How Tranparent Are Bifacial Solar Panels

Partially transparent solar panels.

How tranparent are bifacial solar panels.

Jinko solar swan bifacial hc. Figures 1 and 2 show the purpose of the transparent conductive tubes there are two types of tubes yellow and blue which are used to connect the pv cells with each other as follows. Figure 1 3d side view of parabolic bifacial solar panel figure 2 3d cut sectional front view of the parabolic bifacial solar panel. Compared to the conventional solar pv cells the partially transparent solar panels have a lower efficiency at 7 2.

Bifacial solar panels have their backs covered with either a transparent sheet or a have a double glass panel. Here is a diagram of a side view of a bifacial. Because they are slim they resemble thin film panels. 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.

Bipv applications demand flexibility in the pv module having both an aesthetic and functional role. The hc in the product name indicates that the swan bifacial makes use of half cut solar cells to improve efficiency in the shade it is available with both opaque and transparent backsheets for those applications where aesthetics are critical. The top of each solar module is covered in protective glass. The flipside may be glass or a clear backsheet.

Transparent solar panels and modules semi transparent solar modules. The ideal use case for bifacial solar panels is in commercial and utility scale solar installations especially those that utilize solar trackers. A german manufacturer heliatek gmb has developed this partially clear solar panel which can absorb about 60 percent of the sunlight it receives. This makes reflection possible hence there is energy production from both sides increasing the total power output.

In a recent study conducted by longi a solar panel manufacturer bifacial panels yielded 11 percent more energy than standard solar panels in a tilted ground mounted solar installation in china. Power can be produced from both sides of a bifacial module increasing total energy generation. This is different from conventional solar panel systems with opaque backings. Bifacial solar panels are frequently frameless too.

Bifacial solar modules offer many advantages over traditional solar panels.
