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.

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.
