Bifacial Solar Panels: Key Benefits
Increased Energy Production
Because bifacial panels absorb sunlight on both sides, they can generate 5-30% more power than traditional panels. This is especially pronounced in environments where reflected or diffused light is abundant, such as snowy areas, white rooftops, or surfaces with high albedo. When combined with tracking systems, energy gains can rise to 30-40% compared to conventional panels.
Better Low-Light and Diffuse Light Performance
These panels perform better under less sunny conditions by capturing diffused and reflected light, which extends their operational hours during the day.
Higher Lifetime Energy Yield
The increased power production translates to a higher overall energy yield over the panel’s lifetime, improving return on investment and energy generation efficiency.
Durability and Longer Lifespan
Most bifacial panels feature a robust double-glass construction, enhancing their resilience and often resulting in longer warranties and operational lifespans compared to traditional panels that use a glass front and a polymer backsheet.
Versatility and Space Efficiency
Their ability to produce more energy per unit area makes bifacial panels especially advantageous in space-constrained installations. They are versatile enough for ground mounts, rooftops, and carports. Additionally, their sleek, transparent double-glass design offers enhanced aesthetics, fitting well in architectural applications.
Potential for Lower Levelized Cost of Energy (LCOE)
The improved energy output and durability contribute to a reduced LCOE, making bifacial panels economically attractive over time.
