Aiming to create a low carbon society, the most important task is to reduce energy consumption for hot-water supply which covers 1/3 of the total energy consumption in the residential sector. It has been considered that the introduction of a solar thermal system is one of the key solutions, however, its adoption rate remains sluggish recently in Japan. On the other hand, the installation rate of solar water heaters in China is amazingly high and now China has the world’s No1 share of the market. This paper is to report the outline of the research results on the present situation of solar hot water systems in China and its background in order to find new incentives to promote solar thermal systems in Japan.
