Tongwei’s new manufacturing facility options important enhancements in manufacturing effectivity and high quality management because the producer promotes new technological developments in its heterojunction (HJT) product traces.
Against the backdrop of intensifying competitors within the world PV trade, Tongwei Solar Technology Yancheng Base showcases the corporate’s technological innovation and eco-friendly manufacturing advances. Construction, from ground-breaking to completion of the primary module, took simply 145 days.
Yancheng Base adopts a 5G+ digital administration mannequin to hurry up the entire course of. Intelligent configuration and computerized optical inspection vastly enhance manufacturing effectivity and enhance high quality management. The deployment of automated guided automobile (AGV) carts and an clever materials distribution system guarantee correct supply of fabric to focused workshops. In addition, the usage of stereoscopic warehouses achieves an efficient connection between manufacturing and stock, additional decreasing labor and enhancing turnover effectivity.
Green manufacturing observe
Tongwei Solar integrates inexperienced ideas all through the product manufacturing course of, repeatedly upgrading its clever manufacturing to enhance manufacturing effectivity and scale back vitality consumption. The firm tracks its provide chain and carbon footprints, and has obtained a minimum of 33 home and international carbon footprint certificates.
Material suppliers endure audits by the buying, high quality, and technical departments. Raw supplies should undergo an inside new materials import course of and go validation checks earlier than being included within the invoice of supplies. A producing execution system can be utilized for configuring, querying, and documenting knowledge about manufacturing supplies. Various hyperlinks similar to silicon materials mixing ratios, silicon wafers, cells, and modules should strictly observe the carbon footprint certification necessities. In addition, the recycling of Tongwei Solar is carried out in accordance with the final technical necessities for the recycling of PV modules.
Product innovation and upgrading
In the sphere of technological innovation, Tongwei Solar has always elevated its R&D investments and achieved breakthroughs in HJT know-how. The firm’s THC-G12 module reached a peak output energy of 762.79 W and a conversion effectivity of 24.56%, based on the take a look at of the third-party evaluation physique TÜV SÜD.
Simultaneously, within the realm of tunnel oxide passivated contact (TOPCon) know-how, the TNC-G12R 66 massive rectangular module achieves an influence output of 625 W after design optimization. This represents an influence improve of greater than 40 W and an effectivity improve of as much as 0.5% in comparison with the TNC-M10 72 module. This improvement has successfully lowered the steadiness of the system value and the extent value of electrical energy (LCOE), displaying excellent efficiency. By sustaining a module width of 1,134 mm and growing the peak of two,382 mm, the packing effectivity is improved, leading to a discount in transportation prices.
The TNC-G12 module makes use of Tongwei Solar’s self-produced massive sq. cells, which allows an influence output of 720 W. This marks an influence improve of 130 W and an effectivity enchancment of 0.38% over the TNC-M10 72 module. Based on system yield analyzes carried out throughout 10 consultant world venture websites, TNC-G12 modules present a mean LCOE discount of two.64% in comparison with modules of the bifacial TNC-M10 72, with the very best discount reaching 4.30%. In utility-scale energy vegetation, TNC-G12 modules present important benefits in use.
