The TS ShortRail is an optimized rail system specifically designed for vertical mounting of PV modules on trapezoidal and corrugated metal pitched roofs. This system is engineered to provide a lightweight and cost-effective solution for PV module installation. Due to its ultralight design, the TS ShortRail reduces the material requirements for the installation of PV modules on metal pitched roofs. This not only lowers the overall weight load on the roof but also reduces material costs, making it a more economical option for PV module installation. With the TS ShortRail system, Tehnosol offers a streamlined and efficient solution for vertical mounting of PV modules on metal pitched roofs. The lightweight nature of the system simplifies the installation process, while also providing the necessary structural support for secure PV module attachment.
