A bifacial solar panel is a double-sided energy factory that transforms sunlight into electrical energy on both its top and bottom sides.
They are different from monofacial solar panels which only use one side for solar energy production. The word bifacial comes from the prefix “bi-” (meaning two), and “facial” (for face).
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 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 backsheet. This is different from conventional solar panel systems with opaque backings.
