The interpretation of the development of photovoltaic industry in Germany and Japan(2)

"One project and two projects"

In the Eastern Hemisphere, the Ministry of Economy, Trade and Industry of Japan started implementing the "New Sunshine Project" in 1993, striving to establish Japan's domestic solar photovoltaic industry and the domestic solar energy market. Through a series of government funding and related research, development, demonstration, and deployment, Japan has made great strides in solar cell manufacturing technology and reducing costs.

Global warming and high energy prices have forced Japan, an 85% coal-importing country, to place the photovoltaic industry on the top priority for national development. The Ministry of Economy, Trade and Industry of Japan uses various measures and projects to develop its own photovoltaic industry and capacity, including "New Sunshine Project", "Research and Development Plan for Photovoltaic Power Generation Technology for 5 Years" and "Residential PV System Promotion Plan."

In this process, the Ministry of Economy, Trade and Industry of Japan has always paid attention to the coordination of the development of industrial productivity and consumer demand, and has made incredible results: Nearly 500,000 households have installed solar roof systems, and the cost of solar energy has been greatly reduced.

In 1994, installing a solar system on a Japanese roof cost US$60,000. By 2005, the installation cost has dropped to 20,000 U.S. dollars, and the photovoltaic industry has the ability to compete with other energy sources in Japan.

Soon, Japan ended government funding for the roof system. At this time, Japan already has many of the world's top solar companies.

Japan’s success can be attributed to the fact that the government has paid attention to the coordination of public investment in each stage of solar energy innovation—not only to fund research and development, but also to display research results and invest in early deployments. Work hard.
