Promoting the use of
Renewable energy

There are different types of renewable energy such as solar, wind, hydro and biomass. Of these, Forchile promotes the solar power generation business. Our services begin from finding sites for building solar power plants to construction and post-power-up maintenance. We provide solutions that meet customer needs across all phases associated with a plant.

Voltage Classification of
Solar Power Generation

There are three voltage classifications for solar power generation, “low voltage”, “high voltage” and “extra high voltage.” Each have different uses and require different construction applications.


Steps to building
a solar power plant
Photovoltaic Power Plant

The following is an example of “extra-high voltage” construction.
When constructing solar power plants, we normally follow these steps

Land acquisition/planning

  • Search for a suitable location to construction the solar power plant and gather various information
  • Perform on-site studies, create plans and designs

Filing of various applications

  • File documents such as required for real estate contracts, and applications that need to be submitted to power companies, and organizations such as the Ministry of Economy, Trade and Industry.

Construction work

  • Develop the land and install base foundation for solar panels
  • Attach solar panels and connect the cables. Once connected to the power company’s power grid the process is complete.

We constructed a 2MW (1,980kW) large-scale solar power plant in Akune, Kagoshima. Here are some details from the construction work.

  • Land development
  • Inspection by
    Kagoshima prefecture
  • Installation of
    base foundation
    and underground cables
  • Attach panels and
    connect cables
  • PCS installation
  • Inspection by
    power company
  • Integrate systems/
