Anti-glare film
The solution for glare issues in a wide range of applications! Our self-adhesive anti-glare film can be retrofitted onto solar modules. All solar modules equipped with standard solar glass are suitable for retrofitting. Even solar modules that are already installed are eligible for retrofitting with the anti-glare film!
The product consists of an extremely UV- and weather-resistant adhesive film coated with a scratch-resistant, surface-textured special layer. A special surface structuring on the micrometer scale provides the outstanding anti-glare properties.
The materials used ensure long-term durability and optimal performance, even under the harshest environmental conditions.
Why do solar modules cause glare?
The sun shines with an impressive 1.6 billion candelas per square meter (cd/m²). For comparison: the human eye is already dazzled at a brightness of 100,000 cd/m². However, even modern anti-reflective coatings still reflect at least 1% of the incident light, so glare is inevitable. And the shallower the angle of incidence, the more light is reflected.
From when does glare occur?
Technically, the perceived brightness of a solar module is determined by bidirectional reflectance distribution functions (BRDF). The solar module is illuminated under various angles of incidence, and the reflected brightness is recorded for each spatial direction. The diagram shows the brightness around the specular point, the case where the angles of incidence and reflection of the light are equal. This is usually where the highest values are measured. The comparison shows that modules previously advertised as glare-free reflect so strongly at shallow angles of incidence that the human eye is dazzled.
Our anti-glare technology, on the other hand, reliably reduces the glare of the solar module across all angles of incidence and is therefore considered "low-glare" according to the definition by Prof. Christoph Bucher (Bern University of Applied Sciences).
For an optimal result, we recommend involving a sign maker or film applicator for the application of the XRF Anti-glare film. We are happy to connect you with one of our partners in your region.
Do you want to apply the film yourself? That is also possible! Please follow our installation video (YouTube) or the step-by-step instructions.
