A bifacial solar panel is a bifacial energy factory that converts sunlight into electricity at its top and bottom.
They differ from single-sided solar panels that use only one side for solar energy production.
Bifacial panels are equipped with solar cells on the top and rear of the panel. They are usually single crystal, although polycrystalline can be used. Because they are so thin, they resemble film panels. Bifacial solar panels are also often frameless.
The top of each solar module is covered with protective glass. The reverse side can be glass or a transparent back. This is different from traditional solar panel systems with opaque backings.
Here is a side view of a bifacial solar panel:

The hardware used to mount the bifacial solar array is designed to minimize shadows. This means only very narrow support rails and only corner vertical supports.
The junction box (the electrical guts and brain of a solar panel system) that is usually located on the back is smaller than a traditional solar array. As a result, it takes up less space and has less shading from the solar cells on the back. can give you more solar energy.
