Achieve a 28% reduction in electricity costs and maintain profit margins with self-consumption solar power for the precision metal processing manufacturing industry. There are models available with zero initial costs and the use of subsidies.

[Our Construction Numbers and Client List] Total construction cost of 908.4 billion yen, with 83 solar power plants built over 12 years. Clients include Sharp, Panasonic, Daiwa House, Nomura Securities, Mitsubishi HC Capital, JA Mitsui Leasing, DMM.com, KKR, Macquarie Capital, Canadian Solar, Trina Solar, J Holdings, RE100 Power, Excelsior Japan, WindSmile, B&M Asset Management, AD Works, Sparks Asset Management, Etrion, and many others. Simultaneously reduce costs and CO₂ without stopping high-precision manufacturing equipment! *For more details, please refer to the related links or feel free to contact us. ■ Do you have any of these concerns? Electricity costs for machining centers and NC lathes are skyrocketing. Peak power is high due to 24-hour operation. Clients are demanding compliance with ESG/SDGs. ■ Comparison Before and After Implementation Before: Cutting, polishing, heat treatment → High electricity costs After implementation: Same processes + self-consumption of daytime power from rooftop solar → Approximately 28% reduction in electricity costs, increased corporate value through CO₂ reduction - Target subsidies: Ministry of Economy, Trade and Industry "Next-Generation Technology Development Demonstration Project Subsidy"
