Glass glass solar panels: maximum reliability for every project

Choose glass glass solar panels when minimal degradation and maximum mechanical protection of the solar cells are required. Unlike traditional glass-foil modules, these panels feature a glass layer on both sides. This eliminates risks of moisture penetration and chemical corrosion, resulting in a solar installation that functions for decades without loss of yield. For you as an installer, this means less aftercare and higher customer satisfaction.

The technical value of glass glass solar panels in an installation

ESTG offers specific physical advantages for the installation with these modules. The construction ensures stable yield under various conditions:

• Limitation of microcracks: since the cells are located in the neutral zone of the panel, the double glass layer significantly reduces the chance of cell breakage.

• Constant performance: the modules maintain their efficiency, even under varying thermal loads.

• High resistance: these panels are better able to withstand aggressive environmental factors, such as ammonia in the agricultural sector or salty air in coastal areas.

Glass glass versus bifacial: what is the difference?

Confusion often exists between these two terms, but they indicate different properties. Glass glass refers to the physical structure and protection of the panel. Bifacial stands for the technology where the cells also capture light from the rear for extra power production. Many modern modules combine both: they have the sturdy glass glass construction and the extra yield of bifacial cells.

Long-term yield

The annual power decrease of glass glass modules is significantly lower than with glass-foil. Many manufacturers therefore offer power warranties of up to 30 years. For your customers, this means a lower LCOE (Levelized Cost of Energy) and a shorter payback period due to stable kWh production over the entire lifespan.

Resistance to extreme environmental factors

Thanks to the impenetrable glass layer on the back, the cells are optimally protected against corrosion. This makes the modules extremely suitable for locations with high mechanical stress, such as areas with heavy snowfall or strong winds. The stiffness of the panel ensures that the internal connections between the cells are less likely to be damaged.

Frequently asked questions about glass glass modules

• Are glass glass panels heavier to install? : although they have two glass layers, modern variants are often comparable in weight to standard modules due to thinner glass, keeping the load during assembly limited.

• Do these panels have a better fire rating? : yes, due to the lack of a flammable plastic back, glass glass modules often fall into a higher fire safety class, which is an advantage for specific building regulations.

• What is the difference between glass glass and bifacial? : glass glass refers to the physical structure with two glass plates for extra strength, while bifacial means the cells also capture light at the rear for a higher yield of the installation.

• What is the difference between glass glass and glass-foil solar panels? : with glass glass, there is glass on both sides, while a glass-foil panel has a glass front and a plastic back. Glass glass panels usually have a longer lifespan and better resistance to environmental factors.

• Are glass glass solar panels bifacial? : many glass glass solar panels are indeed bifacial, meaning they also use light at the rear for extra yield on a reflective surface or open setup.
