RenewableEnergy

Creating a sustainable future for the planet, the environment, and people through renewable energy.

Abnormal weather caused by global warming, increasing electricity demand driven by the spread of AI, and global population growth are rapidly expanding energy consumption worldwide. As a result, CO₂ emissions are having a significant impact on the future of our planet.

Daisho Sangyo procures the power infrastructure required for renewable energy facilities—such as battery storage systems, aluminum cables, and solar panels—from both domestic and international sources, and provides complete solar power generation systems. Centered on the development of solar power and energy storage systems, we support implementation and operation through an integrated system that includes equipment supply, design, construction management, and electrical work.

We also support the introduction of renewable energy solutions for a wide range of facilities, including factories, warehouses, and commercial buildings.

By changing the way energy is chosen and making CO₂-free electricity the new standard for society, Daisho Sangyo continues to take on the challenge of building a sustainable future where the planet, the environment, and people can thrive together.

Aluminum Cable

Aluminum cables offer several advantages compared to copper cables, including lighter weight, cost reduction, and improved theft prevention.

Because they are lightweight and easy to handle, they improve installation efficiency and help reduce total project costs. Another key advantage is their relatively stable price compared to copper.

As a result, aluminum cables are increasingly being adopted as suitable power infrastructure for renewable energy facilities such as solar power generation systems and energy storage systems.

Product List

  • We specialize in the design and fabrication of heat exchangers, pressure vessels, and equipment units associated with large industrial rotating machinery such as turbines, generators, and compressors, including shell-and-tube oil coolers, aluminum fin-tube hydrogen and air coolers, and air-cooled heat exchangers (air fin coolers).

  • • CV, CVD, CVT, etc.
  • • AC Cables: Available from low to high voltage 600V (JET Certified), 0.6/1kV, 1500V, 3300V, 6600V (JET Certification in Progress)
  • • DC Cables: Solar power cables such as 1500V copper cables

  • We propose the most suitable cables for power infrastructure applications such as solar power generation systems and energy storage systems.

Lightweight Thin Solar Panels

These are lightweight and flexible solar panels.
Because they can be installed while reducing the load on rooftops, they are suitable for buildings with limited load capacity as well as aging facilities.

They can also be installed in locations where conventional panels are difficult to use—such as curved roofs—expanding the range of places where solar power systems can be deployed.

Product List

  • • Framed Type: 10.8–13 kg Can be installed using the same installation methods as conventional glass panels.
  • • Frameless Type: 7.9–9.5 kg Lightweight design suitable for installation on walls and other surfaces.
  • • Agrivoltaic Type: 6.2 kg Supports transparent bifacial power generation and is suitable for agrivoltaic solar power systems.
  • • Black Type: 6.3 kg Suitable for installations where appearance is important, such as residential rooftops.

  • We also handle glass solar modules from various manufacturers. Please feel free to contact us for more details.

Sodium-Ion Batteries

Sodium-ion batteries are next-generation energy storage systems that utilize abundant sodium resources found in seawater and salt. They are expected to offer high safety and strong performance in low-temperature environments, making them suitable for use in cold regions and outdoor facilities.

They are increasingly being adopted as energy storage systems combined with solar power generation and are gaining attention as a key storage technology supporting the expansion of renewable energy.

Model List

  • We offer models suitable for a wide range of applications, including industrial energy storage systems and large-scale energy storage plants.

  • Applications are currently being prepared for the introduction of sodium-ion batteries in Japan.
