Figure 1 As shown, Figure 1 The structure diagram of the portable test device 10 for the full irradiation section power of photovoltaic modules provided in the embodiment of the present application is as follows. The portable test device 10 for the full irradiation section power of photovoltaic modules of the present application can be used for the portable test purpose of the full irradiation section power of photovoltaic modules.
[0036] In order to more clearly illustrate the structure of the portable test device 10 for the full irradiation section power of a photovoltaic module, the portable test device 10 for the full irradiation section power of a photovoltaic module will be introduced below in conjunction with the accompanying drawings. Figure 1 As shown, Figure 1 A schematic diagram of the structure of a portable photovoltaic module full-irradiation power test device 10 provided in an embodiment of the present application.
[0037] A portable test device 10 for the full irradiation section power of a photovoltaic module comprises a support azimuth adjustment module 100, an inclination adjustment module 200, a shading component 300, an irradiation tester 400 and a power tester 500. The support azimuth adjustment module 100 can move in position. The inclination adjustment module 200 comprises a support plate 201 relatively arranged on the support azimuth adjustment module 100 and at least two support rods 202 mounted on the support plate 201. The support plate 201 is provided with a plurality of adjustment holes. The support rod 202 is used to support the photovoltaic module to be tested. The support rod 202 can be embedded in the adjustment holes at different positions to adjust the angle of the photovoltaic module on the support rod 202. The shading component 300 comprises a shading film 301 and a driving component. The shading film 301 is arranged above the support azimuth adjustment module 100, and the shading film 301 comprises a plurality of test areas 3011, and the light transmittance of different test areas 3011 is different. The driving component is connected to the shading film 301 to drive the shading film 301 to move. The irradiation tester 400 and the power tester 500 are installed on the support azimuth adjustment module 100. The specific value of the irradiation is verified by the irradiation tester 400, and the irradiation intensity and output power are extended to other values by using the linear relationship between the output power and the irradiation intensity of the photovoltaic module.
[0038] In some of these embodiments, radiation tester 400 may be a radiation meter.
[0039] In some embodiments, the power tester 500 may be an IV tester. The light shielding film 301 passes through the photovoltaic module at a certain speed, and the power tester 500 may read the power data according to the time it takes for the light shielding film 301 to pass through the photovoltaic module.
[0040] In some embodiments, the support orientation adjustment module 100 includes a plurality of mounting plates 101. The plurality of mounting plates 101 are interconnected to form a rectangular parallelepiped structure.
[0041] In some embodiments, adjacent mounting plates 101 are connected by hinges. The arrangement of connecting adjacent mounting plates 101 by hinges facilitates the disassembly and installation of the support orientation adjustment module 100.
[0042] In some embodiments, a roller 102 is connected to the bottommost mounting plate 101. The roller 102 is used to assist in supporting the position adjustment module 100 to move.
[0043] Preferably, the roller 102 is a universal wheel. Further, the roller 102 has a self-locking function.
[0044] In some of the embodiments, a plurality of adjustment holes are distributed in a matrix on the support plate 201 .
[0045] In some of the embodiments, multiple adjustment holes are evenly distributed on the support plate 201. Such a configuration can ensure that the adjustable range of the support rod 202 meets the requirements and maximize the adjustable angle of the photovoltaic component, simulating the installation angle of the photovoltaic component within the maximum range.
[0046] In some embodiments, the light transmittance of the light shielding film 301 is between 10% and 90%. The light transmittance of the light shielding film 301 can be set according to actual needs. For example, the light transmittance of different areas on the same light shielding film 301 can be different.
[0047] In some of these examples, see Figure 2 As shown, the shading film 301 is provided with a plurality of test areas 3011 with light transmittance changing in a gradient sequence in sequence along its moving direction, and the gradient of light transmittance change of adjacent test areas 3011 is 10%-20%.
[0048] In some of the embodiments, along the moving direction of the light shielding film 301 , the front end and the rear end of the test area 3011 are respectively provided with a preparation area 3012 , and the light transmittance of the preparation area 3012 is 100%.
[0049] In some of these examples, see Figure 3 As shown, the light-shielding film 301 is a thin film with various light transmittances obtained by dyeing with inks of different concentrations.
[0050] In some of these examples, see Figure 4 As shown, the light-shielding film 301 is a thin film with different light transmittances obtained by covering different areas with ink.
[0051] In some embodiments, the light-shielding film 301 is a thin film with different light transmittances obtained by overlapping multiple film layers with different light transmittances.
[0052] In some embodiments, the shading component 300 further includes at least two rotating shafts 302. The rotating shafts 302 are rotatably connected to the upper position of the tilt adjustment module 200, the shading film 301 is sleeved and connected to the rotating shafts 302, and the driving component is connected to the rotating shafts 302. The shading film 301 is located above the photovoltaic module to simulate full irradiation.
[0053] In some of these embodiments, see Figure 2 As shown, a group of shading films 301 includes 3 test areas 3011 and 2 preparatory areas 3012. The preparatory areas 3012 are designed to prevent the redundancy of the shading film 301 from being unbalanced in the matching of the movement speed. The length of the two preparatory areas 3012 can be set as needed, for example, the length of the preparatory area 3012 is 5 meters. The gradient of the light transmittance change of adjacent test areas 3011 in a test cycle is designed to be 10%, and the length of each test area 3011 is 2.5 meters. The IV tester is set to test one power point in 2 seconds. 12 power points are set on a group of shading films 301, which takes 24 seconds. There are 10 groups of test areas 3011 with different light transmittances, and it takes 240 seconds to complete the entire test cycle. The linear speed of the driving component to drive the shading film 301 is 42 cm per second, the shading cover is expected to have a diameter of 5 cm, the driving component rotates at about 2.8 revolutions per second, and the driving component can use a low-speed motor.
[0054] It should be noted that after the installation of the portable test device 10 for the full irradiation section power of the photovoltaic module is completed, the overall position can be adjusted so that the device faces the sunlight directly, and the tilt adjustment module 200 is adjusted at the same time to prevent the photovoltaic module IAM factor from causing test errors. The irradiation tester 400 is set on one side of the photovoltaic module to record the accurate irradiation received by the photovoltaic module to prevent the error of the shading film 301. For the weak light part, a longer and more sophisticated shading film 301 can be designed to maintain the reliability of the data. The azimuth angle of the sun relative to the fixed point on the ground of the earth changes by 15° in 1 hour, and the azimuth angle of solar energy changes by only 1° in 240 seconds. According to the IAM characteristics of photovoltaic modules, most photovoltaic modules have no loss within 5° of the incident tilt angle, so the test data of this application is reliable.
[0055] When the above-mentioned photovoltaic module full-irradiation section power portable test device 10 is used, it includes the following steps:
[0056] S1. On a relatively flat outdoor surface, install a portable test device 10 for the full-irradiation power of a combined photovoltaic module.
[0057] S2. Raise the support plates 201 on both sides, set a number of support rods 202 on the opposite support plates 201, and determine the inclination angle of the plane formed by the multiple support rods 202 to achieve the best perpendicularity of the plane where the multiple support rods 202 are located to the sunlight, thereby ensuring that the light-receiving surface of the photovoltaic module is perpendicular to the sunlight.
[0058] S3. Place the photovoltaic modules to be tested on a plurality of support rods 202, install the side radiation tester 400, connect the power tester 500, and supply power through the device system.
[0059] S4. Adjust the roller 102 at the bottom to make the portable photovoltaic module full-irradiation section power test device 10 face the sun.
[0060] S5. Start the device system and start the power tester 500 to obtain data and draw a graph to obtain the operating power of the photovoltaic module at each irradiation. Draw a graph of the 120 power variation data measured for 240 seconds with irradiation. Since the irradiance and the photovoltaic module power have a very strong linear relationship and will not change suddenly, at this time, extend other unmeasured data points on the graph to obtain the power value of all irradiation sections, and the power value has a high reliability.
[0061] In summary, the portable power test device 10 for the full irradiation section of a photovoltaic module of the present invention is easy to assemble and use, can be moved to any project workshop that needs to be tested for testing, and the data has reliable accuracy, which is highly feasible for the performance evaluation of photovoltaic modules. The portable power test device 10 for the full irradiation section of a photovoltaic module of the present invention is highly convenient and low in cost, and can allow users to quickly and effectively measure the power of photovoltaic modules in the full irradiation section. It can not only protect the rights and interests of consumers at the application end, and facilitate the finding of the extreme value of batch photovoltaic modules, but also can realize the rapid comparison of the power attenuation of different photovoltaic modules in photovoltaic demonstration projects.
[0062] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
[0063] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0064] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
