pv journal: Final 12 months, Trina Photo voltaic launched the primary n-type TOPCon photo voltaic modules primarily based on 210 mm cells. What makes this product totally different from different TOPCon panels?
Zhang Yingbin: 210 + N collection merchandise have excellent traits, together with low temperature coefficient, low photovoltaic attenuation, excessive bifacial price, low first-year attenuation, and linear attenuation, and likewise adhere to some great benefits of high-power output, excessive effectivity, excessive. energy technology, and excessive reliability of the Vertex household, whose module energy is 30 W to 70 W larger than n-type market rivals.
Enhancing effectivity and lowering prices are everlasting themes and relentless pursuits all through the PV Trade. Trina Photo voltaic leads the 600 W-plus alliance that has established a powerful industrial chain alliance with excessive energy output, excessive conversion effectivity, excessive reliability, and low energy prices. Whereas the mix of 210 mm wafer and n-type cell tech can be an amplifier for the efficiency of the module. In comparison with 182 mm wafer merchandise, 70 W extra energy may be generated for every panel piece, and the effectivity is about 0.2% larger. On the identical time, the low voltage design can enhance the wire energy with the identical wire voltage.
When it comes to energy technology, in line with our greater than half a 12 months verification research by TUV and CPVT in areas of various latitudes, the experimental information proves that the 600 W-plus product primarily based on 210 mm wafer can enhance the facility technology achieve by about 1.6% to 2.1%, primarily from the higher low-irradiation efficiency of the 600 W-plus product. The newest gross sales information additionally reveals the rising recognition of 210mm merchandise. Within the third quarter of 2022, almost 76 GW of 210 mm modules had been shipped worldwide, with Trina Photo voltaic transport a cumulative complete of 40 GW.
The 210+N collection consists of quite a lot of merchandise. For what purposes are these panels supposed?
At the moment, Trina’s fundamental n-type merchandise are the brand new technology Vertex N 605 W, Vertex N 695 W, and Vertex S+ 445 W. The Vertex N 605 W module is appropriate for utility-scale energy vegetation and a few C&I distributed PV, which follows. of some great benefits of the Vertex household, with excessive energy, excessive effectivity, excessive energy technology and excessive reliability, and so on. to 30 W, and the module effectivity reaches 22.4%. Primarily based on 210mm rectangular silicon wafer (210R) cell expertise, with excessive form design and low voltage benefit, the n-type 605 W module totally makes use of the monitoring bracket size of 104 meters. In comparison with the overall n-type 72- and 78-cell modules within the business, 6-12 extra modules may be strung per string, with out losing any size. That is the “finest associate” within the monitoring bracket. This may assist cut back the price of BOS.
The Vertex N 695 W module has a really excessive energy, 70 W larger than most n-type rivals in the marketplace. The effectivity can be elevated to 22.4%, and is completely appropriate for numerous utility-scale energy vegetation. Extremely-low attenuation for your entire life cycle of energy technology escort, optimized bifacial energy technology efficiency to convey larger bifacial revenue, ultra-low working temperature coefficient makes energy technology safer, mixed with modern low voltage, excessive energy design to attain larger string energy, cut back the price of electrical energy to a brand new low degree.
Vertex S+ is for rooftops and a few C&I situations, specifically designed for European and Asian households primarily based on EU and Asian laws. With a dimension of lower than 1.8 meters, a weight of lower than 22 kg, this 1.6 mm + 1.6 mm double glass module is accessible for people who can function alone.
Does Trina Photo voltaic have an environment friendly roadmap for the 210+N collection?
Trina Photo voltaic began the analysis of n-type photo voltaic cell since 2015. We constructed a pilot line of 500 MW in 2018 with the promotion of PV Prime-Runner Program. In 2022, our complete 8 GW n-type capability can have a mass manufacturing effectivity of round 25%, it’s anticipated that the effectivity will enhance to 25.5% in 2023 and 26% in 2024 with a mean annual enhance of 0.4 -0.5%
Does Trina Photo voltaic plan to construct capacities for this module collection?
In H2 of 2022, Trina Photo voltaic will begin mass manufacturing of latest technology 210+N module merchandise, and in Q1 of 2023, Trina Photo voltaic can have a complete of over 10 GW of n-type module capability which is anticipated to develop to 30 GW. by the tip of 2023.
Trina Photo voltaic has constructed a brand new 210+N manufacturing facility within the Integration PV Industrial Park situated in Xining, Qinghai province. The brand new manufacturing base is anticipated to have an annual capability of 300,000 tons of silicon metallic, 150,000 tons of high-purity polysilicon, 35 GW of ingot casting, 10 GW of wafers, 10 GW of photo voltaic cells, 10 GW of PV modules and 15GW to assist module auxiliary supplies. We plan to finish all development and fee all capacities by the tip of 2025. The corporate can be investing within the development of 15 GW of photo voltaic cells and 15 GW of PV modules yearly in Huai’an, Jiangsu Province. We offer a full assure of the provision of n-type manufacturing capability and optimize the general format of the upstream and downstream of the n-type industrial chain.
I feel the manufacturing capability may be simply elevated together with the simple acceptance of 210 + N out there. In addition to, vertical integration will get rid of p-type deficiencies throughout surprising bottlenecks.
How will Trina Photo voltaic’s transition to n-Sort expertise have an effect on the business and the market?
The idea of 600W+ has turn out to be a world consensus. By the tip of 2022, there can be a complete of 90 GW of module capability achieved for 210 mm primarily based merchandise, and penetration has grown to 10% and is now heading in the direction of a 30% market share. We consider that 210 and 600W+ work collectively in a brand new ecosystem within the industrial worth chain.
The 210+N idea is in a approach an extension of the 600W+, which can turn out to be a development all through the photo voltaic PV business. As you understand, not solely TOPCon, but in addition HJT and IBC may be primarily based on the 210mm product expertise platform.
What’s your view on the longer term growth of expertise? Will TOPCon compete with heterojunction?
I feel 210+X is the course. There are extra cell applied sciences than n. 210+N solves the ecological issues we confronted earlier than together with glass, junction field, body, bracket, and so on., and might tremendously cut back the funding of commercial duplication.
These within the line of 4 highs and one low (larger energy, larger effectivity, larger energy technology, larger reliability, and decrease LCOE) can be mainstream.
