Next2Sun GmbH has announced that its in-house developed vertical installation 4.2MW photovoltaic power station project in Donaueschingen, Germany has been successfully connected to the grid. The most important feature of the project is the vertical installation of the PV industry’s most advanced n-type bifacial modules which, when compared with traditional installation methods, enables a solar plant to gain a higher energy yield. 

Jolywood, as the world’s largest manufacturer of n-type PV products, is Next2Sun’s exclusive partner for the provision of n-type bifacial solar modules.  Speaking of the cooperation with Jolywood, Mr. Hildebrandt, Next2Sun’s CEO, said: “We have been following Jolywood for a long time and know their products very well. Their latest n-type TOPCon bifacial technology is the most suitable for a vertical bifacial installation, as high efficiency on the rear side (high bifaciality) is perfect to achieve the best possible yield. We selected Jolywood to be our partner after careful consideration and contact with many module manufacturers. Jolywood’s leading position in n-type technology and the advantages of n-TOPCon modules were the main reasons for our decision, but we have also been very impressed by Jolywood’s professional service system, even in the face of the Covid-19 pandemic, during which they have still been able to achieve on time delivery.  In the future, we will continue to cooperate with Jolywood to develop more photovoltaic projects.” 

As the world’s leader in n-type TOPCon bifacial technology, Jolywood has been focused since 2016 on the research into and development of n-type technology, including nPERT, n-TOPCon, IBC and TBC. Dr. Zhifeng Liu, Jolywood’s GM, said: “Compared with p-type modules, n-type modules have very obvious advantages. First, the average mass production conversion efficiency of Jolywood’s n-type modules can be as high as 23.5%, which is much more efficient than traditional p-type modules. Second, n-type modules have no LID, and annual degradation is below 0.4%, which means yields will be more than 87.4% after 30 years. In addition, n-type modules have much lower rear shading loss which contributes to their high bifaciality. There are still many other technological advantages with n-type modules, such as better low light performance and lower temperature co-efficiency. As p-type cells and modules are facing difficulties in meeting the increasing demand for higher efficiencies, N-type TOPCon technology will dominate high-efficiency solar cell technology in the near future and Jolywood will continue to launch new products to meet changing customer needs.”
