In an effort to encourage NRE deployment, the government has initiated a program which was called ‘1 million green homes program’. The offical name has been changed from “1 million green homes program” to “Home subsidy program” since 2013. This is one kind of subsidy program to facilitate installing NRE facilities in residential areas such as private houses, multi-family houses and public rental houses.
“1 million green homes program” was launched in 2004 and exiting 100,000 solar-roof installations program was emerged into this project. The government will support a certain portion of total installation cost. Although 100,000 solar-roof deployment project was to install PV system in residential houses, Home subsidy program focuses on a variety of resources such as PV, solar thermal, geo-thermal, and small wind. In addition, there are several types of home which range from detached houses to apartment houses.
