[Case Study] Solar Power: Independent Power Supply System

[Case Study] Solar Power: Independent Power Supply System

This is a proposal for utilizing solar power as an independent power source. It serves as a new power source in environments without electricity.

While full purchase and surplus purchase of renewable energy, such as solar power, tend to attract attention, how about introducing solar power as an independent power source? Of course, procedures like FIT are not necessary. Our company proposes independent power supply systems that can power electrical appliances, based on our extensive track record and experience. ◆ As a power source for lighting and pumps on houseboats. ◆ As a power source for lighting in prefabricated huts at construction sites. ◆ As a power source for temporary facilities at event venues. The possibilities are endless, depending on your ideas!
