The double-glass construction of bifacial solar panels significantly enhances their durability through several key factors:
- Resistance to Mechanical Loads: Double-glass panels have equal thickness on both front and rear sides, which minimizes compressive or tensile stress on the solar cells. This robust design allows them to withstand harsh conditions and various installation types without compromising performance.
- Thermal Stress Reduction: Both glass layers expand and contract at the same rate in response to temperature changes, reducing the stress on the embedded solar cells. This consistent thermal behavior helps maintain the integrity of the cells, ensuring they last longer.
- Protection from Environmental Factors: The double-glass design provides superior protection against humidity, ammonia, salt spray, and even fire, making the panels more durable and safer for long-term installations. This enhanced protection also reduces degradation from environmental exposures.
- Structural Stability: Despite sometimes using thinner front glass, the total thickness of approximately 4 mm of glass maintains stability and protects the solar cells, contributing to a longer operational lifespan and higher overall yields.
Overall, the double-glass construction in bifacial panels enhances durability by providing mechanical strength, thermal stability, and environmental protection, making them more reliable and resilient than traditional panels.
