The bifaciality factor in bifacial solar panels typically ranges from 70% to 90%, indicating the rear side’s efficiency relative to the front side under standard testing conditions. This factor varies depending on the type of solar panel technology used. Here are some common types of bifacial solar panels and their associated bifaciality factors:
- Passivated Emitter Rear Cell (PERC) Panels: These panels generally have a bifaciality factor ranging from 70% to 80%. They are commonly used in commercial applications and are based on p-type or n-type monocrystalline silicon cells.
- Passivated Emitter Rear Localized Diffusion (PERL) and Passivated Emitter Rear Full Diffusion (PERT) Panels: While specific bifaciality factors for these types are less frequently detailed, they typically fall within similar ranges to PERC panels.
- Heterojunction Intrinsic Thin Layer (HIT) Modules: These modules can have higher bifaciality factors, sometimes approaching 95% to 100%, which is exceptionally high and reflects their advanced technology.
- Interdigitated Back Contact (IBC) and Tunnel Oxide Passivated Contact (TOPCon) Modules: For these advanced technologies, bifaciality factors can also vary but tend to be around 70% to 90%, depending on the specific implementation.
Overall, the bifaciality factor is a key metric for evaluating the performance of bifacial solar panels and varies based on the specific technology and design used.
