Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a device for verifying the performance of photovoltaic modules. Background Art

[0002] The development direction of photovoltaic module technology is to improve efficiency and reduce internal losses. The performance of photovoltaic modules can be evaluated through laboratory STC testing, which examines their power generation performance under specific conditions (such as light intensity, temperature, and humidity). However, different types of photovoltaic modules and the climatic conditions of actual installation locations vary greatly, and STC measurements cannot fully reflect the actual performance output of photovoltaic modules. Performance test data from photovoltaic modules under real-world outdoor conditions is more convincing, making empirical research on photovoltaic module performance indispensable. Empirical research can, firstly, provide a basis for the design and optimization of photovoltaic systems, thereby improving system efficiency and performance. Secondly, it can identify and resolve problems that may arise in the actual application of photovoltaic modules, promoting the improvement and upgrading of module technology. Thirdly, through long-term empirical data accumulation and big data analysis, it can trace the root causes and identify technical bottlenecks in the supply chain (silicon material-wafer-cell-module) and coordination deficiencies in the string connection process. This can lead to comprehensive system integration and optimization, reducing costs and improving efficiency. Empirical research on photovoltaic modules is an indispensable part of the photovoltaic industry.

[0003] Currently, empirical research on photovoltaic modules is rapidly gaining momentum in the industry. Its implementation generally involves: developing a plan to validate the advancement of a specific technology and producing different types of photovoltaic modules; demarcating areas for different module types based on site selection and establishing a demonstration platform; project construction and grid connection; and data collection, comparative analysis, and summary, followed by report generation. The key to the success of empirical research lies in avoiding interference from "asymmetric" factors. This requires establishing a demonstration platform that is completely equivalent to the verification conditions, except for the verification conditions. These "asymmetric" factors include factors affecting light resources, temperature, humidity, and other direct and indirect factors. Current implementation issues in the industry specifically manifest as: 1) errors in testing and verification due to system equipment errors and inconsistent grid connection conditions. 2) Bifacial modules have become the mainstream in the industry, and verification brackets can obstruct the back of the modules, preventing full performance and resulting in errors in verification. 3) Bracket height and tilt angle are two key parameters for verification adjustments. Each adjustment requires rebuilding the demonstration platform, which is complex and costly. Utility Model Content

[0050] The internal structure of the energy storage control system box 12 is as follows: Figure 8As shown, the energy storage control system box 12 has four layers, separated by partitions. From bottom to top, the devices are: energy storage battery 3, first power controller 4, second power controller 6, and charge / discharge controller 2. The first power controller 4 has two circuits: one connected to the energy storage battery 3 via a cable, and the other connected to the electric actuator 5 via a cable that connects one end to the second power controller 6. The second power controller 6 has two circuits: one connected to the energy storage battery 3 via a cable, and the other connected to the second power controller 6 via a cable that connects one end to the second power controller 6, and the other connected to the electric actuator 5 via a cable that connects one end to the second power controller 6.

The evaluation of photovoltaic power generation performance is closely related to the environmental climate.

[0054] The third is the operating status of the system, including the data of the charge and discharge controller 2 (the status of the energy storage battery 3, the status of the IV curve tester 8, the status of the meteorological system, the status of the data acquisition communicator 9), the status data of the first power controller 4 (the operating status of the electric push rod 5, the height of the photovoltaic module 1), and the status data of the second power controller (the operating status of the electric lifting column 7, the tilt angle of the photovoltaic module 1).

[0055] The above three types of partial data are collected and integrated at the data acquisition communicator 9 and sent remotely through the communication antenna 9-1. The communication line connection between each device must pass through the wire pipe 14-2, the bracket longitudinal beam 11-2 and the bracket cross beam 11-1.

[0056] In the device for verifying the performance of photovoltaic modules provided in this embodiment, the support cross beam 11-1 and the support longitudinal beam 11-2 are fixed around the photovoltaic module 1.
