XRF anti-glare module

Our pre-coated PV modules are finished by hand with the XRF anti-glare film in our production facility. They are available in various module designs from different manufacturers to meet your specific requirements.

Solar modules equipped with the XRF anti-glare film do not glare even under the most unfavourable conditions. Even at extremely flat angles of incidence of up to 70°, the reflected luminance remains well below a value of 75,000 cd/m². This means that the XRF anti-glare film outperforms other glare-reducing products by far. Due to the optimised, bionic surface structure, flat incident light in particular is coupled in much better, so that the film has hardly any influence on the yield - in the best case, the electricity yield even increases.

The glare problem

Our solution for you

The sun shines with an impressive 1.6 billion candelas per square metre (Cd/m²). For comparison: the human eye is already dazzled from a brightness of 100,000 Cd/m². However, modern anti-reflective coatings still reflect at least 1% of the incident light and glare is inevitable. And the flatter the incidence of light, the more light is reflected.
Technically, the glare potential of a solar module is determined by bidirectional reflectance distribution functions (BRDF). The module is illuminated at different angles of light incidence and the reflected luminance is recorded for each spatial direction. The diagram shows the brightness around the specular point, the case for which the angle of incidence and angle of reflection of the light are the same. This is where the highest values are usually measured. The comparison shows that previous modules advertised as glare-free reflect so strongly at flat incidence of light that the human eye is dazzled.
Our XRF coating, on the other hand, reliably reduces the glare of the solar module across all angles of light incidence and in all cases remains below the critical 100,000 Cd/m².

Performance

Top performance at any time of day

The nominal output of solar modules is measured under standardised conditions and is specified on data sheets and the type plate. However, this value is determined under vertical incidence of light, which usually only rarely occurs in real operation. The output of the solar module changes depending on the orientation of the roof and its inclination, the time of year and the time of day. Reflection increases and therefore the output of the solar module decreases, particularly in the case of flat incidence of light, situations that are particularly common in the morning and evening hours of the day. The reason: modern anti-reflective coatings lose a large part of their functionality here. This loss can be measured and visualised using the "Incident Angle Modifier" (IAM for short). In the best case, this value is always close to 100%, regardless of the angle of incidence of light. From around 50°, modern anti-reflective coatings lose their function - in contrast, the XRF coating from Phytonics retains its function. This is due to a unique microstructure that ensures that the light is always guided efficiently into the solar module - as confirmed by the renowned IMEC research centre in Belgium with its measurements. And your solar system can now benefit from this!

Successful projects from
customer perspective

"The solar panels on the north-facing side of our neighbour's roof were blinding us directly in our living room for months and prevented us from enjoying the beautiful view - the problem was completely solved by the Phytonics coating."
Phytonics Icon Frau Georgi
Neighbour
"We were already in court with our neighbour because of the glare - thanks to the anti-glare coating from Phytonics, we can now continue to generate solar power on our roof."
Phytonics Icon Herr Professor G. Stock
Customer
"As an energy transition enthusiast, I fitted both sides of the roof with solar modules. Unfortunately, I didn't initially consider that glare could disturb my neighbours. Fortunately, Phytonics solved the problem and peace has been restored."
Phytonics Icon Herr P. Schu
Customer
"The reflections from our neighbour's solar system were a major nuisance for us, as we constantly had to draw the curtains and close the blinds. Admittedly, I was sceptical as to whether a coating would solve the problem - the reflections are now no longer visible and we can enjoy the view again undisturbed, the anti-glare effect is really perfect."
