Anti-glare film
Anti-glare film
The solution for glare problems in a wide range of applications! Our self-adhesive anti-glare film can be applied retroactively to solar modules. All solar modules that use standard solar glass are suitable for retrofitting. Even solar modules that are already installed can be retrofitted 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 ensures the outstanding anti-glare properties.
The materials used provide long-lasting durability and optimal performance, even under the harshest environmental conditions.
Why do solar panels 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. Even modern anti-reflective coatings still reflect at least 1% of the incoming 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 from various angles of incidence, and the reflected brightness is measured for each spatial direction. The diagram shows the brightness around the specular point, the case where the angles of incidence and reflection are equal. This is usually where the highest values are recorded. The comparison shows that previously marketed anti-glare modules reflect so strongly at shallow angles of incidence that they cause glare to the human eye.
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 optimal results, we recommend involving a sign technician or film applicator for the installation of the XRF Anti-glare film. We are happy to connect you with one of our partners in your region.
Want to apply the film yourself? That’s possible too! Just follow our installation video (YouTube) or the step-by-step guide.
