Monofacial solar modules only use the front side to generate electricity. The solar cells are only sensitive to light on one side and are embedded in a stable, opaque backsheet. This technology has been in use for decades and forms the basis for the majority of photovoltaic systems installed worldwide. Monofacial modules are robust, readily available and technically mature - a reliable standard in solar technology.

The modules consist of crystalline solar cells (usually PERC or TOPCon), which are protected by tempered glass on the front. The back is usually covered with plastic or glass, but is not translucent. This means that only the front can absorb sunlight and convert it into electrical energy. This clear focus on one active side considerably simplifies production, installation and system integration.

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 %.

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.
