Walking into the Wusha solar modules factory of LESSO Group, we can see a row of intelligent production and testing equipment with a full sense of science and technology, which is the testing assembly line system of several solar modules. Recently, the laboratory of solar module of LESSO has been put into use, and in the future, it will take the solar module as the entry point, continuously increase the research and development of new energy industry, and continue to help LESSO's innovative development of new energy industry with high-efficiency components.
For the manufacturing industry, improving quality and increasing production is the most important thing of enterprises, and product quality has also become a sea pin for stable business growth. Take the module production process as an example, from a piece of crystalline silicon solar cell to a complete high-efficiency solar module, you need to go through the scribing, welding, laminating, laminating, appearance of the EL1 test, IV test, finished product inspection and other complex processes, quality testing through the cell to the final module finished product always.
In the intelligent production process, solar modules go through several rounds of testing and inspection, such as IV testing, EL testing, appearance inspection, etc. However, this is not enough, and the laboratory is needed to complete the basic material level and weathering reliability testing.
In the laboratory, according to IEC61215, IEC61730 and other standards, more than twenty sets of solar module test equipment can carry out standard procedures or double or triple rigor tests. For example, the highly accelerated life test chamber is a process that utilizes a shock system of rapid high and low temperature changes to reveal design flaws and deficiencies in electronic and mechanical assemblies; the wet leakage test system evaluates the insulating properties of components under wet conditions and confirms whether moisture from rain, fog, dew or melting snow can enter the internal circuitry portion of the component, leading to possible corrosion, grounding faults, or safety hazards.
Equipped with the most advanced solar testing equipment and technology, the Laboratory of solar Modules of LESSO carries out comprehensive and accurate testing and analysis on the efficiency, stability and safety of solar modules through innovative scientific and technological means, in order to ensure the high quality and high efficiency of products.
With the accelerated pace of global energy transformation, realizing intelligent manufacturing through technology research and development, and promoting industrial upgrading and breakthrough has become a necessary path for the rise of the solar industry. The operation of LESSO solar module laboratory will provide all-round technical support for the high-efficiency solar module industry, which is an important support for product R&D and technological innovation.
A solar module is placed inside the instrument, and it only takes a few seconds to immediately present the maximum power and electrical performance of the solar module, etc., which is the IV module tester of the solar module laboratory. In addition to this, dynamic load mechanical testing machine, universal material testing machine, hail testing machine and other solar module testing machine, through the detection of the experimental process may produce a short circuit and circuit breakage, appearance defects, electrical performance attenuation rate, insulation resistance, hail impact in order to determine the component to withstand the wind, snow and other load capacity.
These test equipments provide high-efficiency solar modules with the ability to characterize and test, which improves the accuracy and validity of the measurement results, and provides a reliable basis for the subsequent product research and development. LESSO will gradually carry out high-efficiency solar product inspection, testing, certification and other technical services and other related businesses, accurately grasp the direction of the industry’s key common technologies, organically combine technological research and development with industrial incubation, and provide cutting-edge scientific and technological support for the solar industry.
In the future, LESSO solar module laboratory will rely on CNAS and other system requirements to complete the updating and upgrading of the laboratory, so as to let intelligent innovation drive the industry’s professional, sustained and healthy development, and to ensure that it will be invincible in the torrent of the rapid iteration and renewal of the new energy industry.
