"Hayahinomine" is an 868m-high mountain in Kitakata-cho, Nobeoka City in northern Miyazaki Prefecture, Japan. From its top can be seen the Sobo-Katamuki-Ookue mountain range and the Aso mountains.

The leisure complex "ETO Land Hayahinomine" is located right below this mountain top. A mega- (large-scale) solar power plant, where solar panels were positioned in shapes like flowers, was constructed in this complex (Fig. 1).

Solar panels were set up as if they were flowers blossoming on the ground staring toward the sun.

The mega-solar plant at ETO Land Hayahinomine was developed and is run by West Holdings group companies.

"We wanted visitors to find the solar plant fun to look at, which is something suitable for a leisure complex in the mountains," said Eiichiro Egashira, a managing director of West Holdings Corp, which led the development of this solar plant.

In addition, compared with other general solar power plants where solar panels are placed as close to each other as possible and arrayed orderly across the site, this plant has many areas with no panels. As a result, the number of panels that could be set up in the site decreased, and the efficiency of panel installment per commercial area was relatively lower (Fig. 2).
