Kyowa Holdings Launches Next-Generation Flat-Roof Mounting System "STRUCK"
Kyowa Holdings Co., Ltd. is launching "STRUCK," a next-generation flat-roof mounting system for solar power generation facilities, on April 1, 2026. Developed from the real-world perspective of solar EPC construction, it addresses on-site challenges like varying building conditions, waterproofing integrity, wind and seismic resistance, and weight limitations for safer and more efficient solar panel installation.

Kyowa Holdings Launches Next-Generation Flat-Roof Mounting System "STRUCK"
Kyowa Holdings Co., Ltd. (Headquarters: Shibuya-ku, Tokyo, Representative Director and President: Kazuya Tatematsu) will launch "STRUCK," a solar mounting system for flat roofs developed from the real-world perspective of solar power generation facility installation work, on April 1, 2026.
Why we created this mounting system
Kyowa Holdings is a company that has handled its own EPC (Engineering, Procurement, Construction, and O&M) business for solar power generation. That's why we deeply understand not only design but also on-site challenges.
Conditions vary for each building, including slopes, differences in level, and waterproofing layers. Fixing systems while maintaining waterproofing guarantees. Designing for genuine peace of mind against typhoons and earthquakes. And enabling workers on-site to handle it "easily and accurately."
A mounting system that met all these requirements did not exist in the market. That's why we decided to create it ourselves. That is "STRUCK."
"STRUCK" is a coined word from "structure" × "Rack." It embodies the ease of adjustment that "snaps" into place, the ease of construction that makes it "easy" to handle, and the meaning of "struck" = leaving a deep impression.
Four walls we have repeatedly faced on-site
As an EPC business operator, the challenges we have repeatedly experienced on-site have directly become the development themes for STRUCK.
- **Design burden: Conditions change for each building, requiring individual design and on-site adjustments each time.**
- **Construction complexity: Increased construction period and impact on waterproofing warranty due to drilling and anchoring into the waterproofing layer.**
- **Anxiety about wind and seismic resistance: Especially the risk of wind load at roof edges and corners. Compromise is unacceptable in a country prone to typhoons and earthquakes.**
- **Weight barrier: There are endless cases where heavy mounting systems cannot be used due to the load capacity limits of existing buildings.**
These are not theoretical problems but walls we have repeatedly faced ourselves at construction sites.
