FAQS about Japan agrivoltaic projects

What is the biggest agrivoltaic installation in Japan?

Mibet, a Chinese mounting system supplier, has completed what it claims is the biggest agrivoltaic installation in Japan. The solar modules for the 4 MW project in Fukushima prefecture were installed on Mibet’s agrivoltaic mounting system. Mibet has announced the successful commission of a 4 MW agrivoltaic plant in Japan.

Are agrivoltaics allowed in Japan?

The Japanese authorities have released new guidelines for the development of agrivoltaics projects and have excluded installations that do not host crops or livestock in the planning phase.

Which agrivoltaic system was installed in Fukushima Prefecture?

The solar modules for the 4 MW project in Fukushima prefecture were installed on Mibet’s agrivoltaic mounting system. Mibet has announced the successful commission of a 4 MW agrivoltaic plant in Japan. The company built the 68,000 square-meter installation on abandoned land in Fukushima prefecture.

How many agrivoltaic projects are there in Japan?

“METI is currently providing a rebate covering 50% of a project's costs, but so far there are about 10 projects of this kind in Japan.” According to recent statistics from the Ministry of Agriculture, Forestry and Fisheries, 200 MW of grid-connected agrivoltaic projects were in operation in Japan by the end of September.

Will agrivoltaics replace solar power plants in Japan?

As a result, the rapid increase in solar power plants under the country's FIT will gradually be replaced by agrivoltaics. The International Renewable Energy Agency (IRENA) recently identified land scarcity and grid congestion as the two main reasons behind the limited success of Japan's six solar auctions.

How agrivoltaics can help the Japanese agriculture?

Farmland must be converted to non-agricultural use to install photovoltaics, in which agrivoltaics has an advantage over solar parks applicable to all 5 classes of farmland. Increase of devastated and abandoned farmland is a grave concern for the Japanese agriculture and agrivoltaics is expected to contribute to solve this issue.
