Product Introduction
Double-sided solar panels
1. Working principle
Double-sided solar panels generate electricity by absorbing light from both sides:
1. Working principle
Double-sided solar panels generate electricity by absorbing light from both sides:
- Front side: Directly captures sunlight, with conversion efficiency similar to that of single-sided panels.
- Back side: Utilizes reflected light from the ground or other objects (albedo light) to generate electricity, improving overall efficiency.
- Bifacial ratio: The ratio of the back side's power generation efficiency to the front side's (mainstream technology achieves 65%-80%).
2. Core Advantages
- Increased power generation: 10%-21% higher than single-sided panels, particularly suitable for high-reflectivity environments (such as deserts, snowfields, and water surfaces).
- High Stability: Lower degradation rate (0.5% vs. higher for single-sided panels), with a warranty period extended to 30 years.
- High Space Utilization Rate: Can be installed vertically, suitable for scenarios with limited roof area.
3. Application Scenarios
- Highly Reflective Environments: Highly effective in areas with high reflectivity such as deserts, water surfaces, and snowy regions.
- Urban Roofs: Vertical installation balances power generation and space utilization.
