Bifacial Solar Panels Efficiency

Bifacial solar panels can be effective in certain residential applications like pergolas and some ground mounted systems.

Bifacial solar panels efficiency.

But a newer innovation is paving the way to the next generation of module technologies that will revolutionize solar efficiency for many applications. Bifacial solar modules have the capability to generate electricity by capturing light from both sides of the module. The glass to glass structure provides the solar panels with numerous benefits namely reduction in moisture corrosion microcracking and delamination. Korean electronics conglomerate lg is currently dominating the market by offering an energy efficient bifacial module with a front system of 390 w.

With a tracking system these modules can reach up to 27 percent efficiency. While bifacial solar panels have higher efficiency ratings they aren t that much more efficient. Their neon 2 bifacial solar panels have an efficiency of up to 18 7. First off as we mentioned earlier bifacial solar panels can use reflected light to generate electricity unlike monofacial solar cells that allowed this light to go to waste.

Bifacial solar modules offer many advantages over traditional solar panels. For bifacial panels to work properly the back of the panel must remain unobstructed. The bifacial solar cell efficiency increase can be as high as 27 with a solar tracking system that tilts solar cells continuously toward the sun during its trajectory across the sky. Bifacial solar panels are considered more efficient than traditional panels mostly because they produce more energy with about the same number of parts and have the same footprint as a traditional panel.

It in turn raises the efficiency of the bifacial solar cell. This system maintains a perpendicular panel orientation toward the sun throughout the day for maximum direct exposure of the cells to radiant solar energy. Thus you can increase efficiency by up to twenty five or thirty percent. Snow white tiles or even dirt and grass can absorb this reflected light.

But for the majority of property owners considering a rooftop installation bifacial panels doesn t make sense. They re often more durable because both sides are uv resistant and potential induced degradation pid concerns are reduced when the bifacial module is frameless. Meaning these modules only have a difference of four percent more than an average premium mono facial mono crystalline module. These panels absorb sunlight from the front and rear sides via a transparent back sheet.

Bifacial solar panels are designed to improve efficiency and output more power but they come at a higher cost not only for the panels but for associated materials to mount them properly. Power can be produced from both sides of a bifacial module increasing total energy generation.
