Bifacial solar modules offer many advantages over traditional solar panels. Power can be produced from both sides of a bifacial solar module, increasing total energy generation. 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. Balance of system (BOS) costs are also reduced when more power can be generated from bifacial modules in a smaller array footprint.

If you knew there was a solar panel system for your home that delivered up to 50% more solar power compared to conventional solar panels, would you be interested? Then look no further than bifacial solar panels.

A bifacial solar panel is a double-sided energy factory that transform sunlight into electrical energy on both its top and bottom sides.

Bifacials are equipped with solar cells on both the top and the rear of the panel. They are usually monocrystalline, although polycrystalline can be used. Because they are slim, they resemble thin-film solar panels. Bifacial solar panels are frequently frameless, too.

The top of each solar module is covered in protective glass. The flipside may be glass or a clear back sheet. This is different from conventional solar panel systems with opaque backings.

Here’s a summary table that illustrates the differences in solar cell efficiencies between the major commercial options.
