[0036] The processor can be a theoretical power generation calculation module, which calculates the theoretical power generation according to the environmental light intensity, temperature and photovoltaic panel 101 characteristics.

[0037] The basic electrical characteristics of a photovoltaic cell (photovoltaic panel 101) refer to its performance indicators in the electrical aspect, which determine the ability of the photovoltaic cell to convert light energy into electrical energy and affect its power generation efficiency and output characteristics. The following are several electrical characteristics needed in theoretical calculation:

[0038] Open-circuit voltage (Voc): This is the voltage across the cell when no current is flowing through it, representing the maximum voltage of the photovoltaic cell under no load condition.

[0039] Short-circuit current (Isc): When the cell is short-circuited, the current flowing through the cell is the short-circuit current, which is the maximum current that the photovoltaic cell can generate without voltage drop.

[0040] Fill factor (FF): This is a dimensionless parameter that measures the closeness of the actual output power of the photovoltaic cell to the theoretical maximum power. It is the ratio of the actual output power to the product of open-circuit voltage and short-circuit current, multiplied by 100%. A higher fill factor means higher cell efficiency.

[0041] Photoelectric conversion efficiency (η): This is the efficiency of the photovoltaic cell in converting light energy into electrical energy, usually expressed as a percentage, calculated as the ratio of actual output power to incident light power.

[0042] Temperature coefficient: This is the rate at which the performance of the photovoltaic cell (such as open-circuit voltage, short-circuit current and maximum output power) changes with temperature. The temperature coefficient can be positive or negative, depending on the specific characteristic parameter.

[0043] These electrical characteristic parameters are usually listed in the technical specifications of the photovoltaic cell and are measured under standard test conditions (STC), i.e. under the conditions of 1000W / m² light intensity, 25°C ambient temperature and 1 atmosphere pressure.

[0044] Using the characteristic parameters of photovoltaic panel 101 in the power generation detection device (provided in the photovoltaic cell's technical specifications), combined with ambient temperature and light intensity, the theoretical power generation is calculated. The following is the theoretical calculation formula for photovoltaic power generation:

[0053] Photovoltaic cell photoelectric conversion efficiency;

[0054] Temperature of photovoltaic panel 101 (Kelvin, K);

[0055] Reference temperature (Kelvin, K), typically the temperature under STC conditions (25°C or 298K).

[0056] Temperature coefficient.

[0057] The device provided by this utility model is equipped with a dedicated connection device for connecting to the photovoltaic panel 101 under test in order to measure its actual power generation. This connection device is designed with compatibility in mind and can be adapted to various models and specifications of photovoltaic panels 101.

[0058] The connection device has a stable fixing structure to ensure the stability of the photovoltaic panel 101 during the measurement process and prevent external factors such as vibration or wind from interfering with the measurement results.

[0059] The connection device is equipped with a high-precision energy meter located at the output end of the photovoltaic panel 101 inverter, which is used to monitor key parameters such as current, voltage, power and power generation in real time.

[0060] The power generation detection device can be an electricity meter. A high-precision electricity meter is installed at the output of the inverter with a built-in standard photovoltaic panel 101 to accurately measure the actual power generation. The electricity meter records and transmits the data to the processor in real time, providing data for subsequent data processing and power generation assessment and analysis.

[0061] The device proposed in this utility model integrates two core functions, aiming to provide comprehensive and accurate data support and decision-making basis for the optimized design, performance improvement and intelligent management of photovoltaic systems.

[0062] Function 1: Evaluation of Photovoltaic Module Power Generation Status. This function directly measures the actual power generation of the photovoltaic panel 101 by connecting its actual power generation detection module to the panel under test. The measured data is then compared with the theoretical power generation calculated by the theoretical power generation module based on light intensity and temperature, thus accurately evaluating the current operating status of the photovoltaic panel 101. This method not only reflects the power generation performance of the photovoltaic module in real time but also identifies performance deviations, providing valuable operational information for power plant managers.

[0063] In terms of evaluating photovoltaic power generation performance, this device compares the theoretically calculated power generation with the actual measured power generation, and uses the following formula to quantify the efficiency of the photovoltaic system, thereby achieving an objective assessment of the photovoltaic power generation performance:

[0064]

[0065] The calculated theoretical power generation (watts, W);

[0066] The actual measured power generation (watts, W);

[0067] The efficiency of the photovoltaic system is expressed as a percentage.

[0068] Building upon this foundation, the device provided by this invention can utilize statistical methods to deeply analyze the collected data, uncover patterns and relationships within the data, and automatically generate detailed reports covering key performance indicators and analytical results. The reports include efficiency comparisons, performance trends, maintenance and replacement recommendations, and data visualization. This comprehensive information provides photovoltaic power plant managers with a complete set of decision-making support tools, helping them improve the operational efficiency and reliability of photovoltaic power plants based on data. With these reports, photovoltaic power plant managers can obtain scientific basis for maintenance and replacement decisions, ensuring the power plant operates at optimal efficiency, maximizing energy output, and thereby enhancing the overall operational efficiency and stability of the photovoltaic system.

[0069] Function II: Analyzing the impact of environmental factors on the photovoltaic power generation effect. The environmental detection sensor can measure key environmental parameters such as light intensity, temperature, humidity, pressure, and wind speed. These factors affect the surface characteristics of the photovoltaic panel 101, the atmospheric propagation of solar radiation, and the cooling effect of the photovoltaic panel 101, thereby changing the actual power generation of the photovoltaic panel 101. In addition to the measurement of these environmental parameters, the device is equipped with a standard photovoltaic panel 101 to measure the actual power generation under the same environment. By comparing the actual power generation with the theoretical calculation value and introducing the impact coefficient, the impact of these additional environmental factors on the photovoltaic power generation efficiency can be quantified, and the relationship between each environmental factor and the power generation situation can be evaluated.

[0070] The following is the calculation formula of the photovoltaic power generation considering these environmental factors:

[0089] It should be noted that the above evaluation method itself is a prior art scheme, and here it is only to fully explain the working principle of the data acquisition device provided by the utility model.

[0090] The device provided by the utility model can be used for quantitative analysis of the difference between the actual power generation and the theoretical power generation of the photovoltaic panel 101 under different environmental conditions. The theoretical power generation is mainly calculated based on the light intensity and temperature, while the actual power generation is also affected by environmental factors such as humidity, air pressure, and wind speed. By accurately measuring these factors and comparing them with the theoretical power generation, the specific influence of these factors on the photovoltaic power generation efficiency can be revealed. When calculating the influence coefficient K, the control variable method is used to evaluate the influence of wind speed change on power generation during a period of relatively stable humidity and air pressure, so as to determine the wind speed influence coefficient. Combined with comprehensive analysis of multiple time period data samples, the accuracy and reliability of the influence coefficient K are improved, and the influence of environmental factors on the power generation efficiency of the photovoltaic panel 101 is truly reflected. This data-driven method provides accurate environmental influence evaluation for photovoltaic power station design, operation, and maintenance, optimizes system performance and efficiency. By quantifying environmental influence, more effective maintenance plans can be developed to extend the service life of the photovoltaic panel 101 and improve the economic benefits of the photovoltaic power station. Managers can make scientific decisions based on data to optimize energy output, reduce operating costs, and enhance the sustainability and competitiveness of photovoltaic power stations.
