CdTe Thin Film Technology

Highly efficient thin-film CAT® modules ensure greater performance compared to traditional silicon solar modules. They generate more energy than modules with the same rated power from rival companies. Thin-film CAT® modules offer great performance and reliability to their users.

The CAT PVT series photovoltaic panels are so-called second generation panels, known also as thin-film panels due to their low thickness of merely 6.8mm.

The PVT panels are made with the use of semiconductive material named cadmium telluride (CdTe). Up to now, despite their numerous advantages, thin-film panels were characterized by relatively low performance. We offer modules with efficiency of 16.4% and nominal power of 117.5W and 120W. Soon the offering will be extended to include panels with even higher efficiency, and with nominal power exceeding 400W.

The most important advantages of thin-film solar panels include:

• Low temperature coefficient – 0.28%/°C – smaller energy yield drop in high temperatures compared to silicon technology
• Outstanding spectral response in shade and in higher humidity conditions – power decreases in a linear manner as the module is shaded
• Self-cleaning properties
• No performance induced degradation (PID free)
• Frameless design – no need to earth the module
• ATLAS 25+ mark guarantees high durability of the modules confirmed with relevant tests
• Guaranteed 86% power yield after 25 years of operation
• Small carbon footprint
• Compatible with1,500V systems

Taking the above into account, despite relatively low efficiency of the module, the CdTe panels are capable of achieving performance higher by even 10% compared to the commonly used silicon modules. Thin-film CAT® modules offer great performance and reliability to their users.
