R121
Kseng
The Kseng R121 Tile Roof Solar Mounting System is a photovoltaic mounting solution designed for installing solar panels on tiled roofs. It combines a high-strength aluminum mounting rail, premium aluminum roof hooks and stainless steel fasteners to provide a secure and durable foundation for rooftop PV systems.
The R121 is suitable for residential and commercial tiled-roof solar projects and is designed for fast, efficient installation.
The R121 uses a dedicated tile roof hook structure to connect the solar mounting rail securely to the roof structure. The hook design is suitable for tiled roof applications and helps provide a stable mounting interface for PV modules.
The system uses dual-purpose mid and end clamps to simplify solar panel installation. The clamp design helps secure PV modules while reducing the number of different components required during installation.
The R121 features a quick connector that enables the mounting rail to be connected efficiently during installation. This helps simplify assembly and can improve installation efficiency on the job site.
The roof hook is made from AL6005-T5 aluminum, providing a lightweight and corrosion-resistant mounting component for rooftop solar applications.
The system uses SUS304 stainless steel components for reliable fastening and corrosion resistance in outdoor rooftop environments.
The R121 has been applied in solar projects in Europe and is supplied with relevant certification documentation shown in the product materials, including CE and ETN certification.

The general installation process includes the following steps:
Check the roof structure, tile condition and installation area before mounting the PV system.
Position the premium aluminum roof hooks at the required locations and fasten them securely to the roof structure.
Connect the mounting rails to the roof hooks and adjust their position according to the PV module layout.
Use the quick rail connector to join mounting rails where additional rail length is required.
Position the PV modules on the rails and secure them using the R121 mid and end clamps.
Check all mechanical connections, module alignment and fasteners before completing the installation.
