Bifacial Solar Modules are an important innovation in photovoltaic technology. They can generate electricity by absorbing light energy from both the front and back sides, significantly improving system efficiency. The following is a detailed introduction of working principle and core advantages
1. Working principle
A. Bifacial light reception: Traditional modules only generate electricity from the front side. The back side of bifacial modules uses a transparent backplane or a double-glass structure (instead of an opaque backplane) to absorb reflected light (such as grass, snow, sand, etc.) or diffuse light from the ground and surrounding environment.
B. Photoelectric conversion: The front and back sides of the cell (such as PERC, HJT, TOPCon and other bifacial cells) have the ability to generate electricity. The efficiency of the back side is usually 60%~90% of the front side efficiency.
2. Core advantages
A. Increased power generation: Depending on the installation environment, bifacial modules can increase power generation by 5%~30%.
B. Reduced LCOE (levelized cost of electricity): Higher power generation per unit area dilutes system costs.
C. Enhanced durability: The double-glass structure (2mm glass + 2mm glass) is PID-resistant, corrosion-resistant, and sand-resistant, with a service life of more than 30 years.
D. Better temperature coefficient: Double-glass has good heat dissipation, and the performance degradation in high temperature environments is lower than that of traditional modules.
