Bifacial modules produce solar power from both sides of the panel. Whereas traditional opaque-back sheeted panels are monofacial, bifacial modules expose both the front and backside of the solar cells.
When bifacial modules are installed on a highly reflective surface (like a white TPO roof or on the ground with light-coloured stones), some bifacial module manufacturers claim up to a 30% increase in production just from the extra power generated from the rear.
Bifacial solar modules offer many advantages over traditional solar panels. Power can be produced from both sides of a bifacial module, increasing total energy generation. They’re often more durable because both sides are UV resistant. Costs are also reduced as more power can be generated from bifacial modules in a smaller array footprint.
Bifacial solar panels capture light not only from the front of the panel but also from the back. With double-sided solar panels (PV), we increase the electricity yield by about 10 to 20%. We are developing knowledge and technology for bifacial solar panels and a complete model that predicts energy yields.
Bifacial solar panels can reduce electricity costs enormously. For example, PV installations or projects produce the same amount of electricity on a smaller roof area. Also, fewer PV modules and system components are needed on the same base area, which leaves more light and rainfall available for ecology, for example.
