Bifacial solar modules convert sunlight into electrical energy on both the front and back. The solar cells are light-sensitive on both sides and embedded in transparent carrier materials such as glass. Thanks to this design, the modules also use reflected light from the ground or from the surroundings - a clear advantage over conventional monofacial modules.
Bifacial modules consist of double-sided active solar cells that are embedded between two panes of glass or in a glass-plastic composite. The rear side is translucent. Depending on the substrate - e.g. concrete, gravel or snow - reflective light can additionally activate the rear side and increase the total energy yield by up to 30 %.
The major advantage of bifacial modules is their higher specific energy yield, particularly with reflective substrates and optimum mounting angles. They offer improved area utilization, higher efficiencies and are particularly resistant to environmental influences. Even in diffuse lighting conditions or when the sun is low, they provide additional energy and thus increase overall efficiency.
Bifacial modules are preferably used in ground-mounted systems, on flat roofs with a reflective substrate or in agricultural PV systems. They also achieve good yields on carports or systems with an east-west orientation. They are particularly suitable where sufficient light is reflected from behind and the highest possible total output per area is to be achieved.
* By applying the Tenka Nanotech layer, 15/20 watts more power is generated compared to the standard cell.

Tenka Orion technology redefines efficiency in photovoltaics. At its heart is the patented Nanotech coating, which enables an exceptionally high light yield thanks to millions of tiny prisms on the cell surface. Even weak or diffuse light is efficiently captured and converted into electricity - a clear advantage in changing weather conditions or limited light incidence.
Tenka Orion modules achieve measurably higher energy yields than conventional modules, particularly at off-peak times and when the sky is overcast. This technology maximizes the energy yield per square metre and makes roofs with limited space economically viable. At the same time, it reduces installation costs as fewer modules are required for the same output.
The combination of nanotechnology and high-quality cell architecture makes Tenka Orion an ideal solution for all areas of application - from private house roofs to large open-space systems. The optimized use of light noticeably extends the daily generation time, which creates significant additional yields, especially in the morning and evening hours.
Tenka Orion technology also impresses with long-term use: low degradation, high material quality and constant performance ensure long-term investment security. Tenka Orion modules thus set new standards for sustainable and powerful PV systems - both technically and economically.
