SolarWorld 280Wp DUO Bisun Mono Solar Panel

The new Sunmodule Bisun delivers high yields all-round: It is a solar module active on both sides that converts light from all directions into electrical energy. This ensures up to 25 % more yield per installed kWp. Thanks to the use of the newest glass technologies, it also has a particularly long lifespan and high mechanical durability.

Product Benefits

  • Up to 25% more yield with innovative bifacial technology.
  • Higher returns with shorter amortization time.
  • Extremely long lifespan using glass on the front and rear sides of the module.
  • 30-year linear performance guarantee – at least 86.85 % output after 30 years.

Product Description


Bifacial Cell Technology
The duo cells used in this module contribute to power generation through their active rear side. The double-sided light utilization, the so-called bifaciality, is based on the further development of PERC cell technology, which we deploy in serial production for more than 2 years. The Sunmodule Bisun also has an exceptionally long lifespan using glass on the front and rear sides of the module. This glass-on-glass technology also ensures high mechanical durability and improved degradation behaviour.

Functioning of the SUNMODULE BISUN Project
DUO Bisun Mono Solar Panel

Optimum on a large scale
The Sunmodule Bisun is particularly suitable for ground-mounted systems and flat roofs. If the solar module is used on surfaces such as light-coloured concrete or white membrane, more light is reflected into the module and the energy yield increases further. The brighter the surface, the higher the output generated. However, the bifacial module also produces more output than comparable standard modules on non-optimized surfaces such as grass, sand or trapezoidal sheeting.
