About this web site

As countries adopted systems that allow power companies to purchase electricity generated using renewable energy sources for a long term at a flat rate (feed-in tariff), large-scale photovoltaic (PV) power plants with capacities over 1,000kW or 1MW ("mega-solar" power plants) are being constructed one after another. To stably operate such PV power plants for a long term, high technologies are required, and various risks are involved. To ensure that the budding mega-solar market will grow in a sustainable way and that related industries will grow and develop soundly, it is necessary to accurately understand the situations in and outside our country as well as carefully watch the latest trends. On this website, we will support the sound growth of the mega-solar market and the development of related industries by providing information collected through a wide range of researches.

Mega Solar Business provides the following two kinds of contents.


We post a domestic or foreign news article about mega-solar business every day.

Visit to Plant

Mega-solar power plants (large-scale PV power plants) have begun to be constructed in various regions across Japan, and some of them have already started operations. We visit those plants, interview relevant people, examine how the projects were launched and report their backgrounds and episodes.
