In the ever-evolving world of photovoltaic technology, double glass solar modules are emerging as a game-changer. By encapsulating solar cells between two layers of glass, these modules offer unparalleled durability and efficiency. But what exactly sets them apart?
What are double glass solar modules?
Traditional solar panels typically feature a glass front and a polymer backsheet. In contrast, double glass modules replace the polymer layer with another glass sheet, creating a robust sandwich structure. At IBC SOLAR, we use 2,0 mm x 2,0 mm glass layers, whereas some other market offerings use thinner 1,6 mm x 1,6 mm layers. This ensures greater durability and longevity. Generally, the front and back glass layers in these modules have the same thickness, contributing to their balanced structural integrity. This design not only enhances the module’s structural integrity but also provides superior protection against environmental factors.
Key Advantages of double glass modules
- Enhanced durability
- Material resilience: Glass inherently resists aging, ensuring that modules maintain performance over decades.
- Mechanical robustness: The dual-glass structure offers exceptional resistance to mechanical loads, such as wind and snow, making them ideal for challenging environments.
- Superior protection
- Environmental shielding: Double glass modules provide excellent defense against moisture, corrosion, and UV radiation, reducing the risk of potential-induced degradation (PID).
- Thermal stability: The identical thermal expansion coefficients of the glass layers minimize stress on solar cells during temperature fluctuations.
- Increased efficiency with bifacial technology
- Dual-sided energy Capture: Many double glass modules are bifacial, allowing them to harness sunlight from both sides. This can lead to energy gains of up to 25%, especially when installed over reflective surfaces.
- Optimized performance: Bifacial modules are particularly effective in open spaces like solar parks, where ground reflectivity can be maximized.
- Sustainability and recyclability
- Eco-Friendly design: Eliminating the plastic backsheet reduces environmental impact and simplifies recycling processes.
- Longer lifespan: with a potential operational life exceeding 30 years, these modules contribute to sustainable energy production.
Potential challenges and solutions
While double glass modules offer numerous benefits, it’s essential to consider factors such as weight and installation requirements. Advancements in manufacturing have led to lighter designs, but proper handling and mounting systems are crucial to ensure longevity and performance.
