Sunport Power Optimizes S6 Flexible Module, Aiming Growing BIPV Market

PVTIME - The world's first manufacturer on GW-scale for MWT PV module, Sunport Power announced recently that the company has optimized the S6 flexible module product which aims the growing BIPV market.

Being launched in 2018 and later achieved successful production on
pilot line, S6 was continuously upgraded and optimized by Sunport
Power's R&D team with its flexibility and high-efficiency for
customers' needs in different scenarios. The module efficiency of 21.2%
has been achieved by the new upgraded S6 module. With the booming of
building integrated photovoltaic (BIPV) market, Sunport Power has
received orders from multiple overseas customers in Europe, Japan, Australia, etc.

MWT technology

The S6 Flexible Module of Sunport Power applies unique Metal Wrap
Through (MWT) technology as its fundamental. 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 15W more

MWT technology is a promising technology. Prof. Martin Green,
chief scientist of Sunport Power said: "MWT is not a merely technology,
but a platform on which many other cell technologies can be attached

Excellent features of S6 flexible module

Equipped with MWT, the S6 flexible module is known for its excellent features of light, thin, flexible and lead-free.

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

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. "In fact, with the excellent
flexibility, the light and thin S6 module is especially suitable for
curved surface, low-load capacity roofs, and facades, etc," added Tao.

Dr. Zhang Fengming, the founder and CEO of Sunport Power expressed
his ambition of S6 flexible module to press: "The marriage of S6
Flexible Module and BIPV has already begun to show its promise for the
prospective future. And this trend has no sign of slowing down in its
trajectory. In future, Sunport Power will continue trying to fulfill
diversified market needs in different segments with our advantageous
