Bifacial glass photovoltaic is a special design of photovoltaic panels, which adopts a structure where two glass panels are clamped between photovoltaic cells. This design enables the photovoltaic panels to absorb light from both sides simultaneously, thereby enhancing the photoelectric conversion efficiency. When sunlight shines on the double-sided glass photovoltaic panels, the light passes through the transparent glass panels and reaches the photovoltaic cells, which convert light energy into electrical energy. Due to its double-sided design, even when one side is insufficiently illuminated, the other side can continue to absorb light for power generation.
1. Advantage
A. Power generation gain: Backside power generation can increase the total output of the system, especially in high-reflection environments (snow, sand, white roofs).
B. Long service life: The double-glass structure is corrosion-resistant and has no PID risk, with a service life of over 30 years.
C. Anti-hidden cracking: The glass support reduces the mechanical stress of the battery cells.
D. Bifaciality rate: The bifaciality rate of high-quality double-sided glass modules can reach 70% to 90% (back efficiency/front efficiency).
2. Application scenarios
A. High-reflectivity environments: snow, deserts, beaches, etc.
B. Distributed power stations: Agriphotovoltaic complementary systems, carports, building facades (BIPV).
C. Tracking bracket system: In conjunction with a single-axis tracker, it maximizes the benefits of bifacial power generation.
