Greetings from the President

President and CEO Mikio Murozono
Since the Industrial Revolution, human beings have repeatedly consumed large amounts of energy in pursuit of a richer lifestyle, which has led to abnormal weather conditions due to excessive emissions of greenhouse gases.
In order to pass on this beautiful, livable Earth to the next generation in its original form, I believe that we must all work together in our own ways to reduce greenhouse gas emissions.
Since our founding, we have been working on the development of clean and renewable energy. We will continue to aim for further growth in our four business fields with the themes of "energy creation, energy conservation, and the environment."
The first is the design, construction and sales of solar power generation systems. Solar power generation systems have become incredibly cheap, and grid parity has already been achieved. 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 business. We design and construct our own solar power generation systems, and use some of them to generate electricity. We will then utilize this know-how in our maintenance business.
The third is the development and sale of products that support energy creation and energy conservation. We will actively pursue the expansion of our product lineup of energy storage systems, the development and commercialization of lightweight modules for wall installation, and the development of new products for securing power in the event of a disaster.
The fourth is a new environmental business to replace solar power generation. We are considering installing small hydroelectric power generation in multiple locations. We have also started an electricity retail business. We aim to supply electricity generated by our own company as soon as possible.
Through our four business fields, we would like to strive to realize a sustainable recycling-oriented society. We sincerely ask for your continued support and guidance.
Furthermore, production of spherical silicon solar cells, which has been our main business since our founding, will cease at the end of March 2022. We would like to express our sincere gratitude to everyone for the tremendous support we have received regarding these solar cells.
