pv journal: Final yr, Trina Photo voltaic launched the primary n-type TOPCon photo voltaic modules based mostly on 210 mm cells. What makes this product totally different from different TOPCon panels?
Zhang Yingbin: 210 + N sequence merchandise have excellent traits, together with low temperature coefficient, low photovoltaic attenuation, excessive bifacial price, low first-year attenuation, and linear attenuation, and in addition adhere to the 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 greater than n-type market opponents.
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 robust 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 might 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% greater. On the identical time, the low voltage design can improve the wire energy with the identical wire voltage.
When it comes to energy technology, based on our greater than half a yr verification examine by TUV and CPVT in areas of various latitudes, the experimental information proves that the 600 W-plus product based mostly on 210 mm wafer can improve the facility technology acquire by about 1.6% to 2.1%, primarily from the higher low-irradiation efficiency of the 600 W-plus product. The most recent gross sales information additionally reveals the rising recognition of 210mm merchandise. Within the third quarter of 2022, almost 76 GW of 210 mm modules have been shipped worldwide, with Trina Photo voltaic delivery a cumulative whole of 40 GW.
The 210+N sequence contains quite a lot of merchandise. For what purposes are these panels supposed?
Presently, Trina’s foremost 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 the benefits of the Vertex household, with excessive energy, excessive effectivity, excessive energy technology and excessive reliability, and many others. to 30 W, and the module effectivity reaches 22.4%. Based mostly on 210mm rectangular silicon wafer (210R) cell know-how, with excessive form design and low voltage benefit, the n-type 605 W module absolutely 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, it’s doable to string 6-12 extra modules per string, with out losing any size. on. That is the “finest companion” within the monitoring bracket. It will assist cut back the price of BOS.
The Vertex N 695 W module has a really excessive energy, 70 W greater than most n-type opponents available on the market. The effectivity can also be elevated to 22.4%, and is completely appropriate for varied utility-scale energy vegetation. Extremely-low attenuation for the whole life cycle of energy technology escort, optimized bifacial energy technology efficiency to carry greater bifacial revenue, ultra-low working temperature coefficient makes energy technology safer, mixed with modern low voltage, excessive energy design to attain greater string energy, cut back the price of electrical energy to a brand new low stage.
Vertex S+ is for rooftops and a few C&I situations, specifically designed for European and Asian households based mostly on EU and Asian rules. With a measurement 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 sequence?
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 High-Runner Program. In 2022, our whole 8 GW n-type capability may have a mass manufacturing effectivity of round 25%, it’s anticipated that the effectivity will improve to 25.5% in 2023 and 26% in 2024 with a mean annual improve of 0.4 -0.5%
Does Trina Photo voltaic plan to construct capacities for this module sequence?
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 may 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 also 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 availability of n-type manufacturing capability and optimize the general structure of the upstream and downstream of the n-type industrial chain.
I believe the manufacturing capability may be simply elevated together with the simple acceptance of 210 + N out there. Moreover, vertical integration will remove p-type deficiencies throughout surprising bottlenecks.
How will Trina Photo voltaic’s transition to n-Kind know-how have an effect on the business and the market?
The idea of 600W+ has turn out to be a worldwide consensus. By the tip of 2022, there might be a complete of 90 GW of module capability achieved for 210 mm based mostly merchandise, and penetration has grown to 10% and is now heading in direction of a 30% market share. We imagine that 210 and 600W+ work collectively in a brand new ecosystem within the industrial worth chain.
The 210+N idea is in a means an extension of the 600W+, which can turn out to be a pattern all through the photo voltaic PV business. As you recognize, not solely TOPCon, but in addition HJT and IBC may be based mostly on the 210mm product know-how platform.
What’s your view on the long run growth of know-how? Will TOPCon compete with heterojunction?
I believe 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 many others., and may vastly cut back the funding of commercial duplication.
These within the line of 4 highs and one low (greater energy, greater effectivity, greater energy technology, greater reliability, and decrease LCOE) might be mainstream.
