Explained: Bifacial Solar Panels
The traditional monofacial solar panels have an opaque backsheet. On the other hand, bifacial solar panels have a reflective back or dual panes of glass holding the solar cells in place for absorbing the solar energy from both the surfaces. The panels are completely transparent, and are usually frameless without metal gridlines.
