NTT Facilities Inc announced June 13, 2014, that it has started to construct a 2.261MW solar power plant in Tsuchiura City, Ibaraki Prefecture, Japan.
The plant, "F Tsuchiura II Solar Power Plant," will be the company's second mega (large-scale) solar power plant in the city. The plant will be built on privately-owned land. The construction work started June 9, 2014. NTT Facilities plans to start power generation in mid-November 2014. The plant is expected to generate about 2,420MWh of electricity, which is equivalent to the amount consumed by about 670 households.
NTT Facilities will install its own "power generation diagnosis system" and use it for detecting troubles and defects that can hardly be noticed at an early stage and determining whether the amount of power generated is appropriate.
Specifically, it is possible to visualize power generation capability based on diagnosis report and facilitate operation and maintenance using automatic remote diagnosis. Also, the comparative evaluation of power generation state can be performed for each string, which connects 11-19 panel in series, connecting box and PV inverter.
NTT Facilities employed solar panels manufactured by Wuxi Suntech Power Co Ltd and Kyocera Corp and PV inverter manufactured by Toshiba Mitsubishi-Electric Industrial Systems Corp (TMEIC). The panels of the two manufacturers were employed to build up know-how on solar power generation, NTT Facilities said.
