Description

Technical Field

[0001] This invention relates to the field of light testing technology, and more particularly to a solar simulator for light aging testing. Background Technology

[0002] During the solar simulator test of photovoltaic modules, the solar simulator can accelerate the simulation of the state of the modules after long-term exposure to sunlight (especially ultraviolet rays and heat) outdoors under controlled laboratory conditions, thereby exploring the aging of photovoltaic modules.

[0003] Currently, when conducting photoaging tests on photovoltaic (PV) panels, solar simulators are typically used to subject the panels to prolonged, continuous irradiation from different angles. However, during actual installation and use, PV panels experience various weather changes, which often occur synchronously with changes in sunlight exposure. Consequently, environmental changes such as temperature and humidity also occur simultaneously. Conventional laboratory photoaging tests struggle to replicate these synchronous changes in actual PV panel usage, resulting in limited test data. Furthermore, complex temperature and weather conditions are difficult to coordinate comprehensively, and the environmental impact varies across different installation areas. In coastal mudflats or mountainous regions, PV panels installed in extremely high-temperature environments generate heat waves (rising hot air currents) from the ground. These rising hot air currents envelop the PV panels, creating a localized "thermal barrier" or "thermal environment." This rising hot air hinders the PV panels from dissipating heat through natural convection and radiation. Under these photoaging test conditions, the performance requirements for PV panels are relatively high. Therefore, a solar simulator for photoaging testing is proposed. Summary of the Invention

A temperature simulation chamber is disposed on the outside of the test photovoltaic panel. The temperature simulation chamber is rotatably connected to a simulation cover via an electric hinge. A weather simulation mechanism is disposed on the end face of the simulation cover. Photometric components are disposed on both sides of the weather simulation mechanism. The daylighting system is connected to an electromagnetic base via a cable. The electromagnetic base is connected to a limit slide rail.

[0009] Preferably, the weather simulation mechanism includes a connecting pipe fixed to the top of the simulation cover, and multiple spray heads are fixedly connected to the bottom of the simulation cover.

[0010] Preferably, a linkage adjustment box is fixedly connected to the side wall of the test bench, the inner side wall of the linkage adjustment box is fixedly connected to the limiting slide rail, and the magnetic slide seat is slidably connected to the limiting slide rail.

[0012] Preferably, the two sets of U-shaped docking plates located on one side of the temperature control seat are respectively positioned below the front and above the rear of the adjusting rack. The temperature control seat is connected to a three-way slide rail via three parallel guide plates, and the three-way slide rail is slidably connected to the U-shaped docking plate at the rear.

[0013] Preferably, the three sets of U-shaped docking plates located on one side of the weather control unit are respectively positioned below the front, directly below, and above the rear of the adjusting rack.

The weather control unit is connected to a double slide rail via two parallel guide plates. The double slide rail is slidably connected to the U-shaped docking plate at the rear.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This solution, through the setting of the amplification component, can use the combination of laser sensor and amplified reflective plate to detect the slight warping of the test photovoltaic panel, and monitor the correlation between the warping changes of the test photovoltaic panel and its electrical test data under different simulated working conditions.

[0022] Example, refer to Figures 1 to 9A solar simulator for photoaging testing includes a test platform 1 and a universal adjustment bracket 2 for adjusting the illumination angle of a solar lighting system 3. A test photovoltaic panel 6 is mounted on the top of the test platform 1 via the bracket. Magnification components are mounted on both sides of the test photovoltaic panel 6. A temperature simulation box 4 is set on the outside of the test photovoltaic panel 6. The temperature simulation box 4 is connected to a simulation cover 7 via an electric hinge. A weather simulation mechanism is set on the end face of the simulation cover 7. Photometric components are set on both sides of the weather simulation mechanism. Furthermore, the top of the test platform 1 is rotatably connected to the daylighting system 3 via a universal adjustment bracket 2. A heat flow simulation chamber 5 is provided on the test platform 1. The heat flow simulation chamber 5 is installed with the test photovoltaic panel 6 via a bracket. The amplification component includes two vertical clamps 12 fixed to the upper and lower surfaces of the test photovoltaic panel 6. The two vertical clamps 12 are fixedly connected to a vertical seat 11. An amplification reflection plate 13 is fixedly connected to the outer wall of the vertical seat 11. The light measurement component includes a laser sensor 9 fixed to the bottom of the simulation cover 7. A sensing receiving plate 10 is provided on the outward side of the laser sensor 9. The laser sensor 9 and the amplification reflection plate 13 are located on the same vertical line. The weather simulation mechanism includes a connecting pipe fixed to the top of the simulation cover 7. Multiple spray heads 8 are fixedly connected to the bottom of the simulation cover 7. Among them, the temperature simulation chamber 4 is used to simulate and test the ambient temperature of the photovoltaic panel 6 under different weather conditions. The weather simulation agency can use existing technologies such as fogging, snowmaking and water spraying to simulate and test various weather conditions for the photovoltaic panel 6, simulate various states and control hot and cold temperatures. These are existing technical means and will not be described in detail later. It should be noted that: due to the temperature changes in the simulated day-night cycle, the test photovoltaic panel 6 will warp to a certain extent, thus affecting the light aging resistance of the test photovoltaic panel 6. Therefore, during the test, two vertical clamps 12 are respectively clamped on the upper and lower surfaces of the test photovoltaic panel 6, and the vertical seat 11 is made to fit against the test photovoltaic panel 6, so that the vertical seat 11 and the edge of the test photovoltaic panel 6 are always on the same plane. Thus, the amplified reflective plate 13 is on the same plane as the edge of the test photovoltaic panel 6. When the test photovoltaic panel 6 warps on both sides during the light aging test, the amplified reflective plate 13 will deflect upward at a certain angle. Since the amplified reflective plate 13 extends outward, the small warping angle change of the test photovoltaic panel 6 will be amplified. The light projected by the laser sensor 9 onto the amplified reflective plate 13 will change due to the deflection, causing the reflection angle of the light to change, so that the sensing receiving plate 10 will sense the change in the landing point of the reflected light. The advantages mentioned above are as follows: by using the combination of laser sensor 9 and amplified reflective plate 13, the slight warping of the test photovoltaic panel 6 can be detected, and the correlation between the warping changes of the test photovoltaic panel 6 and its electrical test data under different simulated working conditions can be monitored at all times, making the overall light aging test data more complete. The daylighting system 3 is connected to an electromagnetic base 16 via a cable. The electromagnetic base 16 is connected to a limit slide rail 15. The inner end face of the limit slide rail 15 is connected to a magnetic slide 18 via a reset telescopic rod 17. Both sides of the magnetic slide 18 are connected to adapter components via right-angle seats. One adapter component is connected to a temperature control seat 24 via two sets of U-shaped docking plates 22. The other adapter component is connected to a weather control seat 26 via three sets of U-shaped docking plates 22. Furthermore, a linkage adjustment box 14 is fixedly connected to the side wall of the test bench 1. The inner side wall of the linkage adjustment box 14 is fixedly connected to the limiting slide rail 15. The magnetic slide seat 18 is slidably connected to the limiting slide rail 15. The adapter assembly includes an adjustment rack 20 fixed to the inner wall of the linkage adjustment box 14. An adjustment gear 19 is rotatably connected to the right-angle seat through a pin. The adjustment gear 19 meshes with the adjustment rack 20. An elastic adapter guide rod 21 is fixedly connected to the adjustment gear 19 through a pin. Two sets of U-shaped docking plates 22 located on one side of the temperature control seat 24 are respectively set on the adjustment rack 20. Below and above the rear of the 0, the temperature control base 24 is connected to a three-way slide rail 23 via three parallel guide plates. The three-way slide rail 23 is slidably connected to the U-shaped docking plate 22 at the rear. The three sets of U-shaped docking plates 22 located on one side of the weather control base 26 are respectively set below the front, directly below, and above the rear of the adjusting rack 20. The U-shaped docking plates 22 located below the front and directly below the adjusting rack 20 are set at right angles to each other. The weather control base 26 is connected to a double slide rail 25 via two parallel guide plates. The double slide rail 25 is slidably connected to the U-shaped docking plate 22 at the rear. It should be noted that when simulating ultra-low temperature environments, a small current is input to the daylighting system 3, and a small current is also input to the corresponding electromagnetic base 16, causing the electromagnetic base 16 to generate a small magnetism. This, in turn, generates a small magnetic repulsion force on the magnetic slide base 18 within the limit slide rail 15. The magnetic slide base 18 then compresses and slides the reset telescopic rod 17, driving the adjusting gear 19 and the elastic transfer guide rod 21 on both right-angle seats to move. When the adjusting gear 19 moves on the adjusting rack 20, it rotates, and through the pin, it drives the elastic transfer guide rod 21 to rotate synchronously, pressing both elastic transfer guide rods 21 on both sides into the U-shaped docking plate located at the front and lower. Within 22 (the elastic connecting rod 21 contacts and is squeezed into the U-shaped docking plate 22, undergoing elastic deformation, and then pressed into the U-shaped docking plate 22), the feedback control circuits of the temperature control seat 24 and the weather control seat 26 are simultaneously connected. The temperature simulation box 4 is used to achieve sub-zero temperature control at extremely low temperatures (this feedback circuit is an independent temperature control for refrigeration in the temperature simulation). The weather simulation mechanism simulates snowy weather, achieving synchronous adjustment of the daylighting system 3 with the weather and ambient temperature. Subsequently, when a general low-temperature environment needs to be simulated, the current flowing through the daylighting system 3 increases, causing the magnetic repulsion force generated by the electromagnetic seat 16 to increase synchronously, thereby driving the adjustment gear 19. Continuing to move, the elastic transfer rod 21 rotates out of the U-shaped docking plate 22. On the temperature control seat 24 side, the elastic transfer rod 21 will rotate into the U-shaped docking plate 22 within the three-rail system 23 (the feedback circuit in the three-rail system 23 is the non-refrigeration system in the temperature simulation). On the weather control seat 26 side, the elastic transfer rod 21 will rotate into the U-shaped docking plate 22 located in the middle, simulating rain and fog. When simulating higher and ultra-high temperatures, the current flowing through the daylighting system 3 will continuously increase, causing the elastic transfer rod 21 on the temperature control seat 24 side to dock with the U-shaped docking plate 22 and then into the three-rail system 24. The three sliding rails 23 and the adjusting rack 20 are misaligned. The elastic connecting rod 21, after being inserted into the U-shaped docking plate 22, restricts the free rotation of the adjusting gear 19. The circuit connection in the three sliding rails 23 is for the non-cooling system control of the air temperature. The elastic connecting rod 21 on one side of the weather control base 26 will be inserted into the U-shaped docking plate 22 in the double sliding rails 25 to realize the simulation of sunny days. The high temperature and ultra-high temperature environmental states corresponding to the air temperature in the double sliding rails 25 are both simulations of sunny days. It is an independent weather simulation mechanism. The double sliding rails 25 and the adjusting rack 20 are also misaligned. The advantages mentioned above are as follows: In this way, when simulating different working conditions during the photoaging test of photovoltaic panel 6, the change in input current when the irradiance of the daylight lighting system 3 changes is converted into the change in magnetic force of electromagnetic base 16. The change in magnetic force causes the change in the pushing position of magnetic slide 18, thereby realizing the independent feedback and control of ambient temperature and weather conditions. This avoids confusion and easy failure caused by the linkage of multiple control systems. The conventional mechanical structure change linkage makes the coordination and linkage of various working conditions more reliable. Only the change in input current of daylight lighting system 3 needs to be controlled to meet the dynamic changes of various working conditions during long-term photoaging test. In this invention, to simulate the daily use of the photovoltaic panel 6, the photoaging test is typically conducted using a simulated day-night cycle. A heat flow simulation chamber 5 is used to generate a warm airflow around the photovoltaic panel 6, followed by low-temperature environmental control. Because the simulated day-night temperature changes can cause some warping of the photovoltaic panel 6, affecting its photoaging resistance, two vertical clamps 12 are placed on the upper and lower surfaces of the photovoltaic panel 6, respectively, and the vertical support 11 is brought into contact with the photovoltaic panel 6, ensuring that the vertical support 11 and the edge of the photovoltaic panel 6 remain on the same plane at all times. This also ensures that the magnifying reflective plate 13 is on the same plane as the edge of the photovoltaic panel 6. Therefore, when the test... When the photovoltaic panel 6 warps at both edges during the photoaging test, the amplified reflective plate 13 will deflect upward at a certain angle. Since the amplified reflective plate 13 extends outward, the slight warping angle change of the photovoltaic panel 6 will be amplified. As a result, the light projected by the laser sensor 9 onto the amplified reflective plate 13 will change due to the deflection, causing the reflection angle of the light to change. This will allow the sensing receiving plate 10 to detect the change in the landing point of the reflected light. In this way, the slight warping of the photovoltaic panel 6 can be detected by the cooperation of the laser sensor 9 and the amplified reflective plate 13. The correlation between the warping change of the photovoltaic panel 6 and its electrical test data under different simulated working conditions can be monitored at all times, making the overall photoaging test data more comprehensive. When conducting various light aging simulation tests on the photovoltaic panel 6, the daylighting system 3 applies currents of different intensities, so that the radiation illuminance projected by the daylighting system 3 is different, which is convenient to provide a realistic light state under different weather conditions. The electromagnetic base 16 and the daylighting system 3 maintain the same current input circuit, while the simulation of various weather conditions and the ambient temperature under various weather conditions are their own independent control systems. When simulating ultra-low temperature environments, a small current is input to the daylighting system 3. This also applies a small current to the corresponding electromagnetic base 16, causing it to generate a small magnetism. This magnetism, in turn, generates a small magnetic repulsion force on the magnetic slide base 18 within the limit slide rail 15. The magnetic slide base 18 then compresses and slides the reset telescopic rod 17, driving the adjusting gear 19 and elastic transfer guide rod 21 on both right-angled seats to move. The adjusting gear 19 rotates as it moves on the adjusting rack 20, and through a pin, drives the elastic transfer guide rod 21 to rotate synchronously. This causes both elastic transfer guide rods 21 on both sides to rotate and press into the U-shaped docking plate 22 located at the lower front. Simultaneously, this connects the feedback control circuits of the temperature control base 24 and the weather control base 26, utilizing the temperature model... The simulated box 4 achieves sub-zero temperature control at extremely low temperatures (this feedback circuit is an independent temperature control for refrigeration in the temperature simulation). It uses a weather simulation mechanism to simulate snowy weather, achieving synchronous adjustment of the daylighting system 3 with the weather and ambient temperature. Subsequently, when simulating a general low-temperature environment, the current flowing through the daylighting system 3 increases, causing the magnetic repulsion force generated by the electromagnetic base 16 to increase synchronously. This drives the adjusting gear 19 to continue moving, causing the elastic transfer guide rod 21 to rotate out of the U-shaped docking plate 22. On the temperature control base 24 side, the elastic transfer guide rod 21 rotates into the U-shaped docking plate 22 within the three-rail system 23 (the feedback circuit in the three-rail system 23 is the non-refrigeration system in the temperature simulation). Meanwhile, on the weather control base 26 side, the elastic transfer guide rod 21... 1. It will rotate into the U-shaped docking plate 22 located in the middle position to simulate rain and fog weather. When simulating higher and ultra-high temperatures, the current supplied to the daylighting system 3 will continuously increase, causing the elastic connecting rod 21 on one side of the temperature control seat 24 to slide within the three-rail 23 after docking with the U-shaped docking plate 22. The simulated temperature is adjusted in real time according to the sliding position (the three-rail 23 and the adjusting rack 20 are misaligned; after the elastic connecting rod 21 is engaged with the U-shaped docking plate 22, it restricts the free rotation of the adjusting gear 19. The circuit connection within the three-rail 23 is for the non-cooling system control of the temperature). Meanwhile, the elastic connecting rod 21 on one side of the weather control seat 26 will engage with the U-shaped docking plate 22 within the double-rail 25 to achieve... The simulation of sunny weather (the double-rail 25 corresponds to high and ultra-high temperature environments, both simulating sunny weather, and is an independent weather simulation mechanism; the double-rail 25 and the adjusting rack 20 are also designed with a staggered alignment) allows for independent feedback and control of ambient temperature and weather conditions during the photovoltaic panel 6 photo-aging test, by converting the input current change of the solar lighting system 3's irradiance into a change in the magnetic force of the electromagnetic base 16, and then using this change in magnetic force to adjust the pushing position of the magnetic slide 18. This avoids confusion and malfunctions caused by the linkage of multiple control systems. The conventional mechanical structure changes and linkages make the coordination and linkage of various operating conditions more reliable, requiring only the control of the input current change of the solar lighting system 3.This can meet the dynamic changes of various operating conditions during long-term photoaging tests.
