Germany-based Phytonics has developed a self-adhesive film with microstructures to reduce glare on PV modules. It is available in sheets and rolls for new and existing PV systems.
The blinding effect of solar panels often causes arguments between neighbors. At airports, traffic routes and nature reserves, PV modules must meet specific requirements, usually achieved with an anti-reflective coating. However, Germany-based Phytonics says this coating only increases the yield of the panels and does not prevent glare.
Phytonics claims to have developed a self-adhesive film that reduces glare to the necessary extent. The film has special, bionic microstructures that efficiently couple shallow light, making the modules glare-free and increasing performance during off-peak hours.
Phytonics says the film uses materials proven to be long-term stable in outdoor use. It is resistant to UV radiation, moisture, heat and hail. The film is available directly from the company in rolls or sheets for €70 per module sheet, with future pricing depending on several factors.
According to Phytonics, the self-adhesive film can be used for both new and existing PV systems. The company says it is seeing strong demand for its flexible anti-glare solution, which spans all photovoltaic segments.
“We receive questions every day – often due to neighborhood disputes, but also regularly from project developers of PV systems near highways and airports,” says Ruben Hünig, CEO of Phytonics.
The film provides a simple solution against critical glare effects without reorienting the modules or implementing complex visual protection measures. It’s already in use. In Switzerland, for example, it has been applied to modules of a house where the PV system blinded the neighbor. It will soon also be used in a supermarket roof system in Germany, where the building permit required glare-free solar panels.
