Frequently asked questions about glass-glass solar modules:

Glass-glass solar modules offer several key advantages compared to conventional modules with a film back:

Longer service life: The additional glass layer protects the sensitive solar cells better from moisture, UV radiation and mechanical influences. This leads to a significantly longer service life of up to 30 years, which in turn increases the profitability of the investment.

Higher performance: Glass-glass modules can withstand higher operating temperatures without sacrificing performance. This is particularly advantageous in warm and sunny regions, as energy savings can increase significantly.

Improved aesthetics: The smooth glass surface appears more modern and higher quality than the foil back of conventional modules. This can significantly improve the appearance of the roof and increase the value of the property.

Higher snow load: Due to their robust construction, glass-glass modules are significantly more stable and can therefore withstand higher snow loads than conventional modules. This is particularly important in snowy regions where traditional modules can be damaged by snow loads.

Hail protection: The additional glass layer offers improved protection against hailstones. Hailstorms can cause micro-cracks in the solar cells and permanently affect the performance of the modules. Glass-glass modules are significantly more resistant to hail and therefore offer greater security.

Other advantages: In addition to the points mentioned above, glass-glass solar modules offer other advantages, such as lower susceptibility to PID (Potential Induced Degradation) and improved recyclability.

Disadvantages: Glass-glass modules are slightly more expensive to purchase than conventional modules. However, the higher cost is offset by the longer lifespan, higher performance and lower maintenance costs over the years.
