Solar Photovoltaic Power Generation
Toshiba Plant Systems & Services has an industry-leading track record in the construction of multi-megawatt solar farms.
EPC projects for solar farms with more than one gigawatt of capacity


We constructed our first multi-megawatt solar farm for a power company in 2010. Spurred by the prevalence of feed-in tariff (FIT) programs, we have since constructed solar farms with more than one gigawatt of capacity.
In recent years, multi-megawatt solar farms have been constructed on increasingly diverse terrains and in various climatic regions. We offer design and construction services for solar farms on various terrains and under wide-ranging climatic conditions, including golf courses, former ski slopes (requiring solar array installation on hillsides), marshy places, soft ground, mountainous terrain, and snowy areas.
Key Points
- We have extensive expertise in the commissioning of solar farms and provide comprehensive services, including the handling of a pre-use self-test and safety management examination.
