Double-sided effect of solar modules

Can a double-sided solar panel be attached back-to-back?

In this work, a double-sided solar panel (bifacial solar cell configuration) comprising of two silicon PV panels attached back-to-back was investigated. The module was fixed on an adjustable ground mounted frame and the tilt angle was varied to be (30º, 45º, 60º, and 90º).

How do bifacial solar panels work?

Traditional solar panels, known as monofacial panels, only use one side of the module for this process. The light that isn’t absorbed by the panel is reflected away. Bifacial solar panels are different. These types of panels have solar cells on both sides, enabling them to absorb light from the front and the back.

Can bifacial solar panels increase power generation?

The current research shows that the bifacial panels can increase the power generation by up to 25% depending on the surrounding infrastructure . The paper used the MATLAB engineer tool to determine the solar radiation that reaches the front and back panels.

Why are bifacial solar modules difficult to install?

The design and positioning of the junction box are some of the most challenging aspects of bifacial solar module installation. The module's rear side causes undesirable shadowing, affecting energy yield when junction boxes are placed in areas sensitive to illumination . This can result in a bifacial PV cell electrical mismatch.
