Glass-foil or glass-glass solar panels?
There are two types of solar panels: glass on glass and glass-foil
Solar panels convert sunlight into sustainable energy. This is how you can fulfil your own power needs. Solar panels are often applied on the roof and form the heart of a solar-energy system. There are two basic types of solar panels: glass-foil and glass-glass solar panels. These solar panels differ in material, capacity, lifespan and quality.
In order to make the right choice, it is important to compare the two types.
Traditional glass-foil solar panels are made of tempered glass on the front of the panel and plastic film composite (plastic) on the back. Solarwatt glass-glass solar panels feature a glass plate on both sides of the panel, which protects the solar cells much better from environmental factors such as heat and moisture.
Benefits of Solarwatt glass-glass solar panels
Better protection and lower degradation
As the double glass layer provides much better protection, the solar cells on glass-glass solar panels will degrade 40% slower than in glass-foil solar panels. As solar cells are ageing, their capacity will reduce every year. So this will go twice as fast when using glass-foil solar panels.
Longer lifespan and higher yield
Better warranty conditions
Ultra-hard glass. Twice.
Like a breeze through every storm.
Our high-efficiency solar cells are embedded in a composition of two layers of EVA film and thermally hardened glass. This ensures that they can withstand mechanical forces such as hail, snowfall and most other external influences.

Where do I place solar panels?
Solar panels can be attached in different ways. Solarwatt develops solar modules for various situations. For example, in addition to solar panels for roofs, we also have special solar panels for use in carports, verandas and facades.
Solar panels on the roof
Most solar panels are mounted above the roof tiles on aluminum profiles. Solar panels can be placed on a pitched roof or a flat roof.
Solar panels as carports
Solarwatt also has a solution for use on carports and facades. There is no protective layer between man and solar panel, as is the case with a roof. The special safety glass ensures that the solar panel breaks safely if, for example, a stone hits it.
Pioneer in climate protection.
We are the world’s first system manufacturer in the solar industry to offer its customers the option to offset supply chain carbon emissions for selected glass-glass panels.
Glass-glass solar panels provide optimal security and performance.
