The role of double-sided solar panels

Are dual-sided solar panels a good idea?

Dual-sided solar panels have the potential to produce 20 per cent more energy than traditional one-sided systems if used properly on residential rooftops, new research from The Australian National University (ANU) shows. Dual-sided – or bifacial – solar cells allow for both the front and back of the solar panel to generate power.

Are bifacial solar panels better than single-sided solar panels?

While modern solar panel performance has improved dramatically across the board, bifacial panels can generate up to 30% more electricity than traditional single-sided panels in optimal conditions. This increased production comes from their ability to capture light on both sides of the panel.

What is a dual-sided solar system?

The dual-sided design typically incorporates high-quality solar cells sandwiched between two layers of highly transparent glass, ensuring optimal light transmission and durability. Each side is protected by anti-reflective coatings and specialised encapsulation materials that enhance light absorption while providing robust weather protection.

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.
