We will make every effort to research the way of resource conservation.

Fossil fuels such as oil and natural gas provide us with a comfortable life style.However, they also have a serious negative impact on the environment and are partially to blame for global warming.
That's why environmentally-friendly photovoltaic power generation is gaining in significance, especially since it is a renewable energy source that is available without limits.
SANYO is leading the way in research and development as a pioneer in the field of photovoltaic power generations. SANYO's solar technology is making an important contribution to improve living standard in an environmentally-friendly way and it is leading us into a bright future.

Large-Scale Solar Power Generation Facility
The design of the Solar Ark was inspired by the vision of an ark embarking onto a journey toward the 21st Century. Only four columns are used to support the entire structure, thus giving the impression of floating in the air.

More than 30 years of experience in solar technology has earned us a reputation for reliability among our customers.
