Bifacial modules produce solar power from both sides of the panel. Whereas traditional opaque-backsheeted panels are monofacial, bifacial modules expose both the front and backside of the solar cells. Bifacial solar modules offer many advantages over traditional solar panels. Power can be produced from both sides of a bifacial module, increasing total energy generation. They're often more durable because both sides are UV resistant, and potential-induced degradation (PID) concerns are reduced. Balance of system (BOS) costs are also reduced when more power can be generated from bifacial modules in a smaller array footprint. When bifacial modules are installed on a highly reflective surface (like a white TPO roof or on the ground with light-colored stones), up to a 30% increase in production can be gained just from the extra power generated from the rear. Bifacial modules are the future of the industry.

Power output characteristics - temperature and irradiance


Solar panels are fed by direct Sunlight, however, they perform better in colder ambient temperatures. All Datasheet values are measured under standardized 20°C. The graf shows the behavior of the panel in warmer areas. Panel losses part of its output efficiency, but is well suited even for extremely hot areas.

Panel behaviour under different Temperature

Like with temperature, the Datasheet values are stated at standardtized value of irradiance at 800 W/m2, to roughly calculate actual power output in your area, find the avarage irradiance and compare with the graf.

30 years Warranty


The manufacturer provides up to 30-year Warranty for remaining Power output. The warranty is calculated linearly year by year.

The warranty in detail:

  • 12 years Product Workmanship warranty
  • 12 years Minimum 92% Power Output
  • 30 years Minimum 83% Power Output

The long warranty period is possible by quality inspection and testing during production. The manufacturer hosts testing laboratory used to confirm TUV, Ul, CSA, ETL, SGS and CGC certifications. They also use this laboratory to ensure their product meet the highest standards.

  • All panels tested one by one during production
  • The production process inspected and monitored
  • Verified parameters recorded for customer reference
  • Fast replacement of defective products
  • Insurance from global insurance company
