Sunport Power says it has optimized its S6 flexible module product in a way that could grow the BIPV market. After launching in 2018 and later achieving a successful production on pilot line, S6 was continuously upgraded and optimized by Sunport Power’s R&D team, hitting a module efficiency of 21.2% with the latest version of the S6 module.
The S6 Flexible module uses the company’s unique Metal Wrap Through (MWT) technology, which “is not a merely technology, but a platform on which many other cell technologies can be attached on,” said Martin Green, chief scientist of Sunport Power. Equipped with MWT, the S6 flexible module is known for being light, thin, flexible and lead-free. The size, weight and flexibility of the S6 module is especially suitable for curved surface, low-load capacity roofs, and facades, etc.
MWT technology
The MWT is an advanced back contact technology to increase solar cell and module efficiency by eliminating the busbar on the front side, and deploy both positive and negative electrodes on the rear side. Compared to conventional module, the power yield of MWT products increased by 3% and around 15 W more output.
The silicon-based flexible module is only 4 kg in weight and 1.4mm thick, compared to a conventional PV module 19 kg in weight and 35-40mm thick. This makes S6 especially suitable for application of BIPV which requires strict specifications of weight in many scenarios, such as roof, wall, sunshade, etc.
With the help of selected special polymer materials the front layer of the S6 module has outstanding bending flexibility and with minimum curve radius of 25 cm, which greatly expands the application and possibility.
With unique design, S6 flexible module successfully achieves lead-free by using conductive foil and becomes an eco-friendly product.
Product guarantee
The newly developed S6 module honored certificate by TUV. The first year degradation is less than 2% and linear power output will be guaranteed above 82% within 25 years, the warranty re-insurance is provided by Lloyd’s, covering global market.
“Sunport Power’s S6 module obtains the advantages of High efficiency, High reliability, Superior warranty, High ROI, Aesthetic design and Lead-free. Different from conventional modules, S6 can be customized for shape and art design which brings more applications and possibilities to the BIPV market in need of appearance,” said Dianna Tao, vice president of Sunport Power.
