The bifacial modules based on M6 are represented with a good cell technology mix. In addition to PERC, modules based on TOPCon, the first HJT variants and a few multicrystalline products are offered based on this wafer size. M6 is nothing but a 166 mm pseudo-square format, which was believed to become a standard when it was introduced in 2018. Thus several companies have successfully adapted wafer size and commercialized module products. TaiyangNews Bifacial Solar 2021 – Part 1: Cells and Modules report has collected the data of 22 module products from selected companies that are commercially offering module products based on M6 format.
However, JA Solar is offering two modules based on a somewhat atypical size of 168 mm, which are also listed here. Within the n-type category, while Jolywood is offering TOPCon modules, Jinergy is relying on HJT cells. Both the companies are offering modules in 72 and 60-cell layout. For the larger configuration, Jolywood’s TOPCon product has a labelled wattage of 470 W, while Jinergy’s HJT M6 panel is rated with 465 W. However, CSI is offering the product with the largest number of cells – 78, thus its BiHiKu5, a mono-PERC module comes with the highest power rating of 490 W. The multicrystalline variant of this model has next highest power of 475 W. The 72-cell classification M6 PERC modules contains 12 products, of which one is a multi-module. The power rating of the 11 monocrystalline products falls between 465 W and 450 W. Among the 60-cell products, one is a 380 W module and three reach 375 W. The entire listing of bifacial products are based on MBB and half-cell module technology, while two of Jinergy’s products employ transparent backsheet as rear cover. When it comes to bifaciality, Jinergy’s HJT modules is rated with the highest bifaciality of above 85%, followed by Jolywood’s TOPCon modules at 80%. All the PERC modules featured here have an average bifaciality of 70%.
