The solar power system installed at Sony EMCS Corporation's Service Togane Site can generate 200 kW, enough for a neighborhood of about 50 homes. Lead-free solder in the solar cells lightens the environmental impact at the time of disposal. Additionally, instead of conventional fabrication with steel in the frame, special metal fixtures enable direct installation of solar panels on roofs. This new approach greatly reduces the weight and requires fewer resources.

Green Power Certification purchasing and deployment of small wind power stations has raised the level of renewable energy usage to approximately 16% for the entire site.
