Bifacial solar panels are generally more durable than traditional monofacial solar panels due to several key design features:
- Double-Glass Construction: Most bifacial panels use a double-glass design, with tempered glass on both the front and back sides. This construction enhances their robustness and resistance to environmental factors such as wind, hail, and UV exposure compared to the typical single-glass and polymer backsheet used in traditional panels. The dual-glass setup helps protect the solar cells better and contributes to a longer lifespan.
- Longer Warranties and Slower Degradation: The enhanced durability of bifacial panels is reflected in the warranty terms offered by manufacturers, often extending up to 30 years, with a slower degradation rate of the cells over time. This suggests a longer operational life compared to traditional panels, which typically have shorter warranties and faster degradation schedules.
- Reduced Potential-Induced Degradation (PID): The frameless or glass-on-glass design of bifacial panels also reduces the risk of PID, a common issue in some traditional panels that can degrade performance over time. This leads to more stable output and better long-term reliability.
- Better Resistance to Environmental Conditions: The use of tempered glass on both sides means bifacial panels are less prone to damage from snow, debris accumulation, and mechanical stresses. They can even be installed vertically to minimize snow and dirt buildup, a setup not feasible with traditional solar panels.
In summary, bifacial solar panels’ double-glass, frameless construction, and improved resistance to potential degradation combine to make them more durable and longer-lasting than traditional monofacial solar panels. However, this also typically comes with a somewhat higher upfront cost and may require more careful installation to maximize their benefits.
