PV Module Material Showcase
The first product highlighted was the company’s latest reinforced frontsheet, which has been incorporated into the company’s new NIWA Air series of flexible PV modules. This produce comes with a rated power of 575 W and 20.9% efficiency, but the interesting part is its applications. This flexible module is promoted for specialty applications such as curved roof, camping, balcony solar and vehicle roof. Wang then quickly walked through the exhibits from Jolywood’s mainstream PV module materials. These include its latest transparent backsheet with black grid. This product, featuring a PET polymer core with FFC nano-coating on both sides, attains a light transmission rate of over 93%. The product’s performance has been validated through multiple outdoor field tests, showing less than 2% degradation after 3 years of service.
A reflective black backsheet that is black in color on the cell side to give an all black appearance, at the same time reflects the sunlight to improve optical absorption. EPE encapsulant was the highlight among the encapsulation solutions, while the company offers all varieties of encapsulants that are suitable for different cell technologies.
Steel frame modules
Regarding the mainstream module products, addressing the challenge of maintaining mechanical strength amid changes in module layout, particularly along the long side, Jolywood has introduced an innovative solution by replacing the traditional aluminum frame with a steel frame. This double-beam steel frame design offers mechanical strength comparable to conventional aluminum frames, while reducing carbon emissions by up to 45% and lowering costs. For long-term reliability, the steel frame is coated with a 25 µm layer of Aluminum-Magnesium-Zinc. The module has a rated power of 645 W and 23.9% efficiency.
Additionally, the company offers a thin-glass encapsulation solution that combines 1.8 mm-thick tempered glass with a transparent meshed backsheet and a double-beam steel frame. This design ensures mechanical durability under extreme environmental loads, such as heavy wind and snow. Furthermore, the breathable nature of the underlying backsheet helps expel acids that may form within the module lamination, thereby reducing the risk of busbar metallization corrosion. Meanwhile, the module’s lower operating temperature contributes to enhanced power generation and improved reliability. Compared to standard double-glass modules, this version is 17–20% lighter, reducing transportation costs and improving installation efficiency.
