We installed two 110/50W bifacial solar panels and a Plasmatronics PL40 solar regulator on this large Winnebago motor home.

The solar panels are spaced above the white roof to allow light travelling around and through the solar panels to reflect onto the rear surface of the bifacial panel to produce additional power. The space also allows air flow under the panel to reduce operating temperatures and increase power output.

The 12V bifacial panels used in this installation are each rated at 110W on the front face and 50W on the rear face. An installation such as this is able to produce slightly higher daily cumulative power figures than the standard single sided solar panels.
