Trick Solar Manufacturers Back 182mm Module Size for 2021

Nov 17, 2020 11:10 PM ET
  • 3 of the most significant module manufacturers around the world, Jinko, JA and Longi are wagering that with their mixed 54GW in capability, the 182 mm module will certainly face little headwinds to market acceptance in 2021.

The significance of criteria, and also standardisation in the solar industry can never ever be overemphasised, thinking about the numerous components that have to interact to make an effective solar plant. As a market that sees every component as well as part travel through multiple examinations as well as components for safety and security as well as efficiency, and also major change is done after terrific factor to consider, and extra significantly, purchase in from appropriate partners in the eco system. For the leading module manufacturers in business, one such inquiry has been the size of modules going forward.

While the industry has broad agreement on the possibility of, and also require for larger module dimensions, the ideal dimension that would work for every person is still being debated. In just the past three years, module dimensions have moved frenetically after greater than a years of steady size of 156 mm. Now, we have modules varying from 157mm to 210mm and a lot more in between, vying for interest.

Which is where, the consensus on the 182mm size issues More so, due to its backing by essential module suppliers, as well as various other sector partners in inverters, testing and even more.

At a conference in Shanghai recently, solar inverter and tracker makes, power layout institutes, EPC enterprises and also third-party accreditation institutions released a comprehensive statement on the layout, manufacturing price, sustaining framework, system application as well as product certification of the 182mm modules.

Li Shaotang, Senior Product Manager of Longi Solar, commented, "As early as 2018, the market came out with the concept of having bigger module size to enhance the power. Nevertheless, bigger size does not suggest far better efficiency. Numerous limit problems for detailed consideration consist of manufacturing, transport, reliability as well as manual installment. The 182mm modules efficiently sustain the existing commercial requirements and electrical system. Furthermore, in terms of LCOE, 182mm modules are superior to 210mm due to lower system price, far better generation capacity as well as reliability. The previous is ideal for massive ground-mount power plants with flat terrain".

" The boost in module dimension needs consideration of a number of factors, ranging from module's circuit layout, element matching style, reliability to procedure ability, packaging and also transportation, system style, and also post-operation and also maintenance." claimed Zou Chicheng, Vice President of TUV Rhein. Zou recommended that business seek an optimum remedy between size as well as safety and security from the viewpoint of accreditation.

Meanwhile, the market is steadily involving terms with the fact that bigger module dimensions aid in saving prices. Yu Hanbo, Senior Manager of Global Products at JinkoSolar, claimed, "Improving power generation by reducing line loss and inner loss is one of the ways to minimize prices."

With three of the most significant manufacturers behind them, the 182 mm modules have gradually become part of the automation stage.182 mm items have a variety of certified distributors in each of the processes, consisting of crystal-pulling, slicing, cell as well as module production. It is estimated that in 2021, the production capacity of pull crystal-pulling, glass and film for the 182mm items will be more than 50% of the industry's full capacity, as well as the proportion of pulling crystals will be as high as 91.7%.

Huawei as well as Sungrow, two essential inverter manufacturers, indicated that associated items can sustain 182mm modules comprehensively. According to Gan Binbin, Global Solutions Director at Huawei, the high-power modules generate the obstacle of matching the optimum current of the inverter MPPT with the functioning current of the modules. In addition, the reliability dangers of split, hot spot and diode additionally enhance. Nevertheless, he added that Huawei's items can completely support all modules and also utilize AI BOOST's intelligent formulas and diagnostics to properly minimize expense and boost effectiveness.

Zhang Yanhu, Vice President of Sungrow, claimed, "The increase in module current will certainly raise the diameter of low-voltage DC cable televisions, therefore driving up the material cost. At the same time, too much variation of modules existing will likewise influence the performance of string inverters as well as combiner boxes. While centralized inverters can be flexibly adapted to different versions of modules, the DC combiner boxes can be adapted to 182mm and also 210mm modules."

For PV trackers, Guo Zhikai, Senior Product Director of tracker leader NEXTracker, stated, "Tracking system has actually met one difficulty after an additional as solar modules upgrade. For today's 182mm module, 1P/NX Horizon as well as 2P/NX Gemini items are completely suitable with its 72-cell version. The 78 version modules can additionally reduce expenses, as well as solar module lots values have actually been verified, which covers 100% of the project needs. In terms of integrity, it has actually passed the new wind tunnel examination, and even the biggest module dimension can ensure its security on the tracker."

What we can be sure of is that with standardisation of the 182mm size, modules with ranked output of 500 watts and even more will certainly end up being actually usual next year, with big effects for LCOE of solar tasks, as these modules could cut down need of land as well, to an extent. The difficulty as always? Keep lowering those prices, so that the remainder of the market can keep up.
