About Us

Greetings from the President

President and CEO Mikio Murozono
The world economy has been hit hard by the new coronavirus.Vaccination has already progressed and its effects have been confirmed, but it seems that it will take some time for this turmoil to settle.We are now experiencing the gratitude of having a daily life as a matter of course.
Since the Industrial Revolution, we human beings have repeatedly consumed a large amount of energy, causing abnormal weather due to excessive greenhouse gas emissions.The threat of coronavirus may be avoided by vaccines.However, there is no vaccine to prevent extreme weather.The only solution is a global, long-term, steady effort.
We would like to contribute to society through the design, development and sales of solar power generation systems and environment-related products in order to pass on this beautiful and livable earth to the next generation as it is.Based on the unique technology we have accumulated so far, we are aiming for further growth in four business fields with the theme of "energy creation, energy saving, and environment".
The first is the design, construction, and sales of photovoltaic power generation systems.The price of solar power generation systems in Japan has been dramatically reduced, and "grid parity" has already been achieved. The market is expected to expand further from FIT to self-consumption.We aim to aggressively expand our business in this field.
The second is the power generation business using solar power generation systems and the maintenance / maintenance business.We design and construct solar power generation systems in-house, and use some of them to become a power generation company.And we will actively utilize those know-how in the maintenance and maintenance business.
The third is the development and sale of original products such as road studs, sterilizers / deodorizers, and small power storage systems.Road studs and uniquely structured sterilizers and deodorizers have already been well received.The compact power storage system will further enhance the product lineup.We will continue to develop new products that meet market needs.
The fourth is a new energy creation and environment-related business that replaces solar power generation.We are already considering installing small hydropower plants at multiple locations.We have also started an electricity retail business for low-voltage power receiving customers.In the future, we aim to supply electricity from our own power generation.
We would like to contribute to society with new technology for the realization of a sustainable sound material-cycle society through four business fields.
We sincerely ask for your warm support and guidance.
