Japan Broadcasting Corp (NHK) announced Aug 6, 2012, that it has completed the construction of a photovoltaic (PV) power generation system at its Shobu-Kuki transmitter in Saitama Prefecture, Japan.
The system will be in full operation Aug 8, 2012. NHK originally planned to complete the construction by the end of 2012.
A total of 8,120 PV panels are used for the system to realize an output power of up to 2MW (2,000kW). The expected annual power production of the system is 2 million kilowatts per hour. When power production is at its peak during daylight hours, the system can produce all the electricity used at the transmitter.
According to documents disclosed by NHK, the total cost for the PV system and its installation is ¥1,194,388,000 (approx US$15,277,411), which is broken down to ¥294,538,000 for Sharp Corp's PV panels, ¥68,250,000 for Toshiba Corp's wiring and power generation/power supply system and ¥831,600,000 for the installation of mounts and the system, which was done by NHK ITEC Inc.
