Market Overview

Size of the next-generation home equipment market (based on the retailer prices of the following six equipment: HEMS, smart meters, photovoltaic systems, fuel cell systems, household power storage systems, and V2H (Vehicle to Home)) for FY2018 is likely to be 97.7% on Y-o-Y to attain 679.6 billion yen.

Since FY2014 the market size has been on the fall as the retail price of photovoltaic systems that occupy large component ratio in the market has declined, and unit price of equipment has decreased. Nevertheless, the market size of four items of next-generation equipment, other than photovoltaic power generation systems with the market already launched, and smart meters already widely accepted as social infrastructure just as the electric power companies planned, is likely to attain 180.8 billion yen, 160% of the size in FY2014.

Demand for Power Storage Systems Expanding due to 2019 Issue

The promising equipment likely to most contribute to expanding the next-generation home equipment market for the future is household power storage systems. Power storage systems used to be the item “just in case of a disaster.” However, as the government partially ends feed-in tariff system for home solar systems, the demand for captive consumption of excess electricity at the households is likely to increase.


According to the Agency of Natural Resources and Energy, there are 530 thousand households equipped with solar power generation systems to end the 10-year FIT contract in November and December 2019 alone. The makers together with the dealers of household power storage systems are aiming at these post-FIT power customers. The website of household PV has disclosed the results of the questionnaire to the FIT contractors about the majority of the respondents intending to consume the excess electricity by themselves after FIT contract expiration, rather than looking for another buyer, which is raising the expectation of household power storage systems to expand further.

Future Outlook

Prevalence of ZEH in recent years as well as mandatory energy-saving standards, some attempts of reducing consumption of primary energy have been accelerating, which is expected to increase the demand for PV for FY2019 and beyond. Though there are plans to put off making the energy-saving standards mandatory, the market is expected to be on the recovery. The domestic next-generation home equipment market size (based on the retailer prices of total six items) is projected to achieve 789,900 million yen by FY2022, while the market size of four items of next-generation equipment, without photovoltaic power generation systems and smart meters, is likely to attain 364,900 million yen by FY2022, 324% of the size in FY2014.
