About Us

Greetings
Greetings from the President
To pass on our beautiful Earth to the next generation. 
We contribute to the realization of a carbon-free society through "energy creation, energy conservation, and the environment."
As a company, we have a significant responsibility to address the global issue of climate change. 
Since our founding, we have continued to take on the challenge of realizing a sustainable society, with clean energy development at our core. The renewable energy market has now moved beyond a period of dependence on subsidy systems (FIT/FIP) and is entering a period of self-reliance and widespread adoption, where true economic rationality will be put to the test. We see this period of transition as an opportunity and aim for further growth in the following three business areas.

  1. Solar Power Generation Solutions With the achievement of grid parity (costs equivalent to existing electricity), we will establish a business model that does not rely on subsidies. We will accelerate the introduction of renewable energy in both "on-site" areas where electricity is generated in the area of ​​consumption, and "off-site" areas where electricity is supplied from remote locations.
  2.  Storage Battery System Business "Solar Power Combined Type" aims to reduce costs and ensure stable supply (BCP measures) through self-consumption, and "Grid Connected Type" contributes to adjusting supply and demand by utilizing price differences in the electricity market. These two approaches enable efficient energy management.
  3. Power generation business and O&M (maintenance and management) We own power plants that we designed and constructed ourselves, and are looking to expand into direct power supply (PPA) to end users. In addition, we utilize the technical capabilities we have cultivated over many years to take on a wide range of maintenance and repair work, not just for our own construction projects, and support the stable operation of infrastructure.

As energy professionals, we will continue to strive to build a recycling-oriented society where the environment and the economy are in harmony. We sincerely ask for your continued support and guidance.

*Notice: Production of spherical silicon solar cells, which we have been working on since our founding, will end at the end of March 2022. We would like to express our deepest gratitude for your patronage and support over the years.
