Solar Frontier builds megasolar plant on wooden mountings

In what it describes as "an unusual occurrence," Solar Frontier has begun construction of a megasolar plant in Japan that uses mountings made of lumber.

The 1.4 MW plant is scheduled to begin operation in May in the Yatsushiro region of Japan’s Kumamoto prefecture.

SF Solar Power, a company jointly founded by Solar Frontier and the Development Bank of Japan (DBJ), is overseeing the project.

Japanese wood preservation technology specialist Xyence, the plant’s leaseholder, will use its knowhow for the plant’s unique wooden mountings, according to Solar Frontier. The wooden mountings, made of Japanese timber, will comprise about 20% of all the mountings at the power plant facility.

High resistance to salt air damage and low thermal conductivity were important factors in choosing wooden mountings for this project, the company added.

"These characteristics will result in less damage from salt air in coastal areas and the effects of snow melting agents. The wooden mountings also offer better resistance to the effects of heat under strong sun conditions. In addition, once the domestically sourced lumber has been dismantled at the end of its life, it can be used to power woody biomass power plants, thereby reducing the project’s environmental impact."
