Jolywood (Suzhou) Sunwatt Co. Ltd. (Jolywood) has unveiled two bifacial paving PV modules, boasting integrated power of 530W with efficiency 25.4%. The new products, the JW-HT&HD Series Ultra High Efficiency Paving Module and JW-HF Series Ultra Light Flexible High Efficiency Module boast a front power of 430W, efficiency of 20.5%, as well as a rear power gain of 30%. The flexible high efficiency module weighs 3.75kg/m2.
The two high efficiency modules are designed for distributed PV power generation systems and will drive the development of the distributed power generation, said President of Jolywood, Lin Jianwei.
The N-type monocrystalline high efficiency bifacial paving module developed by Jolywood uses flat ribbons to link up each cell, which avoids cells being covered by ribbons and narrows the distance between cells. The result, according to Dr.Liu Zhifeng, co-COO of Jolywood (Taizhou) Solar Technology Co. Ltd, is an increase in conversion efficiency and a reduction in the levelized cost of electricity (LCOE).
Compared to modules with the same cells, the N-type monocrystalline high efficiency bifacial paving module enjoys a power gain of 15W to 20W, increasing the conversion efficiency by 1.5%. In addition, the combination of the paving technology and the N-type TOPcon technology leads to a range of advantages for bifacial modules. Compared to monofacial modules, bifacial modules can generate an additional 10% to 30%. There is no potential induced degradation (PID) and zero light induced degradation (LID); the weak light response is better,” said Liu.
Due to the advanced composite encapsulation materials, the JW-HF Series Ultra Light Flexible High Efficiency Module has flexibility that is a perfect match for curved modules. It also weighs 70% less than products of its kind. Light and flexible, it can be used in a variety of situations, such as a rooftop with low load-bearing capacity or the exterior of a building. Additionally, it is convenient to install.
“During the past year, Jolywood has put a lot of effort into R&D and innovation for distributed power generation systems and there are some accomplishments especially in installation. The light and flexible modules will allow quick and easy installation that saves materials and reduces the cost of labor. Jolywood is applying for a patent for the innovative installation system, which makes distributed power generation widely accessible,” said Lin.
