Bifacial solar panels are designed to capture sunlight from both their front and back sides, making them particularly effective in low-light conditions. Here’s how they perform under such conditions:
Key Features and Advantages
- Dual-Sided Light Capture: Unlike traditional monofacial panels, bifacial panels can absorb direct sunlight from the front and reflected or diffused light from the back. This allows them to generate more electricity in less sunny conditions, such as cloudy days or during early morning and late evening hours.
- Improved Low-Light Performance: Bifacial panels excel in capturing diffused light, which enhances their performance in cloudy or shaded environments.
- Enhanced Energy Yield: They can produce 5-30% more power than traditional panels due to their ability to harness light from both sides.
Practical Performance
- Real-World Experience: Some users report that bifacial panels perform about 15% better in low-light conditions compared to monofacial panels.
- Comparison to Other Technologies: While bifacial panels are advantageous in certain low-light scenarios, other technologies like N-Type solar panels or IBC full black modules might offer superior efficiency in specific low-light conditions, such as dense cloud cover or winter conditions.
Considerations for Installation
- Mounting and Environment: The effectiveness of bifacial panels can be optimized with elevated installations or reflective surfaces underneath, which increase the amount of light reflected to the back side.
- Choice of Panel Type: For locations with frequent overcast conditions, comparing bifacial panels with other advanced technologies like N-Type or IBC full black modules can help determine the most efficient choice.
