Continued from Fukaden's Drone Employed for 7.5MW Solar Plant (1)

Also used at mega solar power plant on 30-degree slope

The mega solar power plant with 1.2MW output in Owase City, Mie Prefecture, that the Fukaden Group developed and operates features another environment that can benefit from inspection by drone (Fig. 4).

Because the solar panels are installed on a slope of about 30°, it is difficult to walk around the site carrying an infrared camera to film the panels, in terms of safety control and cost. For inspection by walking, scaffolds need to be installed to ensure safety.

Therefore, the thermal distribution images of the panels are taken using a drone once every two months. The taking can be completed within 30 minutes using a drone because the scale is smaller compared with Mega Solar Taketoyo.

The data obtained by taking the images of the panels in a manner similar to scanning the site is imported to a PC after the flight to identify the panels with abnormal heat distribution (Fig. 5). Overheating panels are identified at a glance by mapping the thermal distribution images of panels on the plant site map.
