As part of our continuous involvement in the Japanese solar market,  we again take stock of the solar asset ownership in the Japanese market, also comparing the current status to last year's situation to reflect on the changes regarding PV plant ownership. We have come up with a ‘Top 30’, for which we have considered industrial and utility-scale plants with a capacity above 10 kW. It can be seen that the market has remained highly dynamic, with many owners increasing the capacity of their solar portfolios.

Below we share an overview of the largest operational Solar PV Portfolios in Japan, as per the end of 2016. The below overview consists of  the  30 largest portfolios, which together account for 3.6 GW of capacity. This is an increase of almost 10% comparing to the same period of the previous year (3.3 GW by the end of 2015).. Find out more in our article analyzing the market status
