Palikir bifacial solar panels

Why do bifacial solar panels increase power conversion efficiency?

The increase in the bifacial silicon solar cells is due to the reduction in silicon wafer thickness and the increase in the transparency of the panels. Under better albedo and proper mounting angles, a typical bifacial solar panel is expected to show 50% more power conversion efficiency than the monofacial counterpart.

Are bifacial solar panels better than monofacial?

Under better albedo and proper mounting angles, a typical bifacial solar panel is expected to show 50% more power conversion efficiency than the monofacial counterpart. Bifacial silicon solar cells are monofacial cells with a back surface opened with a dielectric passivated layer, and a polymer back cover is replaced with a transparent sheet.

What is a bifacial solar panel?

Unlike monofacial panels that only use front-side illumination, bifacial models capture additional 10-30% energy from reflected light (albedo). Their solar cells are specially arranged with wider spacing to optimize rear-side exposure, and they typically use advanced cell technologies like PERC or TOPCon for higher bifaciality factors (65-90%).

What are the benefits of bifacial solar panels?

Commercially, there are several benefits in using bifacial solar cells. As discussed earlier, the first will not add any cost to the present monofacial solar cells. Second, the minimized land usage for installing bifacial panels is almost half the surface required for monofacial solar panels.
