Chinese LONGi Issues White Paper on its Smart Soldering Technology

• China-based leading solar PV manufacturer LONGi has launched a white paper on its proprietary "Smart Soldering" technology, used in its new-generation Hi-MO 5 series high-power 182mm modules.

With the recurring quantity application of large-format PV modules in utility-scale plants, the special technology can ensure their packing capability, making it possible for power yield to be maximized throughout their whole lifecycle, supplying even more value-added benefits to international investors in nuclear power plant, partners as well as clients.

It is typically approved that the introduction of high-efficiency modules can improve PV installed ability in a restricted space, decreasing both the financial investment required in system materials and also equipment as well as the use of sources such as glass or EVA, which highlights why optimising conversion performance continues to be a long-lasting go for PV technology advancement.

LONGi revealed its proprietary Smart Soldering technology in June 2020, with the launch of the 182mm Hi-MO 5, a product developed for the grid parity age, combining effectiveness, power, reduced BOS expense and dependability. By using fractional bow, it is possible to make the most of use of sunlight on the front side of a module through the triangular section, attaining an extra trusted cell interconnection with mini gap style. Evaluating has actually shown that, with Smart Soldering technology, module efficiency can be enhanced by 0.3% in contrast with conventional MBB technology.

Throughout the module production procedure, the major technological difficulties of removing the space between interconnected cells included maintaining precision as well as staying clear of fracturing. Given that conventional bows could not reduce the issue, a "round shaping ribbon" interconnecting cells with a tiny void was created. While it was much less expensive, it still remained tough to keep the void in between cells, with mini splits at the joint still an opportunity.

The Smart Soldering technology created by the company makes use of incorporated fractional bow with a little void link. The ribbon is softened by an annealing process and interior tension is removed, allowing both greater producing return and integrity. The tiny gap link attained stays clear of micro fractures. The technology underwent a number of reliability tests to guarantee its effectiveness.

By releasing its Smart Soldering technology, LONGi's objective is to boost effectiveness as well as reliability through the entire lifecycle of a PV module, along with half-cut as well as MBB technologies. With the raising application of large-formart PV modules, the distinct nature of the Smart Soldering technology will virtually ensure their loading capability, making it possible for power outcome to be increased and also much more advantages to be supplied to customers around the world, adding to the success of carbon neutrality objectives.
