Benefits of glass-glass modules
The usual structure of PV modules is a laminate consisting of a sheet of tempered glass 3 to 4 mm thick on the front side, and a flexible polymer sheet on the back side. To ensure sufficient rigidity an aluminum frame must be added. Today however, industrial techniques make it possible to temper thinner glass, which makes it possible to produce panels composed of a double layer of glass without being too heavy, and rigid and solid enough to not need an aluminum frame. The double-glass module structure offers many benefits compared to the traditional glass-backsheet structure.

Benefits of frameless panels
Installers have preferred framed panels to this day, because with the mounting systems available on the market, installation is simpler and faster than for frameless panels. In addition, with the photovoltaic industry heavily focused on standardization and mass production, framed panels have established themselves as the market standard. This is obviously a shame for investors and operators of solar power plants, who cannot benefit from the objective advantages of frameless panels.
Based on this observation, Suncell has developed different mounting systems suitable for frameless panels, which allow rapid, safe and economical mounting of this type of panel.
Over the past 12 years the photovoltaic industry has been able to improve the efficiency of photovoltaic modules thanks to technological advances with an average increase of 1.5% per year. In this perspective the appearance of bifacial panels represents a real disruption. By using the same stable crystalline cell technology, and simply making the 2 sides photosensitive, you can get up to 35% more electricity with what is known as Bifacial Boost. However, the module must be mounted in a specific way in order to take full advantage of the bifacial boost.

Our colored BIPV PV modules are made with Kromatix frontglass. Kromatix glass is supplied bySwissINSO, a pioneer in the development and application of new solar technologies and products targeted at enhancing the aesthetics and overall efficiency of Building Integrated Photovoltaic and Thermal solar energy solutions.
A multi-layered nanometric coating is deposited on the inner glass surface by low pressure plasma processes. Its constitutive materials are exclusively characterised by high solar transmittance, minimal absorption (no pigments or dyes, meaning that the coloured glass will not fade out with time and sun exposure) and high durability.
The coloured appearance results from the reflection of a narrow spectral band in the visible part of the solar spectrum. The rest of the solar radiation is transmitted to the solar panel to be converted into energy. The coloured coating stacks are optimised to offer the best compromise between colour intensity and solar panel efficiency (solar transmittance above 85%).
Kromatix glass is available in 10 different shades of color.
