Modern photovoltaic (PV) solar modules make exacting material and system demands on marking technology. The labels used for production control, track & trace, branding, and as power-rating and nameplates, must be able to permanently withstand extreme UV and weather conditions. In addition, they have to meet a number of legal requirements. Schreiner ProTech now offers an individual solution for every need.

Today, every single solar PV module is marked with an individual code for production control purposes and definitive traceability. The code is applied in a clearly visible location at the front of the component and has to retain its legibility, even after years of exposure to UV radiation. For this application, Schreiner ProTech has developed an Embedded-Label. It is TTR-printable, dimensionally stable, and applied directly to the EVA (ethylene-vinyl-acetate) sheet of the solar module.

Specialized Branding-Labels, on the other hand, play an important part in communicating and reinforcing the brand’s image. Extremely weather-resistant, they are applied to the solar module’s frame, clearly displaying the manufacturer’s brand logo without any degradation in quality for many years.

Power-Labels have to comply with exacting legal requirements. They are applied to the back of a solar PV module and contain rating data as well as information about the manufacturer. These safety-relevant nameplate labels are generated directly after the flasher test and have to conform to the requirements of EN 50380. Therefore, Schreiner ProTech exclusively uses UL-approved materials and, if required, integrates additional features ensuring maximum anti-tamper safety - such as 2D or 3D holograms.
Tailored Module Branding and Security
Manufacturers seeking reliable protection from product pirates require tamper- and counterfeit-proof marking solutions such as Module-Branding-Labels by Schreiner ProTech. These labels use Color-Laser-Film (CLF), which is laminated into the module. At the end of the process chain, the CLF-Label receives a laser inscription. This process step is performed through all the glass and plastic sheet layers of the solar PV module and produces zero emissions.

Systematic Value Added
Smooth integration into the manufacturer’s production process is of paramount importance to the overall success of the marking solutions used, and the requirements are as varied as the processes themselves. As a development partner of its customers, Schreiner ProTech brings comprehensive systems expertise to any customer project. The company’s experts advise and assist customers in the selection, installation and start-up of the components and systems required to process marking products. This assures viable system solutions which help strengthen the manufacturer’s market position.  

Exceeding Standard Requirements
All of Schreiner ProTech’s solutions for the solar industry have two things in common. First, all materials used have been awarded UL approvals. Second, Schreiner ProTech has performed extensive material and durability tests exceeding the requirements of the solar-specific IEC 61215:2005 standard. In addition, all tests have been validated by TÜV Rheinland, thus providing users with even higher assurance of reliability and safety.
