A bifacial solar module is a type of solar panel that generates electricity from both sides. The front side captures direct sunlight, while the back side absorbs reflected sunlight from the ground or surrounding surfaces, increasing overall energy generation.

Traditional monofacial panels only capture sunlight from the front. Bifacial panels use transparent back sheets or glass to allow sunlight to reach the rear side, improving efficiency by approximately 5–30% depending on installation conditions.

• Higher energy yield (5–30% more than monofacial)
• Better performance in diffuse and low-light conditions
• Longer lifespan with double-glass design
• More efficient use of available space
• Lower cost per unit of energy over time

Bifacial solar panels perform best when installed in areas where sunlight can reach both the front and rear surfaces of the module.

• Highly reflective surfaces such as white rooftops
• Snow, sand or water surfaces
• Elevated mounting structures
• Open ground-mounted solar farms
• Rooftops with sufficient clearance

Yes. Bifacial modules can be installed on regular rooftops. However, the additional energy generated from the rear side depends on the surface below the panels.

Reflective or light-colored rooftops can provide greater rear-side energy generation, while dark rooftops generally provide a lower rear-side gain.

On average, bifacial solar modules can generate approximately 5–20% more energy than traditional panels. Under ideal conditions, such as snow-covered ground or highly reflective surfaces, the additional energy generation may reach up to 30%.
