Risen Energy Co., Ltd., a leading solar module manufacturer in China, just 
concluded its press conference in Ninghai, Zhejiang province, for the launch of 
the latest lineup of building-integrated photovoltaic (BIPV) products, which 
included Super Top, Super Tile alongside its latest heterojunction (HJT) 
offering, Hyper-ion. The entire lineup boasts further reduction in carbon use 
and improved power generation performance, vastly widening the opportunities 
for the development and implementation of BIPV and HJT products.

Super BIPV leads in delivering "green" roofs

Every industry in China has jumped on the carbon reduction bandwagon in light 
of the Chinese government setting carbon peaking and carbon neutrality goals. 
In 2021, the government rolled out a series of carbon reduction policies 
specifically targeting the building and construction sector, to encourage the 
construction of greener and low-carbon buildings and environments and to 
prepare the sector for the arrival of the carbon peak and carbon neutrality 
era. In response to the policies, Risen Energy, in its role as a leader and 
pioneer in all things photovoltaic, launched two key products, the Super Top 
for the roofs of industrial and commercial buildings and the Super Tile for 
residential rooftops. The two products hit all the high notes in terms of being 
a proponent of the drive to populate China with green and 
environmentally-responsible housing stock: they are safe, reliable, economical, 
diverse in the applicability, easy to install and aesthetically pleasing in 
appearance.

Super Top's unique feature is a new assembly method for the steel plate and the 
PV module so that the modules seamlessly blend in with the colors usually 
adopted by the steel industry and can be fully integrated into the construction 
process rather than bolted on after the fact. The module boasts new 
double-glass frame-free modules with 210mm wafers. The 210+ double-glass 
ensures high power generation capacity, the edgeless frame prevents the 
collection of dust on top of the unit, and the 210+HJT cell delivers a 7 per 
cent power generation gain. The module is 740W and comes equipped with 
360-degree upright locking, is waterproof and exhibits no shading loss, 
notching the power generation gain up another 1.5%.

Turning to the module's aesthetics, Super Top comes with optional 
aluminum-zinc- magnesium or color coated steel plates and customized colors to 
satisfy end-user preferences. The installation is simple and fast and can be 
completed by one person, while operation and maintenance post-installation is 
minimized. The corrosion resistance design of the product itself and excellent 
wind and fire resistance mean longer periods between each maintenance check, 
delivering a safe and worry-free experience.

The 1817mm*420mm Super Tile comes in a variety of colors and shapes that 
perfectly match household roof systems. The module has a maximum power of 120 
watts and a dust-free design that enhances power generation efficiency by 5%. 
Like Super Top, installation is easy and fast and can be completed by one 
person, leading to a saving of 30% in construction costs.

Super Tile comes in two formats, "stacked" and "tile" to meet diverse end-user 
preferences. The cost is basically equivalent to that of a household 
distributed system and the roof tiles that would have taken up the same space. 
With effectively no change in cost compared to older solutions, the low-carbon 
Super Tile better meets current market demand.

Hyper-ion boosts the green value of HJT products

Keeping costs under control has always been a challenging problem that, to 
date, has stood in the way of HJT technology going mainstream. Based on leading 
technologies in semiconductor physics, semiconductor packaging, basic materials 
and equipment design, after thousands of iterations, Risen Energy finally 
launched a product that it can be proud of. The new product— Hyper-ion cell 
uses 210 HJT half-cut 120 micron and microcrystalline technology, achieving a 
super high efficiency exceeding 25.2%. Basing the calculation on a 100MW 
project in Hainan province, the long-term power generation of an HJT solution 
has the advantage of reducing LCOE by more than 10% and possibly even more when 
comparing both the one-time investment costs and ongoing overhead associated 
with traditional processes.

Relying on advances in passivation technology, the unit comes with an open 
voltage above 750mV and ultra-thin wafers that are quite a bit less thick than 
TOPCon and PERC, as well as HJT thin cells with carbon value nearly 30% lower 
than that of PERC. Using a high strength alloy steel frame, Hyper-ion's carbon 
footprint score is reduced from more than 570 per kw to less than 400 without 
the application of special silicon materials, and can be notched down even 
further, to nearly 300 when special silicon materials are used. These are 
highly enviable benchmarks in the ultra-low carbon sector.

Risen Energy's HJT modules perform at 5 times the norm required by the IEC test 
specifications, while the carbon footprint score certified by a third party 
standing at less than 400. When applying the carbon footprint approach, the 
potential premium for Hyper-ion can reach 0.01 yuan per watt based on the 
current price of European carbon emission rights at around 80 euros per ton.

Risen Energy plans to focus mainly on research into low-carbon series products, 
including further R&D into BIPV, steel frame and HJT technologies, with the 
goal of launching more low-carbon products, further building out the 
photovoltaic "low-carbon universe", facilitating green and sustainable 
development, and accelerating the transition to a zero-carbon era.
