1. Double-sided power generation, doubling power generation:
Double-sided absorption of sunlight: Traditional photovoltaic modules only receive light from one side to generate electricity, while the front and back of double-sided double-glass modules are covered with glass, which can absorb sunlight reflected from the ground and scattered from the sky at the same time, effectively increasing power generation.
Significant increase in power generation: Depending on different application scenarios and ground reflectivity, the power generation of bifacial double-glass modules can be increased by 10%-30% compared to traditional single-facial modules, up to more than 40%.
2. N-type monocrystalline silicon wafer, high efficiency and low attenuation:
Higher efficiency: N-type monocrystalline silicon wafers have a longer minority carrier lifetime, which can effectively reduce electron-hole recombination, thereby improving photoelectric conversion efficiency, which is usually 0.5%-1.0% higher than P-type monocrystalline silicon wafers.
Lower attenuation: N-type monocrystalline silicon wafers have lower impurity concentrations, lower initial light-induced attenuation (LID) and higher long-term power generation stability, about half that of P-type monocrystalline silicon wafers.
Better temperature coefficient: The temperature coefficient of N-type monocrystalline silicon wafers is generally -0.29%/°C, which is better than -0.4%/°C of P-type monocrystalline silicon wafers, which means that in high-temperature environments, N-type monocrystalline silicon wafers The components lose less power.
3. Double glass packaging, reliable and durable:
Higher mechanical strength: Double-glass packaging uses a two-piece glass sandwich structure. Compared with traditional backplane packaging, it has higher mechanical strength and can better withstand the impact of severe weather such as hail and sand.
Better weather resistance: Glass materials have excellent weather resistance and corrosion resistance, and can maintain excellent power generation performance for a long time even in harsh environments such as high temperature, high humidity, and high salt spray.
Better fire-proof performance: The glass material itself is a non-combustible material. Compared with traditional backplane materials, it has better fire-proof performance and can effectively reduce the risk of fire.
4. Future development trends:
Mature technology and falling costs: With the improvement of N-type monocrystalline silicon wafer production technology and large-scale production, its cost is gradually declining, and it is expected to further replace P-type monocrystalline as the mainstream silicon wafer material in the future.
Expansion of application scenarios: Bifacial double-glass modules have obvious advantages in scenarios such as ground power stations, fishery and photovoltaic complementation, and agricultural and photovoltaic complementation. In the future, they will also be expanded to areas such as building integrated photovoltaics (BIPV).
Multi-scenario intelligent application: Combined with an intelligent tracking system and an energy management system, bifacial double-glass modules can maximize power generation and improve the overall efficiency of the photovoltaic power generation system.
