Solar plants viewer offers customisation

Japan’s Axis Corporation has developed a solar plants viewer which can be used to monitor industrial photovoltaic (PV) generation plants.

When using total power monitoring by power conditioning subsystems, it can be difficult to detect partial failures (decrease in output) caused by PV module troubles, deteriorated cables and partial shading.

Just 1 Mega Watt often needs 3,000 to 4,000 modules and it requires a great amount of time to inspect them to find the source of defects.

The Axis system features separate monitoring for each string allowing the early detection of partial system errors.

This also leads to decreased down time as the specific problematic string can be identified and the faulty module then repaired or replaced.

Takafumi Hayashi of Axis emphasises that customising the software is very simple.

This system does not require a junction box and power collection box for the monitoring equipment. It can be installed on existing PV equipment without the need for any power distribution work.

“The system monitors and records the power generated and solar irradiance and sends out real-time email alarm alerts in case of problems,” Hayashi told PACE.

The integrated screen displays measurement values and camera images from multiple plants.

JETRO promotes trade and investment between Japan and overseas companies.

JETRO organised three companies to attend TiGiS in Taiwan. This Taiwan International Green Industry Show was held early October in Taipei.

PACE attended the event as a guest of TiGiS.
