Renewable Engry Product Business
Since August 2012, we have been developing and operating green power generation projects, primarily focused on solar energy. Our track record includes the construction of hundreds of low-voltage solar power plants, alongside a strong emphasis on high-voltage mega solar projects.
To date, we have developed and constructed a total of nine mega solar facilities and several low-voltage solar plants across the Kanto, Tohoku, Chugoku, and Chubu regions, with a combined ownership capacity of 20 megawatts.
Looking ahead, we will continue to acquire FIT-certified power plants and construct both on-site and off-site solar installations. In addition, we are actively exploring the development of battery storage facilities to complement green power and enhance energy resilience.
Flexible Solar Panels
To bring solar energy to a wider range of buildings and locations,
we manufacture and supply flexible solar panels while also offering EPC services.
Through these efforts, we are committed to accelerating the adoption of solar power systems wherever possible.

VA5-F Series
Compared to traditional solar panels encased in glass and framed in aluminum, our VAS-F series
This substantial weight reduction allows installation on rooftops and walls that were previously unsuitable due to structural load limitations, including aging waterproof sheets and lightweight roofing.
With cutting-edge technology, these panels feature a distinct combination of characteristics:
- Module dimensions: 1840 × 1040 × 2.5 mm
- Weight: 5.7 kg
- Weight per unit area: 2.98 kg/m²
- Output capacity: 360–385 W
- Cell size: 166 mm (half-cut)
How Flexible Are Our Modules?
We tested a 1.84-meter-long flexible panel by bending it with a 0.5-meter radius and letting it sit for 10 minutes.
No visible cracks or structural damage were observed.
These panels can be installed on curved surfaces such as gymnasium roofs, corrugated slate roofing, and flat roofs in regions without snowfall.

Energy storage system
As renewable energy adoption continues to grow, the demand for energy storage systems,
especially for self-consumption solar installations, is increasing.
Additionally, national policies are promoting the development of utility-scale storage facilities to enhance grid flexibility.
For nearly a decade, we have been researching and prototyping advanced battery storage systems.
We are now planning to roll out the following product lineup:

Solar Mount System
Since 2012, we have supplied several hundred megawatts worth of ground-mounted racking systems, using galvanized steel and aluminum structures.
We also design and manufacture rooftop mounting systems and specialized brackets.
Beyond standard offerings, we are proud to be one of the industry’s pioneers in providing custom and specialty mounting solutions.
Carport Mounts
We offer a wide range of carport mounting systems with full end-to-end support—from design and engineering to installation and completion.
ZAM-Coated Steel Mounts
Our mounts made from corrosion-resistant ZAM steel (Zinc-Aluminum-Magnesium) are ideal for coastal areas and snow-heavy regions. Compared to aluminum or galvanized steel mounts, ZAM mounts offer superior durability, exceptional corrosion resistance, and lighter weight.
Greater strength and durability than aluminum frames
Superior corrosion resistance compared to hot-dip galvanized steel, while also offering significantly reduced weight
