The generator is made of about 4,740 panels, each of which measures about 1.3 meters in length and about one meter in width. The panels are placed in three different locations in the plant, covering a total area of about 6,300 square meters. The generator's maximum generating capacity surpassed that of a similar facility in the Hyogo prefectural government's Nishiharima branch in Kamigoricho, which has a peak output of 506 kilowatt-hours.
The filtration plant annually used about 11.5 million kilowatts of electricity costing 138 million yen. The photovoltaic power generator, which cost 562 million yen to build and will annually supply 810,000 kilowatts of electricity, the equivalent use of about 220 households, is expected to reduce carbon dioxide emissions by 208 tons.
The prefectural government's waterworks bureau said the maximum output will surpass 790 kilowatt-hours during fine days in midsummer. Even on cloudy days, the facility can generate 120 kilowatt-hours to 130 kilowatt-hours of electricity.
