Welcome back to PV Tech’s live coverage of SNEC PV Power Expo 2021, on this third and final day of the exhibition.
This story will be updated throughout the day, so be sure to check in regularly as PV Tech provides you live coverage from the second day of the show.
23:30 CST / 16:30 BST / 11:30 ET – That’s a wrap!
After three days of excellent, insightful and thought provoking content, SNEC 2021 has closed its doors! As you can see from all three of our daily live blogs, the solar industry has excelled itself once again with a demonstration of the scale the industry has grown to and the technological expertise it has.
Below is a list of each video interview we have conducted this week, including links to the videos on both YouTube and YouKu for our readers in mainland China (some YouKu links to follow). We’ll be taking stock of everything we’ve learned from the show floor this week for analysis to be published next week, and we also have some bonus video interviews to share.
Thank you for reading, and we hope you’ve found our coverage of SNEC 2021 enjoyable.
23:00 CST / 16:00 BST / 11:00 ET – Insuring against price spikes
Soaring material costs are plaguing the solar industry, sending production costs soaring and significantly denting product margins. Leo Xiang, general manager of Jiang Tai Insurance Brokers’ energy department, spoke to PV Tech about how module manufacturers can offset the risk of price increases.
22:30 CST / 15:30 BST / 10:30 ET – LONGi aims big
Having wrestled the lead from JinkoSolar to become the world’s largest module manufacturer by shipments, LONGi is now aiming even bigger. The company has well documented expansion plans and the vertically-integrated maker of cells and modules is targeting growth on multiple fronts. Dennis She, senior vice president at LONGi Solar, gave PV Tech the inside track on the firm’s strategy moving forward.
LONGi used the exhibition to launch its first n-type module, the Hi-MO N, which comes hot on the tails of the company continuing to push the boundaries of cell efficiency. The Hi-MO N took centre stage at LONGi’s booth, as you can see below.
22:00 CST / 15:00 BST / 10:00 ET – N-type the way forward
One of the big themes at SNEC 2021 has been the emergence of n-type products for the mass market, and Jolywood has long been a champion of the technology. We visited Jolywood’s booth and spoke to Zhifeng Liu, the company’s vice president, who explained why now n-type is no longer just the technology of tomorrow.
Some of Jolywood’s n-type products can be found on the company’s booth.

21:30 CST / 14:30 BST / 09:30 ET – Smart solar, smart grid?
Leading technology company Huawei has for a long time leveraged its expertise in other sectors such as telecoms to boost its solar product, and at SNEC this year the company is demonstrating some of its work on developing products for the zero carbon cities of tomorrow.
We spoke exclusively to Guoguang Chen, president of Huawei Smart PV and COO of Huawei Digital Power, about the company’s vision for the power sector of the future.
21:00 CST / 14:00 BST / 09:00 ET – Can the industry be united by R&D?
Research and development is one thing most solar manufacturers have in common, and Trina Solar is very much of the opinion that the industry can unite behind advancements which can benefit all. Franck Zhang, head of global product strategy and marketing at Trina Solar, spoke to PV Tech on the show floor earlier to detail how Trina believes some of the advancements Trina pursued for its Vertex line of modules could benefit the entire industry.
Trina exhibited its Vertex series, including the latest 670W variant.
20:00 CST / 13:00 BST / 08:00 ET – It’s all about the cell
There has been considerable debate in the industry about cell-level technologies in the past year, not least the discussion about which size is best, 182mm or 210mm. One thing’s for sure, demand for solar cells is set to continue soaring, placing huge emphasis on the industry’s cell providers to cater for the industry’s needs. One such company intent on doing so is Aiko Solar, who spoke to PV Tech about the company’s huge expansion plans.
L-R: Vincent Lau, overseas senior sales director at Aiko Solar, speaks to PV Tech about the company’s ambitious expansion plans, while the company’s booth attracts attention on the show floor.
19:30 CST / 12:30 BST / 07:30 ET – Trackers under the spotlight
Increases in the price of polysilicon have stolen headlines, however steel costs have also soared which has led to some concern among mounting firms, and in particular trackers which use more of the metal. Nevertheless, they remain a core element of the solar deployment industry. We spoke to Arctech about the launch of its new 2P tracker system at SNEC 2021.

17:30 CST / 10:30 BST / 05:30 ET – How are backsheets evolving?
Given the nature of the exhibition and how dominant solar modules are amongst the stands, it can perhaps be easy to forget how much technology and R&D goes into components you don’t always see, such as backsheets. Here, Mark Wu, chairman of Cybrid Technologies, discusses the company’s leading position in backsheets and its launch of encapsulants to become a one-stop-shop for PV materials.
