Business trend of the smart house market
(1/8)
Photovoltaic generation
Facing power shortage due to the March 11
disaster in the Tohoku district, Japan is required to work out measures for an
even more energy-saving society. Supported by IT technology, the smart house
market is growing rapidly and expected to reach 12 trillion yen worldwide in
2020. It covers a wide variety of industries including generation,
energy-saving equipment, sensors, and management systems. This article is the
first of the eight articles on various industrial fields involved in the smart
house market. It focuses on the photovoltaic generation business and the relations
of companies involved in the business.
According to a research firm, the smart
house business excluding housing structure was 2,708 billion yen in 2011 and it
will grow to about 12,000 billion yen in 2020 worldwide. Japan is the largest
market, accounting for 30% of the world market. The business model of smart
house has not been established, but it will ultimately be a smart community
that can supply energy for itself even in a time of disaster through the
collaboration of such distributed power sources as photovoltaic generation,
wind generation, and generation using waste heat and waste materials. In a
sense, efforts for faster recovery of the areas devastated by the March 11
disaster facilitate the growth of the smart house business in Japan.
