Bifacial module

Bifacial modules produce solar power from both sides of the panel. Whereas traditional opaque-backsheeted panels are monofacial, bifacial modules expose both the front and backside of the solar cells. When bifacial modules are installed on a highly reflective surface (like a white TPO roof or on the ground with light-colored stones), some bifacial module manufacturers claim up to a 30% increase in production just from the extra power generated from the rear.

A bifacial solar module is a type of solar panel that can capture sunlight from both its front and rear sides. Unlike traditional monofacial panels that only absorb light from the top, bifacial panels use transparent or semi-transparent backsheets or dual glass to allow reflected light from the ground or nearby surfaces to also generate electricity.

Higher Energy Output

• Can produce 5% to 30% more energy than monofacial panels depending on installation and surroundings.

• Ideal for high-albedo surfaces (e.g., white roofs, sand, snow, or concrete).

Durable Build

• Often made with glass-glass construction, making them more durable and resistant to environmental damage like UV, moisture, and corrosion.

Improved Performance Over Time

• Lower degradation rate than conventional panels.
