Schreiner ProTech, Southfield, MI, USA, a division of Germany based Schreiner Group GmbH & Co. KG, has introduced a product line designed specifically for solar cell applications. The company has developed three labels designed to withstand rigorous outdoor environments while also delivering long-term branding value to manufacturers.

The three products are Embedded Labels, Power Labels, and Branding Labels. According to a Schreiner ProTech press release, “Modern photovoltaic (PV) solar modules stress both material and system demands of marking technology. Labels used for production control, track and trace, branding, power rating, and nameplates must be able to permanently withstand extreme UV and weather conditions, as well as meet a number of legal requirements. Schreiner ProTech now offers an individual solution for every need.”

Embedded Labels are TTR-printable, dimensionally stable labels applied directly to the EVA (ethylene-vinyl-acetate) sheet of the solar module. They address the requirement that every solar PV module manufactured today is marked with an individual code for production control purposes and definitive traceability.

The Power Labels communicate power rating data and manufacturer information on the back of solar PV modules, and are fully compliant with legal requirements. These nameplate labels conform to the requirements of EN 50380 and are generated directly after the module’s flasher test.

The Branding Labels communicate and reinforce the PV module manufacturer’s brand image. Extremely weather-resistant, they are applied to the solar module’s frame, clearly displaying the manufacturer logo without experiencing any quality degradation for many years. The labels use Color Laser Film (CLF) technology, laminating the label into each module, and receiving a laser inscription through all glass and plastic sheet layers of the solar PV surface at the end of the manufacturing process. It produces zero emissions, and serves as a tamper- and counterfeit-proof marking system.
