How to Optimize the Performance of Bifacial Solar Panels

Bifacial solar panels are a type of solar panel that can generate electricity from both the front and back of the panel. This makes them potentially more efficient than traditional solar panels, which only generate electricity from the front. However, the performance of bifacial solar panels can be affected by a number of factors, including the albedo of the ground, the tilt angle of the panels, and the spacing between the panels.

A new study by researchers at the University of Ghana has analyzed the performance of bifacial solar panels under different conditions. The researchers found that changing the albedo of the land-based system can increase the bifacial gain from 5.25% to 14.5%. The albedo is a measure of how reflective a surface is. A higher albedo means that more sunlight will be reflected back onto the back of the panels, which can increase their efficiency.


The researchers also determined the optimum tilt angle for bifacial land-based PV and FPV systems to be 15%. The tilt angle is the angle at which the panels are tilted towards the sun. A higher tilt angle will allow the panels to capture more direct sunlight, but it will also reduce the amount of reflected sunlight that reaches the back of the panels.

With these changes, the bifacial gain can be increased by up to 9.25%. Bifacial gain is the difference in electricity generation between bifacial and monfacial solar panels.


The study's findings could help to improve the design and installation of bifacial solar panels, making them a more attractive option for renewable energy generation.
