No-Rail Solution for Standing Seam Metal Roof

Located in Japan, this 450KW rooftop photovoltaic project is installed on a standing seam metal roof, a common roofing structure in industrial and residential buildings across Japan.

To suit the unique characteristics of the standing seam roof, the SOEASY team provided a railless clamping solution. Instead of traditional rails, this system utilizes specialized clamps that directly fix onto the vertical seams of the roof without the need for roof penetration. This method not only ensures quick and secure installation, but also protects the roof structure and lowers overall material costs.

Key Features:

• No drilling or penetration, preserving roof integrity
• Lightweight and labor-saving structure
• Simplified logistics with fewer components
• Clean, low-profile appearance suitable for residential areas

The entire system is engineered for high wind and snow loads typical in Japan, while minimizing visual impact and maintenance complexity. This project showcases SOEASY’s ability to deliver efficient, tailored solar mounting solutions that balance performance and cost.
