Bifacial Solar Panels

Bifacial solar panels and bifacial 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 also more durable because both sides are UV resistant, and potential-induced degradation (PID).

Types of bifacial modules

Bifacial modules come in many designs. Some are framed while others are frameless. Some are dual-glass, and others use clear backsheets. Most use monocrystalline cells, but there are polycrystalline designs as well. The one thing that is constant is that power is produced from both sides.

How Bifacial Is Installed?

The way a bifacial module is installed depends on its type. A framed bifacial panel might be easier to install than a frameless, just because traditional mounting and racking systems are already adapted to framed models.

For frameless bifacial or glass-glass solar modules, the module clamps will often feature rubber guards to protect the glass, and special care must be taken to prevent overtightening bolts and damaging the glass.

The higher a panel is tilted, the more power it produces from its bifacial properties. Bifacial modules mounted flush to a rooftop block any reflected light from reaching the backside of the cells. That’s why bifacial solar panels perform better on flat commercial rooftops and ground-mounted arrays, because there is more room for tilt and bouncing reflected light to the rear of the modules.
