Developed by Pacifico Energy, the Hosoe Mega solar project is anticipated to be the largest solar power project in Kyushu.
Planned to built on 140ha of land, the plant is expected to enter into service in 2018.
The project will generate clean electricity enough to power about 30,000 households, and displace 68,200 tons of CO2 emissions annually when compared to coal-generated power.
The agreement follows Trina Solar’s 116MW module supply agreement with Toyo Engineering.
Under the previous deal, which was signed in April this year,Trina Solar agreed to supply 446,000 pieces of its TSM-260PC05A modules for a project in Setouchi City, Okayama Prefecture.
Trina Solar Japan president Ye Chen said: "We are thrilled to be partnering again with Toyo Engineering for another large supply agreement.
"With cumulative installations of 6.5GW over the past three quarters, Japan remains one of the key markets for us, and the share of solar in the energy mix for the country is expected to further increase.
"We will carry on executing our growth strategies in the residential, mega solar and commercial segments while further diversifying our client base to expand our footprint in Japan’s solar market. "
