Bifacial solar panels are generally more durable than monofacial panels. This is primarily because bifacial panels are constructed with tempered glass on both sides (dual-glass design), whereas monofacial panels typically have a glass front and a polymer backsheet, which is less durable over time.
The dual-glass structure of bifacial panels offers superior protection against environmental factors such as moisture and ultraviolet rays, which helps prolong the panel’s lifespan and reduces degradation rates. Consequently, bifacial panels tend to have longer warranties and extended operational lifespans compared to monofacial panels.
In summary:
| Feature | Monofacial Panels | Bifacial Panels |
|---|---|---|
| Construction | Glass front + polymer backsheet | Dual tempered glass on front and back |
| Durability | Standard lifespan; less resistant to long-term environmental stress | Higher durability; better protection against moisture and UV |
| Lifespan | Standard | Longer lifespan |
Thus, bifacial panels offer a slight but meaningful durability advantage over monofacial panels due to their robust double-glass design.
