Fuji Keizai Co Ltd announced its prediction Oct 15, 2019, that the Japanese market for self-consumption-type solar power plants will grow from ¥236.5 billion (approx US$2.18 billion, predicted value) in fiscal 2019 to ¥769.4 billion in fiscal 2030.

According to the prediction, the solar power generation market will shift from the power-selling type based on the feed-in tariff (FIT) scheme to a self-consumption type.

In terms of output, in fiscal 2019, the scales of the markets for residential and non-residential self-consumption-type solar power generation (PV) systems are expected to be 450MW and 440MW, respectively, which Fuji Keizai predicts will grow to 1,350MW and 3,450MW (4.8GW in total) by fiscal 2030.

As for residential systems, the numbers of ZEHs (net zero energy houses) and residential houses that introduce storage battery systems will increase. In regard to non-residential systems, the demand for products that (1) contribute to the environmental strategies of companies pushing forward with ESG investment and (2) reduce electricity costs is expected to grow. And Fuji Keizai predicts that self-consumption-type non-residential PV systems will account for half of all the non-residential PV systems in fiscal 2023 or 2024.

Also, the scale of the "post-FIT" power market including services of purchasing and storing surplus electricity is expected to be ¥4 billion in fiscal 2019 and ¥40.9 billion in fiscal 2030.
