0069] Seasonal division: Spring: D ∈ [60,151]; Summer: D ∈ [152,243]; Autumn: D ∈ [244,334]; Winter: D ∈ [335,365]∪[1,59].

[0070] Calculate the sun's trajectory for the day For the local latitude φ and the day D, the NREL SPA algorithm is used to generate a 24-hour solar altitude angle α(t) sequence with a step size of 10 min.

[0071] Calculate the daily maximum altitude angle α_max (noon value) and the sunrise-sunrise and sunset times t_sunrise and t_sunset.

[0072] Extracting the "trend of change" feature, we define the slope function k(t) = dα / dt, and approximate it using the difference method: k(t) = [α(t+Δt) – α(t–Δt)] / (2Δt), Δt = 30 min.

[0073] Divide the day into four periods: Morning rising phase (t_sunrise → t_p, k>0 and α<α_max); noon plateau phase (t_p ± 1 h, |k|≈0); afternoon falling phase (t_p → t_sunset, k<0); nighttime phase (no sun).

[0074] Let the maximum rate of ascent be k_up = max(k) and the maximum rate of descent be k_down = min(k).

[0075] Seasonal correction factor Calculate the α_max curve for the whole year and obtain the average values ​​for the four seasons: ᾱ_spring, ᾱ_summer, ᾱ_autumn, ᾱ_winter.

[0076] 4.2 Calculate the seasonal weight W_season = ᾱ_season / ᾱ_summer, used to adjust the azimuth sensitivity: Summer W=1 (most sensitive) Spring / Autumn W≈0.9 Winter W≈0.75 Formula for the horizontal orientation angle of the target (φ_target): φ_target = γ(t) + Δφ_trend The base azimuth angle φ_base is taken from the solar azimuth angle γ(t).

[0077] Introducing "Trend Correction" Δφ_trend: Δφ_trend = 0.5·k(t)·W_season (unit: °, k is ° / h) k>0 (morning) → Δφ_trend is negative, so it swings slightly eastward in advance to capture direct sunlight earlier.

[0078] k<0 (afternoon) → Δφ_trend is positive, and the lag causes a slight westward swing, extending the capture time.

[0079] k≈0 (noon) → Δφ_trend = 0, keep γ(t).

[0080] Optionally, determining the azimuth sensitivity parameter based on the noon value of the solar altitude angle in the current season includes: The noon values ​​are calculated throughout the year to obtain the average noon values ​​for each of the four seasons; The ratio of the average noon value in each season to the average noon value in summer is used as the azimuth sensitivity parameter.

[0081] In this embodiment, the noon value statistics and analysis involve collecting noon solar altitude angle data for the entire year and categorizing them according to season. Statistical analysis methods are then used to calculate the average noon value for each of the four seasons (spring, summer, autumn, and winter). This process involves processing a large amount of astronomical and meteorological data, requiring the use of specialized data analysis tools and algorithms to ensure the accuracy and representativeness of the obtained average noon values ​​for each season.

[0082] Azimuth sensitivity parameter calculation: The average noon value for each season is compared with the average noon value for summer, and their proportional relationship is calculated. This proportion is used as the azimuth sensitivity parameter. Summer solar altitude angles are relatively large, making their noon values ​​highly valuable for reference. By comparing the average noon values ​​with those of other seasons, the resulting azimuth sensitivity parameter reflects the relative impact of changes in solar altitude angle on azimuth adjustment in different seasons. This provides a scientific basis for accurately calculating azimuth correction values, ensuring that photovoltaic panels can accurately adjust their orientation in different seasons to achieve optimal power generation.

[0083] To achieve the above embodiments, this application also proposes a photovoltaic panel support control device based on temperature and season.

[0085] like Figure 2As shown, the device may include: The data acquisition module 210 is used to collect information on the light intensity, ambient temperature, and season of the environment where the photovoltaic panels are located. Analysis module 220 is used to calculate the target height, target pitch angle and target horizontal orientation angle of the photovoltaic panel based on a preset three-dimensional mapping model of light-temperature-season. The adjustment module 230 is used to drive the height adjustment mechanism, the pitch angle adjustment mechanism and the horizontal rotation mechanism to move, so that the photovoltaic panel reaches the target height, the target pitch angle and the target horizontal orientation angle.
