[0004] Solar photovoltaic (PV) power generation systems utilize the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. They can operate independently or be connected to the grid. Independent PV systems require batteries for energy storage and are mainly used in remote and sparsely populated areas without power grids; the overall system cost is very high. In areas with a public power grid, PV systems are connected to the grid, eliminating the need for batteries. This not only significantly reduces costs but also provides higher power generation efficiency and better environmental performance. Photovoltaic panels are devices that generate direct current (DC) electricity when exposed to sunlight. With the advancement of the new energy trend, PV power generation is no longer unfamiliar and is gradually entering people's lives.

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0044] This application provides a solar photovoltaic panel environmental simulation system, as shown in Figures 1 and 2, including an environmental simulation module, an environmental control module, and an electrical control module. The environmental simulation module includes an environmental simulation box 1 and a photovoltaic positioning unit 11 disposed within the environmental simulation box 1, which is used to position multiple photovoltaic panels of different sizes. The environmental control module includes a unit box 2 and a natural wind simulation unit 21, a temperature simulation unit 22, and a drying simulation unit 23 disposed within the unit box 2. An air duct 24 is provided within the unit box 2. The temperature simulation unit 22 and the drying simulation unit 23 are connected to the natural wind simulation unit 21 through the air duct 24, and the natural wind simulation unit 21 is connected to the environmental simulation box 1 through the air duct 24. The electrical control module includes an electrical control box 3, a cooling unit 31 and a humidity simulation unit 32 disposed within the electrical control box 3, and a main control unit 33 disposed on the outer wall of the environmental simulation box 1. Humidity simulation unit 32 is connected to natural wind simulation unit 21 via air duct 24. Cooling unit 31 is connected to natural wind simulation unit 21 via heat exchange. Main control unit 33 is electrically connected to natural wind simulation unit 21, humidity simulation unit 32, temperature simulation unit 22, drying simulation unit 23, and cooling unit 31. The environmental simulation box 1, unit box 2, and electrical control box 3 are separate units, and the environmental simulation box 1 and unit box 2, as well as the unit box 2 and electrical control box 3, are independently assembled.

[0045] By implementing the above-described embodiment of the solar photovoltaic panel environmental simulation system, controlling the natural wind simulation unit 21, temperature simulation unit 22, drying simulation unit 23, and cooling unit 31, various complex environmental conditions can be simulated, including natural wind environments, high-temperature environments, humidity environments, and low-temperature environments. This allows for a comprehensive evaluation of the photovoltaic panel's performance in various practical application environments. Furthermore, it enables rapid setting and modification of environmental conditions, improving testing efficiency and allowing for the completion of photovoltaic panel testing under different environmental conditions in a shorter time, saving testing time and resources. This facilitates accurate evaluation of the photovoltaic panel's power generation efficiency under different temperature and humidity conditions, helps understand the performance change trends of the photovoltaic panel, and provides a basis for the maintenance and optimization of the photovoltaic system.

[0046] Optionally, as shown in Figure 3, the photovoltaic positioning unit 11 includes a support assembly and a positioning component disposed on the support assembly. The support assembly includes a vertical frame 111 and a plurality of horizontal beams 112 arranged vertically on the vertical frame 111. The positioning component includes a plurality of positioning elements 113 disposed on the horizontal beams 112 along the length direction of the horizontal beams 112. The positioning elements 113 are provided with slots corresponding to the thickness of the photovoltaic panel, and the slots on the plurality of positioning elements 113 are of different sizes.

[0047] Through the implementation of the above-described solar photovoltaic panel environmental simulation system embodiment, the photovoltaic positioning unit 11 can adapt to photovoltaic panels of different thicknesses and sizes, that is, by utilizing the different sizes of the slots on the multiple positioning members 113, the installation requirements of different photovoltaic panels can be met. By using the slots, accurate installation of the photovoltaic panels on the support assembly can be ensured, reducing performance loss caused by inaccurate installation. Simultaneously, the slot design of the positioning member 113 allows for the rapid installation or replacement of photovoltaic panels, which is particularly useful in situations requiring frequent replacement of photovoltaic panels, such as testing or maintenance. Since the positioning member 113 is arranged along the length of the crossbeam 112, multiple photovoltaic panels can be placed side-by-side on the vertical frame 111 for simultaneous testing of photovoltaic panels of different sizes.

[0048] Optionally, the support assembly also includes a horizontally arranged base plate 114. A vertical frame 111 is disposed on one side of the base plate 114, and connecting diagonal rods 115 are provided on both sides of the vertical frame 111. The end of the connecting diagonal rod 115 away from the vertical frame 111 is connected to the corresponding side of the base plate 114, so that the connecting diagonal rod 115, the base plate 114, and the vertical frame 111 form a triangular frame.

[0049] By implementing the above-described embodiment of the solar photovoltaic panel environmental simulation system, the triangular frame structure formed by the connecting diagonal rod 115, the substrate 114, and the vertical frame 111 can improve the stability of the connection between the entire substrate 114 and the vertical frame 111, so that multiple photovoltaic panels can be placed and supported on the vertical frame 111 at the same time.

[0050] Optionally, a groove 1141 corresponding to the thickness of the photovoltaic panel is provided on the top surface of the substrate 114, so that the photovoltaic panel slides into the groove 1141 and is positioned on the substrate 114. Both ends of the groove 1141 are open, a water receiving tray is provided at the bottom of the environmental simulation box 1, and a drain outlet communicating with the water receiving tray is provided at the bottom of the environmental simulation box 1.

[0051] Through the implementation of the above-described embodiment of the solar photovoltaic panel environmental simulation system, the sliding groove 1141 provided on the top surface of the substrate 114 allows the photovoltaic panel to be easily slid into and positioned on the substrate 114, simplifying the installation and adjustment process of the photovoltaic panel and enabling it to adapt to photovoltaic panels of different thicknesses and sizes, thus improving the system's versatility and flexibility. Simultaneously, since the photovoltaic panel can slide along the sliding groove 1141, it can be easily removed and replaced during maintenance, facilitating cleaning and repair. Furthermore, the water collection tray ensures that accumulated water in the environmental simulation chamber 1 can be drained promptly when simulating a humidity environment, preventing damage to the photovoltaic panel and internal system components.

[0052] Optionally, as shown in Figures 2 and 4, the natural wind simulation unit 21 includes a circulating motor 211 disposed on the top outside of the unit housing 2, and a circulating air blower 212 disposed on the top inside of the unit housing 2. The drive end of the circulating motor 211 is connected to the drive input end of the circulating air blower 212, and the air outlet of the circulating air blower 212 is connected to the interior of the environmental simulation box 1.

[0053] Through the implementation of the above-described embodiment of the solar photovoltaic panel environmental simulation system, the combination of the circulating motor 211 and the circulating blower 212 ensures uniform wind speed distribution inside the environmental simulation chamber 1. By adjusting the speed of the circulating motor 211, the simulated wind speed can be changed, thereby conducting tests under different wind speed conditions, which helps to evaluate the system's performance under different wind speeds. Simultaneously, by simulating a natural wind environment, potential wind load problems with the photovoltaic panels can be identified and addressed in advance, thus extending the lifespan of the photovoltaic panels.

[0054] Optionally, multiple air outlets 116 are provided at the bottom of the walls of the environmental simulation box 1 and the unit box 2, which are adjacent to each other. The air outlets 116 are connected to the interior of the unit box 2, and the air outlets 116 are connected to the air inlet of the circulating blower 212 through the air duct 24.

[0055] Through the implementation of the above-described embodiment of the solar photovoltaic panel environmental simulation system, the air outlet 116 provided between the environmental simulation chamber 1 and the unit chamber 2 allows air to flow from the environmental simulation chamber 1 to the unit chamber 2 and enter the air duct 24, where it is drawn in by the circulating blower 212. This creates a continuous air circulation between the environmental simulation chamber 1 and the unit chamber 2, simulating the required environmental conditions inside the environmental simulation chamber 1. By recycling the air, the consumption of external air is reduced, thereby saving energy and providing controllable and repeatable natural wind simulation environmental conditions, which helps improve the accuracy and reliability of the test.

[0056] Optionally, referring to Figure 5, the humidity simulation unit 32 includes a humidifier 321 installed in the electrical control box 3 and a humidity sensor installed in the environmental simulation box 1. The humidifier 321 is connected to the air duct 24. The temperature simulation unit 22 includes a heater 221 installed in the unit box 2 and a temperature sensor installed in the environmental simulation box 1. The heater 221 is installed on the air duct 24. The drying simulation unit 23 includes an evaporator 231 installed in the unit box 2 and a moisture sensor installed in the environmental simulation box 1. The evaporator 231 is connected to the air duct 24.

[0057] Through the implementation of the above-described embodiment of the solar photovoltaic panel environmental simulation system, the humidity, temperature, and dryness within the environmental simulation chamber 1 can be precisely controlled using the humidifier 321, heater 221, and evaporator 231 to meet various testing requirements. For example, the humidity simulation unit 32 provides a controllable humidity environment, which helps evaluate the performance of the photovoltaic panel under humid conditions and prevents corrosion or other damage caused by humidity changes; the temperature simulation unit 22 allows testing the reaction and performance of the photovoltaic panel at different temperatures to evaluate the thermal stability and mechanical properties of the material; the dryness simulation unit 23 is used to simulate dry conditions and test the performance of the photovoltaic panel in a dry environment to evaluate the product's durability and weather resistance. Thus, by simulating various climatic conditions, including high temperature, high humidity, low temperature, and dry conditions, accurate environmental simulation contributes to the reliability of test results and reduces testing workload and long-term operating costs.

[0058] Optionally, the internal structure of the electrical control box 3 is divided into independent refrigeration chamber and compression chamber. The refrigeration unit 31 includes a condenser 311 and a heat exchanger 312 disposed in the refrigeration chamber, and a compressor 313 disposed in the compression chamber. The condenser 311 is connected to the heat exchanger 312 and is used to cool the heat exchange medium inside the heat exchanger 312. The compressor 313 is provided with an air inlet and an air outlet, and the heat exchanger 312 is connected to the compressor 313 to cool the compressed air inside the compressor 313. The air outlet of the compressor 313 is connected to the air duct 24. The inner wall of the refrigeration chamber is provided with a heat insulation cotton layer, and the bottom of the compressor 313 is provided with a shock-absorbing spring pad.

[0059] Through the implementation of the above-described solar photovoltaic panel environmental simulation system embodiment, the refrigeration chamber and the compression chamber are separated to allow for individual control and optimization of each chamber. The combined use of the condenser 311 and heat exchanger 312 effectively cools the heat exchange medium within the heat exchanger 312, improving refrigeration efficiency. Heat exchange between the compressor 313 and the heat exchanger 312 cools the compressed air within the compressor 313, allowing it to blow low-temperature air into the environmental simulation chamber 1 through the air duct 24 to simulate a low-temperature environment. Furthermore, the use of an insulation layer on the inner wall of the refrigeration chamber effectively blocks external heat from entering, reducing heat conduction and thus lowering the energy consumption of the refrigeration unit 31, improving refrigeration efficiency, and reducing the workload of the compressor 313. Simultaneously, the use of shock-absorbing spring pads at the bottom of the compressor 313 effectively absorbs vibrations generated during operation, reducing the impact on the equipment itself and the surrounding environment.

[0060] Optionally, as shown in Figures 2 and 6, the environmental simulation module further includes a moisture-proof lighting unit 4 disposed above the environmental simulation chamber 1. The moisture-proof lighting unit 4 includes a position adjustment assembly and a moisture-proof lamp disposed on the position adjustment assembly. The position adjustment assembly includes a top main frame 41, a top transverse frame 42, a transverse drive push rod, a top lifting frame 43, a lifting drive push rod 44, and a lampshade 45. The top transverse frame 42 is slidably disposed on the top main frame 41, and the transverse drive push rod is disposed on one side of the top transverse frame 42, with its pushing end connected to the top transverse frame 42. The top lifting frame 43 is laid flat on the top transverse frame 42, and the lifting drive push rod 44 is disposed on the top transverse frame 42, with its push rod end connected to the top lifting frame 43. Multiple lampshades 45 are disposed on the top lifting frame 43, and each lampshade 45 contains a moisture-proof lamp. The top wall of the environmental simulation chamber 1 is provided with a guide hole corresponding to the lampshade 45, and the top outer wall of the environmental simulation chamber 1 is provided with a receiving groove corresponding to the lampshade 45 on one side of the guide hole.

[0061] Through the implementation of the above-described solar photovoltaic panel environmental simulation system embodiment, the lifting drive push rod 44 drives the top lifting frame 43 to rise and fall, which simultaneously drives multiple lamp covers 45 on the top lifting frame 43 to rise and fall, allowing the lamp covers 45 to be placed into or lifted out of the environmental simulation box 1 along the guide holes. That is, when the environmental simulation box 1 is in a humid or high-humidity environment, the lamp covers 45 are controlled to be placed into the environmental simulation box 1 along the guide holes, so that the moisture-proof lamps inside the lamp covers 45 provide sufficient illumination, ensuring that the operator can clearly observe the environment inside the environmental simulation box 1 under humid conditions.

[0062] Conversely, after the environmental simulation ends, the top lifting frame 43 is raised by the lifting drive push rod 44, causing the lampshade 45 to be lifted away from the environmental simulation box 1 along the guide hole. Once the lampshade 45 is completely lifted away from the guide hole, the top horizontal moving frame 42 is slid on the top main frame 41 by the horizontal moving drive push rod, simultaneously moving the top lifting frame 43 horizontally until the lampshade 45 is moved above the receiving slot. Then, the top lifting frame 43 is lowered by the lifting drive push rod 44, allowing multiple lampshades 45 on the top lifting frame 43 to be placed into their corresponding receiving slots. This allows for the placement of the moisture-proof lamps when the solar photovoltaic panel environmental simulation system is shut down and unloaded, preventing the moisture-proof lamps from being continuously affected by the external environment and thus extending their service life.

[0063] This application also discloses an environmental simulation method, employing the aforementioned solar photovoltaic panel environmental simulation system, comprising:

[0064] Prepare several photovoltaic panels to be tested, place the photovoltaic panels to be tested on the photovoltaic positioning unit 11 in the environmental simulation box 1, and adjust the position and angle of the photovoltaic panels;

[0067] The main control unit 33 starts the cooling unit 31 and blows cooled natural air into the environmental simulation box 1 through the air duct 24 to simulate a low-temperature environment;

[0068] Based on the testing requirements, at least one simulated environment is set up, including natural wind environment, high temperature environment, humidity environment and low temperature environment, and the power generation data and environmental parameters of the photovoltaic panel are collected through corresponding sensors.
