Entire array blown away
The strong wind of Typhoon No. 21, which hit the Shikoku and Kinki regions Sept 4, 2018, caused widespread damage to the region.
In Takamatsu City, Kagawa Prefecture, part of some solar power generation equipment installed on sloping ground was blown by the strong wind onto a utility pole and transmission lines below the slope (Fig. 25).
It seems that the array flew like a kite, and the scene of the array with a mounting base hanging on the transmission lines and utility pole is shocking. The array consists of many solar panels. It looks like the mounting system was built by single pipes (Fig. 26).
The utility pole and transmission lines are in Asano, Kagawa Town, Takamatsu City and the lines cross a city road. The city road was closed by Takamatsu City to ensure safety.
A power failure, which seems to have been caused by the incident, occurred in the surrounding areas. The power failure affected about 500 households for approximately six hours and 40 minutes.
Takamatsu City contacted the power producer, which removed the solar panel array on the transmission lines and utility pole. In a case where the power producer is unknown, the city contacts the land owner, because the city can easily find out who the landowner is.
