Series OR Series 7 variants
The Peimar OR Series consists of half-cut modules designed to perform reliably in real roof and ground conditions, where factors such as shading losses, high temperatures, and long-term reliability are critical. Dividing the cells in half improves the current distribution within the module, which in practice helps to minimize power losses under partial shading and increases resistance to microcracks that can occur during installation and operation. Depending on the variant, either monofacial or bifacial solutions are available, as well as versions with TOPCon (N-type) technology, which support high efficiency and better long-term performance stability. An additional advantage is the hardened glass with an anti-reflective coating, which improves light absorption and resistance to weather conditions. The OR Series is a good choice for residential, commercial, and industrial installations – particularly where high annual yield, predictable performance, and the flexibility to choose a module for the project are important.
