The solar park in Donaueschingen has 4.2 megawatts of solar panels. The bifacial Topcon solar panels from the Chinese manufacturer Jolywood promise a higher yield.
The solar panels are installed vertically, because the solar panels are bificial, a higher yield can be generated.
Jolywood solar panels offer numerous advantages. The efficiency of the n-type cells is 23.5 percent, which is more than p-type products. In addition, no light-induced degradation (LID) occurs with the n-type solar panels and the annual energy consumption of the solar panels is less than 0.4 percent. This means that after 30 years, the Jolywood solar panels would still have more than 87.4 percent of their original performance. In addition, the solar panels achieve high bifaciality. Jolyowood is convinced that the n-type Topcon technology will be used much more in high-efficiency solar panels in the near future.
