Adding Colour to the Solar Industry
Colour treated glass for photovoltaic (PV) and thermal panel applications involves the application of highly efficient and environmentally friendly nanotechnology surface treatments optimized for solar energy (photovoltaic and thermal). This means our product has no paint or tint, but atomic deposition transforming the solar glass into colour. Kromatix™ technology offers vast new opportunities combining full architectural design flexibility and unparalleled panel aesthetics with optimum panel performance for solar building integration.
Kromatix™ can be applied to a large variety of solar powered products and technologies. For facade applications we currently experience the highest demand in Glass/Glass solar (PV) panels (slideshow) because of their superior aesthetics.
Kromatix™ is available in six colours, Grey, Blue, Blue Green, Orange, Bronze and Brass. Kromatix™ glass is the front glass layer of a solar (PV) panel and is laminated at the panel manufacturers factory. SwissINSO can deliver the glass stand alone or deliver complete coloured solar (PV) panels in various sizes and thicknesses.
Kromatix™glass is obtained by combining two different surface treatments:
- A multilayered coating is deposited on the inner glass surface by low pressure plasma processes. Its constitutive materials are exclusively characterized by high solar transmittance, minimal absorption and high durability while maximizing high angular colour stability. No pigments or dyes (paint) are used so that the colour does not fade out with the passage of time or due to sun exposure.
- Treatment of the outer glass surface results in diffused reflection. This prevents glare effects and reinforces the masking effect of the solar devices technical parts, further enhancing aesthetics.
The colours of nature all around us are produced by different aspects of the interaction of light with matter. The most common is light interacting with coloured pigments and dyes which absorb and reflect certain light wavelengths. Colour has however sometimes a purely physical origin as created by diffraction or interference of light. It is a known fact that many butterflies obtain their colour thanks to interference phenomena.
Applying this technique to solar glass a good compromise has to be found, as the higher the reflectance, the lower the transmittance and the energetic performance of the solar device on which the coloured glass cover is installed. This is why the colour changes as the angle changes.
Kromatix™ and Solar Panel Performance
The IFT Certified Kromatix™ Solar Glass is available in various colours. There are no paints nor tints used to colour the glass therefore it remains stable with time and sun exposure and thanks to the unique Kromatix™ technology average transmittance is between 85% and 90% colour depended. The colored solar glass is produced in various dimensions and thicknesses, can be processed in the same way as standard solar glass in order to fit the customer production process.
