NOWOFLON ET Solar Energy

NOWOFLON ET Solar Energy: Perfect fluoropolymer film for solar thermal and photovoltaic applications

NOWOFLON ET Solar Energy is NOWOFOL's unique ETFE film for surface protection of photovoltaic modules, as well as a convection barrier for solar collectors.

NOWOFLON ET solar energy is a fluoropolymer film (ETFE), which was developed specifically as a convection barrier for solar collectors, as well as for the surface protection of photovoltaic modules. Customers in the solar and photovoltaic industry count on NOWOFLON ET for solar energy in production because the special film provides reliable protection and improved performance.

The highly transparent, weather-resistant and anti-adhesive ETFE film is used for the front and rear surface protection of photovoltaic modules.The fluoropolymer film for photovoltaic modules provides a strong dirt-repellent effect to the outside, while on the inside it allows a strong connection to the encapsulation film.

The ETFE film can also be used effectively to substitute glass in the front sheet area and thus significantly reduce the weight of the modules.In the manufacture of solar collectors, NOWOFLON ET offers a significant increase in performance due to its extremely high thermal resistance as a convection barrier.
