SNEC: Risen Energy Launches 210 mm, 700W Module

SNEC 2021 at Shanghai continues to throw up key launches, thanks to a roaring domestic market. The latest news comes from Risen Energy of China that has launched a new N-type module with up to 700W output in a single wafer which it claims combines the advantages of and complements both TOPCon and heterojunction (HJT) cell technologies.

The dual technology is integrated into the product, bringing more stable performance and higher power generation, stated Risen Energy.

Earlier, Risen had launched its Titan series of modules in August last year with 600W output, based on G12 / 210mm sized silicon wafers with the highest capacity of 660W based on PERC technology. By the end of 2022, it plans to switch over from PERC to HJT technology. In March this year, the company secured TUV South Germany’s certification for its HJT module output reaching over 600W.

Risen Energy calls its [email protected] panel based on 66 of 210mm size cells as the industry’s ‘1^st mass-produced’ module with a power rating of up to 700W and an overall efficiency of 22.5%. With this, Risen claims the industry has started off on the 7.0 era. Earlier, Risen has also been one of the earliest to announce a 600 W module, and last year, even an 800 W module, in test conditions.

It added, “[email protected] therefore has the advantages of N-type cells such as ultra-low temperature coefficient, excellent low-light performance, and bifaciality greater than 80%, and N-type silicon wafers do not have the LID (light induced degradation) phenomenon caused by the formation of B-O complex.”

For this very high-power module product, Risen Energy said it has used advanced technologies as non-destructive slicing of cells for half cell layout, multi-busbar (MBB) and high-density packaging. These while improving efficiency, effectively reduces risk of cell cracking and hotspots.

The technical team of Risen Energy explained that compared with traditional 182mm sized modules with 540W output, [email protected]’s floor space has been reduced by 6.60%, while installed capacity has been increased by 29.63%, overall BOS cost reduction is down by about 6.68% to 8.95%, and the LCOE is lowered by about 4.84% to 6.16%. Calling 540W modules as traditional might rankle with developers in India and many other markets, who have barely started considering modules in 500W and above output range.

On sticking with 210mm silicon wafer size for its [email protected] module, Risen Energy says that these wafer sizes create the highest revenue for customers and will soon become  mainstream.

Risen Energy has also announced plans to scale up its capacity to 30 GW by the end of 2021.
