Background of Introduction

Advertisement for Kasai Water Reclamation Center

In order to reduce the exhaust amount of greenhouse gases by 25% (compared to that in FY 2000) till FY 2020, the Bureau of Sewerage Tokyo Metropolitan Government has been taking action enthusiastically by formulating a new plan to prevent global warming, "Earth Plan 2010". A solar power generation facility was introduced as a part of their policies.
We have been delivering an integrated system of a uniaxial tracking mount in which solar cells move in accordance with the direction of the sun, power conditioners, etc.

Products of supporting Mega Solar

PCS (power conditioner)
Main part of the solar park in which the output from the enormous numbers of solar cells is effectively converted to AC power.
Solar cell
The CIS solar cell manufactured by Solar Frontier K.K. is adopted.
Monitoring and control systems
We implement a system that significantly contributes to the operations of a solar park such as the status of power generation and the condition of equipment. We also propose countermeasures to stabilize the systems that will be required for a solar park in the future by using our technical strength acquired from abundant achievements (Wakkanai Solar Park, China, Laos, etc.).
Interconnection substation
We propose the optimal transformer from our many years of achievement as a heavy electrical machine manufacturer.
