Nihon Dengyo Kosaku Co Ltd (Chiyoda Ward, Tokyo) announced a wireless monitoring system for solar power plants May 27, 2014.

The company will provide services for small- and middle/large-scale solar power plants by combining its "Mu Sensor" sensor system and "FalconWave" long-range wireless LAN system.

The Mu Sensor is a system that uses a sensor unit equipped a stand-alone power source to monitor a solar power generation system 24 hours a day and report abnormal decreases in the amount of power generated, abnormalities of devices, etc to a manager's mobile phone. The FalconWave is a system that transmits videos being taken by monitoring cameras installed at multiple locations via a wireless LAN, for which a communication fee does not have to be paid.

For small-scale solar power plants, Nihon Dengyo Kosaku will provide a system that enables to monitor the connecting points of PV inverters and the voltages of strings connecting solar panels in series with a mobile device. For middle/large-scale solar power plants, the company will also offer a system that uses IP cameras capable of wireless communication to monitor solar panels via a wireless LAN.

They are stand-alone systems and can be installed even after the introduction of a solar power generation system. The price of a stand-alone sensor unit equipped with a solar panel starts from ¥170,000 (approx US$1,662).
