Japanese electronics giant Kyocera says it will build a 70-megawatt solar power plant in the southern Japanese city of Kagoshima.

The project, undertaken with partners IHI Corp. and Mizuho Corporate Bank Ltd., will create a "mega-solar plant" to help solve Japan's power supply issues caused by the 2011 earthquake, tsunami and nuclear power plant disaster, Kyocera said in a release Tuesday.

The planned site of the solar power plant will cover about 314 acres of land, roughly the same area as 27 baseball stadiums.

Using 290,000 multicrystalline solar modules manufactured by Kyocera, the project is the largest officially announced solar power plant in Japan.

The annual electricity generated will provide the power for roughly 22,000 average households, will help to offset around 25,000 tons of CO2 per year, and would account for 40 percent of Japan's total current solar electrical output, Kyocera said.

With a projected cost of nearly $310 million, construction of the Kagoshima Nanatsujima Mega-Solar Power Plant is expected to begin in July.
